ELS Europe chaired the ‘Do No Significant Harm’ (DNSH) Handbook, a collaborative work with Maples Group and Frankfurt School of Economics. The DNSH Handbook aims to provide data producers with the information they need to effectively disclose their DNSH obligations. The case studies explored in the guide underline how owners and developers of large construction, real estate and infrastructure projects can improve the DNSH assessment and identify relevant ESG factors. Strategic decisions made early in the development pre-construction stage by developers and planners will ease the disclosure burden on all stakeholders and ensure the environmental ambitions of the project are rewarded.
