Transportation affects every part of our lives.
The air we breathe, the non-renewable energy resources we consume, our health and safety, the livability of our communities, and our impact on ecosystems are all directly linked to the transportation systems we use. The direct relationship between motorized modes of transportation, air pollution and the consumption of non-renewable energy resources are the most obvious impacts of our decisions. Sustainability involves designing transportation systems that improve environmental quality, protect ecosystems, minimize the consumption of non-renewable resources, provide for our commuting needs, and improve the quality of life in our communities. The I s and S s are followed by a brief statement of societal, economic and environmental benefits. For footnotes, reference individual reports.
