Nations re-affirm their engagement to improve air quality globally through a new resolution at UNEA-6

Posted on by Aurélia Lemoine

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.

Air Quality Management Collaborative Efforts and Awareness Initiatives in Lao PDR

The objective of the panel discussion on Strengthening Acid Deposition and Air Quality Management in Lao PDR was to offer a forum to share information on air quality management and haze pollution. Representatives from government agencies  NGOs, and other development institutions participated actively in the panel discussion and shared their thoughts on the air pollution issues in the country.

The alarming increase in the heat index in Lao PDR and in the region in April 2023, combined with wildfires and high air pollution, has led to a collective agreement to raise awareness about the detrimental effects of air pollution. The government of Laos is taking various measures to address air pollution and raise public awareness about its impacts, including conducting public awareness activities led by the Ministry of Public Health and the Ministry of Natural Resource and Environment and collaborating with relevant sectors to prevent air pollution from the agricultural sector. The National University of Laos (NUOL) has also introduced a supplementary curriculum on air pollution and air quality control.

The collaboration between the government and local communities was emphasized, involving engagement with local authorities and residents in educational programs. In the agricultural sector, the cassava farming practice is becoming a significant concern, leading to nutrient degradation in the soil and farmers resorting to clearing more land. Facing this issue, support is being provided to community-managed areas for sustainable crop preparation, discouraging the shifting of cultivation sites and promoting the use of plant residues to reduce burning.

Local government entities are also encouraged to collaborate with research institutes and other sectors to manage and prevent air pollution. The World Bank, in partnership with the NRERI, is developing an environmental and waste management project, aiming to enhance communication and access to educational resources through the development of online platforms including a mobile application, for public air quality monitoring.

The National Awareness Workshop participants highlighted the status of air quality monitoring stations, identified major sources of air pollution, and emphasized the importance of capacity building and international cooperation in addressing the transboundary haze issue. While efforts are made to improve the air quality assessment, these need to be further strengthened. Collaboration among various local and international stakeholders is key to addressing the air quality issue in Lao PDR.

The EANET Emission Inventory Webinar Workshop on Open Biomass Burning

Posted on by Aurélia Lemoine

8 December 2022 – Niigata, Japan

The Network Center (NC) for the EANET organized the EANET Emission Inventory Webinar Workshop on Open Biomass Burning on 5 December 2022 gathering expert panelists from Japan, Thailand, the USA, and about 50 participants from the EANET countries. Starting with lecture presentations on methodologies to estimate emissions from open biomass burning sources, evaluate uncertainties in estimated emissions, and analyze influences of emissions using air quality models, the Workshop also included, in the second session, presentations from participants on open biomass burning emissions in their respective countries, concluded by discussions on the EANET’s potential role and activities related to open biomass burning.

.

Expert Lectures and Use Cases on Open Biomass-Burning Emission Inventories from Asia and Beyond
Screenshot from some panelists and participants during the virtual Workshop

Dr. Savitri Garivait from the Joint Graduate School of Energy and Environment, Centre of Excellence on Energy Technology and Environment, King Mongkut’s University of Technology Thonburi, Thailand, presented a comprehensive lecture introducing basic knowledge and information related to open biomass burning emissions. First, Dr. Savitri introduced various types of open biomass burning, namely, forest fires, agricultural waste burning, and solid waste burning. Then, she presented methodologies to estimate emissions from open biomass burning such as basic equations, how to collect activity data as well as information necessary for spatial distribution and temporal variation, and selection of emission factors. To produce activity data, Dr. Savitri emphasized the importance of questionnaire surveys on local and specific data, in order to reduce uncertainties. She finally presented detailed case studies on the evaluation of the contribution of emissions from open biomass burning to the overall emissions and air pollution in Thailand and the Bangkok Metropolitan Region.

 

Dr. Kristofer Lasko, from the Geospatial Research Laboratory, at the Engineer Research and Development Center (ERDC), United States, provided a lecture focusing on uncertainties of open biomass burning emission inventories, especially on the amount of burned dry matter based on satellite observation data, emission factors for different biomass burning types, and land cover type maps to determine which emission factors to be applied. In his presentation, he explained the major causes of uncertainties based on satellite data including influences of cloud coverage at or near the time of burning, the insufficient spatial resolution to detect agricultural fires, and the limitation in determining actual burned amounts in the field via remote sensing data. For emission factors, Dr. Lasko emphasized the difficulty is not only the uncertainty of each factor but also the variations due to aspects such as variation in burning practices (e.g., piled residue burn vs. open field burn) and moisture. In his presentation, case studies for PM2.5 emission inventories of Viet Nam and the Southeast Asian region were also showcased.

Dr. Katsuhige Uranishi, Department of Life and Environment Engineering, Faculty of Environmental Engineering, the University of Kitakyushu, Japan, provided a lecture about how to evaluate the influences of emissions from open biomass burning on the air quality of neighboring areas using air quality models. First, Dr. Uranishi introduced the basic knowledge and settings of an air quality modeling system by using the Weather Research and Forecasting model and Community Multiscale Air Quality model (WRF/CMAQ) system as an example. He then also presented the Brute-force method, a typical methodology to estimate the contribution of PM2.5 sources using an air quality modeling system. Finally, Dr. Uranishi explained simulation examples for the evaluation of PM2.5 transboundary transport, through case studies in Japan. Because uncertainties are not only in open biomass burning emissions but also in the modeling systems, Dr. Uranishi emphasized that the model performance must be evaluated with observation data prior to estimating air pollution levels or impact. He also recommended reviewing past studies to find appropriate settings of air quality modeling systems to target specific problems.

