What does "sustainable transport" aim to achieve?

Sustainable transport aims to achieve transportation methods that have minimal environmental impact, which is the essence of option B. This concept emphasizes reducing the negative effects of transportation on the environment while promoting efficient and equitable mobility solutions. Goals include minimizing greenhouse gas emissions, reducing air and noise pollution, conserving energy and resources, promoting social equity, and fostering economic development in a way that supports ecological balance.

The focus on minimal environmental impact includes the use of renewable energy sources, enhancements in public transport systems, the promotion of non-motorized transport like cycling and walking, and the integration of sustainable practices into transportation planning and design. This holistic approach ensures that transportation meets the needs of individuals and society without compromising the health of the planet or future generations.

Other options do not reflect the true objective of sustainable transport. For instance, high environmental impact would directly contradict sustainability goals, while focusing solely on road infrastructure ignores the broader range of transportation modalities necessary for sustainability. Additionally, enforcing stricter regulations might be a part of the solution but does not encapsulate the overall aim of achieving minimal environmental impact through better practices and innovations in transportation.
