The Port Authority of New York and New Jersey this week announced its new low-carbon concrete program, setting caps intended to reduce carbon emissions by 37% immediately and work toward its goal of becoming carbon neutral.
The port authority’s requirements mandate sustainable concrete mixes in all future construction projects, including the use of ground glass and portland limestone cement within mixtures.
The decision is the result of a three-year study collaboration between the port authority and academics at Rutgers University, New Jersey Institute of Technology, Princeton University and New York University to create and test the results of different materials within mixes. The partnership identified 18 “recipes” that significantly reduce carbon emissions.
According to an article in New Jersey Business magazine, the port authority’s next steps are to test these mixes within projects that do not directly affect operations or safety.
