In Spring 2022, civil and environmental engineering students from UC Berkeley worked with community organizations within the Stockton AB 617 area to identify local air pollution sources and design mitigation strategies. This 4-part blog series highlights the student projects and resources to share with the community. 

Part 2 focuses on shipping, transportation, and cooking related emissions in the Stockton AB 617 area. Check out these StoryMaps: 


  • Shipping Activity Emissions: for the Port of Stockton, students used ship traffic data to estimate that the Port’s emissions increased by 30% from 2018 to 2021

  • Trucking Emissions: analyzing truck routes in Stockton, students found that 63% of people within the AB 617 boundary live within 0.1 mi from a truck route, leading to high exposure from diesel truck emissions, compared to only 38% for Stockton overall; this team also created resources for truckers. 

  • Commercial Cooking: commercial cooking contributes to an estimated 25% of the total emission of PM2.5 in Stockton; this team created accessible resources for restaurants to follow to apply to the Restaurant Charbroiler Technology Partnership (RCTP) to reduce their emissions.

  • Electric Vehicle (EV) Workforce Development: this team explored strategies to train EV mechanics to support growth of EV infrastructure in Stockton, so that Stockton can take the lead in the transition to EVs.
