What We Do

350.org is building a global climate movement. Our online campaigns, grassroots organizing, and mass public actions are coordinated by a global network active in over 188 countries.

The number 350 means climate safety: to preserve a livable planet, scientists tell us we must reduce the amount of CO2 in the atmosphere from its current level of 400 parts per million to below 350 ppm.

We believe that a global grassroots movement can hold our leaders accountable to the realities of science and the principles of justice. That movement is rising from the bottom up all over the world, and is uniting to create the solutions that will ensure a better future for all.

With over 4000 languages spoken around the world, words don’t always get the point across. This wordless animation explains 350.org in 90 seconds:

Our History

350.org was founded by a group of university friends in the U.S. along with author Bill McKibben, who wrote one of the first books on global warming for the general public.

When we started organizing in 2008, we saw climate change as the most important issue facing humanity — but climate action was mired in politics and all but stalled. We didn’t know how to fix things, but we knew that one missing ingredient was a climate movement that reflected the scale of the crisis.

So we started organizing coordinated 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, and Climate Impacts Day in 2012. We held the “world’s biggest art installation” and “the most widespread day of political action in the planet’s history.” We figured that if we were going to be a movement, then we had to start acting like one.

Today, 350.org works in almost every country in the world on campaigns like fighting coal power plants in India, stopping the Keystone XL pipeline in the U.S, and divesting public institutions everywhere from fossil fuels. All of our work leverages people power to dismantle the influence and infrastructure of the fossil fuel industry, and to develop people-centric solutions to the climate crisis.
