CREW Carbon is pleased to announce that we’ve delivered our first verified Wastewater Alkalinity Enhancement (WAE) carbon dioxide removal (CDR) credits to Frontier buyers. These initial 104.4 credits, verified by Isometric, mark the first delivery under our 6 year, $32.1 million offtake agreement with Frontier buyers including Frontier founders Stripe, Google, Shopify, and members Autodesk, H&M Group, Workday, Salesforce, Watershed, and JPMorgan Chase.
The credits were generated from CREW’s flagship, multi-kiloton project at the East Shore Water Pollution Abatement Facility operated by the Greater New Haven Water Pollution Control Authority (GNHWPCA), and represent a significant milestone for scaling carbon removal and demonstrating WAE’s potential as a carbon removal pathway.
This project will soon be one of the largest operating carbon removal projects on the East Coast of the U.S., integrating into a facility which processes 40 million gallons of wastewater per day. Located on the shore of the New Haven Harbor, the GNHWPCA oversees an extensive sewer system spanning over 555 miles of pipeline and 30 pump stations, which is all in service of keeping the local community and environment safe, including the Long Island Sound.
From our Co-Founder and CEO, Dr. Joachim Katchinoff, “Maximizing existing infrastructure and using proven science, CREW’s engineered enhanced weathering approach offers a cost-effective, highly measurable and globally scalable approach to durable carbon removal. In addition to providing an essential service to our communities, wastewater treatment plants are powerful places to remove CO₂. By integrating directly into existing infrastructure, CREW’s WAE technology transforms everyday facilities—like the East Shore Facility—into climate assets, delivering durable, measurable carbon removal while improving treatment efficiency, lowering OpEx costs, and helping operators protect the local environment. This milestone proves that carbon removal doesn’t need to wait – it’s already happening.”
