California Carbon Offset Program Judged Effective by Stanford University Study

The new study determined that carbon forestry offsets, which allow polluters to reduce carbon emissions out-of-state rather than in impacted communities near large pollution sources, is a beneficial climate program.

A controversial California climate program, condemned by environmental justice advocates because it allows large emitters, like oil refineries, to spend funds out-of-state rather than reducing emissions in impacted communities surrounding their facilities, was found to have a positive impact on mitigating climate change.

“Offsets are loopholes for our largest corporate polluters,” said Amy Vanderwarker, co-director of the , in a March Los Angeles Times article on the program.

The offset program is part of California's cap-and-trade program, the only state-run carbon trading program in the nation, that expires at the end of 2020. Offsets were eliminated from SB 775, an unsuccessful bill to continue the program through 2030, but were included in AB 398, which passed the legislature last month with bipartisan support and was signed by Gov. Jerry Brown.

"According to the researchers’ findings, that program is protecting imperiled forests and preventing the carbon they store from being released into the atmosphere," reports energy & environment contributor Chelsea Harvey for The Washington Post.

"Forest offsets, which account for the majority of offsets in California’s cap and trade market, involve forest owners changing the way they manage their land so trees will store more carbon," reports Rob Jordan for the Stanford News on the research published August 14 in the journal, Frontiers in Ecology and the Environment.

This could involve cutting trees less often, reforesting previously forested land or improving forests through various management practices. Under any scenario, professional foresters vet the changes to ensure they are effective.

"The new study suggests some of the concerns surrounding the program may not actually be cause for worry — at least for now," adds Harvey.

Offsets are not only controversial, they are a super complicated thing to get right,” explains Michael Wara, a former climatologist and environmental law expert at Stanford University who was not involved with the new research, writes Harvey.

In some sense, forest carbon is trading one kind of co-benefit for another kind of co-benefit,” Wara said. “It’s not strictly a benefit, it’s a trade-off, because we’re going to burn more carbon in California in exchange for storing more carbon elsewhere.”

The new cap-and-trade legislation is sensitive to the concerns of environmental justice advocates. It establishes a "Compliance Offsets Protocol Task Force to provide guidance to the state board in approving new offset protocols ... for the purposes of increasing offset projects with direct environmental benefits in the state while prioritizing disadvantaged communities, Native American or tribal lands, and rural and agricultural regions."
