others are a concrete plan for implementation. In the United States, for any project, environmental planners deal with a full range of environmental regulations from federal to state and city levels, administered federally by the Environmental Protection Agency. A rigorous environmental process has to be undertaken to examine the impacts and possible mitigation of any construction project was Depending on the scale and impact of the project, an extensive environmental review is known as an Environmental Impact Statement (EIS), and the less extensive version is Environmental Assessment (EA). Procedures follow guidelines from National Environmental Policy Act (NEPA), State Environmental Quality Review Act (SEQRA) and/or City Environmental Quality Review (CEQR), and other related federal or state agencies published regulations. Eccleston has developed a set of tools and techniques for solving NEPA and environmental planning problems. A study found that the best may to minimize information asymmetry and goal incongruence between organizations working to implement environmental policy is to focus on principle-agent dynamics thus avoiding conflict and allowing for progress in addressing environmental issues. The Association of Environmental Professionals (AEP) is a non-profit organization of interdisciplinary professionals including environmental science, resource management, environmental planning and other professions contributing to this field. AEP is the first organization of its kind in the US, and its influence and model have spawned numerous other regional organizations throughout the United States. Its mission is to improve the technical skills of members, and the organization is dedicated to "the enhancement, maintenance and protection of the natural and human environment". From inception in the mid-1970s the organization has been closely linked with the maintenance of the California Environmental Quality Act (CEQA), due to California being one of the first states to adopt a comprehensive legal framework to govern the environmental review of public policy and project review. Leadership in Energy and Environmental Design (LEED) in the major qualification system for green building. It is a certification system created by the U.S. Green Building Council (USGBC) and is used worldwide. The program includes certifications for new types of buildings as well as existing building that are candidates for modification. The multi-tiered point system enables building to be certified beyond local, state and federal standards. LEED standards play an important role in quantifying a building's environmental impact, encouraging sustainable environmental practices, and acting as a hybrid between "material objects and human practices."
