=== Environmental ===
The built environment has a multitude of impacts on the planet, some of the most prominent effects are greenhouse gas emissions and Urban Heat Island Effect.<ref>{{Cite web |last=US EPA |first=OW |date=2015-10-01 |title=Reduce Urban Heat Island Effect |url=https://www.epa.gov/green-infrastructure/reduce-urban-heat-island-effect |access-date=2024-01-24 |website=www.epa.gov |language=en}}</ref>

The built environment expands along with factors like population and consumption which directly impact the output of greenhouse gases. As cities and urban areas grow, the need for transportation and structures grows as well. In 2006, transportation accounted for 28% of total greenhouse gas emissions in the U.S.<ref name=":15">{{Cite journal |last1=Younger |first1=Margalit |last2=Morrow-Almeida |first2=Heather R. |last3=Vindigni |first3=Stephen M. |last4=Dannenberg |first4=Andrew L. |date=2008-11-01 |title=The Built Environment, Climate Change, and Health: Opportunities for Co-Benefits |url=https://www.ajpmonline.org/article/S0749-3797(08)00682-X/abstract |journal=American Journal of Preventive Medicine |language=English |volume=35 |issue=5 |pages=517–526 |doi=10.1016/j.amepre.2008.08.017 |pmid=18929978 |s2cid=35151432 |issn=0749-3797|url-access=subscription }}</ref> Building's design, location, orientation, and construction process heavily influence greenhouse gas emissions.<ref name=":15" /> Commercial, industrial, and residential buildings account for roughly 43% of U.S. {{CO2}} emissions in energy usage.<ref name=":15" /> In 2005, agricultural land use accounted for 10–12% of total human-caused greenhouse gas emissions worldwide.<ref name=":15" />

[[Urban heat island]]s are pockets of higher temperature areas, typically within cities, that effect the environment, as well as quality of life.<ref name=":16">{{Cite web |last=US EPA |first=OAR |date=2014-06-17 |title=Learn About Heat Islands |url=https://www.epa.gov/heatislands/learn-about-heat-islands |access-date=2022-12-16 |website=www.epa.gov |language=en}}</ref><ref>{{Cite web |last=US EPA |first=OAR |date=2014-06-17 |title=Heat Island Impacts |url=https://www.epa.gov/heatislands/heat-island-impacts |access-date=2022-12-16 |website=www.epa.gov |language=en}}</ref> Urban Heat Islands are caused by reduction of natural landscape in favor of urban materials like asphalt, concrete, brick, etc.<ref name=":16" /> This change from natural landscape to urban materials is the epitome of the built environment and its expansion.
