 Abstract: The objective of this study was to show how and why socio-economic analysis and emergy analysis provide different information to support decision-making. Also, by applying the emergy method, the ability of willow agriculture to provide energy in the form of combined heat and power (CHP) was examined with respect to renewability and efficient use of natural and human resources.Literature studies were used to gain an understanding of the theoretical foundations of both assessment methods. Also, access to an economic model of growing willow in Danish agriculture made it possible to assess assumptions and results of a socio-economic analysis of cost-effective reductions of CO2-emissions from Danish agriculture. Finally, an emergy analysis of production, transport and large-scale combustion of willow for bio-energy under Danish conditions was performed. The emergy case study led to conclusions concerning sustainability and energy conversion efficiency and it allowed for identification of central aspects of emergy accounting.It was found that socio-economic analysis applies an anthropocentric value system based on human preferences that is unable to objectively assign value to ecosystem services, including natural resources. Emergy accounting bases valuation of resources on an ecocentric value system and is able to account for the level of environmental support as well as support from the human economic system. Results of the emergy study revealed that willow should not be considered an energy source; producing CHP from willow is dependent on large inputs of fuels and materials; heat and power output of the considered system was found to be sixteen percent renewable. It was indicated that emergy accounting can benefit from clear guidelines concerning scope, required inputs, and practical procedures to deal with co-products.Decisions on how to utilise natural resources should not be based on economic assessments alone. Economic theory is not able to adequately account for the contributions of environmental systems. In order for human behaviour to be compatible with ecosystem behaviour, long-term planning of natural resource use should be based on assessments that account for all inputs in a life-cycle perspective, not only on monetary flows in the human economy.
