The European Commission mandated Finance for Impact to prepare the guidance for social screening and proofing of financing and investment operations under the InvestEU programme 2012-2027. Finance for Impact first identified specific strengths and weaknesses of existing social and environmental screening methodologies and procedures used by potential InvestEU implementing partners. Then, we outlined different options for developing a dedicated InvestEU social impact scorecard, which provides an overview of a potential investee’s social performance and generates a social investment score.
