The Mayor's Office of Environmental Coordination (MOEC) assists City agencies in carrying out their environmental review responsibilities and contributes to making New York City healthier and more sustainable. In addition to being the repository for all City Environmental Quality Review (CEQR) documents, MOEC serves as the City's liaison to state and federal agencies on environmental matters, coordinates the City’s brownfields efforts, administers the City’s green building program, and advises the Mayor on matters of environmental policy. OEC’s mission is to be a resource for city agencies and private applicants by providing information and assistance in completing the environmental review process and to help the city to lead by example in applying state-of-the-art green building requirements.
