The G-res Tool is designed to help hydropower companies and researchers estimate and report the net greenhouse gas emissions of a reservoir.
Reporting results gained using the G-res Tool will give investors, regulators and local communities greater confidence in a reservoir’s climate profile and carbon footprint.
Reliable and cost-effective
Hydropower, when planned and designed correctly, is regarded to be among the lowest-carbon sources of renewable electricity generation.
Before now, however, there was no reliable and cost-effective way of estimating the emissions created from building a reservoir, taking into account pre-existing conditions and naturally occurring emissions.
A decade in development, the GHG Reservoir (G-res) Tool was created through a multi-stakeholder research project led by the International Hydropower Association (IHA) and the UNESCO Chair in Global Environmental Change.
The tool uses 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).
“The development of the G-res Tool is a major milestone in the research on GHG from reservoirs. This is the first scientifically based tool for planners and designers to quantify reservoir emissions.”
– The World Bank
“Another innovative feature of the G-res Tool is its ability to calculate the net impact of a future reservoir on the GHG regime of a particular site. This is a significant breakthrough.”
– Yves Prairie, UNESCO Chair in Global Environmental Change
“As a consultant, I can see growing demand for GHG emissions estimates in tenders for hydropower projects globally. Thanks to the training I received on the G-res Tool, I can now provide clients with cost-effective GHG emissions analyses as a certified user.”
– Karin Grandin, Sweco
“The G-res Tool helps non-scientists to easily measure a reservoir’s carbon emissions. With ongoing improvements to suit different climate regions, the tool provides a convenient approach for hydropower operators and companies, such as Sarawak Energy, to estimate the greenhouse gas profile of a reservoir.”
