based on multiple factors: Environmental impacts, cost to implement, customer desire, ability to provide the fuel in each location.” Lane said the company doesn’t track specific health
metrics of bus drivers or communities due to privacy concern, but uses the latest research to promote sustain- able fuels as a way to improve community health. The company tracks its fleet’s GHG and particulate
emissions based on fleet size, fuel type and age. “We measure real number and an average/mile,” Lane said. “Our particulate have decreased in real numbers for the fleet despite our annual mileage increasing as we replace older diesels with newer, cleaner diesels and other alternative fueled vehicles.” Los Angeles Unified School District (LAUSD) transports 31,000 of its 408,000 students across 710 square miles with a fleet of 1,300 buses powered by a mix of electric, propane, gas, diesel, and compressed natural gas (CNG). “The district started incorporating clean diesel in 2002, CNG in 2004, propane in 2009, and electric in
2019,” noted spokesperson Britt A. Vaughan. “These steps were part of our broader sustainability strate- gy aimed at cutting emissions, lowering operational costs, and setting a strong example in the shift to eco-friendly transportation.” Research shows a reduction of 75 to 95 percent
NOx emissions when comparing CNG to diesel buses, Vaughan noted. “The transition to cleaner fuels has had a positive
environmental impact, including improved air quality and reduced greenhouse gas emissions,” he added. “This aligns with the district’s sustainability goals and con- tributes to a healthier environment for our students and community.” Community members appreciate the district’s efforts
to prioritize environmental health and sustainability, said Vaughan, adding the cleaner air has resulted in few- er reports of respiratory issues in students and drivers and overall better air quality in and around the buses. ●
