The project developed Singapore's national emissions inventory and subsequently calibrated the ADMS Urban Model to better understand Singapore's urban air quality. The model was calibrated against the nations continuous air quality monitoring stations and proved to be accurate acorss the criteria pollutants.  In subsequent phases ESC trained the NEAs technicians in the upkeep of the emissions database and on how to run the model to analyse ‘what if' scenarios to enable the planning of improvements to its urban air quality via implementation of policies to enable sustainable infrastructure planning.
