They are also used as inputs into dispersion models to predict pollutant concentrations. Several emissions inventories have been compiled in the UK for the major urban conurbations. They use locally available data, and provide emissions data that can be investigated and scenarios to be tested at a local level. The UK also has a national emissions inventory, produced using national data, ge
