The transport sector is a big contributor to greenhouse gas emissions, which are causing climate change. More people owning cars, especially in developing countries, is making the problem worse. Urban planning can help by designing cities to reduce the need for driving, like having homes and jobs close together. This can lead to shorter trips and less use of cars. In the long run, urban planning can be effective in reducing emissions by encouraging people to use public transport, walk, or cycle instead of driving. So, designing cities smartly can play a big role in fighting climate change caused by transportation.
