Acquisition and development of methods, activity data and emission factors for the climate reporting under LULUCF/AFOLU

Drained peatlands account for 2-5% of the total German greenhouse gas emissions. Thus, they are the largest single source besides the energy sector and need to be reported in the national greenhouse gas inventories with country-specific emission factors depending on climate region, soil type and land use as well as with a complete set of activity data (e.g. management, soil type or groundwater level).  Currently, this is not yet possible as emission factors for a number of important land use and soil types are missing. Furthermore, there is no area specific data on land use and hydrology.

Thus, the Thünen Institute funds a large joint research project (2009-2012), which is coordinated by Dr. Matthias Drösler (Hochschule Weihenstephan-Triesdorf).

Duration: 3.2009 - 12.2012

Project status: finished
