GCC: Berkeley study finds California cap-and-trade program falling short of goals

California regulators are overestimating the impact the state’s cap-and-trade system is having on reducing greenhouse gas emissions, according to a new policy brief from a researcher at UC Berkeley’s Center for Environmental Public Policy, part of the Goldman School of Public Policy.

In the paper, research fellow Barbara Haya argues that the California Air Resources Board has made optimistic assumptions about a program protecting forests that may only have accomplished 18% of the emission reductions it claims have been made.

The discrepancy could be as much as 80 million tons of carbon dioxide since 2013—equivalent to more than the total annual emissions from California’s entire electricity sector. . . .

At issue is California’s US Forest Projects offset protocol, an incentive program designed by the state to encourage forestland owners across the country to manage forests in ways that increase the amount of carbon stored in them. These arboreal stores of carbon create credits that California’s industrial polluters, like power plants, can then buy to offset their own emissions.

But the economy still requires lumber for housing or furniture and wood pulp for paper. And that’s where California’s system runs into trouble, Haya said. Even when forestland owners change their logging practices, the demand for lumber or paper doesn’t decrease, it shifts to other forests.

California assumes that 20% of timber harvesting reduced by California’s forest offset protocol is done in forests that are not part of the cap-and-trade system to meet timber demand, and the state accounts for that when it issues carbon credits.

But that 20% figure, called a leakage rate, is not supported by academic literature, Haya found. It’s more accurate to say that, in California’s program, 80% of the reduction is shifted to other forests. . . .

Another problem Haya’s analysis found was a question of when the effects of this leakage rate, whether it is 20% as the state claims or 80% as Haya argues, are accounted for.

Under the current policy, timber companies and other landowners get immediate credit in the cap-and-trade market for deciding to preserve their forests. But the deduction for all the trees still cut down because of demand for wood products—leakage—is applied over the next 100 years.

This system of early reward, Haya said, creates a cap-and-trade market flush with carbon credits that polluters can buy to avoid reducing their own emissions in the short term. . . .
