Background

The Acid Deposition Monitoring Network in East Asia (EANET) was established in 2001 as a regional intergovernmental network to promote cooperation among countries in East Asia to address acid deposition problems. In 2021, at the Twenty-Second Session of the Intergovernmental Meeting (IG22), the 13 Participating Countries of the EANET agreed to expand its scope to address wider air pollution problems and launched the EANET Project Fund to encourage cooperation with partners outside of its network.

In the last 20 years, the EANET has made excellent progress in acid deposition monitoring cooperation, including on particulate matter, sulfur dioxide, nitrogen dioxide, and ozone. The Network has fostered a regional monitoring network and scientific exchange platforms which have contributed to solving acid deposition and air pollution problems in East Asia.

In November 2024, the Twenty-sixth Intergovernmental Meeting (IG26) on the EANET approved the Work Programme and Budget of the EANET Core Activities in 2025, including Activity 10: Promotion of public awareness on acid deposition, including other priority chemical species, etc.

In this respect, and in line with the efforts to facilitate the sharing of a common understanding on air quality issues, the EANET Regional Awareness Workshop in 2025: “Next-Generation Air Quality Monitoring: Technologies, Communities, and Governance for Clean Air”  will be organized on Wednesday 26 November in Bangkok , Thailand, and in a hybrid format as part of UNEP’s Clean Air Week 2025, from 24-28 November 2028, at the Sukosol Hotel in Bangkok, Thailand.

Short Description

Air pollution remains the single largest environmental health risk worldwide, with Asia experiencing the most severe impacts. Effective air quality management requires robust, reliable, and inclusive monitoring systems that integrate scientific innovation, community participation, and policy action. While governments and research institutions have traditionally relied on reference-grade monitoring, new technologies—including low-cost sensors, satellite monitoring, artificial intelligence (AI), and open-source toolkits—are reshaping the landscape of air quality management.

Objective and Participants

This session explores how innovative approaches are enabling more accessible, hyperlocal, and transparent data generation and governance. It brings together leading experts, civil society, academia to share lessons from on-the-ground experiences, advanced modelling approaches, community-led initiatives, and legal innovations such as the Pollution Release and Transfer Register (PRTR) bill in Thailand.

The discussion will focus on:

• Pathways to integrate innovative monitoring into governance frameworks for cleaner air
• How new technologies and open-source tools can strengthen monitoring and data transparency.
• The role of numerical models, AI, and satellite data in supporting decision-making at the local, national and regional scale.
• How community engagement and right-to-know legislation can empower citizens.

Expected in-person and online participants will include the EANET National Focal Points, Scientific Advisory Committee members, and other EANET members and partners, including policymakers, national researchers, and scientists. It will also welcome representatives of partner organizations working on related issues, as well as participants joining the Clean Air Week.
