Our communities and infrastructure must be planned and built in the public interest, with transparent, evidence-based, accountable and participatory planning processes. Ecosystems and natural communities have an independent right to exist and flourish and this right must be recognised and upheld in planning processes. Rural and regional planning requires specialist knowledge and focus and should not be neglected in favour of metro-centric planning or short-term planning based on transitory industries.
Aims — Planning The Australian Greens want: Planning that is based on: a transition to a zero carbon economy; sustainable urban design principles including minimising urban sprawl; promoting development in mixed-use, compact communities; and climate adaptation to address flooding, drought and bushfires. Development that is affordable, ecologically sound, water and energy efficient, integrated with public transport, and fosters community interaction.
To reduce the spatial disconnection between residential and employment locations particularly for disadvantaged groups.
Improved integration of planning and transport aimed at better use of existing and planned infrastructure. Ecological sustainability and contribution to a safe climate as funding criteria for all federal development and infrastructure programs. A national report card for progress towards ecological sustainability targets in the built environment. Australian building standards to be improved, to address climate change impacts, and environmental and safety issues, and to improve the sustainability of the built environment. National urban planning standards that provide for the location of high density housing and commercial buildings close to high capacity public transport, and the clustering of medium-density housing, community facilities and small-scale businesses around neighbourhood shopping centres.
Spatial planning that harmonises local development and infrastructure solutions that support social equity, walkability, transport, food production, tree cover, biodiversity and habitats, in responding to energy, land and water supply pressures as part of a climate change adaptation strategy.

Arteries or transport terminals can define urban borders and produce segregation. Major transport facilities can affect the quality of urban life by creating physical barriers, increasing noise levels, generating odors, reducing urban aesthetic and affecting the built heritage.
The expansion of logistics activities has also been an indirect factor of land take in suburban and periurban areas. Externalities are an economic concept that refers to the activities of a group that have consequences , positive or negative, intended or unintended, on other groups. These consequences, particularly if they are negative, are not fully assumed by those causing them. The impacts are therefore externalized. A common example of a positive externality concerns technology since it obviously benefits the innovative firm but also the whole economy through various productivity improvements or improved convenience.
Negative externalities are highly relevant over environmental issues, since many of the negative consequences of pollution are assumed by the whole society. The environmental externalities of transportation include the consideration of physical measures of environmental damage and the evaluation of involved costs for the society. The main fallacy underlined by externalities is that the costs attributed to a few sources e.
Knowing the sources of environmental externalities is a relatively easy undertaking, while the evaluation of damage and other costs has not yet reached comparative standards among governmental and non-governmental agencies. The challenge resides over three issues:. The basic types of transportation externalities attributed to the environment fall within air pollution, water pollution, noise, and hazardous materials.
Establishing and quantifying environmental externalities is a complex undertaking. Quantification is only at its preliminary stage and many have used this argument to differ the application of several environmental policies by lobbying governments e.

Additionally, the wider the geographical scale the more complex the environmental problem becomes, since it involves cross-jurisdictional issues. Recent attempts to reach a consensus about climate change have underlined the complexity of multilateral environmental agreements. This has several implications. First, when specific sources are concerned, like road transportation, users only take account of the direct costs of modal ownership like a car vehicle, fuel, insurance, etc.
Ownership is often the only entry and utilization cost for several transportation modes.
The society generally assumes the role of providing and maintaining infrastructure and other indirect costs like damage to structures and infrastructure, losses in productivity, cleanup, health services and damage to ecosystems. Second, the geographic separation between sources and recipients is often acute.
Acid rains and climate change are obvious examples. On a local level, a community may be affected by noise levels well over its own contribution notably near major highways , while another e. There is a tendency towards a shift from direct to indirect consequences for environmental externalities , as of total costs involved. For instance, the absolute levels of air pollutants emissions have considerably dropped in developed economies.
The problem of source reduction by vehicles was addressed because it was a straightforward cause of air pollutants emissions. This has tended to displace problems elsewhere and developed new types of externalities. Thus, the relative share of air pollution impacts is lessening, but not the number of vehicles, investment in infrastructure or noise levels, which have their own externalities. Reductions in the relative importance of one type of externality redirect the focus on other types that were less addressed, but probably as important in the overall impacts of transport over the environment.
Transfers and additions of costs are very common attributes of environmental externalities. Trying to lessen economic costs will either lessen or worsen social and environmental costs, depending on the externality. In the context of limited resources, the distribution of economic, social and environmental costs takes an important role as what type of damage is acceptable and in what proportions. It is clear from past strategies that several economic costs have been minimized, notably for producers and users, while social and environmental consequences were disregarded.
This practice no longer applicable since the society is less willing to bear the costs and consequences of externalities for various reasons public awareness, quality of life considerations, high health costs, etc. Air pollution is the most important source of environmental externalities for transportation , mainly because the atmosphere enables a fast and widespread diffusion of pollutants. Although the nature of air pollutants is clearly identified, the scale and scope on how they influence the biosphere are subject to controversy.

