Since taking office, President Donald Trump has significantly weakened federal policy by pulling out of the Paris climate agreement, working to repeal nearly 100 environmental protection laws, and continuously advocating for the use of coal.
But states are fighting back.
Since 2017, nearly half of state governors and Puerto Rico have signed legislation that will uphold Paris agreement emission reductions.
But it’s not clear if it’s enough. According to 2016 data, these 25 members account for only about 42% of US carbon emissions.
Leah Stokes, an assistant professor of political science at the University of California, said that while state efforts are making an impact, action at the federal level will be required if we want to cut carbon emissions in half and avoid catastrophic warming in the next decade.
