In 2020, carbon dioxide (CO2) emissions from the U.S. energy sector could be 11% lower than in 2019, according to U.S. Energy Information Administration (EIA) data through August and EIA estimates for September through December. According to values published in EIA’s December Short-Term Energy Outlook (STEO), EIA expects CO2 emissions in 2020 to fall by 19% for coal, by 13% for petroleum, and by 2% for natural gas. Many of this year’s changes in energy-related CO2 emissions are attributable to the economic and behavioral effects the COVID-19 pandemic has had on energy consumption.
