In 2020, carbon dioxide emissions from Pacific Northwest power plants that burn coal and natural gas totaled 45.64 million metric tons, the lowest in at least 25 years and a roughly 20-percent decline from emissions in 2019 (2020 is the latest year for which emissions data is available). The data reflects emissions from electricity generation at power plants and does not account for ‘upstream’ emissions from, for example, coal mining and gas production.
