It suggests that ozone depletion in certain seasons and at certain latitudes may be larger than predicted by current atmospheric models and that "the observed changes may be due wholly, or in part, to the increased atmospheric abundance of trace gases, primarily chlorofluorocarbons (CFCs)." Atmospheric scientists are attempting to understand and model the mechanisms that have produced ozone declines. Such improvements in understanding and models would allow for more accurate assessments of future risks of ozone depletion. This report presents a method for evaluating risks that avoids the uncertainties currently involved in linking atmospheric chlorine and bromine levels and projected ozone depletion. Instead, it relates rates of emissions to stratospheric levels of chlorine and bromine. Because chlorine and bromine concentrations ultimately determine risk, this approach, although imperfect, aids in assessing the potential risk of additional ozone depletion. Using this approach, potential changes to the current levels of chlorine and bromine that could occur under various emission scenarios, including the Montreal Protocol, are projected along with the relative contribution of different chemicals (e.g., CFC-11; CFC-12; CFC-113; methyl chloroform; HCFC-22, etc.) to these changes. The report also examines the reductions in potential ozone depleters needed in order to stabilize the atmosphere at current levels of chlorine and bromine. Finally, the chlorine levels associated with various changes in the coverage, timing, and stringency of the Montreal Protocol are projected. FINDINGS 1. Based on reductions required under the Montreal Protocol and assuming substantial global participation, chlorine and bromine levels will increase substantially from current levels. o By 2075, even with 100 percent global participation in the Protocol, chlorine abundance is projected to grow by a factor of three to over 8 ppbv from current levels of about 2.7 ppbv, assuming methyl chloroform emissions grow. o If methyl chloroform emissions do not grow, either due to global agreement on emission restrictions or due to a lack of demand, chlorine levels would still grow to over 6 ppbv by 2075, even with 100 percent participation in the Montreal Protocol. o Because of long atmospheric residence times and transport delays to the stratosphere, stratospheric chlorine levels will continue to grow for about 6-8 years even if emissions were totally eliminated. ------- -2- 2. An immediate 100 percent reduction in the use of all fully-halogenated compounds and a freeze in methyl chloroform would be needed to essentially stabilize chlorine and halon atmospheric abundances at current levels during the next 100 years. 3. Future chlorine growth has several sources. o In our "standard" evaluation^ of the impact of the Protocol, chlorine-containing chemicals not covered by the Protocol account for about 40 percent of the projected growth in stratospheric chlorine levels by 2075 (assuming methyl chloroform use grows as projected by some analysts). o Emissions from non-participant nations are projected to account for about 15 percent of the chlorine growth in the standard protocol scenario. o About 45 percent of projected chlorine growth in the standard Protocol scenario stems from allowed use of controlled compounds under that agreement. o For the scenarios in which methyl chloroform grows, it accounts for over 80 percent of the growth in chlorine levels associated with substances not covered by the Protocol. If its emissions do not grow from current levels, methyl chloroform's contribution would be much lower. 4. The projected levels of chlorine under the Montreal Protocol are influenced by the extent to which the use of partially-halogenated compounds increases as they substitute for the foregone CFCs covered by the Protocol. o Under worst case assumptions -- HCFC-22 (or other compounds such as HCFC-141b, -142b, or 123)2 substitute one-for-two for all the CFC-11 and CFC-12 foregone -- chlorine concentrations could increase by about an additional 1.0 ppbv by 2100 due to the increased use of these substitutes. •*- Our standard evaluation of the Protocol includes: 100 percent U.S. participation; 94 percent participation among other developed nations; 65 percent participation among developing nations; reduced growth in compound use among non-participants; no growth in compound use after 2050. 2 "HCFC" stands for "hydrochlorofluorocarbon," i.e., chlorofuorocarbon with a hydrogen atom. The hydrogen atom reduces the amount of chlorine transported to the stratosphere by increasing the oxidation rate in the lower atmosphere. ------- 3- o Under more realistic substitution assumptions of one-to-five for foregone CFC-11 and CFC-12, chlorine levels would be increased by about an additional 0.4 ppbv by 2100, an amount which is about 10 percent of the increase associated with the continued use of the fully-halogenated compounds covered under the Protocol. 5. Bromine levels will grow under the Montreal Protocol. o Current abundances are on the order of 1 pptv for Halon 1211 and Halon 1301. o By 2075 Halon 1211 is projected to grow to about 6 pptv, and Halon 1301 is projected to grow to nearly 13 pptv. 6. Additional reductions of the fully-halogenated compounds would reduce future chlorine and bromine levels substantially. o The reductions in chlorine levels will depend on the speed and magnitude of the emissions reductions. The difference between peak chlorine levels between a 100 percent phaseout by 1990 and a 95 percent phaseout by 1998 (with 100 percent participation and a freeze on methyl chloroform emissions) would be 0.8 ppbv. The slower and less stringent phasedown would result in chlorine levels in excess of the peak level from the faster, more stringent phasedown for over 50 years. o To stabilize chlorine abundances at current levels would require a 100 percent phaseout of the fully-halogenated compounds with 100 percent participation globally, at least a freeze on methyl chloroform use, and substitution of partially-halogenated compounds at relatively conservative rates. These relatively conservative rates of substitution would nonetheless allow HCFC- 22-like compounds to grow at nearly 4.0 percent per year, to nearly 80 times current HCFC-22 use levels by 2100. There would be a trade off between the ability to use increasing amounts of partially-halogenated substitutes and methyl chloroform. o To stabilize bromine levels requires about a 100 percent phaseout of Halon 1301, and 90 to 100 percent phaseout of Halon 1211, with 100 percent participation. ------- -4- 1. INTRODUCTION The recent Summary of the Ozone Trends Panel Report suggests that current atmospheric models may be underpredicting the amount of depletion for a given increase in atmospheric chlorine. The ability of models to project future depletion has been called into question. This analysis does not seek to address this problem -- that is, it does not focus on determining how the models should be modified to better depict the quantitative relationship among atmospheric levels of chlorine and bromine, and stratospheric ozone. Instead, the goals of this report are to: 1. assess how atmospheric levels of chlorine and bromine will change over time under the Montreal Protocol; 2. assess the emissions reductions necessary to stabilize the abundances of chlorine and bromine; 3. assess the relative contribution of different compounds to future increases in atmospheric levels of chlorine and bromine; 4. assess the potential contribution of partially-halogenated compounds such as HCFC-22, in contributing to future increases in chlorine levels; and 5. assess how atmospheric levels of chlorine and bromine may change with different coverage and stringency requirements in the Montreal Protocol. The merit of examining the potential for future ozone depletion by examining future levels of chlorine and bromine stems from the fact that chlorine and bromine abundances are currently thought to be the primary determinants of the risk of ozone depletion. Consequently, information about the abundances of chlorine and bromine can be of use to the decision making process without making final and certain conclusions about the quantitative relationship between their abundances and ozone depletion. Of course, to the extent that other chemicals, for example, NOX from high speed airplanes, or ------- -5- climate-induced shifts in atmospheric dynamics threaten stratospheric ozone, chlorine and bromine are inadequate measures of the potential risk of ozone depletion.