About 350

350.org is building the global grassroots climate movement that can hold our leaders accountable to science and justice.

350 uses online campaigns, grassroots organizing, and mass public actions to oppose new coal, oil and gas projects, take money out of the companies that are heating up the planet, and build 100% clean energy solutions that work for all. 350's network extends to 188 countries.

How do we work?

We believe in a safe climate and a better future — a just, prosperous, and equitable world built with the power of ordinary people. Here’s how we get there:

1) Keep carbon in the ground

  • Revoke the social license of the fossil fuel industry
  • Fight iconic battles against fossil fuel infrastructure
  • Counter industry/government narratives

2) Help build a new, more equitable zero-carbon economy

  • Promote investment in community-based sustainability solutions
  • Support communities confronting the impacts of climate change & building climate solutions for an economy free of fossil fuels

3) Pressure governments into limiting emissions

  • Run local and national campaigns targeting leaders
  • Capitalize on big regional and international events, like climate negotiations and economic summits

Principle #1:

We Believe in Climate Justice

Climate change isn't a distant, abstract problem — it's here now. People all over the world are feeling the impacts, from island nations that are going underwater, to indigenous land being exploited for fossil fuel extraction. The fight against climate change is a fight for justice.

That means listening to the communities who are getting hit the hardest, and following the leadership of those who are on the frontlines of the crisis.


Principle #2:

We're Stronger When We Collaborate

Climate change is not just an environmental issue, or a social justice issue, or an economic issue — it's all of those at once. It's one of the biggest challenges humanity has ever faced, and we are going to have to work together to solve it.

That means bringing people together — not just environmentalists, but students, business owners, faith groups, labor unions, universities and more — and building diverse coalitions that are strong enough to put pressure on governments and stand up to the fossil fuel industry.


Principle #3:

Mass Mobilizations Make Change

By now, it's obvious that world leaders are incapable of solving this problem on their own. We need to get out in the streets and make our voices heard — that is how we demonstrate our power as a movement, and that is how we force our governments to make the right decisions.

350.org was founded in 2008 by a group of university friends in the United States along with author Bill McKibben, who wrote one of the first books on global warming for the general public, with the goal of building a global climate movement. 350 was named after 350 parts per million -- the safe concentration of carbon dioxide in the atmosphere.

Our first actions were global days of action that linked activists and organizations around the world, including the International Day of Climate Action in 2009, the Global Work Party in 2010, Moving Planet in 2011. 350 quickly became a planet-wide collaboration of organizers, community groups and regular people fighting for the future.

Today 350 works on grassroots campaigns across the globe: from opposing coal plants and mega-pipelines, to building renewable energy solutions and cutting financial ties of the fossil fuel industry. All of our work leverages people power to dismantle the influence and infrastructure of the fossil fuel industry.

Some of our proudest moments of recent years include campaigns against Keystone XL and Dakota Access in the United States, stopping fracking in hundreds of cities and states in Brasil, joining historic grassroots mobilizations before and after the Paris Climate Agreement was signed, and pushing hundreds of universities, foundations, cities and churches to divest from fossil fuels.
