The planes, trains, and automobiles used to transport people, goods, and services need to become more efficient, more equitable, and less environmentally disruptive, according to a three-year study by researchers from the Massachusetts Institute of Technology (MIT) and the Charles River Associates. Sponsored by the World Business Council for Sustainable Development in collaboration with General Motors, Shell, and Toyota, the $11 million Mobility 2001 report acknowledges that the world’s mobility systems are “significant contributors to congestion, deaths, injuries from accidents, climate change, resource exhaustion, public health problems . . . and ecosystem collapse.” It points out that some of the world’s most important challenges will take place in developing nations, where vehicle emissions of pollutants are high—and rapidly rising.
