This document provides 100-year time horizon global warming potential (GWP) values from the Intergovernmental Panel on Climate Change (IPCC). The table below is adapted from the IPCC Sixth

The global warming potential (GWP) is defined as an "index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, carbon dioxide (CO 2). The GWP thus represents the combined effect of the differing times these substances ...

2025年1月16日 · Specifically, the GWP is a measure of how much energy the emission of 1 ton of a gas will absorb over a given period of time, relative to the emission of 1 ton of carbon dioxide (CO 2). The larger the GWP, the more that a given gas warms the Earth compared to CO 2 over that time period.

The following table includes the 100-year time horizon global warming potentials (GWP) relative to CO2. This table is adapted from the IPCC Fifth Assessment Report, 2014 (AR5)i.

Each 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 (CO 2). 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 emissions ...

2020年9月9日 · CO 2, by definition, has a GWP of 1 regardless of the time period used, because it is the gas being used as the reference. CO 2 remains in the climate system for a very long time: CO 2 emissions cause increases in atmospheric concentrations of …

Climate metrics (e.g. GWP and CO2e) help to compare or combine the emissions of pollutants according to their impact on the global climate. GWP and the related CO2e are the most common climate metrics used for climate analysis and policy.

2 天之前 · The Global Warming Potential-star (GWP*) approach is a way to convert the emissions of short-lived climate forcers to CO2-equivalent emissions while maintaining consistency with temperature outcomes.

2023年11月6日 · Global warming potential (GWP) values are used to convert greenhouse gases into a carbon dioxide equivalent metric by multiplying emissions in mass terms by their respective GWP factors. For example, a GWP value of 25 for a certain gas means that one tonne of that ags has 25 times the warming impact of one tonne of carbon dioxide.
