Background

MN350 is a left-of-center climate-issue advocacy group; it has a sister advocacy and social welfare nonprofit called MN350 Action. It is a state chapter of a national climate issue advocacy group called 350.org. The term “350” derives from “350 ppm,” which refers to the claim that 350 parts per million is a “‘safe’ level of carbon dioxide” in the atmosphere.  ^{1  2}

The group is concerned with rising sea levels, loss of farmland, an increase in mosquito-borne diseases, and the potential for extreme weather events. The group is seeks to end the use of fuel energy resources to limit climate change.  ^{1  3}

The group claims that part of its mission is “building a powerful mass movement to end systems of oppression and realize our vision of climate justice.”  ⁴

MN350 is a member of the Clean Heat Coalition, which it describes as “a multi-racial, statewide coalition of partners” that advocates for “Clean, Midwest-made energy.”  ⁵
