Air pollution has been a long-standing global issue because of its adverse effects on air quality, climate, and health. Exposure to air pollution is the 4th leading cause of premature deaths in the world, and 91% of the world population is exposed to concentrations above the guidelines set by the World Health Organization (WHO), especially in developing countries in Asia. One of the steps in managing air quality is the conduct of an emissions inventory (EI) which lists all emission sources in a geographical area and their respective contribution to air pollution. The EI results provide quantified values of where pollution comes from, providing a data-driven approach to developing policies that can control emission sources.

The estimated contribution of the transport sector to air pollution in Asian cities is greater than the global average. This is supported by the global source apportionment of PM2.5  where traffic is among the top three sources in East Asia (excluding China), South Asia, and Southeast Asia. In developing an EI for mobile sources, priority measures to address emissions from specific types of vehicles, fuel, and the engine can be developed. Data from the EI can provide baseline information that is crucial in tracking improvements in air quality due to emission reduction measures.

The Acid Deposition Monitoring Network in East Asia (EANET) is organizing this workshop on emission inventory development for management of emissions from the transport sector on 23 November 2022 in collaboration with Clean Air Asia. The Network Center for EANET, with Clean Air Asia, has carried out capacity building activities such as development of the Guidance Framework of Air Pollution and development of Emission Inventory Manual in Mongolia. 

TRAINING OBJECTIVES

The objective of this training is to help government officials and policy/decision makers understand the role of emission inventory in air quality management, particularly in the transport sector. The specific objectives are the following:

  • To provide an overview of how emission inventories are done and discuss the role of an emission inventory in air quality management
  • To strengthen the capacity pof government officials and policymakers in interpreting and utilizing the data from emission inventories
  • To share the lessons learned from different cities that have used emission inventories in implementing reduction measures in their region
