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, 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.