^ 1.1 The Concept and Meaning of Stabilization The concept of stabilizing current chlorine and bromine levels as a means of preventing additional ozone depletion, or the risk of depletion, has received widespread attention. In particular, public references are frequently made to an 85 percent reduction in CFC-12 which is required in order to stabilize the chlorine contribution from that compound. While stabilizing chlorine and bromine from all chemical sources should stabilize the risk of further ozone depletions in the absence of other chemical or dynamical changes (i.e., assuming all other factors remain unchanged), emphasis must be placed on the inclusion of all industrial sources of these ozone-depleting chemicals. As is shown below, the potential chlorine contributions from non-regulated compounds (e.g., methyl chloroform, HCFC-22) must be considered in order to achieve the goal of stabilizing chlorine and bromine levels. The risk of additional ozone depletion is a function of increases in the levels of chlorine and bromine from regulated and non- regulated compounds alike. Thus, while an 85 percent reduction is sufficient to stabilize chlorine levels from one compound (i.e., CFC-12), it is not •* One reviewer also noted that the chlorine and bromine values estimated using the algorithm used in this analysis cannot be a perfect measure of ozone depletion risk because the algorithm is based on results of 1-D models in which the downward and poleward transport of chlorine (and bromine) are ignored. To the extent that some compounds contribute relatively more chlorine (or bromine) to latitudes and altitudes of high ozone, simple chlorine (and bromine) estimates will not reflect precisely the relative or absolute ozone depletion potential of different compounds. Investigations are currently under way to evaluate the implications of the simplifying assumptions used in this analysis for estimates of the relative risks associated with the contributions of chlorine from each of the compounds. ------- -6- sufficient for stabilizing total chlorine levels if the production and use of non-regulated chlorine-contributing compounds are considered. One other caveat is needed with regard to stabilization. As suggested by the Summary of the Ozone Trends Panel Report, if the ozone layer has already begun to deplete at current atmospheric levels of chlorine and bromine, stabilizing the contribution of chlorine or bromine from various chemicals would not reverse past depletion. Furthermore, to the extent that global ozone depletion is occurring due to dilution from the Antarctic ozone hole, stabilizing chlorine at current levels would not completely prevent the occurrence of future depletion associated with continued dilution from the existing hole. At this time, only preliminary estimates have been made of the ultimate dilution that will be associated with the current hole. There may be some additional hemispheric or global depletion still to come from the current hole. Therefore, the global ozone layer may already be committed to a residual amount of depletion at current levels of chlorine and bromine which has not yet had time to occur. 1.2 Report Organization Section 2 of this analysis discusses the methods used to estimate chlorine and bromine levels. Section 3 focuses on assessing the chlorine and bromine levels associated with the Montreal Protocol and their dependency on various assumptions about participation, substitution, and emissions after 2050. This section also addresses the question of the effect of widespread substitution of HCFC-22 or other partially-halogenated compounds. Section 4 focuses on determining the level of controls that would be necessary to stabilize the abundance of chlorine and bromine. Section 5 examines the effects on chlorine of different reduction stringencies and timings. ------- -7- 2. METHODS Future chlorine (Clx) and bromine concentrations depend primarily on future CFC and halon emissions and their atmospheric fate. Scenarios of emissions are analyzed based on estimates of current and projected future use of chlorine and bromine containing compounds under various assumptions. Compounds examined include CFCs (CFC-11, 12, 22, 113, 114, and 115), methyl chloroform (CH3CC13), carbon tetrachloride (CC14), and halons (Halon 1211 and Halon 1301). A parameterized model (presented in Appendix A) is used to estimate chlorine and bromine concentrations for this wide range of emissions scenarios. While not considering all the factors that influence Clx and halon levels (e.g., the impact of ozone depletion on atmospheric lifetimes is omitted), the model provides a useful first order approximation (UNEP 1987) . Exhibit 1 shows a conceptual diagram of the model (interested readers should consult the appendix for details). 2.1 Emissions Scenarios In this analysis, the middle scenario of CFC and halon use and emissions reported in EPA (1988) is used as a baseline "No Controls" scenario. This scenario is based on updated 1986 and 1987 data. Appendix B shows the global emissions in this scenario and the other scenarios analyzed. The following factors are varied in the scenarios: rate of participation in the It is assumed in this analysis that natural sources of chlorine and bromine remain unchanged. The contribution from natural sources is therefore ignored in computing changes in Clx and bromine from current levels -* Halon 1211 includes not only chlorine but bromine as well; Halon 1301 includes bromine (but no chlorine) Bromine is believed to pose risks to stratospheric ozone (WHO 1986). Halon 2402, which is included in the Protocol, is not assessed due to lack of data. The contribution of compounds like HCFC-141b are included later in the analyses by assuming that such partially-halogenated chlorine-containing compounds have the atmospheric characteristics of HCFC-22. ------- Montreal Protocol; growth in compound use among the non-participants; growth in methyl chloroform use; and extent to which partially-halogenated compounds are substituted for foregone CFCs. These factors are discussed more fully below. In the baseline scenario the average annual growth rate in demand for products and services that would use CFCs, if they were available, is approximately 4.0 percent from 1986 to 2000, and 2.5 percent from 2000 to 2050, for an average rate of 2.8 percent from 1986 to 2050 (based on preliminary data, growth in the U.S. from 1985 to 1987 has averaged 11.3 percent per year, ITC 1988). It is assumed that production is constant following 2050.6 It should be noted that the conclusions of the analysis are not overly sensitive to the baseline emissions assumptions. The baseline scenario is merely a convenient case that is used as a basis for comparison with other cases. It is reasonable to consider the range of scenarios examined here as "what if" scenarios. For purposes of evaluating compliance with the Montreal Protocol, global use is divided into six regions: U.S.; USSR and Other East Bloc; Other Developed Nations (i.e., Europe, Japan, Australia and New Zealand); China and India; Developing Nations I (i.e., developing nations with relatively higher levels of per capita CFC use); and Developing Nations II (i.e., developing nations with relatively lower levels of per capita CFC use) (see EPA 1988, Chapter 4). Each region is simulated to participate in the Protocol to various extents: the U.S. is assumed to participate; the USSR and the Other Developed Nations are assumed to achieve 94 percent participation; and 6 This assumption of constant production after 2050 is relaxed below in some scenarios to evaluate its implications for Clx and halon levels. ------- -9- Developing Nations are assumed to achieve 65 percent participation (see EPA 1988 for a discussion of the participation assumptions).' Alternative participation assumptions are explored below. 