The Second Meeting of the EANET Project on Emissions Inventories and Source Apportionment of Air Pollution in Southeast Asia
Following a first kick-off meeting organized in April 2024, this second meeting of this project aimed to share updates on emissions inventories (EI) and source apportionment (SA) studies across Southeast Asia, which are crucial for understanding and managing air pollution in the region.
Representatives from government agencies, academic institutions, and international organizations including the Ministry of Environment, Cambodia; the Institute of Global Climate and Ecology (IGCE), Russia; the French Centre Interprofessionnel Technique d’Etudes de la Pollution Atmosphérique (CITEPA); Clean Air Asia (CAA); the Bandung Institute of Technology (ITB), Indonesia; the Universiti Kebangsaan Malaysia (UKM); King Mongkut’s University of Technology Thonburi (JGSEE-KMUTT); the Asia Center For Air Pollution Research (ACAP) and the Children and Youth Major Group to UNEP (CYMG) joined the meeting. Participants discussed the current state of EI and SA, identified challenges, and explored potential solutions for harmonizing data collection and methodology.

Assessing Emissions Inventories and Source Apportionment Capabilities and Data in Southeast Asia
Mr. Bert Fabian, EANET Coordinator, opened the session by emphasizing the project’s significance, which seeks to compile and assess EI and SA studies to support policy formulation in Southeast Asia. Dr. R. L. Verma from RRC.AP presented a survey-based assessment of institutional capabilities in the region. His findings revealed that while most countries have designated agencies for EI, there are significant gaps in specific regulations and resources. Dr. Truong Thi Huyen from AIT presented updates on the analytical framework for assessing EI and SA development in Southeast Asian countries, highlighting key findings, compilation strategies, and the next steps with an expected timeframe.
A key takeaway from the discussions was the necessity for a harmonized approach to developing and sharing EI and SA data. Participants highlighted the role of governments in overseeing data collection and ensuring its accessibility. They also noted the importance of local emission factors and the involvement of academic institutions in developing these factors.

Harmonizing the Emission Inventories and Source Apportionment methodologies and data collection
The meeting featured two panel discussions. The first panel focused on experiences from EANET Participating Countries, while the second addressed challenges in harmonizing EI and SA methodologies and data collection. Experts from various organizations shared insights on engaging government participation, ensuring data quality, and formulating effective policies. The project meeting underscored the critical need for regional cooperation and effective data management to tackle air pollution challenges in Southeast Asia.
In his closing remarks, Mr. Fabian thanked the participants for their active engagement and emphasized the next steps, including further collaboration and capacity building to address air pollution in Southeast Asia.
The project Stocktaking and Methodological Assessment of Emissions Inventories and Source Apportionment of Air Pollution in Southeast Asia is being conducted with the support of the EANET Project Fund.
