The sustainable transport definition can be best described as any type of transport that does not rely on the world’s natural resources to power it. The aim of this type of transport is to reduce the negative impacts on the environment. It includes both public transport (electric buses, zero emissions buses, metro, train, trams, etc.) and private transport (pedestrians, bikes, scooters, electric vehicles, etc.).
The increase in greenhouse gases created by transport is increasingly a cause for concern in cities where atmospheric pollution indicators are starting to be considered a public health issue. Sustainable transport contributes to a reduction in damaging carbon dioxide (CO2) emissions, and therefore, to a reduction in atmospheric pollution and improved air quality in cities.
