ESG Gap Analysis Tool



The Hydropower Sustainability ESG Gap Analysis Tool (HESG) enables hydropower project proponents and investors to identify and address gaps against international good practice.


The HESG gap analysis tool is based on the framework of the Hydropower Sustainability Assessment Protocol. It assesses projects against the requirements of the HSAP’s environmental, social and governance topics. 

The tool provides an action plan to help project teams address any gaps against good practice. It is divided into 12 sections which are compatible with IFC Environmental and Social Performance Standards and the World Bank’s new Environmental and Social Framework.

The tool was developed under the mandate of the Hydropower Sustainability Assessment Council, with the support of the Swiss State Secretariat for Economic Affairs (SECO).
