350.org is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis - the solutions that science and justice demand. Its 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.
The focus is on the number 350 - as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. But 350 is more than a number - it's a symbol of where we need to head as a planet.
On 24th October all over the world, citizens took part in an international day of action.
