Emission factor summary

Emission intensity of public bus. The GHG emissions standard applied is the GHG Protocol: A Corporate Accounting and Reporting Standard. Boundaries: Use phase of the public bus (i.e. combustion and grid emissions) Retrieved from Singapore Emission Factors Registry (SEFR) database. The primary data source is Ministry of Transport (MOT) Singapore. According to the source: The public bus emissions factor is calculated based on the existing composition of LTA’s public bus fleet in 2022 which comprises primarily diesel buses and a number of e-buses and diesel hybrid buses (DHBs). As LTA transits to a 100% cleaner energy bus fleet by 2040 the public bus emissions factor will decrease. The emission factors of e-buses DHBs and diesel buses are 0.04 0.06 and 0.07 respectively.
