Total US emissions have increased by 5.9% from 1990 to 2013.

The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. Additionally, relatively cool winter conditions led to an increase in fuels for the residential and commercial sectors for heating. The transportation sector was the second largest sector source, at 27%. Transportation emissions increased as a result of a small increase in vehicle miles traveled (VMT) and fuel use across on-road transportation modes…
