19 October 2021 – Bangkok, Thailand

The Asia Center for Air Pollution Research (ACAP), the Network Center (NC) for the EANET, organized the EANET Emission Inventory Workshop on 18 October 2021, gathering over 50 participants from 9 countries, to develop regional air quality management skills.

Why are emission inventories important?

To tackle atmospheric environment problems, it is essential to understand the status of air pollutants’ emissions and consider mitigation measures’ effectiveness. The emission inventory is an essential tool to obtain such information and to build appropriate atmospheric environmental policies.

Building Capacity at a Regional Level

The objectives of the EANET Emission Inventory Workshop were to understand the role of an emission inventory in air quality management, obtain general information on an emission inventory, and learn basic knowledge on the development and application of an emission inventory.

For this purpose, invited experts provided five lecture presentations on developing and applying an emission inventory. Furthermore, the participants, selected by the National Focal Points (NFPs) of each EANET Participating Country, delivered short presentations about issues related to national emission inventories in their countries.

Through discussions among lecturers and participants, the event aimed to enhance participants’ knowledge and encourage the development of national emission inventories.

Ways Forward

In conclusion, participants emphasized the usefulness of such capacity-building activities and noted that it could be interesting, in the future, to focus the workshop’s content on regional specificities.

Participants also highlighted that both technical (such as providing guidelines) and financial aspects are necessary for conducting emission inventory activities. Taking these observations into account, it may be interesting to focus EANET’s future activities on this demand.

Furthermore, the participants pointed out the benefits of sharing emission inventories throughout the EANET region to better understand the atmospheric environment issues and compare methodologies, including emission factors.
