At the CHE-VERIFY Joint General Assembly, Richard Engelen (ECMWF) introduces the progress and plans for the CHE WP6. WP6 (International Stakeholder Coordination and Liaison) will initiate and maintain the liaison with the European Commission, ESA, Task Forces A and B and other stakeholders, such as Copernicus services, GCOS, GAW, IG3IS, CEOS/CGMS, GEO, WIGOS, and UNFCCC. In addition, CHE will seek input from stakeholders from the user community, such as the European Commission and national inventory builders. It will organise workshops to discuss elements of the CO2 emission monitoring system with the wider community and coordinate with international collaborations and existing or upcoming project initiatives. WP6 will raise awareness of the work performed and documented in WP1-5, sharing it beyond the CHE consortium and with key stakeholders.
