Sustainability
Hydropower plays a vital role in reducing the world's dependence on fossil fuels. As a renewable energy, it is essential that hydropower is developed sustainably.
The International Hydropower Association (IHA) has played a leading role in the development of the Hydropower Sustainability Assessment Protocol, which is today governed by a multi-stakeholder council.
IHA continues to act as the Protocol's management body, overseeing training and accreditation, and supporting its governance committee.
Hydropower Sustainability Assessment Protocol
The Hydropower Sustainability Assessment Protocol offers a framework for assessing hydropower projects against a comprehensive range of social, environmental, technical and economic criteria.
The Protocol was shaped by representatives from governments, commercial and development banks, social and environmental NGOs, and the hydropower sector.
The Protocol was updated in July 2018 to cover climate mitigation and resilience.

ESG Tool
The Hydropower Sustainability Environmental, Social and Governance Gap Analysis Tool enables hydropower project proponents and investors to identify and address gaps against international good practice.
Launched in July 2018, the ESG Tool is based on the framework of the Hydropower Sustainability Assessment Protocol. It assesses projects against the requirements of the Protocol’s environmental, social and governance topics.
