                              In 1998, the United States generated 220 million tons  of munici-
                              pal solid waste (MSW). The landfilling and combustion  of this
                              waste resulted in greenhouse gas (GHG) emissions of 65 million
                              metric tons of carbon equivalent (MMTCE). Today, a variety  of
                              software programs and models are available to help managers and
                              planners reduce emissions at state, local, business, and institu-
                              tional levels. These tools can enable  them to determine the
                              impact of their practices on climate change and the environment,
                              as well as strategies to reduce those  impacts.

                              The WAste Reduction Model (WARM) was developed by ICF Consulting for EPA's
                              Climate and Waste Program. The Cities for Climate Protection (CCP) Campaign
                              Greenhouse Gas Emission Software was produced by Torrie Smith Associates for
                              the International Council for Local Environmental Initiatives (ICLEI). The MSW
                              Decisions Support Tool (DST) was developed  by EPA's Office of Research and
                              Development and the Research Triangle Institute (RTI). Each tool  targets spe-
                              cific end-users to satisfy unique needs and constraints.

The WAste
Reduction Model
The WAste Reduction Model (WARM) is a
user-friendly software tool that enables
waste managers to compare GHG emissions
from business-as-usual waste management
practices with emissions from alternative
strategies. WARM covers 17 types of materi-
als and 5 waste management options: source
reduction, recycling, combustion, compost-
ing, and landfilling. WARM also accounts for
transportation distances to disposal and
recycling facilities, carbon sequestration, and
utility offsets that result from landfill gas
collection  and combustion.
WARM users input data on the amount of
waste handled by material type and man-
agement practice, and WARM instantly cal-
culates the associated emissions in metric
tons of carbon equivalent (MTCE) for base-

-------
line and alternative scenarios. The
difference between alternative emis-
sions and  baseline emissions repre-
sents the  benefits of changing your
waste management practices.
Available free on the Web and in
Microsoft ExcelŽ, this program is ideal
for waste planners to track and report
voluntary GHG emission reductions
from waste management practices and
to compare the climate  change
impacts of different approaches.

CCP  Software
The Cities  for Climate Protection (CCP)
Campaign  Greenhouse Gas Emission
Software is targeted for use by local
governments. This Windows-based tool
can analyze emissions and emissions
reductions on a community-wide basis
and for municipal operations alone.
The community-wide module looks at
residential, commercial, and industrial
buildings,  transportation activity,  and
community-generated waste. The
municipal  operations module looks at
municipal  buildings, fleets, and waste
from in-house operations. In addition
to computing greenhouse gas emis-
sions, the  CCP software  estimates
reductions in  criteria air pollutants,
changes in energy consumption, and
financial costs and  savings associated
with energy use reductions.
The software supports  quantification
of emissions  reductions from  waste
reduction, source reduction, energy
savings, and  fuel switching. Users
can employ the preformatted charts
and reports to develop cost-effective
action  plans to monitor progress on
reducing emissions.
CCP software subscriptions, which
include technical support, are
available  to governments that are
members  of ICLEI for a subsidized
price  of $240.  The full retail price
of the software in  the United
States is  $2,000.

MSW  Decision
Support  Tool
The MSW Decision Support Tool
(DST) is intended for use by solid
waste planners  at state and local
levels to analyze  and compare MSW
management strategies with respect
to cost, energy consumption, and
environmental releases to the air,
land,  and  water. As such, this tool
calculates projected emissions of
greenhouse gases, criteria air  pollu-
tants, and emissions of more than
30 air- and water-borne pollutants.
The MSW DST is  designed to model
emissions  associated with municipal
waste activities, including emissions
from source reduction, waste  collec-
tion and transportation, materials
recovery facilities, transfer stations,
compost facilities, combustion and
refuse-derived fuel facilities, and land-
fills. The MSW DST can be used  to per-
form complex analyses, such as deter-
mining the most cost-effective or
most energy-efficient waste manage-
ment strategy for  reaching specific
policy goals (e.g., how best to divert
40 percent of landfill waste by 2005).
This modeling tool  is available to
the public on a case-by-case basis.
The MSW DST studies vary in cost,
with simple analyses offered at no
charge, and complex analyses  gener-
ally starting at  $10,000. In addi-
tion, a supporting life cycle invento-
ry (LCI) database for North America
is planned for release in the fall of
2001. This comprehensive database
contains environmental emissions
and cost data on waste management
activities, materials  production,
equipment usage, transportation,
and energy production.

Benefits
Solid waste management practices can
reduce greenhouse gas emissions from
the waste sector, as well as reduce
upstream and downstream emissions.
Empowering waste managers and gov-
ernment planners with information on
the climate and other environmental
impacts of their current activities and
alternative practices enables them to
design the most effective strategies
for maximum  environmental, econom-
ic, and social benefits.

EPA's Climate and Waste Program increases
awareness of climate change and its link to
waste management in order to (1) make
greenhouse gas emissions a factor in waste
management decisions and (2) employ waste
management as a mitigation action for reduc-
ing greenhouse gas emissions. For additional

Program, see www.epa.gov/mswclimate.
