Sustainability refers to activities that take into account their impact on other living things on the earth. Efficient utilization of resources such as land and building materials is essential to ensure adequate future housing supply. The ultimate goal is sustainable housing which tries to strike a delicate balance between comfort and performance efficiency. The success of sustainable housing plans depends upon the cooperation among various stakeholders including real estate developers, home buyers, land owners, transporters, and housing organizations. There are numerous ways to promote sustainable housing development such as using environmentally conscious design techniques, using sustainable energy sources, using recyclable materials, and employing efficient waste management processes. In order to promote the construction of green buildings in New York, Leadership in Energy and Environment Design (LEED) system has been developed. Similarly, New York’s construction and property sectors have also embraced Building Research Establishment Environmental Assessment Method (BREEAM) to assess the environmental performance of old and new buildings. New York’s subway system also needs to be modernized to reduce traffic congestion and environmental pollution.
