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.

350.org is an international movement of ordinary people working to end the age of fossil fuels. We were founded in 2008, on the conviction that people are the most powerful agents of change. Our core belief is that the only way to achieve real climate justice is to strengthen, empower and grow the climate movement. We work with people across the world to oppose those wrecking our climate and to fight for a sustainable future.

Your generosity allows us to make a meaningful impact.  To find out more about our work, including our financial information, annual report and how to donate, please visit https://350.org/how-to-give/
