摘要：How can a regulatory agency with historic roots in controlling pollution implement sustainability? How does an agency organized by individual media offices for air, water, toxics, and waste develop an integrated systems approach to environmental protection? Aligning and integrating programs is crucial for sustained environmental protection, especially in urban areas. The role of the U.S. Environmental Protection Agency (EPA) extends beyond setting national standards for air and water, protecting against chemical discharges, and restoring contaminated lands. The agency has the potential to become a national environmental architect by promoting research and innovation targeted at urban sustainability. To develop tools for creating a truly sustainable urban environmental infrastructure, EPA must develop approaches for adapting to potential climate change impacts on urban systems. In short, EPA needs an urban environmental strategy.
