The main goal of the Communication, Dissemination & Stakeholder Engagement activities carried out under Blue-Cloud's WP5 was to raise awareness of, disseminate, and facilitate early adoption of the Blue-Cloud assets, including Key Exploitable Results (KERs), among target stakeholder groups. The Blue-Cloud "D5.4 Communication, Dissemination & Stakeholders Engagement Final Report, including events" reports on the activities and achievements of the project from M19 (April 2021) to M42 (March 2023), building on the "D5.2 Communication, Dissemination & Stakeholders Engagement Interim Report", which covered efforts from the project start up to M18 (March 2021). The main focus of the project during the M19-M42 reported period was to consolidate stakeholder engagement for each target group by disseminating the project's KERs towards promoting uptake and wider exploitation. Aside from the dissemination of technical results, this period was also dedicated to further promoting dialogue and engagement with key stakeholder communities towards the Blue-Cloud Roadmap to 2030, which produced policy recommendations for the further evolution of Blue-Cloud into the decade.
