Singapore's Average Operating Margin (OM) Grid Emission Factor (GEF) and Build Margin (BM) Emission Factor remained relatively constant at 0.4192 kg CO2/kWh and 0.4018 kg CO2/kWh respectively in 2017. In general, Singapore's BM emission factor trends lower than the OM emission factor. This is because newer plants in Singapore (predominantly CCGTs) are more efficient and primarily use fuels with a lower carbon content (such as natural gas) compared with other fossil fuels.
