 +==== Methodology ====
  
 For calculating the emissions of wildfires a country specific Tier2 approach was used. The mass of carbon emitted M(C) was calculated using the adapted equation follows the methodology of Seiler and Crutzen (1980) ((Seiler, Wolfgang, and Paul J. Crutzen. "Estimates of gross and net fluxes of carbon between the biosphere and the atmosphere from biomass burning." Climatic change 2.3 (1980): 207-247.)).  For calculating the emissions of wildfires a country specific Tier2 approach was used.

-For the calculation of CO emissions the EF according to Table 2.7, 2013 IPCC Wetlands Supplement 207 g (kg dm)-1, is taken into account. This results in 85 kt CO. For other emissions from land fires on drained organic soils no Tier-1 emission factors exist and are therefore not reported (NO)".+For the calculation of CO emissions the EF according to Table 2.7, 2013 IPCC Wetlands Supplement 207 g (kg dm)<sup>-1</sup>, is taken into account.
