"The United States is reducing its greenhouse gas emissions far too slowly to help avert the worst effects of global warming. But what would happen if the country adopted seven of the most ambitious climate policies already in place around the world?"

"U.S. greenhouse gas emissions are currently projected to stay fairly flat. Reducing them faster would require major advances in clean technology or big shifts in policy. Or both.

The U.S. made a pledge under the Paris climate agreement to cut emissions by 2025. It also laid out broad goals for 2050."
