Gaziantep Metropolitan Municipality in Turkey is taking significant steps towards sustainable transportation by introducing 20 electric buses to its urban public transportation fleet. This initiative aims to enhance the city's air quality and reduce carbon emissions. Additionally, the municipality is focused on increasing the use of renewable energy sources, with plans to purchase the 'Sustainable and Smart Mobility Strategy Plan for Gaziantep' under the cooperation of the Ministry of Transport and Infrastructure and the European Union. Furthermore, Gaziantep Metropolitan Municipality is actively exploring the possibility of incorporating hydrogen-powered buses into its transportation system. Mayor Fatma Şahin and her team are working on implementing these buses after studying similar systems in Cologne, Germany. The municipality sees hydrogen as a key element in the fight against climate change, highlighting the importance of utilizing this technology to combat environmental challenges. By introducing hydrogen buses that run on water vapor, Gaziantep aims to lead the way in sustainable transportation and reduce greenhouse gas emissions. Currently, a significant portion of the municipal buses in the city operate on CNG, and there are plans to expand this environmentally friendly approach. Overall, the efforts of Gaziantep Metropolitan Municipality towards green transportation, including the adoption of electric buses and the potential incorporation of hydrogen-powered buses, reflect a positive step towards creating a more environmentally sustainable urban environment.
