GHG reporting

Mitigating climate change is one of the most important goals for strategic sustainable development. There is a clear and pressing need to quantify the greenhouse gas footprint of all human activities.

The greenhouse gas status of freshwater reservoirs – that is, any change in the GHG emissions in a river basin resulting from the creation of such a reservoir – has been the focus of a multi-year, multi-stakeholder research project led in partnership by IHA and the UNESCO Chair for Global Environmental Change.

This session will introduce the results of this project and launch the G-res tool. The session will outline a new conceptual framework that reflects a net emissions approach, which takes into account pre-impoundment conditions and naturally occurring emissions. The G-res tool is an online tool that builds upon this methodology and will enable users to estimate the GHG footprint of reservoirs, including hydropower reservoirs. The tool also takes into account emissions related to other human activities, infrastructure construction, and allocates emissions to various reservoir purposes. Researchers, tool developers and end users will share their insights on the development of the tool and their experiences of using the tool and its potential impact for future project development.