2.2 The Effects of Chemical Lifetimes on Chlorine Contributions The emissions of the compounds are translated into Clx and halon levels using atmospheric lifetimes and conversion factors for each compound (see Exhibit 2). The lifetimes indicate how long the chlorine associated with the compounds will remain in the atmosphere. As shown in the exhibit, the lifetimes of the compounds vary from about 8 years (CH3CC13) to 380 years (CFC-115). For the compounds other than the halons, the conversion factors convert emissions in millions of kilograms into ppbv of Clx and adjust for the relative efficiencies of the various compounds in supplying ozone-depleting chlorine to the stratosphere. The conversion factors for the halons convert millions of kilograms of emissions into atmospheric abundances in pptv for each compound. Also used is a mixing time of 3.5 years to simulate the time needed for the emissions to rise into the stratosphere. Note that the chlorine contribution of Halon 1211 is not counted in the Clx levels reported below. Because halons are treated separately in the ' The basis for these participation estimates includes participation in the Protocol process to date and judgments about the current receptiveness of nations to the Protocol. Alternative judgments are possible, and are tested below. Of note is that the non-participants are assumed to experience reduced use of the compounds in response to the development (by the participants) of technologies that do not rely on ozone depleters (see EPA 1988, Appendix C). For the years following 2000, the non-participants in the USSR, East Bloc, and other developed nations are assumed to experience 37.5 percent of their baseline growth rate, or about 0.94 percent growth per year. In developing nations it is assumed that non-participants experience 50 percent of their baseline growth rate, or about 1.25 percent per year. ^ The lifetimes are "e-folding" lifetimes, meaning that after the period of one lifetime has elapsed, the remaining level in the atmosphere is 1/e or about 37 percent of the original value. See Appendix A for a description of the model used to compute atmospheric levels. ------- 10- Protocol and contribute primarily bromine, halon abundances are reported separately. To assess the extent to which emissions result in increases in Clx levels, the current Clx and halon levels associated with these compounds are required.9 As shown in Exhibit 3, the anthropogenic-related Clx levels estimated with the model (totalling about 2.7 ppbv across the compounds included in the model) are similar to those estimated by Connell and Wuebbles (1986) and reported by WMO (1986).10 Also shown are halon levels. Based on the estimated values of the compound lifetimes and conversion factors, the level of emissions that would maintain the Clx and halon abundances at their 1985 simulated values can be computed. At these estimated levels of emissions, the decline in Clx and halon levels due to natural atmospheric removal processes would be exactly balanced by additional emissions. Exhibit 3 shows the levels of emissions that are consistent with stabilizing the chlorine contribution from each compound. These emissions are much smaller than the estimated 1985 levels of global emissions (also shown in Exhibit 3) , indicating that reductions in emissions are required in order to stabilize the Clx and halon levels from individual compounds at their 1985 values. Total chlorine can also be stabilized by cutting back some compounds more and others less than is shown in Exhibit 3; in fact, it would make little sense to stabilize total chlorine by stabilizing each compound's individual contribution. The estimates of changes in Clx and halon levels reported below are computed using the 1985 values as base values. The background level of Clx from other sources is assumed to remain constant, and is consequently not considered in this analysis. The abundance of halons comes solely from human sources, although there are other sources of bromine in the atmosphere (see WMO 1986). 10 These estimates do not include the naturally occurring chlorine from CH3C1. ------- 11 The difference in the compounds' atmospheric lifetimes have important implications for the relative contributions that the compounds make to chlorine levels over time. For example, it has been estimated that CFC-11 and CFC-12 have approximately the same ozone-depleting potential on a mass basis. This implies that at constant and equal levels of emissions, each of the compounds would contribute the same amount of chlorine to the stratosphere once steady-state conditions were achieved. However, because the two compounds have different lifetimes, steady- state conditions are not achieved at the same rate for each. Additionally, because the lifetimes are very long for each compound and because atmospheric conditions are not near steady state given current levels of emissions, it will take many decades before steady state conditions are approached. Therefore, as shown in Exhibit 4, the contributions of chlorine from CFC-11 and CFC-12 would not be equal over the next 50 years from equal annual emissions of 300 million kilograms per year. The differences in contributions of chlorine between these two compounds is emphasized in Exhibit 5 which shows the contribution over time from a single year of emissions of 300 million kilograms. Initially, CFC-11 contributes significantly more chlorine. Because CFC-12 has a longer lifetime, its contribution declines more slowly over time, and after about 100 years its contribution exceeds the contribution from CFC-11. Exhibit 6 shows the contribution of each of the compounds relative to the CFC-11 contribution on a year-by-year basis. As expected, the relative contributions of CH3CC13 and HCFC-22 decline rapidly due to their short lifetimes. However, to the extent that one is concerned about near-term increases in Clx on the order of 1.0 2.0 ppbv, near-term increases in CH3CC13 emissions must be considered carefully. Although the compounds with longer lifetimes show increasing ------- 12- chlorine contributions over time relative to CFC-11, CH3CC13 emissions present near-term risks from near-term emissions. (Other short-lived compounds should similarly by examined.) Therefore, in evaluating ozone-depletion risks based on Clx contribution, one must make judgments about relative concern to be placed on the potential for near-term depletion. By changing the radiative properties of the atmosphere, CFC emissions also warm the Earth's surface. By limiting the use and emissions of the fully-halogenated CFCs, the Montreal Protocol is expected to reduce the contribution of these compounds to this "greenhouse effect" by about 80 percent by 2100. This estimate is based on the assumption that currently- anticipated control options are used to reduce CFC use and emissions. However, if the mix of CFC use among compounds shifts significantly, the resulting greenhouse impact could be significantly different because the compounds have different impacts on global warming. As shown in Exhibit 7, the relative greenhouse impacts of the various compounds differ over time for equal amounts of emissions, and the relative impacts of the compounds with the longer lifetimes are quite high. As allowed under the Montreal Protocol, the use of the various CFCs can be traded off at rates that are defined by estimates of their steady-state relative ozone-depleting potentials. For example, about 1.7 kilograms of CFC- 115 can be traded off for 1.0 kilograms of CFC-11. If this theoretically permissible tradeoff were to occur between all the controlled CFCs and CFC-115 (a highly unlikely event), the expected CFC contribution to the greenhouse effect would almost double as compared to the standard Protocol scenario by 2100. Recognizing that the framers of the Protocol were "conscious of the potential climate effects of [CFC] emissions," this analysis indicates that ------- 13- th e tradeoffs among compounds allowable under the Protocol could unintentionally worsen the greenhouse impacts of the CFCs. 3. EVALUATION OF THE MONTREAL PROTOCOL 3.1 Potential Future Clx Levels By agreeing to and implementing the Montreal Protocol, the nations of the world are altering the future trajectory of Clx levels. Exhibit 8 presents a graph of changes in Clx for three scenarios of emissions: No IT 1 *} Controls, L Protocol, z and a True Global Freeze. The No Controls scenario shows large increases in Clx by 2100. The Protocol (under standard participation and growth assumptions) and True Global Freeze scenarios show approximately the same Clx increases (about 6.7 to 7.6 ppbv by 2100). The True Global Freeze scenario assumes that the use of all the chlorine containing compounds (including HCFC-22 and methyl chloroform) is frozen at 1986 levels starting in 1990, and that 100 percent participation is achieved worldwide. An alternative formulation of the Protocol, in which methyl chloroform is also assumed to be frozen at 1986 levels, shows less of an increase in Clx over the long term. Note that even by 2100 the Clx values in the Protocol and True Global Freeze scenario have not stabilized. Despite having constant emissions for H As described above, the No Controls scenario assumes average annual growth in use of 2.8 percent from 1985 to 2050 and no growth thereafter. 