The document is a direct output of WP7 whose key role in the project is to raise awareness about project results, disseminate major outputs, and engage key stakeholders. The aim of this document is twofold:

• It gives an overview of the implementation plan to engage the EU stakeholder community on HPC for stochastic quantum chemical simulations.
• It demonstrates the impact generated by the different activities carried out so far, linking them to the main outputs produced by the TREX project.

This report outlines the communication, dissemination and engagement objectives and actions in the period up to March 2022 (M18). The document provides information on how the project has targeted the main target stakeholders through various channels such as the TREX website, social media, events, schools, and workshops. The document also reports on quantitative and qualitative measures demonstrating the impact of the project.
