Figur 2.7 Utsläpp av växthusgaser i produktionen av ett kg Radiative Forcing som mätmetod, istället för Global Warming Potential (GWP). 3 Enligt Couwenberg (2009) är bidraget av CH4 och N2O mätt som. GWP, vid CO2, CH4 och N2O och därefter omvandlats till kg CO2e/MJ genom GWP för CH4 och N2O. (Naturvårdsverket, 2020).

The equation to calculate GWP is:GWP ¼ F CO2−C Â 44 12 þ F CH4−C Â 16 12 Â RF CH4 þ F N 2O−N Â 44 28 Â RF N 2Oð1ÞWhere F CO2−C , F CH4−C and F N2O−N are annual fluxes of CO 2 , CH 4 and N 2 O between terrestrial ecosystems and the atmosphere based on mass of C and N, respectively.

The methodology and science behind the GWP calculation can be considered one of the most accepted LCIA categories. GWP will be expressed on an equivalency basis relative to CO 2 – in kg or tonnes CO 2 equivalent. The proportion of GWP CO2, GWP CH4 and GWP N2O ’s contribution (%) to net GWP was 13.8 to 26.5, 71.9 to 86.1 and 0.13 to 1.61, respectively. This indicates that CH 4 was a major contributor to GWP in the paddy field and was governed by management practices especially residue and water regimes.

farmers used to grow it, which met a lot of the greenhouse gas nitrous oxide. The byproduct of this

Ogni valore di GWP è calcolato per uno specifico intervallo di tempo (in genere 20, 100 o 500 anni).

Although controlled irrigation is one of 1 Oct 2005 Tropical peatlands are important sources and sinks of atmospheric methane ( CH4) and ma- jor sources of carbon dioxide (CO2) and nitrous Main greenhouse gases with global warming potential. Likewise, methane is responsible for a large portion of recent warming despite having a GWP much The global warming potential (GWP) of each gas is illustrated in the Table 1.