12 The Montreal Protocol calls for a limit on the use of CFC-11, -12, 113, -114 and 115 at 1986 levels starting in 1989, a 20 percent reduction from 1986 levels in 1993, and a 50 percent reduction from 1986 levels in 1998. It also calls for a limit on halon use at 1986 levels starting in 1992. 13 The chlorine values are increases in Clx relative to current levels of about 2.7 ppbv. Total Clx levels in 2100 are simulated to be about 9.4 to 10.3 ppbv for these two scenarios. 1^ Methyl chloroform may be frozen due to international agreement to limit emissions or due to a lack of demand. At least one reviewer associated with a chemical manufacturer considered methyl chloroform growth to be unlikely ------- 14- about 100 years under the True Global Freeze scenario, the Clx levels continue to increase slowly. The compounds with the longest lifetimes (CFCs 11, 12, 113, 114, and 115; CC14) have yet to achieve a steady-state level by this time, whereas the compounds with short lifetimes (HCFC-22, CH3CC13) have achieved a steady-state level. Although an increase in Clx of about 6.7 ppbv is achieved for this scenario by 2100, the eventual steady-state increase (which will take hundreds of years to approach) is 9.9 ppbv, with CFC-11 and CFG-12 accounting for about 7.9 ppbv of the increase.15 Exhibits 9 to 12 show the simulated increases in Clx values over time, the percent of the increase in Clx associated with each compound, and the equilibrium increase in Clx over 1985 values associated with the final level of emissions simulated. As shown in Exhibit 9, CFCs 11, 12 and 113 account for most of the Clx increases over time in the No Controls scenario (over 70 percent). CH3CC13 is initially significant (see the year 2000), but declines over time in relative importance while the importance of CC14 increases. The other compounds (CFCs 114 and 115 and HCFC-22) have a negligible relative contribution. Exhibit 10 shows the contribution by compound for the Protocol scenario. In this scenario the importance of the controlled compounds decreases over time, while the relative importance of CH3CC13 increases significantly, and the importance of HCFC-22 increases only slightly. " 15 For readers familiar with ozone-depletion estimates from 1-D models, Appendix C shows several cases of projected depletion. These cases show various emission scenarios for ozone-depleting compounds as well as scenarios for methane, carbon dioxide, and nitrous oxide concentrations. These projections of ozone depletion based on a 1-D model now appear to be inconsistent with monitored changes in ozone, thereby calling into question the adequacy of these models for projecting future changes in ozone. ^ Although CC14 is not controlled directly, CC14 emissions are assumed to decline as the use of CFC-11 and CFC-12 declines because the primary source of CC14 emissions is during the production of these CFCs. ------- -15- Although CH3CC13 is relatively more important in the Protocol scenario as compared with the No Controls scenario, the actual Clx contribution from the compound is the same for the two cases; the increased relative importance of CH3CC13 in the Protocol scenario is due to reductions in the contributions of the other compounds. As shown in the exhibit, under the Protocol assumptions, the contribution of CH3CC13 to Clx levels (e.g., about 35 percent in 2075) could become more important than the contribution of CFC-11 or CFC-12 (about 25 percent each in 2075). Exhibit 11 shows the relative contribution from each compound for the True Global Freeze scenario (in this scenario the use of all the compounds is frozen). As shown in the exhibit, CFCs 11, 12, and 113 grow in importance due to their relatively long lifetimes. CH3CC13 and HCFC-22, with their short lifetimes, become relatively less important.17 The other CFCs (CFC-114 and CFC-115) make relatively little contribution despite their long lifetimes because of their small levels of emissions. Exhibit 12 shows the relative contribution across the compounds for the Protocol scenario with CH3CC13 frozen at 1986 levels starting in 1989. As expected, the relative contribution of CH3CC13 is reduced significantly. It should be emphasized that neither HCFC-22 nor CH3CC13 grow faster in the above analyses due to the Protocol restrictions on CFC-11, CFC-12, or CFC- 113. This assumption is relaxed below. 17 Of note is that a key factor that will influence the future chlorine contributions of the partially-halogenated compounds is the future level of the OH radical in the troposphere. The OH radical is primarily responsible for the oxidation of the partially-halogenated compounds in the troposphere, thereby keeping their lifetimes short and their chlorine contributions low. The OH radical is itself influenced by many factors, including methane (CH4) and carbon monoxide (CO) levels. If CH4 and CO increase beyond levels now contemplated, or if their effects on the OH radical are greater than now believed, then the lifetimes of the partially-halogenated compounds (such as CH3CC13) would increase and their contributions of chlorine to the stratosphere would also increase. ------- -16- 3.2 Impact of Participation Assumptions The importance of the international participation assumptions in the Protocol Clx estimates is assessed by evaluating alternative sets of participation assumptions, listed in Exhibit 13. In addition to the standard assumption of 94 percent participation among non-U.S. developed nations and 65 percent participation among developing nations, both higher (up to 100 percent) and lower (down to 60 percent for developed nations and down to 40 percent for developing nations) participation scenarios are examined. The results are displayed in Exhibit 14. As shown in Exhibit 14, even with 100 percent global participation (Participation Scenario D), the Protocol requirements do not maintain Clx levels at their 1985 values. Assuming that CH3CC13 does not grow (Scenario D'), Clx increases by nearly 4 ppbv by 2100 (with 100 percent participation) which is approximately 2 ppbv less than Scenario D. Exhibit 15 shows that CH3CC13 accounts for nearly 40 percent of the increase in Clx by 2100 under the Scenario D assumptions. The scenarios with lower participation rates show larger increases in Clx. 3.3 Impact of Substitution Assumptions In the previous sections it is assumed that as the Protocol requirements are implemented and CFC and halon use is reduced, demand for other ozone-depleting compounds is not affected. In fact, other ozone- depleting compounds (HCFC-22 and CH3CC13 for example) will be substituted for the controlled CFCs. These other compounds could, therefore, contribute to increasing levels of Clx over time. To evaluate the potential contributions of Clx from these substitute compounds, five scenarios were analyzed in which a range of assumptions about the quantity of substitutions was examined. Furthermore, it was assumed that ------- 17- th e substituted compounds have the same atmospheric characteristics as HCFC- 22, or about 1/20 the depletion potential of CFC-11.