The construction industry in Hong Kong is witnessing a significant shift towards sustainability as Gammon Construction, in partnership with Hongkong Land, employs groundbreaking low-carbon concrete technology in the city's Landmark retail area. This move is part of a broader three-year project named Tomorrow’s Central, aimed at modernizing the Landmark's facade, office, and lobby spaces.
What Happened
Gammon Construction, a subsidiary of Balfour Beatty, is utilizing CarbonCure’s carbon dioxide mineralization technology to reduce the carbon footprint of concrete used in the Landmark project. This innovative approach involves injecting captured CO₂ into fresh concrete, where it undergoes a chemical transformation to form a mineral that permanently locks in carbon. The concrete mix also incorporates approximately 40% ground granulated blast-furnace slag, which reduces cement content by up to 7% without affecting performance. The Hong Kong Buildings Department approved this low-carbon concrete mix in September 2025 after an extensive 18-month testing period. Beyond concrete, the project also features sustainable construction techniques such as 100% green rebar and sustainable timber.
Why It Matters for the AECM Industry
For the architecture, engineering, construction, and manufacturing (AECM) sectors, this development marks a crucial advancement in sustainable construction practices. The use of low-carbon concrete can potentially reduce carbon emissions by 34% compared to conventional methods, offering a viable solution to one of the industry's most pressing challenges: lowering embodied carbon in building materials. This approach not only aligns with global sustainability goals but also sets a precedent for future projects. By adopting such technologies, firms can mitigate environmental impacts, adhere to stricter regulatory standards, and potentially reduce material costs. This initiative by Gammon Construction could stimulate competitive dynamics, encouraging other industry players to adopt similar sustainable practices.
What's Next
Looking forward, the successful implementation of this technology at the Landmark project could pave the way for broader adoption across Hong Kong and beyond. As Gammon Construction's Group Sustainability Manager Eddie Tse highlighted, the company aims to extend these innovations across the industry and collaborate with more clients to drive low-carbon construction in the region. Industry professionals should watch for further developments as the project progresses and additional sustainable construction methods are integrated. Monitoring policy changes and certifications related to sustainable materials will be crucial for staying competitive and compliant in this evolving landscape.
