Concerns about climate change are driving a growing number of states, utilities, and corporations to set the goal of zeroing out power-sector carbon emissions. To date 17 states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity in the next couple of decades. Additionally, 46 U.S. utilities have pledged to go carbon free no later than 2050. Altogether, these goals cover about half of the U.S. population and economy.

The U.S. has a lot of work to do to draw down carbon emissions. But a new report shows that when it comes to the energy grid, things are actually in better shape than researchers thought it’d be by this point.

The analysis from the Department of Energy’s Lawrence Berkeley National Laboratory takes a look back at federal projections from the Energy Information Administration from 2005. The agency forecast that carbon pollution tied to electricity generation would increase 600 million metric tons between 2005 and 2020, a 25% increase from 2,400 million tons.
That’s not what happened, though. Instead, carbon emissions from the grid actually fell to 1,450 million metric tons in 2020. That’s a 40% reduction compared to 2005 and 52% below where the EIA thought grid-related emissions would be by now.
