The US Environmental Protection Agency (EPA) has published the draft annual US Greenhouse Gas Inventory. The major finding in this year’s draft report is that overall emissions during 2006 decreased by 1.5% (111.8 Tg CO2 equivalent) from the previous year. Total US greenhouse gas emissions in 2006 were 7,201.9 Tg CO2 Eq.
The primary factors contributing to the decrease, according to the EPA, were: (1) compared to 2005, 2006 had warmer winter conditions, which decreased consumption of heating fuels, as well as cooler summer conditions, which reduced demand for electricity; (2) restraint on fuel consumption caused by rising fuel prices, primarily in the transportation sector, and; (3) increased use of natural gas and renewables in the electric power sector.
Overall, emissions have grown by 14.1% from 1990 to 2006 while the US economy has grown by 59% over the same period. (…)
