The coalition now numbers 14 states and Puerto Rico — North Carolina joined last week — and includes several states with Republican governors.
Climate Alliance, as the group is calling itself, released a report last week showing that through expanding solar power, wind energy, incentives for electric cars, building efficiency standards and other local efforts, the participating states cut greenhouse gas emissions 15 percent between 2005 and 2015, compared with 10 percent for the rest of the U.S.
Meanwhile, economic output in those states grew by 14 percent from 2005 to 2015, compared with 12 percent for the rest of the country.
Hurricane Harvey dumped 51.8 inches of rain on Texas, the all-time record for the continental U.S., and Hurricane Irma sustained 185 mph winds for 37 hours, also an all-time record.
It is important that other countries in the world perceive this, in order to prevent a global backslide.” David Victor, co-director of UC San Diego’s Laboratory on International Law and Regulation, said that although most of the states involved are Democratic, he thinks others may join, including possibly more conservative places like Iowa and Texas, which have a large wind industry, if their leaders frame the issue as supporting renewable energy rather than climate change, a more loaded political term.
