STACK Infrastructure has taken a first step toward greener construction in the data center sector by testing ultra-low-carbon cement from Sublime Systems at its Prince William County, Virginia campus. The trial marks the inaugural use of Sublime’s electrochemically produced cement in the industry.
The pilot involved pouring the material for a section of a high-traffic loading dock to evaluate its long-term performance. Early results, including compressive strength tests, have surpassed expectations.
“With STACK among the most innovative and forward-thinking data center developers, the piloting of carbon-avoiding Sublime Cement is a powerful validation of our technology in the infrastructure that is essential for enabling the digital economy,” said Dr. Leah Ellis, CEO and Co-founder of Sublime Systems.
“Across the many concrete applications in a data center, loading docks endure significant wear and stress, making this placement perfect for showcasing the superior durability of Sublime Cement.”
Part of a Broader Net-Zero Push
The initiative comes amid rapid data center expansion driven by AI and heightened demand for digital infrastructure.
STACK says aligning that growth with climate targets is essential, making low-carbon construction materials a key strategy.
Alongside this pilot, the company is pursuing other methods to reduce embodied carbon, such as higher use of supplementary cementitious materials (SCMs) and integrating mineralized CO2 solutions.

By combining local partnerships with innovative building practices, STACK aims to set a benchmark for sustainable data center development while moving toward its Net Zero goals.
“As the first deployment of Sublime’s low-carbon cement in a data center application, it marks a milestone for the industry. It sets a new standard not only in how we build, but in how we lead, with tangible benefits for the environment, our clients, and the local communities we serve,” said Bethany Brantley, Head of Sustainability, STACK Infrastructure.
