Electrify Everything

350Marin is proud to be a part of the Clean Energy movement happening around the country and in local groups of 350 Bay Area. Our campaign is focused on getting to that 100% carbon-neutrality goal for all of California even faster than the 2045 date that the Governor Brown set in his Executive Order.

Financing a Green Climate Future

Divestment is the opposite of investment–it simply means getting rid of stocks, bonds or investment funds that are unethical or morally objectionable, particularly fossil fuel investments which are a risk for investors and for the planet.

Advocating for Climate Leadership

Building our political power through local education and advocacy in order to foster climate leadership and action in the County of Marin.
