Abstract

Development of an emission inventory (EI) is building up a complex and comprehensive dataset to provide useful information for air quality management (AQM) and assessment of greenhouse gas mitigation options. This chapter highlights necessary steps of EI process and emphasizes the quality assurance and quality control procedure required to minimize the uncertainty of EI estimates. The EI is an important activity in AQM. Based on EI results, key pollutants of concern and their key sources could be identified; thereby, the source emission control efforts can be prioritized to reduce air pollution in the domain. Data computing and management through cloud system could potentially help to facilitate the storage and flows of an intensive amount of EI information. The chapter also illustrates with examples of EI databases developed by the authors for various domains, ranging from the whole Southeast Asia region to national and urban scales.
