Towards new reporting of drained organic soils under the UNFCCC : assessment of emission factors and areas in Sweden

Lindgren, Amelie; Lundblad, Mattias

Sammanfattning

The 2013 Supplement to the 2006 Guidelines for National Greenhouse Gas Inventories: Wetlands (Wetlands Supplement), hereafter called WL GL, was adopted and accepted at the 37th Session of the IPCC in October 2013. This study assesses how to adapt the WL GL for Swedish conditions and available data sources. This includes both the assessment of emission factors and the possibility to obtain relevant activity data for the categories included in the WL GL. The report focuses on land use categories in the Land use, Land use change and Forestry sector (LULUCF) where emissions from drained organic soils occur, and the rewetting of these organic soils. Table 2 summarizes the recommended emission factors described throughout the sections in this report, and the total impact of the new emission factors on the emissions from a land-use area (IEF). See relevant sections for discussion on the choice of emission factors. The emission factors presented here are only representative for land remaining within a category and not for land use change between categories, except rewetting. These results show that drained organic Cropland has the highest impact per area. Swedish Forest land contributes with the highest CO2 -eq emissions due to the large area. The total emissions from the land-use categories described in table 2 are 10.63 Mt CO2 eq.
