This report summarizes the results of the third and final networking meeting under the VERIFY project. Focus in this meeting was the interaction with the work packages (WPs) 5 and 6, that aim at assimilating knowledge into an integrated system, applicable for EU, as well as other third parties/non-EU countries). Tools are made available through the LSCE VERIFY website https://verify.lsce.ipsl.fr/.

Main questions that were raised during this meeting were:

  • Are the results of the VERIFY synthesis plots applicable to support verification of inventories?
  • What would be a way forward for verification activities?

Inventory agencies assessed the outcome of VERIFY synthesis plots, compared them with the results of their inventories and presented their views. They showed a positive attitude towards the Community Inversion Framework (CIF), the synthesis plots and the wealth of data collected and made available via the website. Utilisation of current VERIFY synthesis tools for verification likely varies depending on the gas, sectors included/excluded and the type of independent method (bottom-up vs top-down).

For formal uptake, the comparisons need to be assessed at national level in collaboration with the inventory agencies, to allow agreements and discrepancies to be explained. Results of this work may help in both further developing the framework for verification and starting a discussion within inventory agencies on how to work with/judge the results of the models. A number of suggestions were made for further development of synthesis tools.

Continued and enhanced exchange between national inventory compilers and scientists is recommended. Such exchange, that so far largely takes place within the scope of research and development projects (like VERIFY and CoCO2), will likely continue within the setting of a number of follow-up projects (e.g., EYE-CLIMA, AVENGERS, PARIS). Also the set-up of a National Collaboration Programme (NCP) under CAMS for the support of the development of a CO2MVS, may support achieving intensified and sustained collaboration.
