Pierre J. D., Mungroo Z. B. A., Tupsee R. S. (2025). Case Study on Market Mechanism Impacts on Leakage Patterns.
These submissions were presented to the UNFCCC Article 6.4 Methodological Expert Panel at its fourth meeting in response to a formal call for inputs on carbon leakage in mechanism methodologies. They present a systematic review of leakage quantification methods, a case study on MRV technology adoption, and an econometric analysis of market mechanism impacts on leakage patterns — including spatial econometric modelling and difference-in-differences analyses across 25+ carbon markets. Relevant to climate economists, MRV specialists, and UNFCCC methodology practitioners.