^ The five substitution scenarios are as follows: o 1:1 -- Add one kilogram of the chemical substitute for each kilogram of CFC-11 and CFC-12 reduced; o 1:2 -- Add one kilogram of the chemical substitute for each two kilograms of CFC-11 and CFC-12 reduced; o 1:5 -- Add one kilogram of the chemical substitute for each five kilograms of CFC-11 and CFC-12 reduced; o 1:10 -- Add one kilogram of the chemical substitute for each 10 kilograms of CFC-11 and CFC-12 reduced; and o 1:1*-- Add one kilogram of the chemical substitute for each kilogram of CFC-11, CFC-12, CFC-113, CFC-114 and CFC-115 reduced. Exhibit 16 displays the results of these five scenarios, along with the standard assumption of no substitution (i.e., the Protocol scenario). As shown in Exhibit 16, substitution results in increased Clx levels. The 1:1 and 1:1* substitutions, which must be considered as unrealistically high due to the numerous opportunities for reducing CFC use without using ozone-depleting compounds as substitutes, results in an increase in Clx of about 3 ppbv over the standard assumption by 2100. The 1:2 substitution assumption, a more realistic worst case, results in an increase on the order •^ Other partially-halogenated chlorine containing compounds under consideration as substitutes include: HCFC-142b; HCFC-123; HCFC-141b; and HCFC-124. Each of these compounds has an ozone depletion potential of the same magnitude as HCFC-22. In addition, compounds containing no chlorine are being considered as substitutes, such as HFC-134a. To the extent that any of the widely-used partially-halogenated substitutes have significantly different characteristics than HCFC-22, additional analyses may be required to assess their implications for chlorine levels. 19 EPA (1988) describes a series of control options for reducing CFC use. Major control options that do not include ozone-depleting chemicals include: product substitutes for many foam-blowing applications; non-chlorinated chemical substitutes in solvent applications; recycling of used CFCs in refrigeration and air conditioning applications; and HFC-134a as a chemical substitute in refrigeration and air conditioning applications. ------- 18- of 1.0 ppbv by 2100. The more likely scenarios of 1:5 and 1:10 indicate less of an increase in Clx, with 1:5 producing an increase of an additional 0.4 ppbv by 2100.20 3.4 Impact of Post-2050 Growth Assumptions The above analyses assumes that the use of all the analyzed compounds levels out in 2050. In fact, assuming that the world's population and economy continue to grow beyond 2050 may imply continued growth in the demand for products and services that would use these compounds if available. Exhibit 17 displays simulated Clx levels for the No Controls and Protocol cases under the standard assumption of no growth following 2050, and under an alternative assumption of continued 2.5 percent annual growth following 2050. In the Protocol Post-2050 Growth case, continued growth occurs among non- participants and for non-controlled compounds. As shown in the exhibit, continued growth results in substantially higher Clx levels. In particular, one sees in the exhibit that the modest extent of leveling out of Clx that occurs in the long run in the Protocol case is in fact driven by the assumption of no growth in demand following 2050. When this assumption is relaxed, it appears as though the Protocol would allow higher long term Clx increases. 3.5 Potential Future Halon Levels Exhibit 18 presents estimates of potential future halon levels for the No Controls and Protocol scenarios. Although Halon 1301 emissions are modeled to be less than the Halon 1211 emissions (see Appendix B), the Halon 1301 f\ r\ zu Analysis in EPA (1988) indicates that the potential for substitution of ozone-depleting compounds for CFC-11 and CFC-12 is relatively small, on the order of 1:5 or 1:10. Because HFC-134a (which may substitute for CFC-12) does not have any ozone-depleting chlorine, a 1:1 ratio of substitution with chlorine-bearing compounds is very unlikely even if there were no other control options and even if future use of substitutes were not moderated due to increased costs relative to currently-used CFCs. ------- -19- concentrations are higher due to the compound's longer atmospheric lifetime. The potential role of halons in ozone depletion remains somewhat uncertain. Based on analyses by Connell (1986) with a 1-D model, the following general rules of thumb describe the ozone-depleting potential of the compounds: o based on atmospheric concentrations, 20 pptv of Halon 1211 is as effective at depleting stratospheric ozone as is 40 pptv of Halon- 1301;21 and o at moderate levels of Clx abundance (e.g., on the order of 10 ppbv), 20 pptv of Halon 1211 is about as effective as 1 ppbv of Clx at depleting stratospheric ozone. Based on these rough rules of thumb, the combined halon concentrations in 2100 in the No Controls scenario shown in Exhibit 18 may result in about the same level of ozone depletion as 3 ppbv of Clx. This assessment is very rough, but is provided to put the impact of halons on ozone into context. Due to the long atmospheric lifetime of Halon 1301, the freeze in use required under the Protocol is not sufficient to stabilize its atmospheric concentration. The fact that Halon 1301 is simulated to be stored in fire extinguishing systems which will result in emissions for many years also contributes to the continued increase in atmospheric concentrations shown in Exhibit 18. Exhibit 18 also shows estimates for Halon 1211. Because Halon 1211 has a relatively short atmospheric lifetime, and because Halon 1211 fire extinguishers are simulated to have shorter lives, the abundance of Halon 1211 21 Although on a concentration basis (i.e., in terms of ppbv) Halon 1211 is more potent than Halon 1301 at depleting ozone, on a mass basis (i.e., in terms of millions of kilograms of emissions) the reverse is true. The increased potency of Halon 1301 relative to Halon 1211 on a mass basis is due to the compound's longer lifetime which results in substantially higher concentrations for equivalent levels of emissions. 22 The relationship between Clx and ozone depletion varies depending on the Clx abundance and the concentrations of other trace gases (C02, N20, and /-ill/. \ CH4). ------- -20- flattens out in response to the Protocol requirements. Despite these characteristics, the Protocol requirements do not reduce the abundance of Halon 1211 to its 1985 levels over the next 50 years. 4. REDUCTION SCENARIOS TO STABILIZE Clx AND HALON LEVELS 4.1 Identification of Necessary Reductions Scenarios more stringent than the Protocol would be needed to stabilize Clx and halon abundances at 1985 levels. Several scenarios were examined to evaluate what controls would be needed. First, the Protocol reduction of 50 percent (a freeze for halons) was replaced with a reduction of 90 percent, and the timing of the reduction was moved from 1998 (1992 for halons) to 1990. As shown in Exhibit 19, under the standard Protocol participation assumptions, this scenario results in over a 4 ppbv increase in Clx by 2100. If the global participation in the reduction is increased to 100 percent, the Clx increment is held to about 2 ppbv by 2100, and is no longer increasing at that time. If the reduction was increased to 100 percent (i.e., full phase out of the fully- halogenated CFCs by 1990) with 100 percent participation, the increment in the Clx level would be limited to about 1.5 ppbv and would be declining by 2100. As shown in Exhibit 20, CH3CC13 is the primary compound contributing to the increases in the Clx levels relative to the 1985 value in this 100 percent Reduction scenario. *-° Also shown in Exhibit 20 are negative contributions to Clx increases from several compounds. The negative values indicate that although overall Clx levels increased relative to 1985 values, the Clx associated with those compounds decreased. For example, in Exhibit 20 the contribution from CC14 is shown as negative. This occurs because the simulated emissions are less than the level necessary to keep the CC14 contribution to Clx constant at its 1985 level, and the change in Clx associated with CC14 is consequently negative. This negative change for Clx (associated with CC14) divided by the positive overall change in Clx across all the compounds results in a negative contribution for CC14 being reported in the exhibit. ------- -21 Because the investigations above indicate that CH3CC13 may become an important relative contributor to Clx levels in the future (and because some industrial reviewers indicated that they beleived that the demand for CH3CC13 may not grow), a scenario of freezing this compound at 1986 levels in 1990 was investigated. Exhibit 21 shows the simulated increases in Clx associated with the 100 percent reduction in the fully-halogenated CFCs along with the freeze in CH3CC13. The increase in Clx is limited to under 1.5 ppbv assuming participation similar to the participation used to model the Protocol. If 100 percent participation is assumed, Clx levels are simulated to decrease by 2100 by about 0.6 ppbv. By that time, the contribution of chlorine from all compounds is less than the loss rate from stratosphere. In this scenario, the Clx associated with all the compounds except CH3CC13 (which is frozen) and HCFC-22 (which is not controlled) is simulated to decline. Unlike the other scenarios examined, this scenario, which includes a freeze on CH3CC13 (but does not include potential HCFC substitutes), stabilizes or reduces Clx abundances. 