The attribution of greenhouse gas (GHG) emissions embedded in interregionally traded products to either production or consumption regions is a key issue to the understanding of the global environmental responsibility of metropolitan areas. In this paper we identify GHG emissions for which metropolitan areas assume responsibility by allocating emissions embodied in import and export products to regions of either consumption or production in the cases of three US metropolitan areas. The case studies show that embodied emissions in both export and import products accounted for 63-73% of total GHG emissions directly and indirectly pertaining to these metropolitan economies. These findings suggest that an accounting method that incorporates emissions embodied in product trade has relevance to the development of local policies that govern actions ranging from redirecting metropolitan development patterns toward low carbon emissions to promoting sustainable consumption behavior, particularly those involving the collaboration of cities.
