Global Greenhouse Gas Watch (G3W)

The Global Greenhouse Gas Watch (G3W) initiative is crucial for supporting the objectives of the Paris Agreement by improving the monitoring of greenhouse gas (GHG) net fluxes globally. Through enhanced observational networks and advanced data integration, G3W aims to coordinate a global technical framework to provide precise, actionable data on GHG net fluxes, helping countries track progress and make informed decisions in their climate actions.

The G3W will provide global monthly net fluxes of carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) with 1° × 1° geographic latitude-longitude grid resolution (about 100x100 km spatial resolution), aiming to reduce uncertainties and improve the reliability of GHG monitoring.

This initiative is also instrumental in addressing data gaps in critical regions, thereby enabling a more accurate assessment of global GHG net flux.
