MERLIN Properties Annual Report 2022

78 | Annual report | 2022 Environmental performance data are reported both in absolute terms and in relative terms, known as intensity, i.e. absolute consumption or emissions divided by the surface area for which the consumption or emissions are reported. With these considerations in mind, the environmental indicators are calculated taking into account the percentage of GLA (Gross Leasable Area): • To measure the intensity of assets that are in operation for part of the year, the asset’s GLA is weighted by the time it has been in operation. This is a change from the data reported by MERLIN in previous years, which included the full GLA. • Furthermore, in the case of assets that form part of an owners’ association, the share of equity is applied to the energy and water consumption data. In these cases, the surface area taken into account in the calculations represents MERLIN’s share of equity in the asset. • Lastly, the total GLA of the assets is considered in the calculation of energy and water intensity, except in those cases where MERLIN only has control over the management of consumption in the common areas, in which case only the surface area of these common areas is considered.