On the positive side, emissions of the most harmful air pollutants, such as Carbon Monoxide and Volatile Organic Compounds, have declined in spite of a substantial growth in the number of vehicles, which is indicative of the growing levels of environmental compliance of vehicles. Carbon Dioxide emissions have increased proportionally with the growth of transportation usage.
Two major groups of factors are contributing to air pollution, notably in urban areas. Externalities related to water pollution are almost all indirect consequences. It is thus difficult to evaluate and to appraise the specific contribution of transportation over various environmental issues, which explains that problems tend to be addressed on a modal basis. Noise emissions can be represented as point a vehicle , line a highway and surface ambient noise generated by a set of streets sources. Noise pollution is only present as vibrations.
For instance, for a road vehicle, vibrations are created through the internal combustion engine, moving parts transmission and friction on the surface over which a transport mode moves.
The impacts of noise is strictly local, as vibrations are quickly attenuated by the distance and the nature of the landscape trees, hills, etc. A hazardous material is a substance capable of posing an unreasonable risk to health, safety, and property when transported in commerce. Considering the large amounts of freight being shipped through transport systems, hazardous materials have become a concern. Several hazardous materials hazmat releases are spectacular events, notably when it involves a supertanker or a train convoy.
However, we must consider that maritime transportation only accounts for 0.

Other transportation modes are thus important sources of hazmat release in the environment, even if they mostly involve small quantities. Very limited information is available on the nature and consequences of hazmats released during transportation, except for safety regulations. The effects of hazmat release are always punctual, but intense. The nature of the effect is related to the type of accident and the hazmat involved.

It can range from a small-scale accident where limited quantities of hazmat are spilled, to important accidents requiring prompt intervention and evacuation local residents. Externalities are also occurring at different geographical scales , and some may even overlap over several scales. The bottom line is that better transport practices, such as fuel-efficient vehicles, that reduce environmental externalities are likely to have positive economic, social and environmental consequences.
While the public sector is incited the address the environmental impacts of transportation through policies and regulations, the private sector deals with compliance and tries to innovate. This iterative process is complex but the environmental of transportation has been addressed more comprehensively. It remains to be seen about which strategy is the most beneficial as in all environmental matters much subjectivity and often ideology prevails. Author: Dr. Jean-Paul Rodrigue Transportation systems, from infrastructures to vehicle operations, have environmental impacts ranging from noise, the emission of pollutants to climate change.
These impacts fall within three categories: Direct impacts. The immediate consequence of transport activities on the environment where the cause and effect relationship are generally clear and well understood. For instance, noise and carbon monoxide emissions are known to have direct harmful effects. Indirect impacts. The secondary or tertiary effects of transport activities on environmental systems. They are often of higher consequence than direct impacts, but the involved relationships are often misunderstood and more difficult to establish.
For instance, particulates which are mostly the outcome of incomplete combustion in an internal combustion engine are indirectly linked with respiratory and cardiovascular problems since they contribute among other factors to such conditions. Cumulative impacts.

The additive, multiplicative or synergetic consequences of transport activities. They consider the varied effects of direct and indirect impacts on an ecosystem, which are often unpredictable. Climate change, with complex causes and consequences, is the cumulative impact of several natural and anthropogenic factors, in which transportation plays a role. The share of transportation in global CO2 emissions is increasing. The Transport — Environment Link The relationships between transport and the environment are multidimensional.
