Cundall’s sustainability team in Hong Kong was appointed by the Construction Industry Council (CIC)to develop the Carbon Assessment Tool (CAT) as part of their wider sustainability strategy. This online tool is publicly available and designed to be used across the industry, from public owners, developers and designers, to contractors and suppliers. The CAT encourages carbon reduction through low carbon design and construction.
The CAT will collect data from projects, ultimately enabling carbon benchmarks for multiple typologies, e.g. commercial, residential, tunnel, highway, etc. Users will then be able to compare their performance against the benchmark. The data will also assist CIC with their annual reporting for the industry against the Hong Kong carbon reduction targets.
Two key focuses for CIC in the development of the CAT are the usability of the CAT and the suitability of the carbon emission factors for Hong Kong. It is therefore important to engage with the end-users throughout the development to ensure their feedback. Suggestions from users were considered in order to get their buy-in for using the CAT. We hosted numerous stakeholder engagement workshops with public owners, private developers, contractors, and material suppliers throughout the development process.
In order to measure the carbon footprints of these materials, the team used Hong Kong trade statistics and worked closely with materials suppliers to understand the materials’ source locations and developed the database to reflect this. Representative data sources were collected to develop a database reflecting the material type, recycled content, manufacturing process and source location of these materials. Generic numbers were also included for each material type in case users do not know the source location or specification of the materials used.
It is anticipated the integration of the CAT into BEAM Plus (Hong Kong Green Building Certification System) will drive industry buy-in as the scheme is widely used on building projects in Hong Kong. The CAT users can generate automated reports through this platform to aid other sustainability reporting, such as ESG reporting and carbon audits.
Through the launch of the CAT, it is hoped that it will drive the industry forward on the decarbonisation journey and facilitate the industry to realise the savings that can be made. For further details please start your journey on CAT Website: www.cat.cic.hk
