WebParties to use 100-year GWP values from the IPCC Fifth Assessment Report (AR5) for calculating CO 2-equivalence in their national reporting (IPCC 2013) by the end of 2024. In preparation for upcoming UNFCCC requirements2, this report reflects CO 2-equivalent greenhouse gas totals using 100-year AR5 GWP values. The use of AR5 GWP values WebEach greenhouse gas (GHG) has a global warming potential value, which reflects the climate forcing of a kilogram of emissions relative to the same mass of carbon dioxide (CO2). This number is calculated by the Intergovernmental Panel on Climate Change (IPCC), based on the intensity of infrared absorption by each GHG and how long …

Web12 feb. 2024 · 1. Note that here the EPA used values from the IPCC’s 4th Assessment Report (AR4), which gives methane a GWP of 25. The current understanding of methane’s GWP is 34, so the sentence reflects EPA’s number as a minimum rather than an equivalent. These EPA figures are also based on a 100-year global warming potential for methane. ↩ WebIPCC Data The Task Group on Data Support for Climate Change Assessments aims to provide guidance to the IPCC’s Data Distribution Centre on curation, traceability, …
