The Florida Department of Environmental Protection report, Preliminary Inventory
of Florida Greenhouse Gas Emissions: 1990-2004, provides estimates for Florida's
greenhouse gases (GHG) by sector for 1990 through 2004.1

In 1990, Florida emitted GHGs in the amount of 209.5 million metric tons carbon
dioxide equivalent (MMTC02E). In 2004, GHG emissions from Florida increased by 38
percent of 1990 levels to 289.1 MMTC02E.

Emissions from the energy sector, which constitutes the majority (90 percent) of
gross GHG emissions, increased by 36 percent between 1990 and 2004. This was
mostly a result of the growth of C02 from fossil fuel combustion which is comprised
largely of the utility and transportation sub-sectors (49 and 43 percent, respectively).

The emissions resulting from land-use change and forestry were not included in
the state inventory report due to limited data availability.

1 Historical GHG emission estimates (1990 through 2004) were estimated using a set of
generally-accepted principles and guidelines for state greenhouse gas emission estimates, with
adjustments to provide Florida-specific data and inputs when it was possible to do so. The
inventory was developed using the U.S. Environmental Protection Agency's (EPA's) State
Inventory Tool.

An asterisk (*) indicates emissions of the gas from this sector were zero, insignificant, or not reported.

All emissions are reported in million metric tons of carbon equivalent (MMTC02E).

-------
Over the 15-year period, carbon dioxide (C02) emissions accounted for over 90
% of Florida's GHG emissions and have increased each year since 1990. The energy
sector was the main contributor of C02 emissions (over 97 % in 2004). Methane (CH4)
was the second largest contributor to Florida's GHG emissions and has remained
relatively constant between 1990 and 2004. Methane emissions came mostly from
enteric fermentation within the agriculture sector (22 % in 2004) and landfills within the
waste management sector (55 % in 2004). The third largest contributor to Florida's GHG
emissions, Nitrous Oxide (N20), also remained relatively constant throughout the 15-
year period. Significant contributors for this gas were mobile combustion emissions and
agricultural soil management emissions (each representing 35 % in 2004).
Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)
contributed the smallest share of total GHG emissions for Florida but between 1990 and
2004 increased by over 400 % of 1990 levels. This increase in HFCs, PFCs and SF6
emissions within the industrial processes sector is largely due to the replacement of
ozone-depleting substances (CFCs) with HFCs, which have high global warming
potentials.

Gross per capita emissions from Florida were 16 MTC02E in 1990 and increased
to 17 MTC02E in 2004. Per capita emissions were less than the gross national per
capita average of 25 MTC02E in both years.
