Incorporating Cooking Emissions To Better Simulate the Impact of Zero-Emission Vehicle Adoption on Ozone Pollution in Los Angeles
Despite decades of emission control measures aimed at improving air quality, Los Angeles (LA) continues to experience severe ozone pollution during the summertime. We incorporate cooking volatile organic compound (VOC) emissions in a chemical transport model and evaluate it against observations in order to improve the model representation of the present-day ozone chemical regime in LA. Using this updated model, we investigate the impact of adopting zero-emission vehicles (ZEVs) on ozone pollution with increased confidence. We show that mitigating on-road gasoline emissions through ZEV adoption would benefit both air quality and climate by substantially reducing anthropogenic nitrogen oxides (NO<sub><i>x</i></sub>) and carbon dioxide (CO<sub>2</sub>) emissions in LA by 28 and 41% during the summertime, respectively. This would result in a moderate reduction of O<sub>3</sub> pollution, decreasing the average number of population-weighted O<sub>3</sub> exceedance days in August from 9 to 6 days, and would shift the majority of LA, except for the coastline, into a NO<sub><i>x</i></sub>-limited regime. Our results also show that adopting ZEVs for on-road diesel and off-road vehicles would further reduce the number of O<sub>3</sub> exceedance days in August to an average of 1 day.
