This Communication and Dissemination report is designed to evaluate the impact of the activities carried out under the GreenSCENT project over the past three years. The report will assess the impact both qualitatively, through case studies, and quantitatively, using the metrics established in the Dissemination Plan (D6.2).In addition to measuring the impact, this deliverable aims to enhance transparency by thoroughly reviewing the activities undertaken. It also examines the limitations and strengths, as well as identifies best practices, all with the objective of exploring insights that will inform recommendations for future European projects.This deliverable forms part of Work Package 6 (WP6) titled Impact and Outreach, which began in Month 1 (M1) and will conclude in Month 36 (M36). The University of Autonomous Barcelona (UAB) leads this work package, with contributions from all partners.UAB is responsible for managing this deliverable, with contributions from UNINETTUNO, responsible in the project of the development of the GreenSCENT website and the Barcelona Supercomputing Center (BSC), which oversees the Clustering activities within the project.
