The aim of the project is to develop a new modeling approach to estimate the net change in GHG emissions (CO2 and CH4) due to the introduction of a reservoir. The model estimates Net GHG footprint taking into consideration the GHG footprint of the landscape prior to impoundment, the particular environmental setting of each reservoir (climatic, geographic, edaphic and hydrologic), the temporal evolution of the GHG emissions over the lifetime of the reservoir, the displaced GHG emissions, i.e. emissions that would have occurred somewhere else in the aquatic network regardless of the presence of a reservoir and the different methane (CH4) emissions pathways: Diffusive, Ebullition, Degassing.

The objective of the project is also to integrate global information for over 6000 reservoirs in order to revisit the global Net GHG footprint of reservoirs.
