AUSTIN -- If CapMetro transitioned its entire fleet of 512 transit buses to all-electric vehicles, it could significantly cut greenhouse gas emissions each year and reduce toxic air pollution that creates a public health hazard. A new report from TexPIRG Education Fund and Frontier Group, “Electric Buses: Clean Transportation for Healthier Neighborhoods and Cleaner Air,” shows that a full transition to electric buses in Austin could avoid an average of 22,644 tons of climate-altering pollution each year -- the equivalent of taking 4,371 cars off the road.
“There’s no reason we should be running dirty, polluting buses in our communities when we have better, cleaner options,” said Scoggin, state director of TexPIRG Education Fund. “Our research shows that whether commuters are on the bus or boarding the bus, they’re exposed to toxic air in high concentrations, while simultaneously, diesel contributes to global warming.”
More than 60 percent of the transit buses run on diesel, while just 0.2 percent of buses are all-electric. Numerous studies have shown that inhaling diesel exhaust can cause respiratory diseases and worsen existing conditions such as asthma. Diesel exhaust from buses poses a particular public health risk; buses primarily travel where there are lots of people, including in the more densely-crowded areas of cities, on the busiest roads, and near schools.
The good news is that all-electric buses are available and ready to roll, and they’re cleaner, healthier and often cheaper for transit agencies to run in the long-term. And with zero tailpipe emissions, electric school buses can significantly reduce people’s exposure to toxic fumes.
"Diesel can cause a number of health problems, including asthma and cancer, and unfortunately that's what is powering most of America's buses," said Alana Miller, policy analyst at Frontier Group and coauthor of the report. "Our report shows that all-electric buses can help cities address public health and climate concerns while saving money in the long-run."
The report identifies several ways Texas can pay for the transition to electric buses, including using Volkswagen settlement funds, state and federal grants, and utility investments. Texas is receiving $209 million as part of the Volkswagen “Dieselgate” settlement. A portion of that money could be used to purchase all-electric buses and charging infrastructure.
