HKCA launches new guidelines for carbon-smart construction sites

The HKCA also launched the Carbon Smart Construction Site Labelling Scheme.

The Hong Kong Construction Association (HKCA) has launched the Best Practice Guideline for Carbon Smart Construction Site, focusing on decarbonisation, assisting contractors in formulating carbon reduction strategies and optimising relevant processes.

The HKCA collaborated with the Business Environment Council Limited (BEC), introducing a ‘4M1E’ framework (Man, Machinery, Materials, Methods, and Environment), which categorises 36 smart low-carbon measures.

In Manpower, it encourages the use of digital management platforms and Building Information Modelling (BIM) to optimise decision-making and processes.

Meanwhile, in Machinery, it promotes the application of electric construction machinery and temporary power supply, reducing reliance on traditional diesel generators.

Further, in Materials, it advocates the use of low-carbon concrete and recycled materials, whilst in Methods, it introduces digital material management systems, prefabrication technology, and mixed reality platforms.

In the Environment, it promotes the adoption of renewable energy systems and site wastewater recycling measures.

The HKCA also launched the Carbon Smart Construction Site Labelling Scheme, aiming to commend sites that demonstrate outstanding performance in carbon reduction.

The label scheme quantifies the carbon reduction impact and scores them with carbon reduction tokens.
