The Environmental Policy and Planning Group (EPP), located in the Department of Urban Studies and Planning (DUSP) at MIT, seeks to improve the way society conserves and manages natural resources and pursues sustainable development, particularly (though not exclusively) in urban and metropolitan settings around the world. Some specific areas of research and teaching include the adoption and diffusion of technologies that aim to mitigate or remediate environmental problems, particularly renewable energy, energy-efficiency, and water-conservation technologies; the efficacy of efforts to prevent and reduce air and water pollution and manage the disposal of toxic and hazardous wastes; the prospects for international, national, state-level, and local strategies for mitigating and adapting to climate change; the resolution of conflicts surrounding facility siting and the allocation of transboundary water resources; the pursuit of environmental justice; and the development of more flexible forms of urban infrastructure.
