Define "sustainable transport".

Sustainable transport refers to transportation methods that promote lower emissions and have a reduced environmental impact. This concept emphasizes the need to meet the current mobility needs of people and goods in a way that does not compromise the ability of future generations to meet their own needs. Sustainable transport encourages the use of renewable energy sources, efficient public transit systems, non-motorized transport options like cycling and walking, and innovative technologies that lower the carbon footprint associated with transportation.

This definition aligns with the principles of sustainability, as it seeks to minimize ecological damage while supporting social and economic needs. Sustainable transport can contribute to reduced air pollution, decreased reliance on fossil fuels, and the enhancement of quality of life in urban and rural areas. It encompasses a wide range of solutions, including electric vehicles, car-sharing programs, and comprehensive public transport networks that provide equitable access to mobility.

The other options do not capture the essence of sustainable transport; for instance, options focusing solely on cost efficiency or private vehicle use neglect the broader environmental and social benefits that sustainable transport aims to achieve. Similarly, options promoting higher emissions contradict the fundamental goal of sustainability, which is to lower negative impacts on the planet.
