CMI's Stabilization Categories

Continuing our look at the Carbon Mitigation Initiative, here is a list of the different categories, and the most promising possibilities within those categories, that could be capable of producing a whole or partial wedge of abated emissions. Each wedge effectively prevents 1 billion tons of CO2 emissions per year, or 25 billion tons over the next half century. To stabilize atmospheric carbon concentrations, seven wedges are required.
