Emission inventories that include spatially explicit emission estimates facilitate the accurate tracking of emission changes, identication of emission sources, and formulation of policies for climate-change mitigation. Many currently available gridded emission estimates are based on the disaggregation of country- or state-wide emission estimates, which may be useful in describing city-wide emissions but are of limited value in tracking changes at subnational levels. Urban GHG emissions should therefore be quantied with a true bottom-up approach. Results: Multi-resolution, spatially explicit estimates of fossil-fuel carbon dioxide (FFCO2) emissions from the Tokyo Metropolis, Japan, were derived. Spatially explicit emission data were collected for point (e.g., power plants and waste incinerators), line (mostly trac), and area (e.g., residential and commercial areas) sources.
