Monthly U.S. energy-related carbon dioxide (CO2) emissions fell to 307 million metric tons (MMmt) in April 2020, the lowest value in the U.S. Energy Information Administration’s (EIA) monthly series for CO2 emissions, which dates back to 1973. Travel restrictions and other measures to mitigate the spread of coronavirus in April resulted in sudden and significant changes in energy consumption, resulting in lower energy-related emissions.
