Methodology
For emission factors under Equipment and Materials and Manufacturing, the source does not specify which IPCC Assessment Report (AR) version of GWPs was used to calculate CO2e.
Partial factor
For Electricity emission factors, the source reports values in CO2 only and does not include the impact of other GHGs.

Methodology description

Launched in April 2024, SEFR aggregates more than 200 emission factors relevant to Scope 1, 2, and 3 GHG accounting across eight categories — building equipment, building materials, fuel, greenhouse gases, land transport, purchased energy, waste, and water — consolidated from four government agencies and the Singapore Green Building Council. The registry was established to address the lack of localised emission factors for Singapore, where the use of foreign (e.g. UK or US) factors does not accurately reflect Singapore's specific energy mix, operational conditions, and infrastructure.
