Environmental planning
Environmental planning is a relatively new field of study that aims to merge the practice of urban planning with the concerns of environmentalism. Essentially speaking, while urban planners have traditionally factored in economic development, transportation, sanitation, and other services into their decisions, environmental planners add sustainable (social, ecological & economic) outcomes as important factors in the decision-making process. What exactly constitutes the "Environment", however, is somewhat open to debate among these practitioners, as is the exact scope of the intended environmental benefits. Chief concerns among environmental planners include the encouragement of sustainable development, green building technologies, and the preservation of environmentally sensitive areas.
