The document discusses material flow management and greenhouse gas (GHG) inventorying at the regional level. It introduces concepts of regional material flow modelling (RMFM) and outlines approaches to conducting GHG inventories for regions. Tools for RMFM and GHG inventorying are examined, including their strengths and limitations. The document also presents the Institut für angewandtes Stoffstrommanagement's approach to RMFM, which involves informal data gathering, stakeholder engagement, training key actors, and conducting material flow analyses of regions.
