A new study from MIT Sloan School of Management found that carbon credit prices depend more on who is buying than on the actual climate impact of the project. Researchers analyzed over 7,200 transactions between 2018 and 2024, covering roughly 11% of the global secondary carbon credit market by dollar value. They found that prices varied wildly for the same type of credit, with many buyers paying a premium for projects that aligned with their mission or offered co-benefits beyond carbon reduction. The study challenges the idea that carbon credits function like a simple commodity market. Instead, buyer identity and project narrative play a major role in pricing. This has implications for companies relying on offsets for net-zero claims and for the transparency of the voluntary carbon market overall. For market participants, the findings suggest that pricing is not purely driven by the ton of CO2 reduced. Project characteristics and buyer preferences create significant price dispersion, which could affect how credits are valued and traded going forward.

This lines up with what a lot of us have suspected. The voluntary market has always been a bit of a black box on pricing. Good to see some real transaction data instead of just averages.

The bit about buyers paying for a story is key. If a carbon credit is just a ton of CO2, it should trade like a commodity. But if it comes from a community project or something with co-benefits, the price jumps. That is a feature, not a bug, for some buyers.

I wonder how much of that price variation is just lack of liquidity and information asymmetry. A broker with 7,200 transactions is a decent sample, but the market is huge. Would like to see how this plays out as more exchanges and standards mature.

The MIT Sloan angle gives it some weight. They looked at actual broker records, not just survey data. If buyer identity matters more than project type, then the whole net-zero claim hinges on who you buy from, not just what you buy.

This is a problem for regulators trying to standardize carbon accounting. If the same ton of reduction can cost $5 or $50 depending on the buyer, how do you compare corporate claims? The market needs more price transparency, not just more volume.
