Carbon Footprint Reduction by Ernest Maier with CarbonCure Concrete Masonry Units

MGM National Harbor is targeting LEED Gold under LEED for New Construction version 2009. Green technologies will be visible and celebrated within the design. The project team is placing a large emphasis on transparency and disclosure of the project’s building materials.

The amount of CO₂ recycled in the CMU used in the MGM National Harbor Project is equivalent to the amount of CO₂ sequestered by 1.2 acres of U.S. forests in one year.


“In coordination with MGM Resorts International, SmithGroupJJR specified Ernest Maier with CarbonCure concrete masonry for the MGM National Harbor because the product’s reduced carbon footprint aligned with the project and client’s sustainability.”
