Update and improvement of GAS-EM modules for calculating emissions from animal husbandry

Haenel, Hans-Dieter GND; Rösemann, Claus GND

•The Thünen Institute of Climate-Smart Agriculture uses the GAS-EM model to calculate emissions of greenhouse gases, air pollutants and particulate matter from agriculture for the annual German emission inventories.•The GAS-EM modules for dairy cows, calves, heifers and male beef cattle have been updated regarding calculation of energy requirements and feed intake to take into account improved data availability and developments in animal husbandry practice.•The updated modules mainly calculate lower animal excretions and thus lower emissions of greenhouse gases and ammonia from German animal husbandry.
