The land-use sector plays a critical role for achieving the goals of the Paris Agreement. This report discusses key environmental integrity challenges for using carbon market mechanisms to implement mitigation activities in the land-use sector. The report evaluates how existing carbon market mechanisms address these challenges in practice and to what extent these approaches can mitigate environmental integrity risks. The analysis includes selected crediting mechanisms and two case studies of cap-and-trade systems, the EU LULUCF Regulation and the New Zealand Emissions Trading Scheme.
