"After an increase in 2018, energy-related CO2 emissions in the US are expected to decrease this year, and a drop in coal consumption is far and away the biggest reason for the change.
The estimates come from the US Energy Information Administration (EIA), which forecasts a 2.2% decrease in US energy-related CO2 emissions for 2019, after a 2.7% increase last year:
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.
The first three months of 2019 and 2018 were roughly equal in CO2 emissions — the first quarter of each year typically has the highest emissions. However, the EIA expects that mild temperatures will keep energy demand lower for the rest of the year."
