Atmospheric CO2 and CH4 Budgets to Support the Global Stocktake

To support the 2023 Global Stocktake (GST), Parties to the Paris Agreement are compiling inventories of anthropogenic greenhouse gas (GHG) emissions and removals to assess their collective progress towards the long-term objectives of the Agreement. The Global Stocktake is the process of monitoring the implementation of the Paris Agreement. The outcome of the GST will provide Parties the information needed to update and enhance their nationally determined contributions (NDCs) to the global response to climate change and strengthen international cooperation for climate action.

This three-part webinar series will introduce bottom-up and top-down methods for tracking emissions and removals of carbon dioxide (CO2) and methane (CH4) from the atmosphere. This training will explore how to combine this information to produce a more complete and transparent global stocktake, and support efforts to reduce net emissions and mitigate their impact on the climate.

Demonstrations will be provided on how top-down atmospheric budgets of CO2 and CH4 can be derived from atmospheric measurements and inverse models to produce a transparent description of their emissions and removals. Participants will also be introduced to pilot products and how information contained in these top-down atmospheric products can supplement bottom-up inventory products to assess the accuracy and completeness of emissions reports on regional, national, and local scales.
