350 Action

What 350 Action does

350 Action is the 501(c)(4) electoral and political arm of 350.org, a global climate advocacy organization. Founded in 2013, it operates as a nonprofit dedicated to changing the politics of climate change in the United States through candidate endorsements, voter education, and grassroots mobilization. The organization endorses climate champion candidates at federal, state, and local levels; produces mayoral scorecards and voter guides evaluating candidates' climate policy commitments; and runs get-out-the-vote (GOTV) programs including phone banking, canvassing, and poll monitoring. Its 2025 'Our Cities, Our Roots' campaign extended this work into municipal mayoral elections across NYC, Detroit, New Orleans, Boston, and Seattle, with a notable success in the NYC Democratic primary where its top-ranked candidate Zohran Mamdani won.

The organization has a small core staff of 1-10 employees but leverages the broader 350.org network and coalition partnerships (including 165+ groups in the Protect the Results coalition) to generate large-scale volunteer mobilization—in one cycle it signed up 30,000+ canvassers and another cycle generated 364,000+ phone calls and 1,000+ poll monitors. It works in tandem with state-chapter affiliates such as 350 Mass Action and 350 New Hampshire Action. Products are entirely non-technological: scorecards, voter guides, candidate endorsements, and organizing campaigns distributed via the website, email, and social media.

Revenue is generated exclusively through charitable donations via the ActBlue platform. The organization is governed by a Board of Directors chaired by Jeremy Osborn and led by Executive Director Anne Jellema (of the parent 350.org Action Fund). 350 Action operates as a legally distinct entity but functionally integrated with 350.org, with no venture funding, no technology product, and no AI capabilities.

Scale indicators6 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Natural Resources Defense Council (NRDC): Large, well-established environmental advocacy organization with a broader policy/litigation remit and an affiliated political arm (NRDC Action Fund) — overlaps on climate advocacy and 501(c)(4) endorsement activity, but operates at a much larger scale and wider scope.
• Environmental Defense Fund (EDF): Major environmental NGO with a political action arm (EDF Action) that conducts endorsements and electoral advocacy — comparable climate-political intersection but EDF's primary focus is broader scientific/policy work rather than grassroots voter mobilization.

Direct peers

• Common Cause: Nonpartisan government accountability and civic participation organization that runs voter mobilization, election protection (poll monitors), and reform advocacy — strong overlap with 350 Action's civic-engagement and election-integrity work, though broader than climate.
• Sierra Club: One of the oldest U.S. environmental organizations with a dedicated political arm (Sierra Club Political Committee) that endorses candidates, mobilizes voters, and runs environmental electoral campaigns — directly comparable mission and 501(c)(4) structure.
• MoveOn: Progressive civic engagement organization running voter mobilization, candidate endorsements, and rapid-response political campaigns with a community-driven model — same electoral organizing DNA as 350 Action, with overlapping progressive donor base.
• Greenpeace USA: U.S. arm of a global environmental advocacy network that combines climate activism, voter mobilization, and political accountability campaigns — comparable climate mission and advocacy tactics, though less explicitly electoral.
• League of Conservation Voters (LCV): National environmental political advocacy organization that endorses candidates, runs the LCV Action Fund (a 501(c)(4)) for electoral work, and maintains a federal/state scorecard program — closely comparable to 350 Action's climate-focused endorsement and GOTV model.

Emerging players

• Sunrise Movement: Youth-led climate movement focused on electing progressive climate champions (e.g., Green New Deal endorsement strategy) and pressuring Democratic incumbents — comparable climate-electoral mission with similar GOTV tactics, though smaller and more youth-focused than 350 Action.
• Hip Hop Caucus: Civic engagement organization mobilizing young people and communities of color through voter registration and GOTV — comparable grassroots voter mobilization model targeting similar progressive-leaning demographics, though not exclusively climate-focused.
• Climate Hawks Vote: PAC specifically dedicated to electing climate champions and defeating climate deniers — directly comparable climate-electoral mission with endorsement and electoral accountability functions, though smaller and PAC-structured rather than 501(c)(4).
