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 ...

Jan 16, 2025 · 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 time period usually used for GWPs is 100 years.

Apr 2, 2009 · Sulfur dioxide (SO 2) is the most voluminous chemically active gas emitted by volcanoes and is readily oxidized to sulfuric acid normally within weeks. But trace amounts of SO 2 exert significant influence on climate.

EPA’s national ambient air quality standards for SO2 are designed to protect against exposure to the entire group of sulfur oxides (SOx). SO2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SOx).

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 ...

The Global Warming Potential (GWP) metric examines each greenhouse gas’s ability to trap heat in the atmosphere compared to carbon dioxide (CO 2). We measure this over a specified time horizon. Often, we calculate GHG emissions in terms of how much CO 2 is essential to produce a similar warming effect over the chosen time horizon.

Global Warming Potential, or GWP. Each greenhouse gas has active radiative, or heat-trapping properties. To compare greenhouse gases, they are indexed according to their Global Warming Potential. GWP is the ability of a GHG to trap heat in the atmosphere relative to an equal amount of carbon dioxide.

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.
