As for the carbon footprint calculation, an emission inventory approach has been followed considering the sources of emissions inside the Living Labs’ areas and including electricity consumptions and waste management using CO2equivalent emissions. To compute CO2 equivalent emissions, specific emission factors in the Living Labs have been used when available, otherwise standard emission factors. A set of short-lived climate forcers and air pollutants were also taken into consideration in the modelling evaluation.

The analysis of the data available at Living Lab level has enabled the identification of the areas of intervention of the Living Labs for which it is possible to define and apply a calculation methodology. These areas are road traffic, energy consumption and waste management. As for road transport, the data about number of vehicles in the road network obtained by traffic simulations has been used as input. Traffic simulations have been conducted for the peak hours and day and, for the purpose of the report, have been scaled to annual mileage utilizing typical factors. In addition, the carbon footprint has been modelled for the residential sector of the Amsterdam Living Lab and the waste management in the Ouagadougou Living Lab.

Finally, the E2GovCmty model has been introduced. The model is a customization of the more general E2Gov model to store data and to evaluate the I-CHANGE carbon and environmental footprint.
