In a long anticipated move, Southern California Edison May 16 sought approval of eight carbon offset projects under the California Air Resources Board’s early actions policy. The Air Board policy is intended to grant emissions reduction credits to companies under the state’s climate protection law, AB 32. “By acting now,” said Edison president John Fielder, “we can achieve greenhouse gas reductions that likely will be substantially less costly for customers than when the final rules implementing the law take effect.” Edison estimates that the eight projects will eliminate the equivalent of 3.7 million metric tons of carbon dioxide emissions a year, about the same as taking 800,000 cars off the road. Edison’s “program calls for independent state validation before we begin these projects,” said Michael Hertel, Edison environmental policy director, “plus strict results measurements after the projects are in operation.” The cost of the projects, which Edison estimates would total $23 million, is to be recovered through higher rates for customers, the utility said. The projects include: -Converting truck stops to operate with electricity in order to keep trucks from idling while drivers rest in cabs; -Making power from livestock waste; -Advancing plug-in hybrid vehicles; -Planting 70,000 trees in urban areas to capture carbon; -Switching agricultural pumps from diesel fuel to electricity; -Recovering methane, a powerful greenhouse gas, from abandoned mines and burning it as fuel to diminish its contribution to climate change; and -Cutting emissions of sulfur hexafluoride, a greenhouse gas used in equipment embedded in the power distribution system. Edison needs approval from both the California Public Utilities Commission and California Air Resources Board to proceed.