.

Open Biomass-Burning Emissions Status and Control Measures in East Asia

Participants, in the second session, shared various information about open biomass burning emissions in their respective countries. The presentations covered major sources of open biomass burning emissions and how the emissions are estimated or evaluated in each participant’s country. They also considered how open burning influences air quality and what current control measures are in place in each represented country. These presentations and practical activities were followed by discussions on the EANET’s Project Activities related to open biomass burning emissions including national emission inventories to be organized in 2023.

Participants expressed interest to attend future capacity-building activities related to emission inventories not only from open biomass burning but also from other sources. The monitoring of emission sources to determine local emission factors was also suggested. The NC for the EANET, the organizer of the Workshop will consider the possible future activities to the EANET Project Fund.

1 February 2023 – Niigata, Japan

The Network Center for the EANET co-organized the 13th International Workshop on Atmospheric Modeling Research in East Asia with the community of MICS-Asia, on 22-23 December 2022. About 60 participants joined the virtual workshop.

.

Improving Air Quality Models: from Data to Policy

According to the United States Environment Protection Agency (EPA), air quality modeling is “a mathematical simulation of how air pollutants disperse and react in the atmosphere to affect ambient air quality.” Through these calculations, researchers and policymakers develop predicted scenarios and design strategies to reduce the adverse effects of air pollution.

Over the years, the EANET has maintained a close relationship with the community of Model Inter-Comparison Studies for Asia (MICS-Asia). The International Workshop on Atmospheric Modeling Research in East Asia is a regular workshop of MICS-Asia which has received support from the EANET throughout the previous Medium Term Plans and was part of the EANET Project Activities in 2022. Summaries of previous MICS-Asia workshops are available in the Reports of the Session of the Scientific Advisory Committee (SAC) on the EANET.

Four working groups were established as part of the MICS-Asia Phase IV: the Air Quality Model working group, the Air Quality and Climate Model working group, the Emission Inventory working group, and the Observation working group. MICS-Asia Phase IV working groups focus on specific issues including the intercomparison of air quality models, the study of the influence of climate change on the status of air quality, the development of reliable emission inventories for model working groups, and the survey and collection of data to establish trends of concentrations of air pollutants in East Asia.

Among other sources, MICS-Asia experts referred to the results of the EANET’s 4th Periodic Report on the State of Acid Deposition in East Asia (PRSAD4) and to the EANET monitoring data to conduct their research.

Intensive training for city government officials: EANET-Clean Air Asia Workshop on Emission Inventory Development for the Management of Emissions from the Transport Sector

Posted on by Aurélia Lemoine

24 November 2022 – Manila, Philippines

The Network Center for the EANET (NC) and Clean Air Asia organized the EANET-Clean Air Asia Workshop on Emission Inventory Development for the Management of Emissions from the Transport Sector, an intensive training for city government officials held on November 23, 2022, in Manila, Philippines, as a side-event to the 24th Intergovernmental Meeting (IG24) on the EANET. It was attended by more than 90 participants, in-person and online, representing 14 countries from the EANET Region and beyond, gathered to learn about the different tools to calculate emissions from the transport sector and discuss the importance of using data for policy.

.

Developing an Emission Inventory

Developing an emission inventory is critically important for air pollution management purposes. The accurate estimation of emissions from various sources such as factories, power plants, cars, households, etc… allows the production of basic data, using scientific tools like environmental assessments, for policy-makers to prevent the adverse effects on human health and ecosystems of air pollution.

Presentations and panel discussion with Ms. Everlyn Tamayo, Dr. Didin Agustian Permadi, Dr. Shaojun Zhang, Ms. Kathleen Dematera-Contreras, Dr. Raymund Abad and Mr. Myron Alcanzare introduced the general principle of the emission inventory, outputs, and typical actions to be applied to policy development.

Participants also worked on an exercise on motor vehicle emissions by using a desktop program/application developed by Dr. Permadi with support from Clean Air Asia, allowing participants to apply the methodology to their respective countries/cities.

.

Engaging Policymakers

Through the workshop, participants learned about the variety of methods and tools to calculate emissions from the transport sector, while noting that the final approach to be implemented would vary depending on the objectives and available resources of the personnel or city. Calculating emissions under different scenarios was recommended as it provides an overview of the impact of measures or policies. Finally, the importance of high-quality data was emphasized to build capacity and strengthen the engagement between policymakers and researchers performing the emissions inventory.

 .

Ways Forward

The development of an emission inventory is a powerful and essential tool for understanding the status of air pollutants emissions and considering the effectiveness of mitigation measures. EANET activities related to the development of emission inventories will continuously be conducted in the future. In 2023, EANET will organize a webinar workshop for capacity building on emission inventories related to combustion sources and explore all possibilities to strengthen cooperation with other organizations, including Clean Air Asia.
