Environmental planning is a field of study that since the 1970s has been concerned with a given society's collective stewardship over its resources that ultimately includes those of the entire planet.The aims of environmental planning are to integrate the public sector urban planning with the concerns of environmentalism to ensure sustainable development, notably of air, water, soil and rock resources. Planning seeks to include into consideration for future growth of society factors other than those urban planners have traditionally factored in economic development, such as transportation, sanitation, and other services in legislator decisions, by working with environmental planners to add sustainable (social, ecological & equity) outcomes as important factors in the decision-making process.
