The Greater Cleveland Regional Transit Authority (GCRTA) is making strides towards sustainable public transit by replacing diesel buses with a fleet of Compressed Natural Gas (CNG) vehicles. With a $2.7 million grant from Ohio's Diesel Emission Reduction Grant program, GCRTA will swap out five diesel buses with environmentally-friendly CNG models, reducing emissions and promoting cleaner air in Cleveland. The CNG buses not only offer a lower cost of fuel compared to diesel but also exhibit a 15% reduction in tailpipe emissions. Additionally, they operate 10 decibels quieter, enhancing the overall rider experience in Cleveland neighborhoods. GCRTA's transition to CNG aligns with Cleveland's climate action plan, aiming to decarbonize transportation emissions by 2050. While CNG presents benefits over diesel, such as lower emissions, the city recognizes the need for diverse energy sources like electric power and renewable natural gas to achieve emission reduction goals. A recent $10.6 million grant will enable GCRTA to purchase 10 battery-electric buses, further contributing to the city's sustainable transportation initiatives. Looking ahead, GCRTA is exploring advancements in zero-emissions technology, considering options like electric battery and hydrogen buses. While current FTA regulations delay the replacement of newer diesel buses until 2033, the organization remains committed to evaluating innovative technologies for a greener and more sustainable public transit system in Cleveland.
