The Federal Transit Administration recently allocated substantial grants totaling over $1.5 billion to support the transition to low- or no-emission buses in 117 communities across the United States. Around 80% of the supported bus purchases are set to incorporate zero-emission or low-emission technologies, signifying a notable step towards environmentally friendly public transportation solutions. Various states, including California, Washington, and New Jersey, have seized the opportunity to invest in battery electric, fuel cell, and hybrid buses to modernize their fleets and diminish harmful emissions. The funding not only focuses on advancing clean energy technologies but also on enhancing air quality, alleviating traffic congestion, and fortifying mass transportation systems in multiple neighborhoods and communities. The grants aim to facilitate the purchase of clean buses, fueling infrastructure, and charging facilities, enabling transit agencies to pursue ambitious environmental goals and contribute to the overall improvement of public transportation services.
