350 PPM

"350 is the number that leading scientists say is the safe upper limit for carbon dioxide--measured in "Parts Per Million" in our atmosphere. 350 PPM--it's the number humanity needs to get back to as soon as possible to avoid runaway climate change" (http://www.350.org/understanding-350#2).

We can change even more with totally clean energy. Please see www.terrahumanafoundation.org for more information.
