PHILADELPHIA, Pennsylvania, Feb. 4 (TNSRep) -- PennEnvironment issued the following news release: To protect our children's health and environment, PennPIRG Education Fund and PennEnvironment Research & Policy Center have released a new report to identify new, cutting-edge ways that utility companies can assist school districts in paying for zero-emission buses, and how schools can reap the long-term benefits. The vast majority of school buses in the United States run on diesel, a climate-polluting fossil fuel that releases toxic fumes linked to life-threatening health problems such as asthma, bronchitis and cancer. Emitting over 5.3 million tons of greenhouse gases per year, not only are diesel buses bad for our children's health, they're also bad for the climate. However, there is a cleaner, safer and more long-term budget-friendly alternative: zero-emission electric school buses.
