Maine’s Janet Mills was among a group of governors and national climate leaders in New York Thursday to announce a goal of installing 20 million heat pumps in U.S. homes by 2030. Mills is co-chair of the U.S. Climate Alliance, a coalition of almost exclusively Democrat-led states that formed in 2017 after then-President Donald Trump pulled the country out of the Paris Agreement, a global accord to combat climate change. Over the last six years, the alliance has encouraged policies that reduce carbon emissions and reliance on fossil fuels, but Thursday’s announcement was the group’s most ambitious yet.
