The U.S. Environmental Protection Agency (EP A) has released its latest report on nationwide greenhouse gas (GHG ) emissions. Presenting data from 1990 to 2010, the report calculates carbon dioxide emissions removed from the atmosphere by “sinks,” an example of which is the uptake of carbon by forests, vegetation and soils.  

Each year the report is submitted to the Secretariat of the United Nations Framework Convention on Climate Change. According to EP A, the most important new findings are that (i) GHG emissions in 2010 totaled 6,821.8 million metric tons of carbon dioxide; (ii) U.S. emissions rose by 3.2 percent from 2009 to 2010, due to an increase in economic output resulting in an increase in energy consumption across all sectors and much warmer summer conditions resulting in an increase in electricity demand for air conditioning; and (iii) U.S. GHG emissions have increased since 1990 by 10.5 percent.
