      abstract     = {We examine the representation of emissions from megacities
                      in three global anthropogenic emission inventories. Despite
                      the many common sources of data between the inventories, and
                      the similarities in their construction methodologies, there
                      are some very large differences (often a factor of two)
                      between the emissions for individual cities, even when the
                      total global emissions are very similar. We find that the
                      geographical distribution of the emissions within countries
                      plays a larger role in explaining the differences between
                      the inventories than differences in the country total
                      emissions. We also find very large differences between the
                      contribution of various sectors to the total emissions from
                      each city, and relate these differences to the respective
                      methodologies used in the inventory construction. By and
                      large, in OECD countries megacity emissions from the global
                      inventories are dominated by road transport, especially for
                      CO and to a lesser degree for NO,. In non-OECD countries,
                      notably in Asia, megacity CO emissions are dominated by
                      residential biofuel use, while industrial emissions
                      predominate for NO,. Non-methane hydrocarbon emissions in
                      OECD megacities are caused by industry and traffic, whereas
                      in non-OECD countries residential biofuel use makes
                      significant contributions. These emission signatures often
                      result from assumptions about the distribution of emissions
                      according to gridded population density maps rather than
                      according to the actual location of the emitting processes.
                      We recommend the use of an ensemble of inventories, that the
                      geographical distribution of emissions receives increased
                      attention, and that local inventories be integrated into
                      global emission inventories. (C) 2007 Published by Elsevier
