CO2 is a gas: the invisible image of expended carbon, and a spent natural resource. CO2 currently comprises more than 380 parts per million of the earth's atmosphere, and it is rising. 350 parts per million is the optimum level for life as we know it, probably the best level for people and all of nature to prosper.

It is the responsibility of all of us to reduce CO2 emissions and spend our carbon more carefully. This document outlines the actions we need to take.
