Gwp 20 years

WebMethane's GWP 20 of 85 means that a ton of CH 4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO 2 over a period of 20 years. On a 100-year timescale, methane's GWP 100 is in the range of 28–34. Methane emissions are important as reducing them can buy time to tackle carbon emissions. WebShortening the currently balanced time frame of GWP s, by using 20-year GWP s measuring the warming effects over a time period of 20 years, would attach more weight to short-lived greenhouse gases. Under the …
