G-res Tool

Assess and report the net greenhouse gas emissions of a reservoir


The G-res Tool is a web-based tool for hydropower developers and researchers to assess and report the carbon footprint of a reservoir.

Using readily available input data, the tool provides a cost effective way to more accurately assess net greenhouse gas (GHG) emissions.

A decade in development, the G-res Tool was first launched in 2017 as part of a multi-stakeholder research project led by the International Hydropower Association (IHA) and the UNESCO Chair in Global Environmental Change.

The G-res Tool was developed using a conceptual framework created with scientists from the University of Quebec at Montreal (UQAM), the Norwegian Foundation for Scientific and Industrial Research (SINTEF) and the Natural Resources Institute of Finland (LUKE), with assistance from the World Bank.

Assess. Validate. Report.

Assessing the net GHG emissions of a reservoir is now an expectation for sustainability reporting and a requirement for financing a hydropower project through climate finance.
