Hydropower Sustainability Standard
The HSA is a globally recognised certification system that ensures accountability upstream and provides assurance downstream across the hydropower value chain. It enables stakeholders - including developers, operators, financiers and governments - to demonstrate their commitment to sustainability.

Each section is guided by clear principles and scope statements, ensuring transparency and consistency in the assessment process. By adopting the HSS, stakeholders can strengthen their ESG performance and align with global best practices.
