Despite continued rapid growth in solar and wind power, emissions levels stayed relatively flat last year because demand for electricity surged nationwide, which led to a spike in the amount of natural gas burned by power plants. The fact that emissions didn't decline much means the United States is even further off-track from hitting President Biden's goal of slashing greenhouse gases 50 percent below 2005 levels by 2030.
Since 2005, United States emissions have fallen roughly 20 percent, a significant drop at a time when the economy has also expanded. But to meet its climate goals, U.S. emissions would need to decline nearly 10 times as fast each year as they've fallen over the past decade.
It's notable that we've now seen two years in a row where the U.S. economy grew but emissions went down, said Ben King, an associate director at the Rhodium Group. But it's far from enough to achieve our climate targets.
