WebJun 27, 2024 · HFCs have high global warming potential (GWP), raising concern about their impacts as they become increasingly used as replacements for ozone-depleting substances (ODS), and as economic growth spurs demand for new equipment, especially in the refrigeration/AC sector. WebThis can be used to express a tonne of a greenhouse-gas emitted in CO 2 equivalent terms, in order to provide a single measure of total greenhouse-gas emissions (in CO 2-eq). The Intergovernmental Panel on Climate Change (IPCC) has indicated a GWP for methane between 84-87 when considering its impact over a 20-year timeframe (GWP20) …
Global Warming Potentials (IPCC Fourth Assessment Report)
WebApr 29, 2024 · Protect the Environment - SF 6 is the most potent greenhouse gas known. It is 22,800 times more effective at trapping infrared radiation than an equivalent amount of CO 2 and stays in the atmosphere for 3,200 years. Common Emission Sources SF 6 is used in several different industries including: electrical transmission and distribution equipment WebAnother property of greenhouse gases that is used to assess possible future impacts is their global warming potential. Quantifying radiative forcing and GWP depends on the infrared spectra of greenhouse gases, so infrared spectroscopy has a central role in climate science research. cable and fiber optic broadband

In the most recent report by the Intergovernmental Panel on Climate Change (IPCC), multiple methods of calculating GWPs were presented based on how to account for the influence of future warming on the carbon cycle. For this Web page, we are presenting the range of the lowest to the highest values … See more EPA and other organizations will update the GWP values they use occasionally. This change can be due to updated scientific estimates of the energy absorption or lifetime of the gases or to changing … See more Data collected by EPA's Greenhouse Gas Reporting Program is used in the Inventory, so the Reporting Program generally uses GWP values from the AR4. The Reporting Program collects data about some industrial … See more The EPA considers the GWP estimates presented in the most recent IPCC scientific assessment to reflect the state of the science. In science communications, the EPA will refer to … See more The EPA's Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory) complies with international GHG reporting standards under the … See more WebBelow is a list of some greenhouse gases and their Global Warming Potential. The data below comes from the US Environmental Protection Agency: CO 2: PWG = 1. Methane (CH 4): PWG = from 28 to 36. Nitrous … WebGWPs are calculated using a set time horizon. All GWPs used for GHG inventory purposes are considered over a 100-yr timeframe. GWPs are updated periodically with … club sandwich layers
