Environmental sub models for a macroeconomic model: Agricultural contribution to climate change and acidification in Denmark

Environmental sub-models are developed for agriculture-related emissions of CH4, N2O and NH3. Agricultural emission sources related to the production specific activity variables are mapped and emission dependent parameters are identified in order to calculate emission coefficients. The emission coefficients are linked to the economic activity variables of the Danish agricultural production. The model system is demonstrated by projections of agriculture-related emissions in Denmark under two alternative sets of assumptions: a baseline projection of the general economic development and a policy scenario for changes in the husbandry sector within the agricultural sector.
