Webinar Workshop for Emission Inventory of VOCs and its Application for Policy Consideration – Join us on December 4th!

Posted on by Aurélia Lemoine

.

1. Background

Volatile Organic Compounds (VOCs) are a group of organic chemicals that have a high vapor pressure and comprise various components with different chemical characteristics. In addition to the toxic effects of some VOCs, considering atmospheric environmental problems in EANET Participating Countries, VOCs play important roles as precursors of ozone and secondary PM2.5.

To tackle severe air pollution problems, it is essential to understand the status of VOCs’ emissions and consider effective mitigation measures. Emission inventories are essential to obtain such information and help to make appropriate atmospheric environmental policies. However, VOCs’ emissions are from varieties of sources especially evaporative sources such as solvent use, extraction processes of fossil fuels, and evaporative emissions from gasoline vehicles, and thus, a lot of data and information is necessary to estimate emissions of VOCs. Furthermore, in addition to anthropogenic emissions, biogenic sources are important for VOCs’ emissions. Therefore, the framework for the national emission inventory of VOCs is different from other sources.

The Webinar Workshop for Emission Inventory of VOCs and its Application for Policy Consideration will take place on Wednesday 4 December 2024, from 12:30 to 16:35 (UTC+7), via Zoom. The event is organized by the Asian Center for Air Pollution Research (ACAP), serving as the Network Center for the EANET and with the support of the EANET Project Fund.

 .

2. Objectives

The objectives of the Emission Inventory Webinar Workshop are to learn basic methodologies to estimate emissions of VOCs from stationary sources and road transport, especially for evaporative sources as well as from biogenic sources. In addition, the roles of emission inventory in atmospheric environmental management, air quality modeling of VOCs, and control measures of VOCs are introduced as applications of emission inventories for policy consideration.

Online Workshop on the Utilization of Low Cost Sensors (LCS) for Air Quality Monitoring: Recommendations and Strategies – Join us on November 6th!

Posted on by Aurélia Lemoine

.

1. Background

Air quality administrations usually use conventional reference monitors. However, low- and middle-income countries cannot fully use these in their air quality monitoring networks due to the limitation of resources. Less expensive and smaller monitoring devices, so-called Low-Cost Sensors (LCS), are capable of filling the gaps in existing air quality monitoring networks, and the data measured by LCS may provide information for policy-relevant air quality measures.

In most areas in the Asian region, air quality monitoring capacities of the national and local governments are still limited and need to be developed to improve their air quality to achieve Sustainable Development Goals (SDGs). Considering emerging sub-regional-scale and serious seasonal air pollution events, such as Ozone and PM2.5 pollution, building a network of reliable and internationally comparable air quality data becomes more important. Thus, practitioners must consider how they can wisely select and use reliable LCS with a network of reference-level monitors in an integrated manner for enhanced air quality monitoring.

The EANET has been supporting the development of air quality monitoring networks in the East Asia region in partnership with its 13 Participating Countries’ governments and scientists, assisting them to develop local capacity of scientific and internationally comparable air quality monitoring. The EANET has expanded its scope to wider air pollution issues in 2021, and the wise use of reliable LCS is one of the EANET’s interests aiming at developing its monitoring capacities. The EANET project titled “Methodology Study for Development of LCS Hybrid Air Quality Monitoring Network (HAQMN)” has been implemented since 2022, with the support of the Ministry of the Environment, Japan, and the EANET Project Fund.

Besides the above-mentioned EANET project, there are other projects implementing air quality monitoring using LCS networks of urban and regional scales in East Asia. These networks are collecting the data via the Internet and some projects demonstrate real-time data. These preceded projects show how LCS technology and citizen participation can contribute to monitoring and improving air quality. They also show how data transparency and open access are important to increase public awareness of air pollution issues.

The Online Workshop on the Utilization of Low-Cost Sensors for Air Quality Monitoring: Recommendations and Strategies will take place on Wednesday 6 November 2024, from 13:00 to 16:45 (UTC+7), via Zoom. The event is organized by the Asian Center for Air Pollution Research (ACAP), serving as the Network Center for the EANET.

 .

2. Objectives
  • To share information on technical requirements, data management, and visualization, citizen participation, policy involvement, and business models by preceded projects on LCS monitoring networks in the Asian region
  • To discuss scopes and challenges for establishing a sustainable LCS monitoring network in East Asia and for sharing LCS data and scientific findings to strengthen efforts to improve the regional air quality in East Asia.
  • To consider recommendations on future directions of LCS monitoring in EANET

.

3. Expected Participants

Policymakers, practitioners, and technical officers of local/national governments related to air pollution issues in the Participating Countries of EANET and other countries in Asia.

In addition to the Core Budget of the EANET to support its activities focused on monitoring, and supporting its meetings, the IG25 approved eleven EANET Projects in 2024 primarily focusing on capacity building for government officials but also concerning key air quality management-related issues such as on Volatile Organic Compounds (VOCs), low-cost sensors (LCS), emissions inventories, and source apportionment projects in the region.

The EANET Projects for 2024 received funding through the EANET Project Fund, EANET’s financial mechanism allowing collaboration with implementation partners and co-financing from outside the EANET Network.

The total funding for Project Activities in 2024 is $605,000, including funding from the EANET Secretariat and NC funds, additional financial support from Japan (MOEJ), and from the Republic of Korea (NIER).

EANET’s Initiatives for a Comprehensive Understanding of VOCs

Volatile Organic Compounds (VOCs) are components of air pollution that include a complex mixture of hundreds of carbon-containing gases. VOCs also include a wide variety of chemicals, some of which can cause short- and long-term adverse health effects. However, due to the unique characteristics of VOCs and the relatively high cost of measurement, VOCs monitoring and its related activities in the EANET region are still at an early stage. Since February 2023, the EANET has launched the “Feasibility for Promoting VOCs related Capacity Building in the EANET” project as part of the first batch of EANET Projects funded by the EANET Project Fund.

The EANET Workshop on Knowledge Sharing for VOCs Related Activities aimed at providing a complete understanding of VOCs related activities from the monitoring design to policy implementation, and to foster a comprehensive understanding and collaboration in the field of VOCs by bringing together experts, researchers, and practitioners in a multidisciplinary platform.

Mr. Yu Kamei, Director of the International Cooperation Office, Environment Management Bureau, Ministry of the Environment, Japan (MOEJ) and Engr. Marcelino N. Rivera Jr. OIC of the Environmental Quality Management Division of the Environmental Management Bureau (EMB) of the Philippines,  Central Office, on behalf of the EMB Director and concurrent Assistant Secretary Gilbert C. Gonzales, delivered opening remarks. Five presentations followed and covered VOC-related activities, from monitoring to emission control. Mr. Bert Fabian, Coordinator, Secretariat for the EANET moderated the Workshop.
