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.

Hydropower Sustainability Assessment Protocol

The International Hydropower Association (IHA) played a leading role in the development and implementation of the Hydropower Sustainability Assessment Protocol – a framework for assessing projects against a comprehensive range of social, environmental, technical and economic considerations.

The protocol was shaped by representatives from governments, commercial and development banks, social and environmental NGOs, and the hydropower sector.

To support its implementation, we are building partnerships with leading hydropower companies to guide improvement across different project stages and contexts.
