The Environmental Impacts of Transportation Author: Jean-Paul Rodrigue Transportation systems, from infrastructures to vehicle operations, have environmental impacts ranging from noise, the emission of pollutants to climate change.

From one side, transportation activities support increasing mobility demands for passengers and freight, while on the other, transport activities are associated with growing levels of environmental externalities. Further, environmental conditions have an impact on transportation systems in terms of operating conditions and infrastructure requirements such as construction and maintenance see Transportation and Space for a review of such constraints.

The growth of personal and freight mobility in recent decades have expanded the role of transportation as a source of emission of pollutants and their multiple impacts on the environment. These impacts fall within three categories: The immediate consequence of transport activities on the environment where the cause and effect relationship is generally clear and well understood.

For instance, noise and carbon monoxide emissions are known to have direct harmful effects. 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.

The additive, multiplicative or synergetic consequences of transport activities. They take into account of the varied effects of direct and indirect impacts on an ecosystem, which are often unpredicted.

Climate change, with complex causes and consequences, is the cumulative impact of several natural and anthropogenic factors, in which transportation plays a role. The complexities of the impacts have led to much controversy in environmental policy, the role of transportation and mitigation strategies.

This is made even more complex by the fact that priorities between environmental and economic considerations shift in time. The transportation sector is often subsidized by the public sector, especially through the construction and maintenance of road infrastructure, which tend to be free of access.

Sometimes, public stakes in transport modes, terminals and infrastructure can be at odd with environmental issues. If the owner and the regulator are the same different branches of the governmentthen there is a risk that regulations will not be effectively complied to.

Total costs incurred by transportation activities, notably environmental damage, are generally not fully assumed by the users.

The lack of consideration of the real costs of transportation could explain several environmental problems. Yet, a complex hierarchy of costs is involved, ranging from internal mostly operationscompliance abiding to regulationscontingent risk of an event such as a spill to external assumed by the society.

If environmental costs are not included in this appraisal, the usage of the car is consequently subsidized by the society and costs accumulate as environmental pollution. This requires due consideration as the number of vehicles, especially automobiles, is steadily increasing.
