350 Tacoma is a left-of-center environmentalist group located in Tacoma, Washington. The group aims to eliminate conventional energy sources in Washington state, and supports the Green New Deal, a proposal to expand government control of the economy on environmentalist pretexts. 
350 Tacoma campaigns to generate public outrage against companies that use conventional energy sources, works with communities to create jobs using alternative energy sources, and pressures governments to enact regulations cracking down on conventional energy. 
350 Tacoma vehemently opposes Puget Sound Energy’s construction of a Liquefied Natural Gas (LNG) facility on Tacoma’s Tideflats, arguing that LNG emits too much carbon, and violates the sovereignty of the local Puyallup Tribe.  Puget Sound Energy argues that LNG will benefit the environment and that natural gas will benefit customers in the area during winters. 
350 Tacoma is a 501(c)(3) non-profit organization, though no financial information is publicly available because the group receives too little revenue to file a full Form 990 tax return.
