Sustainable transport or green transport - Forum

Sustainable transport (or green transport) is a concept, an ideology and, in some countries, a governmental policy that consists of strengthening or replacing the current transport systems of an urban/suburban area with more fuel-efficient, space-saving and healthy lifestyle-promoting alternatives. The term refers to any means of transport with low impact on the environment, and includes human or animal muscle-powered vehicles, low-carbon fueled vehicles, any kind of vehicle using a renewable source of energy for its propulsion. The most common usage of green transport is walking.



A common form of green transport vehicles are hybrid vehicles. Hybrid vehicles use an internal combustion engine combined with an electric engine. Biofuel powered vehicles use fuels derived from plant sources, such as vegetable oil, biodiesel, or bioalcohol for their propultion.



Sustainable transport systems make a positive contribution to the environmental, social and economic sustainability of the communities they serve. Transport systems exist to provide social and economic connections, and people quickly take up the opportunities offered by increased mobility. The advantages of increased mobility need to be weighed against the environmental, social and economic costs that transport systems pose.



Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions.[2] Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog.



The social costs of transport include road crashes, air pollution, physical inactivity, time taken away from the family while commuting and vulnerability to fuel price increases. Many of these negative impacts fall disproportionately on those social groups who are also least likely to own and drive cars. Traffic congestion imposes economic costs by wasting people's time and by slowing the delivery of goods and services.



Traditional transport planning aims to improve mobility, especially for vehicles, and may fail to adequately consider wider impacts. But the real purpose of transport is access - to work, education, goods and services, friends and family - and there are proven techniques to improve access while simultaneously reducing environmental and social impacts, and managing traffic congestion. Communities which are successfully improving the sustainability of their transport networks are doing so as part of a wider programme of creating more vibrant, livable, sustainable cities.

The term sustainable transport came into use as a logical follow-on from sustainable development, and is used to describe modes of transport, and systems of transport planning, which are consistent with wider concerns of sustainability. There are many definitions of the sustainable transport, and of the related terms sustainable transportation and sustainable mobility.



One such definition, from the European Union Council of Ministers of Transport, defines a sustainable transportation system as one that:

* Allows the basic access and development needs of individuals, companies and society to be met safely and in a manner consistent with human and ecosystem health, and promotes equity within and between successive generations.

* Is Affordable, operates fairly and efficiently, offers a choice of transport mode, and supports a competitive economy, as well as balanced regional development.

* Limits emissions and waste within the planet’s ability to absorb them, uses renewable resources at or below their rates of generation, and uses non-renewable resources at or below the rates of development of renewable substitutes, while minimizing the impact on the use of land and the generation of noise.
