350.org is an international campaign that's building a movement to unite the world around solutions to the climate crisis—the solutions that science and justice demand.
Our mission is to inspire the world to rise to the challenge of the climate crisis—to create a new sense of urgency and of possibility for our planet.
Our focus is on the number 350—as in parts per million CO2. If we can't get below that, scientists say, the damage we're already seeing from global warming will continue and accelerate. But 350 is more than a number—it's a symbol of where we need to head as a planet.
We work hard to organize in a new way—everywhere at once. In October of 2009 we coordinated 5200 simultaneous rallies and demonstrations in 181 countries, what CNN called the 'most widespread day of political action in the planet's history.' In October 2010 we organized a 'global work party' all over the world, with over 7000 events in 187 countries. People put up solar panels, dig community gardens—and sent a strong message to our leaders: 'If we can get to work on solutions to the climate crisis, so can you.'
Our theory of change is simple: if an international grassroots movement holds our leaders accountable to the latest climate science, we can start the global transformation we so desperately need.
