Atmospheric Environment Technology and Evaluation Technical Committee
1.Aim of activity
Although air quality standards for PM2.5 (particles with a diameter of 2.5 μm or less) are being achieved due to lower vehicle emissions, air quality standards for ozone continue to be unmet. Secondary particles in PM2.5 (gas components turned into particles through photochemical reactions) and ozone are complexly involved in photochemical reactions, and reducing the causative substances (precursors) has a linear improvement effect. This is different from conventional examples in which SPM in the atmosphere was reduced by reducing diesel PM in that it does not result in a reduction in SPM. In particular, we must evaluate the impact that the use of next-generation fuels that will achieve carbon neutrality will have on secondary particles and ozone. In order to improve the atmospheric environment, it is considered important to elucidate the individual components of automobile exhaust, elucidate the reaction mechanisms in the atmosphere, and assess the effects on health. Therefore, this committee will cover a wide range of research related to air pollutants, from understanding the current status of emissions, including measurement technology, and considering reduction methods, to atmospheric observation, and health effects. Composed of automotive engineers and researchers, atmospheric observation researchers, health effects researchers, and related administrative officials, the committee members and members share information by exchanging information on the latest research trends and regulatory trends. proceed.

4. Volunteer activities
･Continue discussions on elucidating mechanisms and efforts to reduce ozone (particularly secondary reactions in which gas components are generated through photochemical reactions), which is an issue in the atmospheric environment, and gathering information from experts in various fields. to deepen understanding and share information.
・We will continue to discuss the effects of global warming prevention measures/changes in the primary energy balance on the atmospheric environment and motorized society, and collect information from experts in various fields to gain deeper understanding and share information. We aim to
・We will discuss the actual state of automobile exhaust gas emissions in the real world, gain knowledge of its characteristics, and discuss the optimal evaluation method.
・Collect information from various experts regarding particle number regulations, gain knowledge of their characteristics, and discuss optimal evaluation methods/calibration methods.
- Understand the environmental policies of each country, discuss the risk factors that automobiles pose to the atmospheric environment, and show how automobiles should be in harmony with the environment.
