Carbon dioxide emissions from S energy consumption will remain near current levels through 2050, according to projections in EIA’s Annual Energy Outlook 2019 . The AEO2019 Reference case, which reflects no changes to current laws and regulations and extends current trends in technology, projects that US energy-related CO 2 emissions will be 5,019 million metric tons in 2050—4% below their 2018 value—as emissions associated with coal and petroleum consumption fall and emissions from natural gas consumption rise. USenergy-related carbon dioxide emissions and fossil fuel energy consumption. Source: US Energy Information Administration, Monthly Energy Review, Annual Energy Outlook 2019 Reference case Energy-related CO 2 emissions generally follow energy consumption trends. In the United States, emissions associated with the consumption of petroleum fuels—motor gasoline, distillate, jet fuel, and more—have consistently made up the largest portion of CO 2 emissions. In 2018, the transportation sector’s consumption accounted for 78% of US CO […]
