The city of Phoenix has taken a significant step towards sustainability by introducing 19 new hybrid-electric buses to its public transit system. These buses, running on biodiesel with an electric motor, promise higher fuel economy, lower pollution levels, and quieter operations. The move is part of Phoenix's ambitious goal to have a zero-emissions bus fleet by 2040. In addition to phasing out 500 traditional gas and diesel buses, the city plans to incorporate all electric and hydrogen fuel cell buses into its fleet from the next year. Brenda Yanez, a spokesperson for Phoenix’s Public Transit Department, highlighted the city's commitment to creating a more sustainable environment with fewer emissions and a better future for its residents. The initiative has received support from the Phoenix City Council, which unanimously approved the transition plan in 2022. Funding for the new buses primarily comes from a federal grant secured under the 2021 bipartisan infrastructure law. The move towards greener transportation not only benefits the environment but also aligns with the city's vision for a more sustainable and efficient public transit system.
