As an industry pioneer, we are making a solemn commitment to "actively explore the first hydrogen energy application pilot in the Hong Kong construction industry and introduce hydrogen energy as one of the energy supplies on the construction site." This strategic initiative not only demonstrates our concrete efforts in addressing climate change but also highlights our determination to lead the industry towards a low-carbon future. The three major carbon reduction commitments we proposed serve as crucial steps towards achieving sustainable development objectives and reflect the Company's leadership in the field of clean energy applications.

In 2024, CSHK successfully obtained approval to deploy hydrogen power generators at the Hong Kong-Shenzhen Innovation and Technology Park construction site project, marking a milestone breakthrough. As the pioneering utilization of hydrogen power generation equipment in the construction sector, it sets an innovative benchmark for the industry.

Green Building Materials and Technologies


In our efforts to advance sustainable development in the construction sector, the application of green building materials and the integration of innovative technologies have emerged as crucial components in achieving environmental protection objectives. CSHK is committed to integrating sustainable materials with advanced construction technology, comprehensively enhancing the environmental performance of buildings throughout their entire lifecycle from inception to operation by optimizing resource efficiency, minimizing carbon footprints, and improving construction efficacy. Through tangible initiatives, we demonstrate synergy between environmental protection and operational efficiency, setting a benchmark for sustainable construction in the industry.

Low carbon reinforced steel bar

  • 100% recycled content
  • The carbon reduction potential reaches 67%
  • The total usage of low-carbon steel bars is 437 tonnes
  • Reduce energy use by 74% and lower air pollution by 86% compared to traditional blast furnace processes

GGBS concrete

  • Using GGBS concrete instead of cement can reduce 53% carbon emissions
  • A total of 14,670 cubic meters of GGBS concrete were used
  • The proportion of GGBS concrete in the total concrete usage increased from 0.2% in 2023 to 1% in 2024

Biodiesel

BIM

BIM technology is the core foundation for achieving intelligence in the construction industry. This technology is based on multidimensional data from construction projects, utilizing computer-aided design to construct three-dimensional digital building models that fully simulate the physical building information system. By systematically recording and deeply analyzing complex working conditions, the dynamic data of the construction site is fully digitized, enabling real-time decision-making and precise control by the management.

MiC

The Modular Integrated construction (MiC) method involves prefabrication standardized components in factories, which are carried out simultaneously with the early construction of the site. Over 89% of the decoration is completed in the factory, reducing the construction period by at least 25% compared to traditional construction methods. Correspondingly, the overall energy consumption, water usage, and wastewater discharge are also significantly reduced by 25%.

MiMEP

CSHK adopts the Multi-trade Integrated Mechanical, Electrical and Plumbing, prefabricating integrated mechanical and electrical modules in factories. Integration of electromechanical facilities into modular components, fabrication of components and preassembly in the plant will increases productivity, significantly shortens the construction cycle and reduces the complexity of on-site installation.
