Table 1. Carbon emissions from fires. Average value ± SE of fuel load (FL), combustion completeness (CC), burned areas (detailed as burned on mineral soils + peat soils for each vegetation cover defined in Fig. 3), emission of carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄), nitrous oxide (N₂O), mono-nitrogen oxides (NOx), total carbon (C) emission (CO₂+CO+CH₄) and total emission of greenhouse gases (GHG) (CO₂+CH₄+N₂O). Total emission of GHG were calculated using 20 (GHG_20YGWP) and 100 year (GHG_100YGWP) global warming potentials (GWP) for CH₄ and N₂O. The lack of appropriate emission factors for other GHG species prevented their inclusion.
