Sustainable transport refers to the broad subject of transport that is or approaches being sustainable. Within CASwiki cycling and Road safety have their own separate articles. This article collates information covering the topics: Sustainable travel, reduced dependence on cars, reduced dependence on flying, walking, water transport and school travel.

Sustainable transport systems make a positive contribution to the environmental, social and economic sustainability of the communities they serve.

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. W

Sustainable transport is fundamentally a grassroots movement, albeit one which is now recognised as of citywide, national and international significance.

Whereas it started as a movement driven by environmental concerns, over these last years there has been increased emphasis on social equity and fairness issues, and in particular the need to ensure proper access and services for lower income groups and people with mobility limitations, including the fast-growing population of older citizens. Many of the people exposed to the most vehicle noise, pollution and safety risk have been those who do not own, or cannot drive cars, and those for whom the cost of car ownership causes a severe financial burden.

Events[edit | edit source]

Carfree city[edit | edit source]

A carfree city or car free city is a population center that relies primarily on public transport, walking, or cycling for transport within the urban area. Carfree cities greatly reduce petroleum dependency, air pollution, greenhouse gas emissions, automobile crashes, noise pollution, and traffic congestion. Some cities have one or more districts where motorized vehicles are prohibited, referred to as car-free zones. Many older cities in Europe, Asia, and Africa were founded centuries before the advent of the automobile, and some continue to have carfree areas in the oldest parts of the city -- especially in areas where it is impossible for cars to fit, e.g. in narrow alleys. W

Car-free movement[edit | edit source]

The Hague car-free city-centre 24.JPG

The car-free movement is a broad, informal, emergent network of individuals and organizations including social activists, urban planners and others brought together by a shared belief that large and/or high-speed motorized vehicles (cars, trucks, tractor units, motorcycles, ...) are too dominant in most modern cities. The goal of the movement is to create places where motorized vehicle use is greatly reduced or eliminated, to convert road and parking space to other public uses and to rebuild compact urban environments where most destinations are within easy reach by walking, cycling or public transport. W

Carpooling[edit | edit source]

Carpooling only lane

Carpooling (also car-sharing, ride-sharing, lift-sharing and covoiturage), is the sharing of car journeys so that more than one person travels in a car.

By having more people using one vehicle, carpooling reduces each person's travel costs such as fuel costs, tolls, and the stress of driving. Carpooling is seen as a more environmentally friendly and sustainable way to travel as sharing journeys reduces carbon emissions, traffic congestion on the roads, and the need for parking spaces. Authorities often encourage carpooling, especially during high pollution periods and high fuel prices. W

Carsharing[edit | edit source]

Carsharing or car sharing (US) or car clubs (UK) is a model of car rental where people rent cars for short periods of time, often by the hour. They are attractive to customers who make only occasional use of a vehicle, as well as others who would like occasional access to a vehicle of a different type than they use day-to-day. The organization renting the cars may be a commercial business or the users may be organized as a company, public agency, cooperative, or ad hoc grouping.

Carsharing contributes to sustainable transport because it is a less car intensive means of urban transport, and according to The Economist, carsharing can reduce car ownership at an estimated rate of one rental car replacing 15 owned vehicles. W

Flexible carpooling[edit | edit source]

Flexible carpooling is carpooling that is not arranged ahead of time, but instead makes use of designated meeting places. It seeks to replicate the informal 'slug-lines' that form in Washington DC, Houston, and San Francisco, by establishing more formal locations for travelers to form carpools without advance contact. W

Peer-to-peer carsharing[edit | edit source]

Peer-to-peer carsharing (also known as person-to-person carsharing and peer-to-peer car rental) is the process whereby existing car owners make their vehicles available for others to rent for short periods of time.

Peer-to-peer carsharing is a form of person-to-person lending or collaborative consumption, as part of the sharing economy.

As with person-to-person lending, enabling technology for this behavior has been the Internet and the adoption of geo-location-based service. W

Share taxi[edit | edit source]

A share taxi is a mode of transport which falls between both taxicabs and buses. These vehicles for hire are typically smaller than buses and usually take passengers on a fixed or semi-fixed route without timetables, but instead departing when all seats are filled. They may stop anywhere to pick up or drop off passengers. Often found in developing countries, the vehicles used as share taxis range from four-seat cars to minibuses. They are often owner-operated. W

Shared transport[edit | edit source]

Shared transport is a term for describing a demand-driven vehicle-sharing arrangement, in which travelers share a vehicle either simultaneously (e.g. ride-sharing) or over time (e.g. carsharing or bike sharing), and in the process share the cost of the journey, thereby creating a hybrid between private vehicle use and mass or public transport.

Shared transport systems include carsharing (also called car clubs in the UK), bicycle sharing (also known as PBS or Public Bicycle Systems), carpools and vanpools (aka ride-sharing or lift-sharing), real-time ridesharing, slugging, casual carpooling, community buses and vans, demand responsive transit (DRT), paratransit, a range of taxi projects and even hitchhiking and its numerous variants.

Shared transport is taking on increasing importance as a key strategy for reducing greenhouse gas and other emissions from the transport sector in the face of the global climate emergency by finding ways of getting more intensive use of vehicles on the road. W

Slugging[edit | edit source]

Slug Line.gif

Slugging, also known as casual carpooling, is the practice of forming ad hoc, informal carpools for purposes of commuting, essentially a variation of ride-share commuting and hitchhiking. Typically slugging is motivated by an incentive such as a faster HOV lane or a toll reduction. While the practice is most common and most publicized in the congested Washington, D.C. metropolitan area, slugging also occurs in San Francisco, Houston, and other cities. W

Active mobility[edit | edit source]

Wikipedia W icon.svg

Active mobility, soft mobility, active travel, active transport or active transportation is the transport of people or goods, through non-motorized means, based around human physical activity. The best-known forms of active mobility are walking and cycling, though other modes include running, rowing, skateboarding, kick scooters and roller skates. Due to its prevalence, cycling is sometimes considered separately from the other forms of active mobility.

Public policies promoting active mobility tend to improve health indicators by increasing the levels of physical fitness and reducing the rates of obesity and diabetes, whilst also reducing the consumption of fossil fuels and consequent carbon emissions. These policies are proven to result in large increases in active transportation for commuting: for example Portland, Oregon, was able to increase bicycle use 5-fold from 1990 to 2009 with pro-cycling programs. Studies have shown that city level programs are more effective than encouraging active mobility on the individual level.

Alternatives to the automobile[edit | edit source]


Current technological developments suggest that the present car system will be replaced. Established alternatives to the automobile include public transit (buses, trolleybuses, trains, subways, monorails, tramways), cycling, walking, rollerblading and skateboarding. W

Fly less[edit | edit source]

Common Destination: The World Is Changing. Aviation Needs to Change Too.

With freedom comes responsibility. Fly less cropped(46933214734).jpg

While air travel represents just about 2% of global emissions,[2] that's because only 4% of the world population flies regularly (at least once per year).[3] But for those that do fly, it typically makes up more than 50% of their carbon footprint! So if you fly regularly, reducing flights is probably the top way to cut your carbon emissions.

  • Give a chance to local destinations for holidays
  • Favor overnight trains or buses over short distances
  • Think harder whether you really need to go to that conference
  • Pay extra for shorter direct flights (your time is valuable too!)
  • Compensate your emissions
