There can be no sustainable development without sustainable transportation. It is an essential component not only because transportation is a prerequisite to development in general but also because transportation, especially our use of motorized vehicles, contributes substantially to a wide range of environmental problems, including energy waste, global warming, degradation of air and water, noise, ecosystem loss and fragmentation, and desecration of the landscape. Our nation's environmental quality will be sustainable only if we pursue transportation in a sustainable way.

In the past few years, owners of contaminated land, seeking to supplement possible causes of action under the Comprehensive Environmental, Response, Compensation, and Liability Act (CERCLA) and under state common law and state statutes, increasingly have looked to §7002(a)(1)(B) of the Resource Conservation and Recovery Act (RCRA) to shift responsibility for remediation costs to former owners or operators.

If we want to think about changes in local sustainability over the last 10 years, perhaps the best place to start is with Al Gore. In 1992, just before the Rio Earth Summit and before he was to be tapped as a vice presidential candidate, then-Senator Gore published a treatise on the environment called Earth in the Balance.
