Urban planning plays a crucial role in mitigating carbon emissions. By promoting denser, mixed-use development, cities can reduce the need for long commutes, thereby decreasing transportation-related emissions. Additionally, incorporating green spaces and sustainable infrastructure, such as bike lanes and public transportation systems, can encourage eco-friendly modes of travel. Furthermore, efficient energy use in buildings and the integration of renewable energy sources like solar and wind power can significantly lower urban carbon footprints. Well-planned cities not only enhance quality of life but also contribute to a more sustainable future.
