The cars emit the greenhouse gasses such as carbon dioxide which contribute in the global warmingSome air pollutants and particulate matters from the cars can be deposited on the soil and the water surface where they enter the food chain that can affect the reproductivethe respiratorythe immune and the neurological systems of animals. Lead is a pollutant that produced from burning leaded fuel, interferes with normal red blood cell creation by reducing important enzymes in the body, Lead damages the red blood cell membranes and it obstructs with the cell metabolismit shortens the lifespan of each individual cell and all of these harmful effects can cause Anemia.
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 The environmental impacts of automobiles 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.
The Transport — Environment Link The relationships between transport and the environment are multidimensional. Some aspects are unknown and some new findings may lead to drastic changes in environmental policies. Historically, transportation was associated with a few negative environmental impacts.
For instance, the setting of large navies of sailships was responsible for a level of deforestation in Western Europe and North America from the 16th to the 19th centuries. Urbanization in the 19th century and the reliance on horses created problems concerning the disposal of manure. Further, industrialization and the development of steam engines lead to pollution e.
It is however only in the 20th century that a comprehensive perspective about the links between transportation and the environment emerged, particularly with the massive diffusion of transportation modes such as the automobile and the airplane. The s and s were crucial decades in the realization of the negative environmental impacts of human activities and the need for regulations.
From an infrastructure perspective, the first comprehensive environmental regulation, the National Environmental Policy Act NEPAwas set in and required all federal agencies of the US government to make environmental impact assessments of their actions.
Since an agency such as the Department of Transportation is an important provider and manager of transportation infrastructure, this legislation had substantial impacts on how transportation is assessed to be linked with environmental issues. One clear consequence was the growth in the length and the complexity of approving transport infrastructure projects to insure they meet environmental standards.
Opponents of a project could also use the regulatory framework to delay, or even cancel its construction and on occasion change its design parameters e. An unintended consequence was that the complexity of environmental regulations tend to impair innovations and incite current providers to keep existing infrastructure and facilities for the concern to trigger an uncertain environmental review with a new project.
From an operational perspective, the Clean Air Act of set clear air quality standards and expectations for both stationary e.Packaging technology must balance food protection with other issues, including energy and material costs, heightened social and environmental consciousness, and strict regulations on pollutants and disposal of municipal solid waste.

And if your EV is powered by coal, as is the case in many U.S. locations, it will actually cause an increase in environmental impacts of 17 to 27 percent as compared with a conventional car.
The impact of the automobile and the auto-centered transport system on the American environment has been enormous. From the manufacturing process to the junkyard, cars—and all motorized vehicles for that matter—consume resources; pollute the air, land, and water; and transform space.
