Urban transportation is a significant contributor to carbon emissions, impacting air quality and public health. With millions of vehicles on the road, cities are challenged to balance mobility and sustainability. Transitioning to public transport systems powered by clean energy can significantly reduce emissions. Electric buses and trains, along with bike-sharing programs, offer viable alternatives to traditional vehicles. Additionally, promoting pedestrian-friendly infrastructure encourages walking, further decreasing reliance on fossil fuels. Implementing policies that support carpooling and the use of electric vehicles can also enhance urban sustainability. Addressing carbon emissions in transportation is essential for combating climate change and creating healthier cities.
