New York City is partnering with NYU and Rutgers University to study embodied carbon across the construction lifecycle. The research focuses on emissions from the production, transport, and installation of materials like steel and concrete to establish a baseline for new building standards. The initiative aims to cut the city's construction carbon footprint in half by 2033. By optimizing designs to use fewer materials and adopting low-carbon alternatives, the city intends to lower overall greenhouse gas emissions from the building sector.

Baseline studies are fine, but the real hurdle is the supply chain. Contractors wont switch to low carbon concrete if the local plants cannot provide it at scale or if the curing times mess up the project schedule.

That is why the procurement rules matter more than the study. If the city mandates these materials in public contracts, it creates the guaranteed demand needed for suppliers to invest in the tech.

Interesting that they mention 2 million metric tons from 2020. I wonder how much of that is actually material production versus the diesel burned by heavy machinery on site. The fix for those two things is completely different.

NYC is finally looking at embodied carbon instead of just operational energy. Most buildings are efficient once they are done, but the carbon hit from the steel and cement is locked in the day they are built.
