EANET continued to strengthen its Core and Project Activities under the current Medium-Term Plan (MTP) 2021–2025, advancing both its scientific and collaborative agenda.

Key highlights in 2025 included the organization of National Awareness Workshops in Lao PDR, and Mongolia, conducted in partnership with ESCAP’s Clean Air for Sustainable ASEAN (CASA) Project and the Northeast Asia Clean Air Partnership (NEACAP), respectively. These workshops contributed to raising awareness and strengthening technical capacity for air pollution monitoring and management in the region.

Promotion of data sharing with regional and global partners was enhanced, including through engagement with ESCAP’s Regional Action Programme on Air Pollution (RAPAP), the Climate and Clean Air Coalition (CCAC) data sharing platforms, and the World Health Organization (WHO)’s publication Air Quality, Energy and Health: Science and Policy Summaries. Significant progress was made on the drafting of the Fifth Medium-Term Plan (2026–2030), which will guide EANET’s next phase of strategic actions.

The Network Center presented updates on dry and wet deposition monitoring, catchment-scale ecosystem studies, and nitrogen management.

Adoption of Key Scientific Reports

The SAC25 reviewed and adopted several key technical documents including:

The EANET Data Report 2024, featuring updated monitoring results on wet and dry deposition, ozone, and ecosystem impacts across 13 EANET Participating Countries.
The Report on the Inter-Laboratory Comparison (ILC) Projects 2024, confirming the analytical consistency and reliability of laboratory analyses across the network.
The Updated National Monitoring Plans (NMPs), underscoring Participating Countries’ continued commitment to harmonized methodologies and improved data quality.

Strengthening Scientific Collaboration and Innovation

The SAC25 highlighted the importance of maintaining strong quality assurance and quality control (QA/QC) systems, expanding data access, and fostering regional collaboration. The Committee endorsed the Guidelines for Establishing Hybrid Air Quality Monitoring Networks (HAQMN) and the Technical Manual for Hybrid Monitoring with Low-Cost Sensors, incorporating updates based on feedback from SAC24. These resources, developed with reference to standards from the U.S. Environmental Protection Agency (EPA), the World Meteorological Organization (WMO), and the European Commission (EC), will guide EANET countries in improving data reliability and calibration practices. EANET also continued projects on Volatile Organic Compounds (VOCs) monitoring, PM₂.₅ source identification, and nitrogen management.

Looking Ahead

Twelve Project Plans for 2026 were also reviewed, including initiatives on nitrogen deposition assessment, satellite-based air quality monitoring, sustainable agriculture for clean air, and leadership training in atmospheric environment management. Project leads interested in collaborating with the EANET through the EANET Project Fund presented their project plans during the meeting. The Project leads included the Asian Institute of Technology (AIT), Clean Air Asia, the Institute for Environment and Development (LESTARI), Universiti Kebangsaan Malaysia (UKM), the Thailand Hub of Talents, and UNEP.

The SAC25 reviewed the Draft Medium-Term Plan (MTP) (2026–2030), which will guide EANET’s work for the next five years and reaffirmed EANET’s key role as a regional scientific network supporting cooperation and data-driven policymaking to improve air quality across East Asia.

Recommendations and outcomes from SAC25 will be presented at the Twenty-seventh Session of the Intergovernmental Meeting (IG27), to be held on 27-28 November in Bangkok, Thailand, back-to-back with UNEP’s Clean Air Week.
