ALEXANDRE MENEGHINI/Reuters A carbon credit dealer has a new strategy for making its riskier offerings more palatable and affordable to companies: Packaging them with credits based on good, old-fashioned tree planting. Almost all carbon credits are based on avoided emissions: Buy the credit, and a patch of forest that would have been cut down will be left standing. Most experts agree that a more credible and climate-beneficial approach is carbon removal: Activities, such as tree planting or high-tech carbon-sucking machinery, that draw down existing atmospheric CO2. An Oxford University report this week warned that today’s carbon market will have little long-term benefit to the climate unless that ratio flips within the next few years. The challenge is that most forms of carbon removal are orders of magnitude more expensive than carbon avoidance, with a pool of buyers limited to a handful of rich tech companies that are willing and able to shell out hundreds of dollars per ton. Rubicon Carbon, a carbon credit company, launched a new product this week that allows buyers to purchase a share in a diversified portfolio of carbon removal projects. About 95% of the portfolio consists of tree-planting initiatives, which have the benefit of being cheap, but don’t guarantee permanent carbon storage (trees sometimes get cut down), and have geographical limits since there’s not enough space on Earth to plant enough trees to reach net zero. The remaining 5% is made up of a mix of more expensive, but longer-duration, tech-based carbon removal projects. A share of the portfolio is cheaper than a standard carbon removal credit, and Rubicon promises to actively manage the portfolio to filter out removal startups that will inevitably fail, as well as bring in new technologies as they become available. The idea is to give buyers a way into carbon removal that’s more reliable and less prone to greenwashing than a typical carbon offset, but still cheaper for a company than directly reducing its in-house emissions, chief science officer Jennifer Jenkins told Semafor (she declined to say how much Rubicon is currently charging for a share). That type of approach could help scale removals up. But government regulators still need to do more to weed bad credits out, Oxford researcher Kaya Axelsson said: “In any other market, there would be consumer protection standards that we simply don’t have in the carbon market today.” |
