Reporting of performance indicators
The Fund’s ambition to increase the coverage and therefore the transparency of its environmental impact according to INREV Sustainability Reporting Guidelines is reflected in the summary of key performance indicators in the table above.
Bouwinvest reports the environmental data of those assets where management control is possible (operational control approach). Data is provided for those assets where we have the authority to introduce and implement operating policies and are responsible for purchasing energy and water and handling waste. Our management control differs greatly by asset type (e.g. residential and office); these differences affect the level of influence we have over the sustainability performance of our assets.
Like-for-like data and changes represents assets which have been fully owned and operational for the full 24 month period in our investment portfolio. It provides insight into the performance of an indicator over time at a constant portfolio scope. The reduction in GHG emissions can be explained by the compensation of carbon emissions through purchase of carbon certificates. This follows the commitment of Bouwinvest to reduce the impact its operations has on climate change.
For the managed portfolio (scope 1 and 2), Bouwinvest reports on total energy consumption including all direct energy sources (gas, fuel oil) and indirect energy sources (electricity, district heating and district cooling). To calculate Greenhouse Gas (GHG) emissions, country and energy source-specific emission factors have been applied. Emission factors change over time. For this annual report, the most recently available factors for 2017 are used (source:www.co2emissiefactoren.nl).
Energy, Emission and Water intensities are reported only on properties where energy and water data is available, using “shared services” as the numerator and lettable floor area (LFA) as the denominator. “Shared services” refer to landlord-obtained consumption for common areas and any services provided to tenant areas that have not been sub-metered.
