How does public transport help in reducing carbon footprint?

Public transport helps in reducing carbon footprint primarily because it typically reduces the number of vehicles on the road. When more people use buses, trains, or trams, fewer private cars are in use, which leads to a significant decrease in the total emissions generated from vehicles. This is important because individual cars often produce more greenhouse gases per passenger compared to public transport options that can carry many people at once.

By decreasing the number of cars, public transport helps to lower traffic congestion as well, which in turn reduces idle time and fuel consumption. It promotes a more efficient use of energy resources by maximizing passenger capacity. In addition to this, when public transport systems are utilized, they can help to create more sustainable urban environments by encouraging less dependence on personal vehicles, ultimately contributing to lower overall carbon emissions in cities.
