Cities are the summation and densest expression of infrastructure, or more accurately a set of infrastructures sometimes working in harmony, sometimes with frustrating discord to provide us with shelter, contact, energy, water and the means to meet other human needs. The physical infrastructure of cities consists of various structures, buildings, pipes, roads, rails, bridges, tunnels, and wires. Equally important and subject to change is the “software” for the physical infrastructure, all the formal and informal rules for operation of the system. Moreover, millennia of human development show how much we owe to the necessity of mobility to move within and between cities.
The PHE investigates the technologies and infrastructures necessary for the development of human settlements and transport systems that conserve resources, emit zero pollutants, spare the surface landscape, and provide people with expanded range.

The purpose of the present study is to compare the environmental impacts of using coarse natural aggregate (NA) and coarse recycled concrete aggregate (RCA) to produce concrete in the New York City area, by means of a unique LCA framework that incorporates comprehensive regional data.