4.2 Impact of Substitution and Post-2050 Growth.Assumptions on Stabilization The long term outlook for Clx levels is influenced by the substitution of ozone-depleting compounds for controlled compounds and by the assumption that baseline compound use does not grow after 2050. Exhibit 22 shows the implications of assuming that the baseline demand for products and services that would use CFCs continues to grow at 2.5 percent per year from 2050 to 2100.^ The top two lines show the case of a 100 percent reduction in fully- halogenated CFCs and a freeze on CH3CC13, assuming the participation rates 24- Under these baseline assumptions, compound use grows by 2.5 percent per year after 2050. As described above, non-participants' use of controlled substances is reduced relative to these baseline assumptions when use limits are simulated. ------- -22- used for the standard Protocol evaluation. In this case the assumption of continued growth after 2050 results in simulated increases in Clx levels of about 2.4 ppbv by 2100 instead of 1.5 ppbv. The bottom two lines on the exhibit show the case of 100 percent reduction in the fully-halogenated CFCs, a freeze on CH3CC13, with 100 percent global participation. In this case the assumption of continued growth in use after 2050 results in the Clx levels rebounding so that by 2100 the levels are increasing, although the levels remain below the 1985 simulated values. Exhibit 23 displays simulated levels of Clx assuming that one kilogram of a substitute compound is used for each two or five kilograms of CFC-11 and CFC-12 that are foregone. As above, it is assumed that the substitute has the atmospheric characteristics of HCFC-22 (i.e., about 1/20 the depleting potential of CFC-11). The substitutions result in modest increases in the simulated Clx values. In the 100 percent global participation scenario, the 1:5 substitution results in an increase in simulated Clx levels of about 0.4 ppbv by 2100 relative to the no-substitute scenario. Exhibit 24 displays the implications of having both continued growth after 2050 and the use of chlorine-bearing substitute compounds. As above, a substitute with the atmospheric characteristics of HCFC-22 is assumed for two levels of substitution. Also, growth after 2050 continues at 2.5 percent per year. As shown in the exhibit, the combined effect of substitution and continued growth could result in increased chlorine levels even under stringent restrictions. Exhibit 24 may present the restrictions most likely to be necessary to stabilize Clx at current levels: a phaseout of the fully- halogenated compounds; a freeze in CH3CC13 use at current levels; and conservative use (e.g., about 1:5 substitution) of partially-halogenated ------- -23- replacement compounds.-" of note is that even this conservative rate of substitution (1:5) allows for significant increases in the use of HCFC-22-like compounds in the future. The 1:5 substitution assumption allows for nearly 4.0 percent annual growth of these compounds through 2100, or nearly and 80- fold increase over current levels. 4.3 Potential Future Halon Levels Similarly large reductions in use are required to stabilize halon abundances. Exhibit 25 displays estimates of Halon 1301 for 90 percent and 100 percent reductions. Even with 100 percent reduction in use by 1990, levels are simulated to remain above current values through 2100. Of note, however, is that this analysis does not assume significant recovery of Halon 1301 in existing systems. If these amounts were substantially recovered (and not emitted) Halon 1301 levels could decline. Exhibit 26 displays similar estimates for Halon 1211. Because Halon 1211 has a relatively short atmospheric lifetime, its atmospheric levels respond quickly to reduced emissions. As in the analysis of Halon 1301, increased recovery activity is not presumed. 5. IMPLICATIONS OF A VIRTUAL PHASEOUT OF CFCs FOR CHLORINE LEVELS The previous sections have examined the potential future levels of stratospheric chlorine that may be associated with the Montreal Protocol and the emissions reductions required in 1990 in order to stabilize chlorine levels at current values. This section assesses the implications of virtual phaseouts of CFC compounds that could be achieved within the Protocol framework and time frame. Unlike the previous section which evaluated large reductions starting in 1990, this section builds upon the current Protocol 25 The conservative use of the substitutes could be achieved by: agreements to limit use; the use of efficacious containment technologies; and/or the use of non-chlorine-containing compounds and technologies as substitutes ------- -24- schedule of reductions. The implications of requiring deeper reductions in 1998 is examined, followed by an evaluation of the effects of speeding up or delaying the required reductions. 5.1 Virtual Phaseouts in 1998 The following factors were varied in examining the implications of virtual phaseouts: o Stringency of the phaseout: 90 percent; 95 percent; 97 percent; and 100 percent. o Participation: standard participation assumptions^" and 100 percent global participation. o Methyl chloroform growth: methyl chloroform use and emissions grow in the future and methyl chloroform use is frozen at 1986 levels either due to international agreement or due to a lack of demand. o Substitution: ozone-depleting substitutes for foregone CFCs were assumed to range from no substitutes to one kilogram for each two kilograms of CFC-11 and CFG-12 foregone. o Long Term Growth. Compound use was assumed to have no growth following 2050 and was assumed to have continued growth at 2.5 percent per year following 2050. While varying these factors, the basic structure of the phased Protocol reductions was maintained. The 50 percent reduction required in 1998 was replaced with the more stringent reductions of 90, 95, 97, and 100 percent. The special allowances for developing nations and nations with planned expansions of production were also maintained. Exhibit 27 displays the estimated chlorine values for the four stringency levels assuming standard (i.e., less than 100 percent) participation and growth in CH3CC13. As shown in the exhibit, even with these stringent phaseouts, chlorine levels may increase on the order of 4 ppbv to 5 ppbv by 2100. Exhibit 28 shows that 100 percent participation in such ^" Standard participation assumptions are: U.S participation; 94 percent participation among other developed nations including the USSR and East Bloc nations; and 65 percent participation among developing nations. ------- -25- phaseouts would reduce the size of the increases in chlorine by about 2 ppbv by 2100. Even with 100 percent participation, however, the chlorine levels increase from current values. Exhibit 29 displays the estimated chlorine levels for the case when CH3CC13 is assumed to be frozen at 1986 levels starting in 1989. When compared to Exhibit 28, this exhibit shows that the continued growth in CH3CC13 contributed to the continued increase in chlorine relative to current levels over the long term. By virtually phasing out the CFCs and freezing CH3CC13 at 1986 levels, chlorine increases are kept below 1 ppbv by 2100. These results, however, do not include two factors that may increase future chlorine levels. As discussed in the previous sections, ozone - depleting compounds may be substituted for foregone CFCs. Exhibit 30 shows that "one-for-two" substitution may increase the estimated chlorine levels 0 7 somewhat.z' Similarly, Exhibit 31 shows the implications of both substitution 9 Q and continued growth in compound use following 2050.