Biodiversity credits should not copy carbon markets: why one tradable unit is the wrong goal

An op-ed republished by Reccessary argues that biodiversity credit markets should not follow the carbon market model of reducing everything to one tradable unit. The author points to the huge gap in market size estimates, ranging from $90 million to $7.1 billion for 2025, as evidence that there is no shared definition of a biodiversity credit. Unlike tCO2e, a hectare of mangrove and a hectare of grassland cannot be treated as interchangeable without losing ecological meaning. The piece also draws on carbon market failures, including the 2023 investigation that found most Verra rainforest offsets were likely worthless and the 2024 criminal charges against a former C-Quest Capital CEO. The lesson for biodiversity markets is to build verification around continuous, independent checks rather than a single elegant number. For readers tracking carbon market integrity, the op-ed frames biodiversity credit design as a chance to avoid repeating the same mistakes.

The argument is that biodiversity credits are not carbon offsets. A hectare of mangrove is not interchangeable with a hectare of grassland, so forcing one tradable unit creates the same verification risks carbon ran into. The 80x gap in market size estimates is really a definition problem. Worth reading for anyone in carbon markets.

That Verra case is the part that should worry people. More than 90% of rainforest credits were called likely worthless, then a former Verra board member got indicted over over-issuance. If biodiversity markets copy that structure, they inherit those incentives.

One practical question: what does continuous independent verification look like for biodiversity? Forest cover is easy to check from a satellite. Wetland function or species presence is not. That is a much harder claim to verify than a ton of CO2.

The article separates commensurability from ecological meaning. That tension is real. But buyers and regulators want a number they can put in a report. If you reject a single unit, you need an alternative framework for comparing projects, or demand will stay thin.

Interesting op-ed from Mongabay republished by Reccessary. Main takeaway: don't build biodiversity markets around a single unit. The lack of a shared definition is why market size estimates range from $90M to $7.1B. Good context for carbon market folks.
