350.org is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis--the solutions that 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.
Environmentalist Bill McKibben has taken the lead to get everyone clued in about the number 350, the parts per million of carbon emissions that we need to return to in order to sustain life on earth.
The most recent science tells us that unless we can reduce the amount of carbon dioxide in the atmosphere to 350 parts per million, we will cause huge and irreversible damage to the earth. Together, we will redefine the possible and rally the world behind the solutions that science and justice demand.