^ Even with 100 percent global compliance, the assumptions of continued growth and "one-for-two" compound substitution combine to result in estimated chlorine increases by 2100 for the four stringency levels. Of interest is that a tradeoff between stringency and substitution exists. For example, Exhibit 32 shows that the 90 percent reduction with one- to-five substitution yields approximately the same chlorine increases as a 100 percent reduction with a one-to-three or one-to-2.5 substitution. The 27 As discussed in previous sections, the substitute is assumed to have the atmospheric characteristics of HCFC-22. Also, "one-for-two" substitution is considered to be an upper bound for likely future substitution. 28 Assuming 100 percent compliance, the continued growth after 2050 affects only the use of HCFC-22 (which is not controlled) and the level of substitutes used. Continued growth after 2050 results in larger amounts of substitutes being used after 2050. ------- -26- implication of this tradeoff is that increasing the stringency of the phaseout from 90 percent to 100 percent would allow the use of HCFC-22-like substitutes to be approximately doubled. In other words, by giving up about 125 million kilograms of CFCs 11, 12 and 113 annually, an additional 235 million kilograms of substitutes could be used in the year 2000 without increasing Clx levels. By the year 2050 an additional 870 million kilograms of substitutes could be used annually without increasing Clx levels. This analysis indicates that within the Protocol framework, increases in chlorine levels can be kept to relatively low levels if the following is achieved: almost 100 percent participation; no future growth in CH3CC13 emissions; low rate of substitution of other ozone-depleting compounds (i.e., 9 Q the HCFCs); and movement out of all fully-halogenated ozone-depleting compounds over the long term in order to prevent long term growth in demand. 5.2 Speeding up or Delaying the Phaseout The timing of the phaseout will influence the trajectory of chlorine levels over time. Delays will allow additional emissions to increase chlorine levels. The increased levels will persist over time, increasing the risk of ozone depletion. To assess the implications of changing the timing of the phaseout a 100 percent phaseout with 100 percent participation and a CH3CC13 freeze was examined starting in six different years: 1990; 1993; 1996; 1998; 2003; and 2008. The general Protocol framework was maintained. As shown in Exhibit 33, the estimated chlorine levels for the six cases vary significantly by 2015. The differences among the cases persist for decades. In fact, delaying a full 29 As discussed above, even the low rate of substitution allows for significant increases in the use of these substitutes. ------- -27- phaseout from 1998 to 2008 increases the maximum chlorine level by about 0.7 ppbv and delays the decline back to 1985 levels by about 70 years. Because the differences among the cases persist for many years, the differences in the cumulative amount of chlorine contributed over time is a useful measure for evaluating the implications of the alternative timings. Exhibit 34 shows the differences in the cumulative amount of chlorine increase estimated for 1985 to 2100, relative to a timing of 1998. As shown, moving the phaseout up to 1990 reduces the cumulative contribution by over 11.5 ppbv. Delaying the phaseout to 2008 increases the cumulative contribution by over about 12.5 ppbv. Over this range the chlorine response is approximately linear to changes in the timing of the phaseout. Of note is that the general magnitude of the effect of timing on the cumulative chlorine contribution is not overly sensitive to assumptions about CH3CC13 growth or participation. Increasing participation tends to increase the importance of the timing of the phaseout. 6. SUMMARY Very large increases in Clx and halon abundances would have been expected if the use and emissions of chlorine-containing compounds and halons had been allowed to increase without limit. The provisions of the Montreal Protocol will reduce the amount of the increase significantly, but will not keep the levels of Clx and halons in the stratosphere from increasing. Significant additional reductions in emissions are required to keep the levels from increasing, possibly including a complete phaseout of the fully- halogenated compounds and a freeze on methyl chloroform. The rate of substitution with partially-halogenated chlorine-containing compounds will also influence future chlorine levels. If substitution is limited to key uses, and if emissions are contained, the impact of these substitutes on ------- -28- future chlorine levels would be relatively small. The timing of a phaseout affects both the magnitude of the Clx increase and the time required for Clx levels to decline back to 1985 values. ------- EXHIBITS ------- EXHIBITS ------- -29- EXHIBIT 1 CONCEPTUAL DIAGRAM OF THE CONCENTRATION MODEL Stratosphere Tropopause •• •• • •• • Released Atomic Chlorine Stratospheric Concentrations of the Molecules Troposphere-Stratosphere Exchange • •• •« • Tropospheric Concentrations of the Molecules Troposphere Alternative Emissions Scenarios Earth's Surface The concentrations model is based on results from a one-dimensional model of the atmosphere. As a one-dimensional analysis, the analysis reflects vertical transport only; latitudinal and longitudinal dependent effects are not considered. The analysis begins with alternative emissions scenarios based on a variety of assumptions. The emissions are translated into tropospheric concentrations of the compounds. The tropospheric concentrations in any year are a function of additions (due to emissions) and losses (due to transport to the stratosphere). The transport to the stratosphere is modeled using an exponential time constant of 3.5 years. This implies that 3.5 years after an emission takes place, about 63 percent of it has reached the stratosphere. In the stratosphere the molecules are broken down by solar radiation and release chlorine. The stratospheric concentrations of the molecules are adjusted for the relative amounts of ozone-depleting chlorine atoms supplied to the stratosphere. ------- -30- EXHIBIT 2 COMPOUND LIFETIMES AND CONVERSION FACTORS Compound Lifetime3 Conversion Factorb CFC-11 CFC-12 CFC-113 CFC-114 CFC-115 HCFC-22 CH3CC13 CC14 Halon 1211 Halon 1301 76 138 91 185 380 22 8 67 12 100 .5 .8 .7 .0 .0 .0 .3 .1 .9 .9 years years years years years years years years years years 1 0 0 0 0 0 1 1 3 3 .363 .761 .945 .372 .102 .285 .466 .709 .31 .68 X X X X X X X X X X 10 10 10 10 10 10 10 10 10 10 -4 -4 -4 -4 -4 -4 -4 -4 -2 -2 The lifetimes indicate how long the chlorine associated with the compounds will remain in the atmosphere. The lifetimes are "e- folding" lifetimes, meaning that after the period of one lifetime has elapsed, the remaining level in the atmosphere is 1/e or about 37 percent of the original value. For the compounds other than the halons, the conversion factors convert millions of kilograms of emissions into ppbv of Clx, and adjust for the relative efficiencies of the various compounds in supplying ozone-depleting chlorine to the stratosphere. The conversion factors for halons convert millions of kilograms of emissions into atmospheric abundances in pptv for each compound.

The method is taken from Connell (1986) and is based on a simplified representation of the exponential decay of abundances of each compound. The rate of decay is defined by an estimate of each compound's lifetime. Of note is that the method recognizes that each of the compounds has slightly different "efficiencies" with which its chlorine can perturb stratospheric ozone. The greater a compound's efficiency, the larger the impact its chlorine will have on stratospheric ozone. For example, HCFC-22 dissociates (and consequently injects its chlorine) at a different altitude than does CFG-11. Therefore, its chlorine is less efficient at depleting stratospheric ozone. The estimates of chlorine abundances produced by this method adjust for these relative efficiencies so that the total change in chlorine abundances summed across the compounds is a consistent measure of the potential impact on stratospheric ozone. The estimates of changes in Clx from 1985 levels are driven by the following data: o Emissions: the emissions for each of the scenarios examined are presented in Appendix B. o Lifetimes: the "e-folding" lifetimes of each of the compounds is presented in Exhibit 1 of the main text. These lifetimes (taken from Connell, 1986) were evaluated from a series of 1-D model runs with total column ozone