The United States remain one of the largest emitters of CO2, with 17.3 tonnes per capita, despite a decline due to the recession in 2008-2009, high oil prices and an increased share of natural gas. Natural gas consumption increased globally by 2.2% In the European Union, CO 2 emissions dropped by 3% to 7.5 tonnes per capita.
The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. During 2012, particularly in the spring and early summer, low natural gas prices led to competition between natural gas- and coal-fired electric power generators.

Factors influencing the decrease included: In 2011, transportation-related carbon dioxide emissions fell primarily due to higher fuel costs, improvements in fuel efficiency, and a reduction in miles traveled. This would tend to put upward pressure on electricity demand and related emissions.
