A network project run has gathered researchers in the field of Life Cycle Assessment (LCA) and seafood to discuss and develop methodology for LCAs of seafood products.Project participants represented national projects in this field in Finland, Sweden, Denmark, Norway and Iceland. The project has resulted in exchange of research results between the national projects and has constituted a forum for discussion of methodological issues for the participants. Methodological development has taken several important steps forward through this collaboration which are reported in this report as well as benefits of this development for the Nordic seafood sector.The report starts with a brief introduction to LCA methodology, continues with short reports about important environmental questions related to fishery and reports from the different workshops. Finally, a discussion of results, conclusions and a future outlook ends the report. Hopefully this will give a good picture of the status of LCA methodology for products coming from fishery and aquaculture.
