The World Federation of Exchanges (WFE) has published a research paper providing transaction-level evidence on how prices form in the voluntary carbon market (VCM), finding persistent price inequalities between advanced economies and emerging markets and developing economies (EMDEs). The analysis links the observed premium for advanced-economy credits primarily to the rule of law and governance quality in the project host jurisdiction, rather than investor home bias. Using more than 250,000 carbon credit transactions spanning 2,200 projects between 2017 and 2024, the paper finds nature-based credits (such as forestry and land use) trade at prices 67% higher than technology-based credits (such as renewable energy). Older vintages trade at 9–23% discounts, larger available inventories are associated with lower future returns, and past returns alongside prior inventory levels are the strongest predictors of near-term price movements. Even after adjusting for project characteristics, credits from advanced economies are priced 28% higher on average than those from EMDEs, and credit retirements peak in December in line with corporate sustainability reporting cycles and offset deadlines.
