ESG SDDS Wiring-Guide

Report the total operational carbon footprint for the reporting year by aggregating all relevant Scope 1 (ESG3.3/3.3.6), Scope 2 location-based (ESG3.3.2/3.3.7), and Scope 3 (ESG3.3.4/3.3.8) emissions.

Ensure consistency of boundaries, coverage, and reporting periods across all scopes before aggregation.

For energy-derived emissions, the operational-carbon boundary should follow the boundary applied to the underlying operational-energy indicators. Where an energy load is excluded from operational energy, its associated emissions should also be excluded from operational carbon or disclosed separately. Non-energy Scope 1 emissions, such as fugitive refrigerants, should be included where they fall within the reporting entity’s operational-control boundary and are reported under ESG3.3 or ESG3.3.6.

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: If data coverage is partial or any scope is excluded, explain the reason and its potential impact on results.

Note 2: For acquisitions and disposals, apply the same reporting-period treatment across floor area, energy and emissions (see ESG1.6). Under the GHG Protocol, significant acquisitions and disposals are structural changes that may trigger recalculation of base-year emissions under the reporting entity’s established base-year recalculation policy. This ESG SDDS guidance addresses the treatment of acquisitions and disposals within the reporting-period portfolio boundary and does not replace any applicable GHG Protocol base-year recalculation requirements.
