350.org is building a global grassroots movement to solve the climate crisis. Our online campaigns, grassroots organizing, and mass public actions are led from the bottom up by thousands of volunteer organizers in over 188 countries. 350.org works hard to organize in a new way—everywhere at once, using online tools to facilitate strategic offline action. We want to be a laboratory for the best ways to strengthen the climate movement and catalyze transformation around the world.
