In the context of providing recommendations for the implementation of an observation-based operational anthropogenic CO2 emissions Monitoring and Verification Support capacity (CO2MVS) within the Copernicus programme, one of the main objectives of CoCO2 is to provide inputs to the Global Stocktake (GST) process in time for the 1st GST in 2023, as well as more comprehensive inputs for the subsequent five-year GST cycles.
Specifically, it is foreseen that CoCO2 will already provide appropriate CO2 anthropogenic emission products for the 1st GST, at a spatial scale consistent with GST requirements. For the longer term, research developments within other CoCO2 work packages will be channelled into building a comprehensive multi-scale prototype that will serve as the basis for the pre-operational Copernicus CO2 service, with the view of delivering CO2 emission and removals estimates on time for the 2nd GST with the best possible accuracy.
Task 6.2 of the CoCO2 project is therefore aimed at identifying relevant needs for the periodic Global Stocktake through the development of a User Requirement Document (URD), as the starting point to define the prototype functionalities for a timely support of the GST. This deliverable (D6.3) represents an update of the URD developed under the VERIFY project (VERIFY, 2019; Perugini et al. 2021), with several integrations taking into account the needs of the GST process and the latest COP26 outcomes.
The challenge that the CoCO2 project is facing is the creation of a system that is compatible with the multilateral process within the UNFCCC. This means being able to develop products that can adequately support countries in improving their reporting over time, in line with the methodologies and requirements under the Convention and the Paris Agreement, including transparency arrangements under the new Enhanced Transparency Framework (ETF) and the GST process, which will continue being the frameworks guiding countries’ efforts over the next decades.
