U.S. energy-related CO2 emissions rose in 2018 for the first year since 2014

Total U.S. energy-related carbon dioxide (CO2) emissions in 2018 rose to 5.27 billion metric tons, 2.7% more than its 2017 level. The primary reasons for the increase were higher natural gas-related emissions resulting from more extreme summer and winter weather and growth in transportation-related petroleum emissions, linked to a strong economy. U.S. energy-related CO2 emissions declined in 6 of the past 10 years and were 12% lower in 2018 than in 2005, according to a data series published in the U.S. Energy Information Administration’s (EIA) Monthly Energy Review.
