In the absence of actual data, scope 1 emissions can be estimated based on building characteristics and publicly available data using commercial databases -see PCAF, and/or linear extrapolation could be applied -see CRREM (ref: GRESB). In case estimation is used, please specify in the comment box how the calculations were done, and which critical assumptions were made.

Definition:
Additional Guidance:
"Estimate Scope 1 emissions from direct fuel use (e.g. natural gas, oil, diesel) under operational control. Where actual consumption data is missing, apply the recognised estimation methods described in ESG3.1.3 (landlord-controlled) and ESG3.1.3.1 (tenant-controlled), ensuring consistency across the portfolio.
Emission factors should be sourced from the same credible datasets as for actual Scope 1 emissions (e.g. IPCC, IEA, DEFRA, GHG Protocol).
Note 1: Clearly document the estimation method, data sources, and assumptions to ensure transparency and comparability over time."
