WebFeb 12, 2024 · The IPCC’s 1995 report, for example, put methane’s 100-year GWP at 21. The GWP of methane increased by about 20 percent between the IPCC’s fourth and fifth assessment report, when the IPCC first included multiple feedbacks in the atmosphere that can cause methane to produce other gases that trap heat, like ozone and water vapor. millbrook court

The second step is to multiply the tonnes of methane by the GWP for 2024–21. From the table above, the GWP used for methane in 2024–21 is 28. Therefore, 4,000 tonnes of methane multiplied by 28 results in 112,000 t CO 2 -e of methane.
