Guidance Framework for Better Air Quality in Asian Cities - Emissions inventory and modelling

This guidance area addresses the issues of developing an accurate and reliable emissions inventory (EI) which can be used as input to dispersion models in order to estimate exposure of human populations and the environment. Information from EIs are also important for understanding air pollution sources to draw up control measures to mitigate industrial, transport, and residential emissions and achieve compliance with emission standards. Source apportionment (SA) is a science-based approach to assess the contribution of emissions of specific source types to air pollutant concentrations at receptor sites. The guidance area also discusses the issues and challenges in Asian cities and regions and develops a roadmap and recommendations on how to implement effective approaches to resolve the challenges.
