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.

This October [2010] we're organizing a 'global work party' all over the world. People will put up solar panels, dig community gardens--and send 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.
