The Biden administrations Inflation Reduction Act helps regulate carbon pollution from power plants and cars and trucks. Progressive states such as California, New York, and Illinois responded by passing tougher climate laws of their own. To reach the Paris Agreement goal of cutting carbon emissions in half at the end of this decade, where will America’s remaining greenhouse gas emissions come from? What should climate policy focus on next?

Robinson Meyer from HeatMap writes that “We’re back to emitting like it’s 1991 – even with a bigger economy.”

The first time since the beginning of the pandemic both America’s economy and carbon emissions moved in the right direction. America’s greenhouse gas pollution from energy and industrial activities fell by 1.9% in 2023 compared to the year before. It’s the first time in this decade that the U.S. has hit the mark of growing its economy and cutting its climate pollution at the same time.
