New Hampshire

New Hampshire’s greenhouse gas emissions have decreased 5% from 1990-2022, with transportation as the highest-emitting sector. While two thirds of the state’s electricity is powered by nuclear energy, New Hampshire still hosts the last two coal power plants in New England, though they’re scheduled to shut down by 2028.
