EYE-CLIMA: Verifying Emissions of Climate Forcers

Context

The Global Stocktake, and the success of the Paris Agreement, hinges on the information nations provide about their emissions through National Greenhouse Gas Inventories. Current methodologies, laid-out by the IPCC for reporting emissions, are generally built around the use of statistical data and emission factors. Although they are designed to be transparent, they can have significant uncertainties owing to incomplete or inaccurate information. The 2019 refinement of the IPCC Guidelines highlights the need for independent verification of these inventories, especially using atmospheric observations. However, the technical complexity makes this very challenging.

Objectives

external page EYE-CLIMA will address this need for independent verification by developing observation-based methods (using both satellite remote sensing and ground-based observations) to a level of readiness where they can be used to determine emissions at national and sub-national scales and for verification of National Greenhouse Gas Inventories.
