Greenhouse Gas Emissions from Peat Extraction in the Center of the European Part of Russia

The carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) fluxes measured at a peat extraction site in the Moscow region in different seasons of 2005-2015 are considered. The average daily (taking into account intradaily dynamics) and average annual fluxes (emission factors) of CO2, CH4, and N2O from the interditch spacing (including microscale elevations and depressions) and drainage channels were estimated. The values of CO2 and N2O fluxes from the main interditch surface were equal to 3.3 t C-CO2/(ha year) and 1.1 kg N-N2O/(ha year), respectively; the value of the CH4 flux from the channel was 3200 kg CH4/(ha year). The resulting estimates are consistent with the default emission factors proposed for the "peatland under extraction" land category by the 2013 Supplement to the IPCC 2006 Guidelines for National Greenhouse Gas Inventories: Wetlands. The results can be used for preparing the national report of the Russian Federation on the emission and absorption of greenhouse gases not controlled by the Montreal Protocol.
