About SEFR
The Singapore Emission Factors Registry (SEFR) is a collaborative initiative led by the Singapore Business Federation (SBF) in partnership with government agencies and industry stakeholders. It consolidates emission factors across various sectors to assist businesses in accurately calculating their greenhouse gas emissions.

| 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. |

EXIOBASE
EXIOBASE is a global, detailed Multi-Regional Environmentally Extended Supply-Use Table (MR-SUT) and Input-Output Table (MR-IOT). It was developed by harmonising and detailing supply-use tables for a large number of countries, estimating emissions and resource extractions by industry. Subsequently, the country supply-use tables were linked via trade creating an MR-SUT and producing MR-IOTs from this. The MR-IOT can be used for the analysis of the environmental impacts associated with the final consumption of product groups. The EXIOBASE emission factors use basic prices. The basic price represents the initial cost set by a producer for a product or service, without additional fees like taxes or delivery costs (referred to as tax and transport margins). The values in the Climatiq Database might not be exactly the same as the ones you find on the EXIOBASE download page due to the prices used.
