In 2022, ESCAP Member States adopted a Regional Action Programme on Air Pollution, and UNEP Member States in 2024, a resolution on Promoting Regional Cooperation on Air Pollution to Improve Air Quality Globally, which both include increased cooperation and knowledge exchange on air quality through online cooperation platforms, among others. EANET’s long-standing monitoring activities are being promoted in these multilateral platforms.

What is the RAPAP Partnership and Coordination Platform?

Adopted in 2022 at the 7th session of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) Committee on Environment and Development (CED7), the Asia-Pacific Regional Action Programme on Air Pollution (RAPAP) aims to promote clean air for all in Asia and the Pacific through various action areas including air quality management, air quality monitoring and data sharing, best practices, capacity building and multilateral cooperation. In the Ministerial Declaration of the CED7, one of the RAPAP’s objectives is: “To establish an open regional platform for the exchange of information and best practices on air pollution challenges and solutions, as may be deemed necessary and appropriate by members and associate members of ESCAP”. The RAPAP Partnership and Coordination Platform was established following this Ministerial Declaration and formally launched during the Fifth Asia Pacific Clean Air Partnership (APCAP) Joint Forum in March 2025 in Yokohama, Japan.

Showcasing National Plans, multilateral mechanisms, stakeholder lists, resources, live air quality data, and events, the platform is a repository for air quality actions and tools in Asia and the Pacific. The Live Air Quality Monitoring page links to various regional and global platforms including the European Space Agency (ESA), the Air Quality Index China (AQICN), and the National Institute of Environmental Research (NIER) Republic of Korea, among others.

What is AQMx?

The 6th edition of the United Nations Environment Assembly (UNEA-6) in February and March 2024 adopted a resolution on Promoting Regional Cooperation on Air Pollution to Improve Air Quality Globally which encourages Member States to continue their efforts to improve air quality by working on national air quality programs and standards. Through this resolution, Member States requested UNEP’s Executive Director to form an air quality cooperation network to raise awareness of air pollution’s impacts and the importance of mitigation actions, supporting capacity building and collaboration. It also referred to building an updated global online platform for information-sharing and communication on air quality.

Following this, the Air Quality Management Exchange Platform – AQMx – was developed by the Climate and Clean Air Coalition (CCAC), as a component of the CCAC Clean Air Flagship, in response to the need to build capacity for air quality management worldwide and to provide tools to support governments, in line with UNEA’s resolution on Promoting Regional Cooperation on Air Pollution to Improve Air Quality Globally. The platform is mainly composed of two parts: a Resources Exchange Library and the “Curated Guidance” section which aims to, in its first stage, provide a “top 10” list of actions for air quality managers to prepare a comprehensive air quality management planning.

How is EANET monitoring data promoted?

EANET data is shared in the AQMx Resource Exchange Library where users can access the EANET monitoring page and download the EANET Data Reports.

In the RAPAP Platform, EANET is presented in the Multilateral Mechanism section of the platform which includes an overview of the EANET and various resources such as EANET data and reports.

The launch of the RAPAP and AQMx platforms reflects growing regional and global efforts to strengthen cooperation on air pollution. By promoting long-standing efforts such as EANET’s monitoring activities across multiple platforms, these frameworks not only enhance transparency and capacity building but also reinforce the collective commitment of countries to tackle air pollution and protect public health and the environment.

Bangkok, 28 March 2024

The 6th edition of the United Nations Environment Assembly (UNEA-6) took place from 26 February to 1 March 2024, at the UNEP headquarters in Nairobi, Kenya, gathering over 6,000 delegates. The Assembly adopted 15 resolutions, including a resolution on Promoting Regional Cooperation on Air Pollution to Improve Air Quality Globally.

What is UNEA?

The United Nations Environment Assembly (UNEA) was created in 2012, as an outcome of the United Nations Conference on Sustainable Development (Rio+20). UNEA is the world’s highest-level decision-making body for matters related to the environment. Usually held every two years, the Assembly includes the universal membership of 193 Member States. It sets the global environment agenda, provides policy responses to environmental challenges, and provides strategic guidance on the future direction of the United Nations Environment Programme (UNEP), in line with the 2030 Agenda for Sustainable Development. UNEA has adopted many important resolutions over the years, including a resolution in 2022 that called for a legally binding international instrument to end plastic pollution.

Taking Action to Fight Air Pollution

Recognizing that air pollution is a major threat to the environment and to human health, with more than 7 million people dying prematurely due to air pollution every year, Member States adopted a resolution 1/7 on strengthening the role of the United Nations Environment Programme (UNEP) in promoting air quality at UNEA-1 in 2014. A second resolution was adopted at UNEA-3 in December 2017 on Preventing and reducing air pollution to improve air quality globally. Following the adoption of these two resolutions, UNEP implemented numerous activities creating awareness, building capacity and partnerships. These included strengthening cooperation with existing regional and global initiatives such as the EANET, as mentioned specifically in resolution 1/7.

UNEA’s Third Resolution on Air Quality

At UNEA-6, Member States adopted 15 resolutions aiming to tackle the triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste, including the resolution on Promoting Regional Cooperation on Air Pollution to Improve Air Quality Globally.

This new resolution builds on Resolutions 1/7 and 3/8 and encourages Member States to continue their efforts to improve air quality by working on national air quality programmes and standards, bearing in mind the WHO global air quality guidelines. In addition, Member States requested UNEP’s Executive Director to form an air quality cooperation network to work with governments, UN organizations, multilateral environmental agreements (MEAs), international and regional initiatives, including the EANET. This network’s tasks will include raising awareness on air pollution’s impacts and the importance of mitigation actions, supporting capacity building, and encouraging collaboration with Member States with advanced air quality management capabilities to enhance national monitoring using low-cost sensors, satellite data, and other digital solutions, sharing knowledge, facilitating expertise exchange including on nitrogen management, and regional air quality programs, and building an updated global online platform for information-sharing and communication on air quality.

How the EANET can contribute to the implementation of this resolution

Just as in Resolution 1.7, this latest Resolution directly references the EANET and its role alongside various other key regional air quality initiatives: “Acknowledging the progress achieved by existing bodies and initiatives that facilitate cooperation on in-country and transboundary air pollution, including the UNECE Convention on Long-Range Transboundary Air Pollution (…) and the Acid Deposition Monitoring Network in East Asia”.

The EANET, as a robust regional intergovernmental body with standardized monitoring methodologies, already significantly contributes to UNEA Resolutions 1/7 and 3/8 on air quality. Since 2001, the network has developed open access high-quality datasets through centralized and government-approved data collection, publishes Periodic Reports on Acid Deposition in East Asia, leads joint research projects, offers capacity-building activities to enhance its Participating Countries’ technical capabilities, raises public awareness and strengthens cooperation with regional and global initiatives.

The EANET coordinates with other global and regional networks and initiatives to promote cooperation. In May-June 2024, the EANET, together with UNEP and ESCAP, are organizing the Workshop “Unlocking and Future-Proofing Air Quality Management in Asia”. The Workshop will provide a venue for EANET National Focal Points to discuss the future direction of its network and inputs for the development of its next Medium Term Plan for 2026-2030.
