Emission zone shouldnt be the issue, it is about the amount of cars and road safety for every user. Check e.g. the Dutch road design, where many kids ride bikes. This is already for decades, and has nothing to do with emission zones. But another road design can also help reducing emissions. It is about how many people can travel safe, and with big cities, you have to reduce cars to increase the amount of people that can travel safe, like bikes, walking, and public transport. Road and city design is very important for a livable city.
