Sustainability is increasingly important in facility management (FM). With a rising focus on Environmental, Social and Governance (ESG) regulatory requirements - especially EU Taxonomy, Corporate Sustainability Reporting Directive (CSRD), and associated European Sustainability Reporting Standards (ESRS) - companies must address sustainability both strategically and operationally in building operations. While existing ESG tools for monitoring building performance and collecting relevant KPIs focus on technical building management, the social dimension of sustainability, which is especially important in infrastructural FM while coordinating external service providers, remains underrepresented. The aim of this paper is to evaluate the relevance of ESG criteria for infrastructural FM and to develop a standardized evaluation framework for use by corporates and facility service providers. First, relevant ESG criteria for controlling, monitoring, and reporting sustainability in infrastructural FM are derived from the internationally recognized Global Reporting Initiative (GRI) framework. Next, the existing gefma ESG-K PI tool is extended to include these criteria by mapping ESG criteria to GRI categories. The criteria are moreover weighted using a scoring tool that rates them from “not fulfilled” to “best practice”. The developed model is validated using data from real university buildings and demonstrates that transparent measures to improve ESG performance can be systematically identified and implemented. The model can be used in any role, such as property management, FM, and FM Service providers, enabling application across the various responsibilities within the context of ESG. The developed framework supports the structured collection and evaluation of o perational sustainability information that can contribute to ESG reporting processes.
