Lifecycle emission intensities of natural gas combusted, 2024

Notes

One tonne of methane is considered to be equivalent to 30 tonnes of CO2, based on the 100-year global warming potential (GWP100) and 82.5 tonnes of CO2 based on the 20-year global warming potential (GWP20) (IPCC, 2021: https://www.ipcc.ch/assessment-report/ar6/). Columns show the average emissions intensities of deciles of natural gas and coal combusted globally.
