Maine has met the first of its four climate goals by reducing gross greenhouse gas emissions by 30% from 1990 levels, well ahead of its 10% goal by 2020, but it has a long way to go to meet a 45% cut by 2030 over the next six years. Unlike the emissions reduction goals, carbon neutrality can be improved from both ends: cutting greenhouse gas emissions, which trap the sun’s heat in the Earth’s atmosphere and cause warming, and increasing the sinks that absorb atmospheric carbon and store it someplace, like a tree’s roots.
