Drained peatlands are significant hotspots of carbon dioxide (CO2)emissions and may also be more vulnerable to fire with its associated gaseous emissions. Under the United Nations FrameworkConvention on Climate Change (UNFCCC) and the Kyoto Protocol, greenhouse gas(GHG) emissions from peatlands managed for extraction are reported on anannual basis. However, the Tier 1 (default) emission factors (EFs) providedin the IPCC 2013 Wetlands Supplement for this land use category may not berepresentative in all cases and countries are encouraged to move tohigher-tier reporting levels with reduced uncertainty levels based oncountry- or regional-specific data. In this study, we quantified (1)CO2-C emissions from nine peat extraction sites in the Republic ofIreland and the United Kingdom, which were initially disaggregated by landuse type (industrial versus domestic peat extraction), and (2) a range ofGHGs that are released to the atmosphere with the burning of peat.Drainage-related methane (CH4) and nitrous oxide (N2O) emissions aswell as CO2-C emissions associated with the off-site decomposition ofhorticultural peat were not included here. Our results show that netCO2-C emissions were strongly controlled by soil temperature at theindustrial sites (bare peat) and by soil temperature and leaf area index atthe vegetated domestic sites. Our derived EFs of 1.70 (±0.47) and 1.64(±0.44) t CO2-C ha−1 yr−1 for the industrial anddomestic sites respectively are considerably lower than the Tier 1 EF(2.8 ± 1.7 t CO2-C ha−1 yr−1) provided in theWetlands Supplement. We propose that the difference between our derivedvalues and the Wetlands Supplement value is due to differences in peatquality and, consequently, decomposition rates. Emissions from burning of thepeat (g kg−1 dry fuel burned) were estimated to be approximately 1346CO2, 8.35 methane (CH4), 218 carbon monoxide (CO), 1.53 ethane(C2H6), 1.74 ethylene (C2H4), 0.60 methanol (CH3OH),2.21 hydrogen cyanide (HCN) and 0.73 ammonia (NH3), and this emphasisesthe importance of understanding the full suite of trace gas emissions frombiomass burning. Our results highlight the importance of generating reliableTier 2 values for different regions and land use categories. Furthermore,given that the IPCC Tier 1 EF was only based on 20 sites (all from Canada andFennoscandia), we suggest that data from another 9 sites significantly expandthe global data set, as well as adding a new region
