Unformatted text preview: Stabilization Wedges Solving the Climate Problem Present carbon emissions level: ~ 7 GtC/year Assertion : we can solve the carbon and climate problem in the next 50 years by applying known technologies BAU reaches 14 GtC/yr. by 2050 Sci. Am. September 2006 , p. 50; also see suppl. material for Science 305 , 968 BAU business as usual 1.5%/yr avg growth rate Stabilization Wedges Solving the Climate Problem Present carbon emissions level: ~ 7 GtC/year A wedge starts at zero and reaches 1 GtC/yr. by 2056 Total additional carbon in the BAU is 175 GtC from 2006-2056 Each wedge removes a total of 25 GtC by 2056 Seven wedges applied to reach 1 GtC/yr saved each by 2056 = 175 GtC Sci. Am. September 2006 , p. 50; also see suppl. material for Science 305 , 968 BAU business as usual 1.5%/yr avg growth rate why a wedge? Stabilization Wedges Solving the Climate Problem Of course, to achieve stabilization at any level requires that ultimately the emissions drop to zero This scenario if followed to 2056 would leave us at about 500 ppm CO 2 Scenario assumes 2% growth in energy con- sumption/year Uncertainties : population, C sources/sinks...
