ESG SDDS Wiring-Guide

Actual scope 3 emissions are calculated as the emissions associated with tenant areas. The term 'actual' refers to scope 3 emissions that are not estimated. Scope 3 emissions do not include embodied carbon as it is a separate recommended indicator of INREV framework. Scope 3 emissions cover only operational activities of the portfolio of the vehicle and do not include emissions generated through the organisation’s operations or by its employees, or upstream supply chain emissions (ref: GRESB). Reference the methodology used to calculate GHG emissions in the comment box.
 

"This indicator covers actual Scope 3 emissions from operational energy use in areas where tenants have operational control (see ESG3.1.1). These emissions are indirect, as they occur outside the direct control of the reporting vehicle but are linked to the operational performance of its assets.
Report only actual data derived from verifiable sources such as tenant utility invoices, sub-meter readings, or smart meter outputs. If only estimated data is available, report under ESG3.3.8.

Emission factors should be consistent with those used for Scope 1 and Scope 2 reporting and sourced from credible datasets (e.g. IPCC, IEA, DEFRA, GHG Protocol).

Embodied carbon is excluded from this indicator and should be reported separately under ESG4.3 (recommended).

This indicator is one of the six environmental factors considered most relevant for underwriting (see INREV (2025) Integrating environmental considerations in real estate underwriting paper)."
 

"Note 1: For tenant-purchased electricity, location-based reporting should be the minimum approach. Market-based reporting is optional under the GHG Protocol. Where both methods are available, disclose them separately and specify the source of contractual instruments or residual mix factors.

Note 2: If tenant energy use is sub-metered or reported through green leases/voluntary disclosure, include these emissions and state the calculation method used.

Note 3: This indicator aligns with the GHG Protocol Category 13 – Downstream Leased Assets, which covers emissions from the operation of assets owned by the reporting vehicle but controlled by tenants (e.g. tenant areas with their own energy supply or metering). In the GRESB Assessment, Scope 3 emissions are calculated as those associated with tenant-controlled areas unless already reported under Scope 1 or Scope 2 (where landlord and tenant emissions cannot be disaggregated). Scope 3 emissions do not include embodied carbon, corporate operations, employee activities, transmission losses, or upstream supply chain emissions."
