Description
Transparent and internationally agreed methods to measure greenhouse gas emissions and removals are essential for effective climate policy. However, monitoring, reporting, and verification (MRV) of GHG emissions and removals from the AFOLU sector—such as from afforestation, deforestation, and land-use changes—present numerous challenges. Sound MRV requires assessing complex natural and human-driven processes that vary spatially and temporally. Uncertainty around future climate impacts (including potential feedback effects from climate system tipping points) adds complexity. Interactions between agricultural inputs such as fertilisers with soils and the atmosphere also create measurement challenges. In other cases, multiple methods exist and can give different results, creating confusion.
This session will discuss challenges and possible solutions to improve GHG estimations in the AFOLU sector, including the use of satellite imagery to track land-use changes, the impacts of wildfires and other extreme weather events on AFOLU GHG emissions and stocks, and how to better align methods across contexts. It will also discuss best practices for aligning approaches and knowledge sharing, including addressing knowledge gaps in developing countries.
