D6.6 provides a first outline on the planned collaboration and synergies between the EU H2020 projects CHE and VERIFY. The document therefore provides the plans in the following areas:

• Interaction with inventory agencies & DG CLIMA
• Input to international programmes and society
• Sharing of CHE nature runs and feedback from VERIFY.
• VERIFY CIF – test bed for future Copernicus service and use in CHE
• Estimation of CH4 emissions in VERIFY
• VERIFY input to CHE Strategic Research Agenda documents and vice versa
• Coordinated planning of project meetings
• Participation in advisory boards

These synergetic opportunities have been agreed between the two projects and any future new opportunities for collaboration will be included in future versions of this document.
