   Jan 19, 2024 · In 2021, the US emitted 6,340 million metric tons of greenhouse gas emissions in carbon dioxide (CO2) equivalent metric tons. [1] That’s 2.3% lower than measured in 1990, and 15.6% lower than 2007, when the US hit its recorded peak of 7,511 million metric tons of greenhouse gas emissions.

   Why are US coal emissions falling a lot?

   • In comparison, between 2005 and 2019, U.S. emissions fell nearly 1 percent annually, on average, according to the Environmental Protection Agency. The uptick occurred largely due to a 17 percent jump in coal-fired power generation, the first annual increase in coal generation since 2014, and a rapid resurgence of road transportation.

   Why is it important to know where methane sources come from?

   • “There’s an urgency in understanding where the sources are coming from so that we can be better prepared to mitigate methane emissions where there are opportunities to do so,” said research scientist Ben Poulter at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
