CarbonCure secures Hong Kong approval, debuts at CENTRAL project

The approval unlocks low carbon concrete reducing cement content by up to 7%.

Hongkong Land and Gammon Construction have deployed CarbonCure’s carbon dioxide mineralisation technology in Hong Kong following approval of the concrete mix by the Buildings Department, marking its first use at the Tomorrow’s CENTRAL project.

The technology injects captured carbon dioxide during mixing, trapping carbon within the material and reducing cement content by 4% to 7% without affecting performance, Hongkong Land said in a press release.

The mix was implemented on site in November 2025 following approval from the Buildings Department in September 2025 after an 18-month testing and preparation period.

Industry research cited by the companies indicates that cement production accounts for about 7% of global carbon dioxide emissions, whilst more than 80% of embodied carbon in a typical new commercial building comes from concrete, brick, and steel.

Hongkong Land said embodied carbon accounted for 70% of its total emissions in 2025.

The CarbonCure mix, combined with a low-carbon formulation containing about 40% ground granulated blast-furnace slag, delivers a 34% reduction in carbon emissions compared with conventional concrete.

The deployment supports Hongkong Land’s Sustainability Framework 2030 and its target to reduce Scope 3 carbon intensity by 22%.

The Tomorrow’s CENTRAL project also targets the use of 100% low-carbon concrete, 100% green rebar, and 100% sustainable timber, and aims to divert 75% of construction waste.

Tomorrow’s CENTRAL is a three-year programme to upgrade the LANDMARK retail portfolio, including façade works, retail renovations, and office lift lobby relocations. Hongkong Land announced the project in June 2024.

Eddie Tse, Group Sustainability Manager at Gammon Construction, said the deployment enables the permanent mineralisation of carbon in building materials and reduces cement use.
