Original source: Pacala and Socolow, Science, Note: Each “wedge” in this figure represents 1 gigaton of carbon per year; seven wedges are needed if emissions are to be brought back to current levels by 2050 globally – and because of the likely increase in demand, additional efforts would be needed post-2050 to stabilize concentrations. Pacala and Socolow identify options for 15 wedges in their analysis.
