The Swedish Armed Forces (SAF) and the Defence Materiel Administration (FMV) shall take environmental consideration in all phases of the acquisition process, according to a decision made by the Swedish government in 1998. Environmental consideration in public procurement (such as defence acquisition) is somewhat different from non-public organisations, depending on differences in regulating laws and regulations. This report includes a description of the actors, the regulating documents and the Swedish acquisition of defence materiel. The process is today under development and is therefore briefly described. The importance to take environmental consideration in a life cycle perspective has been stressed by both SAF and FMV. This report has the aim to describe how this can be done. Our major suggestion is that the defence sector should work systematically through different product groups. For each product group, traditional LCAs combined with simplified LCAs (in this case MECOs) or stand-alone simplified LCAs should be performed for reference products, within each product group. The results should be an identification of critical aspects in the life cycles of the products. This knowledge should then be used when writing TTEMs (Tactical Technical Economic Goals) and setting criteria for procurement.
