SBTi Releases Scenarios for Carbon Credits Despite Finding Little Evidence They Work

The world’s leading referee on corporate net-zero targets left open the possibility of allowing companies to use carbon credits in their efforts to reduce emissions, but said more research was needed after a review of evidence found that many credits are largely ineffective.
The findings, released Tuesday, mark the latest development in a monthslong saga that has put the Science Based Targets initiative, or SBTi, at the forefront of a global debate over whether carbon credits have a legitimate place in voluntary corporate climate commitments.
SBTi relies on scientific evidence to verify companies’ emissions reduction plans and has validated climate targets for more than 5,000 companies to date.
“The outputs released today are a critical step in understanding how the SBTi can develop a more sophisticated approach to scope 3 to help more businesses set targets,” Alberto Carrillo Pineda, SBTi’s chief technical officer, said in a statement.
In a discussion paper, also released Tuesday, the SBTi outlined potential uses for carbon credits, but it didn’t commit to incorporating any into a forthcoming policy update.
In one scenario, companies could use carbon credits to show emissions reductions in their supply chains.
In another, the credits could be used to offset so-called “residual emissions,” or roughly 10% of emissions that remain unabated as part of companies’ net-zero goals. In a third scenario, companies could buy carbon credits to mitigate emissions outside their supply chains.
The scenarios are part of a lengthy review process and won’t necessarily make their way into the SBTi’s updated net-zero standard expected to take effect next year
