A large number such environment-economic have been but only in the last few years emerged that use more sophisticated multi-region, multi-sector framework. was made possible through improvements data availability quality as well computability. We identify six major employ multi-sector, analysis order calculate embodied international trade. Results from studies reviewed demonstrate it is important explicitly consider production recipe, land energy emissions multi-directional trade model, which globally closed sectorally deeply disaggregated. Only then reliable figures indicators trade, Footprint, can be derived. also describe how enumerate resource pollution content inter-regional flows with aim illustrate an ideal modelling framework estimation Footprints. What appears absent previous applications account analytical method by Footprints should ideally estimated allows explicit problems prevent application full identification most appropriate short-cut methods transparent way.
