A group of property developers and construction firms in Hong Kong has come together to address the significant carbon emissions embedded within construction materials and the broader supply chain. These companies aim to implement industry-wide standards that prioritize the procurement of low-carbon materials as part of a broader climate-action initiative.
The group is working to create procurement guidelines and frameworks that focus on reducing emissions by promoting transparency and accessibility to low-carbon products. Industry experts emphasize that such measures are essential to encourage investments in sustainable materials and practices.
Key industry players argue that the construction sector faces challenges in accessing credible, low-carbon materials, highlighting a need for a standardized approach. Notably, 60 percent of Hong Kong’s carbon emissions are tied to electricity consumption in buildings, with significant portions also stemming from building materials and construction processes.
Efforts to drive change include setting ambitious carbon-reduction targets and launching technical guidelines that establish benchmarks for material composition, recycling content, and manufacturing carbon intensity. These guidelines also focus on boosting energy efficiency across supply chains.
While the local government has pledged to achieve carbon neutrality by 2050, current regulations fall short of addressing the embodied carbon emissions within construction materials. Innovators are working on solutions such as carbon-absorbing concrete and advanced construction techniques that could dramatically cut emissions, but without broader policy support, such efforts remain limited.
The collaboration among developers is seen as a vital step in advancing the use of sustainable materials, and the industry is calling for stronger policy incentives and a standardized approach to drive further progress.
