The Metropolitan Transit Authority of Harris County, known as Houston Metro, has recently launched its first zero-emission electric buses on two bus routes in Houston, Texas. The 402 Bellaire Quickline route and the 28 OST-Wayside route have seen the implementation of these new electric buses, replacing older diesel buses. The move is part of an effort to improve community accessibility and address environmental justice issues. Houston Metro's Board Chair, Elizabeth Gonzalez Brock, emphasized that the transition to electric buses is an investment in customers, particularly those in minority, low-income, and transit-dependent neighborhoods. The 402 Bellaire Quickline route connects Chinatown to the Medical Center, serving areas like southwest Houston and the city of Bellaire, while the 28 OST-Wayside route benefits neighborhoods like Fifth Ward, historically affected by air pollution. This shift towards zero-emission vehicles is in line with the authority's broader sustainability goals. Although Houston Metro already operates over 400 clean-running diesel-electric hybrid buses, a Federal Transit Administration grant will soon bring a total of 20 electric buses and 14 hydrogen fuel cell electric buses to further enhance the city's transit system.
