EPA: FOSSIL FUEL USE CONTRIBUTES TO GREENHOUSE GAS RISE

Renewable Fuel News, March, 2004 by Cole, Carol

Total U.S. greenhouse gas (GHG) emissions have risen by 13% from 1990 to 2002, according to EPA's latest assessment. The primary GHG emitted by human activities was CO2, representing approximately 83.8% of total GHG emissions.

The largest source of CO2 and of overall greenhouse gas emissions was fossil fuel combustion. Mobile source fossil fuel combustion was one of two major contributors of N^sub 2^O emissions.

Emissions from fuel combustion resumed a modest growth in 2002, slightly less than the average annual growth rate since 1990, according to the draft report U.S. Greenhouse Gas Emissions and Sinks: 1990-2002.
