Calculations of gaseous and particulate emissions from German agriculture 1990 - 2012 : Report on methods and data (RMD) Submission 2014

The report at hand (including a comprehensive annex of data) serves as additional document to the National Inventory Report (NIR) on the German green house gas emissions and the Informative Inventory Report (IIR) on the German emissions of air pollutants (especially ammonia). The report documents the calculation methods used in the German agricultural inventory model GAS-EM as well as input data, emission results and uncertainties of the emission reporting submission 2014 for the years 1990 - 2012. In this context the sector Agriculture comprises the emissions from animal husbandry and the use of agricultural soils. As required by the guidelines, emissions from activities preceding agriculture, from the use of energy and from land use change are reported elsewhere in the national inventories. The calculation methods are based in principle on international guidelines for emission reporting and have been continuingly improved during the past years. This concerns especially the calculation of energy requirements, feeding and the N balance of the most important animal categories. In addition, technical mitigation measures such as air scrubbing and digestion of slurry have been taken into account. [...]

Minderung der CO2-Emissionen durch effizienten Energieeinsatz im Unterglasgartenbau

Depending on the technology used, the operational system and the crop being grown, around 500000 kWh heating energy per year is required for a 1000 m2 ground area greenhouse. Reducing heat losses from such buildings is very important for increasing energy efficiency through less energy costs and carbon dioxide emissions. The installation of an energy shield is very efficient in this respect, offering energy savings of approx. 25 %. Further energy savings can be achieved with two-layer greenhouse walls and roof. Combining technical and management measures heating energy requirement for a 1000 m2 greenhouse can be reduced by up to 60 %. This could mean an around 124 t reduction in annual carbon dioxide emissions from a Venlo greenhouse with oil-fired heating. In that some of these energy saving actions also save operating costs, negative carbon dioxide reduction costs are achieved in most variants.
