The aim of the study was to further develop methods that can be used to assess to what extent one scenario for future forestry is overall more sustainable, compared to other scenarios in the same area. The study will not answer which future scenario that is most sustainable. Instead, the study aims to contribute to the development of standardized and transparent methods for sustainability assessments that can be used as a common basis for future discussions among different stakeholders. The methods presented represents a framework methodology, that has to be further developed and specified, particularly concerning reference scenarios and target values. The methods are intended to be applied for large forest owners or forest owner associations as well as nation-wide assessments. The overall conclusion from this study is that the suggested methodology results in reasonable values for the different sustainability indicators and the forestry scenarios tested. The methods need further development, particularly concerning the choice of reference and preference values.
