This paper describes the conceptual framework for a damage value-oriented weighting method for endpoint problems. It is developed with the aim to be transparent, and with a minimum of subjective features. Calculations of external environmental impacts are based on data for material- and energy flows, emission factors, and characterisation of emissions into contribution to environmental impact categories. These environmental impact values are then weighted by using damage values (total number of DALY (Disability Adjusted Life Years)) for each type of problem. Estimations of the number of persons possibly affected by a problem caused by emissions have been made and multiplied by the severity for each affected person. The category weight is the sum of all damage values in an impact category. This approach has several advantages: (1) A clear distinction between the characterization step and valuation step of the LCA, (2) A knowledge driven method where an improvement in quality and reliability of information and data used can be easily introduced to the framework. The method also suffers from some disadvantages: (1) As in other weighting methods, forecasts about the future in terms of scenarios do always mean an uncertainty and (2) Local and regional environmental problems are extrapolated to global effects, which means that uncertainties are introduced.
