WS Development and Sublime Systems, in Collaboration with the White House, Gather Public and Private Sector Leaders for Ribbon Cutting to Celebrate Pioneering Low-Carbon Cement Construction Projects

Ceremony speakers included Massachusetts Governor Maura Healey, GSA Administrator Robin Carnahan, U.S. Chief Sustainability Officer Andrew Mayock, U.S. Representatives Richard Neal and Ayanna Pressley, Boston Mayor Michelle Wu, United Steelworkers International VP Emil Ramirez, and more

BOSTON, October 04, 2024–(BUSINESS WIRE)–On October 1^st leaders dedicated to advancing low-carbon cement as tool for reducing the built environment’s massive share of global CO₂ emissions (about 40%) gathered to celebrate the first commercial installations of Sublime Systems’s technology, in Boston’s largest net-zero-carbon office building, recently completed by WS Development in Boston’s Seaport. Local, state, and federal officials convened with executives representing union labor and the construction industry at One Boston Wharf, to unveil the first sidewalk made with low-carbon Sublime Cement™, following an earlier integration in the building’s interior concrete lobby.

In a transaction announced in 2021, Amazon has leased the entirety of the office space within One Boston Wharf, creating a total footprint of over 1 million square feet within WS Development’s expansive 33-acre Boston Seaport development. One Boston Wharf is reducing greenhouse gas emissions by more than 90% below code requirements and eliminating 5.1 million pounds of CO₂ emissions annually.

Founded in 2020, Sublime Systems is commercializing breakthrough, “true zero” manufacturing technology that avoids both the mineral and fossil fuel emission sources characteristic of portland cement. Its electrochemical process runs at near-ambient temperature and uses clean electricity and carbon-free inputs to produce reactive cementitious ingredients that are highly engineered for an optimally performing cement in concrete.

The distinguished speakers at the ribbon cutting collectively addressed the need for low-carbon cement in fighting the climate crisis; how the local, state, and federal government can accelerate this transition as they collectively consume more than 50% of the cement in the U.S.; the climate tech leadership of Boston and Massachusetts; the early movers in the construction industry; the role of union labor in supporting the new clean economy; and the policy ambitions of the Biden-Harris Administration enabling the pursuit of these broad ambitions in tandem.

Highlights of the day’s remarks include:

“In the finest revolutionary traditions of our fair city, we say: a step on our floor made of Sublime Cement™ is a step toward our carbon-free future, and a step heard ‘round the world,” said the event’s host, WS Development SVP of Development Yanni Tsipis, as he kicked off and introduced the lineup of speakers.
