After a 2.7% increase in US energy-related carbon dioxide (CO2) emissions in 2018, EIA’s July “Short-Term Energy Outlook” (STEO) forecasts a 2.2% decrease in CO2 emissions for 2019. Nearly all of the forecast decrease is due to fewer emissions from coal consumption. Forecast natural gas CO2 emissions increase and petroleum CO2 emissions remain virtually unchanged.

Based on data in EIA’s “Monthly Energy Review,” energy-related CO2 emissions in the first three months of 2019 were largely similar to those in the first three months of 2018. In the first quarter of 2019, EIA estimates that US energy-related emissions totaled 1,367 million metric tons (MMmt), which is nearly equal to those in the first quarter of 2018.

The first quarter of the year is typically the period with the highest CO2 emissions in the United States, and therefore, heavily influences the overall annual trend. In the past 30 years, only 6 years have had an overall annual emissions trend that was different than that of the year’s first quarter. If EIA’s emissions forecast is realized, 2019 will be the seventh such year, with overall emissions decreasing from 2018 values despite a first-quarter increase.

For the remainder of the year, EIA expects that relatively mild forecast temperatures will keep energy demand and resulting energy-related CO2 emissions below last year’s levels. EIA’s expectations for weather are largely based on forecasts produced by the National Oceanic and Atmospheric Administration’s Climate Prediction Center.

EIA forecasts that CO2 emissions from coal will decrease by 169 MMmt in 2019, the largest decrease in CO2 emissions from coal since 2015. Conversely, EIA projects CO2 emissions from natural gas to increase by 53 MMmt. Both changes are largely due to forecast changes in the electricity generation mix as natural gas continues to grow as the most prevalent electricity generation fuel.