depletions of around 10 percent (Connell 1986, p.5). Lower levels of depletion would result in higher estimates of the lifetimes, and consequently higher estimates of Clx. This downward bias in the estimates of Clx exists for the Protocol scenario examined in the main text, and the scenarios in which Clx is stabilized. o Conversion Factors: the factors that convert emissions (in millions of kilograms) into abundances of Clx are presented in Exhibit 1 of the main text. These conversion factors reflect the number of chlorine atoms per molecule, the molecular weight of the molecule, the relative efficiency of the compound's chlorine at depleting ozone, ------- A-3 and a factor combining the column number density of the atmosphere, the surface area of the earth, and Avogadro's number (see Connell 1986, p.5). The values used to compute the conversion factors are shown in Exhibit A-l. As shown in the exhibit, the relative efficiencies for the compounds vary from 0.288 for CFG-115 to 1.20 for CC14. o Mixing time: the time constant for mixing a surface - released tracer completely in the atmosphere and stratosphere is estimated at 3.5 years. o Clx from Historical Emissions: the algorithm estimates changes in Clx from levels in 1985. The contribution of historical emissions to these changes was estimated by Connell (1986) and is presented in Exhibit A-2. As shown in the exhibit, the contribution is initially positive, reflecting the mixing in of emissions prior to 1985. Over the long term the contribution becomes negative, reflecting the decay of the atmospheric abundance associated with emissions prior to 1985. Given these values, the contribution of each compound to changes in Clx in year t relative to 1985 levels is computed as: Clx(t.j) - CF(j) * Z emissions(j) * e'(t'i)/L(J> * (l-e(t'i)/MT) where: Clx(t,j) - the change in Clx in year t (relative to 1985) associated with emissions of compound j; CF(j) - conversion factor for compound j; L(j) - atmospheric lifetime of compound j; MT - mixing time. To compute the total change in Clx in year t, the contributions from each of the compounds is summed, and added to the change in Clx associated with pre- 1985 emissions. This general method is also used for computing halon abundances. However, the halon abundances are of the entire molecules, and are not ------- A-4 adjusted for the number of bromine and/or chlorine atoms, or their relative efficiencies at perturbing stratospheric ozone. Also, the contributions of historical halon emissions to future changes in abundances from 1985 are assumed to be zero. ------- A-5 EXHIBIT A-L CONVERSION FACTOR COMPUTATION DATA Compound #Cl/Moleculea CFC- CFC- CFC- CFC- CFC- CFC- 11 12 22 113 114 115 CFC14 CH3CC13 3 2 1 3 2 1 4 3 Molecular Weight 137. 120. 86. 187, 170, 154, 153, 133, ,4 .9 .5 .4 .9 .5 .8 .4 Relative Efficiency 1, 0. 0, 1, 0. 0, 1, 1, .14 ,84 .45 .078 .58 .288 .20 .19 Conversion Factor5 1 0 0 0 0 0 1 1 .363x10 .761x10 .285x10 .945x10 .372x10 .102x10 .709x10 .466x10 -4 -4 -4 -4 -4 -4 -4 -4 a/ #Cl/Molecule - number of chlorine atoms per molecule. —/ For each compound, the conversion factor is computed as: 5.477xlO'3 * (#Cl/Molecule) / Molecular Weight * Relative Efficiency.

40.5 40.5 40.5 ------- APPENDIX C ------- APPENDIX C OZONE DEPLETION ESTIMATES ------- C-2 This appendix presents estimates of ozone depletion for several emission and trace gas scenarios. The model used to estimate ozone depletion is described in Connell (1986) and EPA (1987). In light of the recent findings of the Ozone Trends Panel (1988), ozone depletion estimates based on results from 1-D models are called into question. Consequently, the ozone depletion estimates presented here may be considerable underestimates of potential near term depletion. Exhibit C-l displays estimated ozone depletion for the following three scenarios: No Controls; Protocol; and True Global Freeze. The No Controls scenario assumes that compound use will grow at an annual average rate of 2.8 percent per year through 2050, followed by no growth. As shown in the exhibit, such unconstrained growth is expected to lead to significant depletion. The Protocol and True Global Freeze scenarios are estimated to result in much less depletion, although as is indicated in the exhibit by the arrows, the values for these cases may be underestimated. The Protocol scenario has the following participation assumptions: U.S. participation; 94 percent of other developed nations; and 65 percent of developing nations. The True Global Freeze scenario assumes that all chlorine-containing compounds are frozen in 1989 at their 1986 levels, and that 100 percent global participation is achieved. The ozone depletion estimates are influenced not only by emissions of chlorine-containing compounds, but also by the future concentrations of key greenhouse gases: carbon dioxide (C02); nitrous oxide (N20); and methane (CH4). Although the chlorine concentrations in the Protocol and True Global Freeze scenarios are increasing through 2100, the ozone depletion expected ------- C-3 from these scenarios is declining by 2100 due to increasing concentrations of these greenhouse gases, and their associated global warming. If the concentrations of these gases are lower than currently expected, either due to less than expected growth in emissions or due to international agreements to limit emissions in order to reduce future levels of greenhouse warming, then the expected amount of ozone depletion would be higher than the levels shown in Exhibit C-l. Exhibit C-2 shows estimates of ozone depletion with alternative assumptions about future concentrations of the greenhouse gases. The Low Trace Gas Scenario assumes that concentrations grow more slowly than currently expected. The 2"C Scenario assumes that the greenhouse gas concentrations will be controlled sufficiently so that equilibrium global warming is limited to 2°C by 2075. As shown in the exhibit, the alternative trace gas assumptions have a significant influence on the estimates of ozone depletion over the long term. ------- C-4 EXHIBIT C-l SIMtTLATED GLOBAL AVERAGE TOTAL COLUMN OZONE DEPLETION: NO CONTROLS; PROTOCOL; AND TRUE GLOBAL FREEZE True Global Freeze -10.0 -20.0 - •a •§ 3 -50.0 -30.0 - -40.0 - 1985 2005 2025 2045 2065 2085 Assumptions: No Controls: Compound use grows at an average annual rate of 2.8 percent from 1985 to 2050, with no growth thereafter. Protocol: U.S. participation; 94 percent participation in other developed nations; 65 percent participation in developing nations. Use of compounds not covered by the Protocol grows at the rates in the No Controls scenario. Growth rates among non-participants are reduced to 37.5 percent (developed nations) and 50 percent (developing nations) of their baseline values. True Global Freeze: The use of all chlorine-containing compounds is frozen at 1986 levels starting in 1990, and 100 percent participation is achieved worldwide. Other Trace Gases: CH4 grows at 0.017 ppm/year; N20 grows at 0.2 percent/year; C02 grows at the 50th percentile rate reported by the NAS (about 0.6 percent/year). Arrows indicate that ozone depletion estimates may be underestimated. ------- C-5 EXHIBIT C-2 SIMULATED GLOBAL AVERAGE TOTAL COLUMN OZONE DEPLETION: PROTOCOL SCENARIO WITH ALTERNATIVE TRACE GAS ASSUMPTIONS •7.0 1965 2005 2025 2045 2065 2085 Assumptions: Protocol: U.S. participation; 94 percent participation in other developed nations; 65 percent participation in developing nations.

Growth rates among non-participants are reduced to 37.5 percent (developed nations) and 50 percent (developing nations) of their baseline values. Compound use assumed constant after 2050. Other Trace Gases: o Base Scenario: CH4 grows at 0.017 ppm/year; N20 grows at 0.2 percent/year; C02 grows at the 50th percentile rate reported by the NAS (about 0.6 percent/year). o Low Scenario: CH4 grows at 0.01275 ppm/year (75 percent of the base scenario value); N20 grows at 0.15 percent/year; C02 grows at the 25th percentile rate reported by NAS (about 0.4 percent/year). o 2°C Wanning Limited: Assuming a 3°C climate sensitivity to doubled C02, trace gas growth is limited so that projected equilibrium warming equals 2°C by 2075. Average rates of growth from 1985 to 2075 are: CH4: 0.24 percent/year; N20: 0.06 percent/year; C02: 0.15 percent/year. Arrows indicate that ozone depletion estimates may be underestimated. ------- |
