Abstract
- Ozone (O<subscript>3</subscript>) is a pollutant of concern in urban areas because of its effects on health, crops, ecosystems, and materials. Despite efforts to meet the Japanese air quality standard for O<subscript>3</subscript> in the Kanto region, the attainment percentage is close to zero. Considering that O<subscript>3</subscript> formation is sensitive to emissions of volatile organic compounds (VOC) and nitrogen oxides (NO<subscript>x</subscript>), this study evaluated a range of reductions in the emissions of both precursors using a regional air quality model (ADMER-PRO) and estimated their benefits measured as the economic change due to O<subscript>3</subscript> concentration differences between scenarios. The simulation period was set during the 2016 O<subscript>3</subscript> season. The results showed that O<subscript>3</subscript> concentrations could be reduced using two approaches: significant reduction in VOC levels combined with minor NO<subscript>x</subscript> level changes or significant NO<subscript>x</subscript> emission reduction. Significant reduction in NO<subscript>x</subscript> levels was the most effective strategy for a generalized decrease in the O<subscript>3</subscript> levels in the Kanto region, and the benefit analysis revealed that the most significant economic impacts could be achieved by adopting the latter approach.
