DG Energy has proposed to set up an EU Corporate Covenant initiative to encourage companies to step up their contribution to a clean energy transition and related climate objectives as set out in the European Green Deal. As a first step in this process, a comparative analysis of existing Member State (MS), EU and international company-focused voluntary emission reduction and sustainable development related initiatives was carried out by the JRC to understand their key lessons learned and success factors. Building upon the outcomes of the analysis, and taking into account best practice processes, four potential options for an EU Corporate Covenant were then developed.
