In 2010, the Hydropower Sustainability Assessment Protocol was launched as a multistakeholder, international and voluntary tool to assess performance of Hydropower Projects according to sustainable topics related to environmental, social, technical and financial aspects of the project.

The protocol was developed by the International Hydropower Association (IHA) and representatives of state governments, financial organizations, NGOs, international hydropower industry, and experts.

The protocol is the result of many years of intense dialogue among  these stakeholders which produced the selection of sustainability criteria of good and best practices for the development of hydropower.

The protocol includes four assessment tools that have been designed to be used individually and can be applied in four stages of the project cycle: – early (planning), preparation (design), implementation (construction) and operation.

The application of the Protocol allows the projects to evidence the performance in about 20 topics, with a set of scores that can show project performance regarding basic good practice and proven best practice.

Currently, there are more than 25 countries in the world where the Protocol has been applied and five of those are in Latin America.

More details about the protocol and results of the application of the protocol around the world can be found at the following link

The scoring system of the Protocol is as follows:

5 – Meets basic good practice and proven best practice

4 – Meets basic good practice with one significant gap against proven best practice

3 – Meets basic good practice with more than one significant gap against proven best practice

2 – One significant gap against basic good practice

1 – More than one significant gap against basic good practice
