An understanding has developed that strategies for sustainable development must be based on unified concepts since the implementation of sector action plans that aim at reducing the environmental impact within one sector may at the same time result in an increase in another sector. The present knowledge within science and economy has not yet developed to an extent where it is possible to define and quantify sustainable development in a precise manner. However, one approach is the modelling of the interactions between economic activities and environmental pressure at a national level. In this study the objectives is to develop environmental satellite models that include substances contributing to climate change and acidification. The main focus is on modelling the environmental impact from the agriculture sector. However, other sectors contributing to the environmental impact is also included, i.e. the waste sector, transport sector and energy sector. The substances included are methane (CH4), dinitrogenoxide (N2O) and ammonia (NH3). The methodology is based on the development of emission factors for the relevant economic activities. The emission models are used to calculate the total emission in a base year and the total emissions are balanced to correlate with the official Danish emission data for the reporting obligations.
