The Net Climate Value of Carbon Credits: Pricing Leakage, Time, and Reversal 1: University of Lorraine, University of Strasbourg, AgroParisTech, CNRS, INRAE, BETA, 54000 Nancy, France; 2: Climate Economics Chair, Palais Brongniart, Paris, France; 3: Department of Land Economy, Centre for Environment, Energy and Natural Resource Governance (C-EENRG), University of Cambridge, Cambridge CB2 3QZ, UK; 4: Oeko-Institut, Germany; 5: Department for Innovation in Biological, Agro-Food and Forest Systems (DIBAF), University of Tuscia, Italy; 6: National Museum of Natural Sciences (MNCN), National Spanish Research Council (CSIC), Spain; 7: University of Ljubljana, Slovenia; 8: Natural Resources Institute Finland, Helsinki, Finland; 9: European Forest Institute, Finland; 10: Austrian Research Centre for Forests (BFW), Vienna, Austria; 11: Universidad de Alcala, FORECO, Departamento de Ciencias de la Vida, Madrid, Spain Forest carbon offsetting assumes a credited tonne is equivalent to an emitted one. After on-site verification, three downstream deductions—market leakage, finite storage duration, and reversal risk—reduce a credit's climate value. Prior work addresses upstream additionality or aggregate over-crediting; none prices these three deductions together from empirical data. We calibrate each from published evidence and combine them into one issuance rule, applied to sixteen forest practices across three European biomes with Monte Carlo uncertainty. Net climate value—the surviving share—spans 11–49%, and five European schemes over-credit by 32–63%. Finite storage duration is the largest deduction for most practices, yet schemes credit 30- and 100-year contracts identically. Absolute levels depend on the permanence benchmark, but rankings and the sign of every scheme's gap are invariant. As the EU finalises its Carbon Removals Certification Framework, a credit equals a tonne only when leakage, duration, and reversal are priced alongside verification. | |
