Carbon dioxide emissions in the United States from the production and consumption of energy have been on the decline since about 2005, after generally being on the rise ever since our country was first founded.
The decline in emissions between 2012 and 2011 was 3.8 percent, which, according to the Energy Information Administration (EIA) was the largest decline in a non-recession year since 1990 and the first time that carbon dioxide (CO2) emissions fell while the per capita economic output increased by more than 2 percent. In other words, we are producingmore while emitting less carbon dioxide.
