Hello CLF Team - What is the lowest embodied carbon CMU block available in the North Atlantic region with and without a cost premium? This is for a NYC project. Thank you (again), Aaron
I am not sure of its availability in your region, but have you heard of Prometheus Materials? They have a one-pager brochure for CMU
Unfortunately, it appears only on the west coast’ish region but there is also Basalite
Jandris CarbonX is a popular product in the Northeast and I believe it’s manufactured here. Bit of a pain to get the EPD though - you’ll have to contact them or it’s in the OneClick database.
Hi! Glenwood Masonry in Brooklyn makes block with Pozzotive and Carbon Cure. Pretty good stats. Light weight block as the best reductions in GWP though as to be expected (for now!)
You’ve gotten some good responses so far, but you can also find info from the Concrete Masonry and Hardscapes Association’s (CMHA) new-ish IW EPD at Sustainability - Concrete Masonry and Hardscapes Association. They have industry wide data for US and Canada. Unfortunately, they don’t have it broken out my region, but a couple of the companies listed in other posts share companies in the Eastern US.
