Climate change has become a global threat with worrying consequences for many countries. Among various economic sectors, the construction industry consumes 40% of materials entering the global economy and generates significant amounts of greenhouse gases (GHG) - the main cause of climate change. The embodied carbon of construction materials used can contribute up to 25% of a building’s lifetime carbon footprint. It is thus highly desirable to minimise the GHGs emissions through the prudent selection of low carbon construction products.
Consequently, the Construction Industry Council (CIC) initiates the Carbon Labelling Scheme for Construction Products (the "Scheme") as part of our mission to promote green building practices and sustainable development. The Scheme aims to provide the communication of verifiable and accurate information on the carbon footprint of construction products for client bodies, designers, contractors and end users to select 'low carbon' materials. As a Hong Kong-based voluntary scheme, it intends to encourage the demand for, and supply of, low carbon products, thereby contributing to Hong Kong's transition to a low carbon economy.
The Scheme focuses on a single impact category: climate change by quantifying the GHG generated from the production of construction material in terms of CO2 equivalents (CO2e). It covers six types of GHGs cited in the Kyoto Protocol (United Nations, 1997), namely, CO2, methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6) which impact directly on global warming. Initially, it covers three categories of carbon-intensive construction products: Cement, Reinforcing Bar, and Structural Steel. In September 2014, a newly developed category is released and opens for application now: ready-mixed concrete (click here to download the relevant Assessment Guide and Tool). Additional product categories will be covered under the Scheme in due course.
The Scheme is administered by Zero Carbon Building (ZCB). Click here to contact us for enquiries.
