Environmental Management

CSCI’s Commitment

  • Complying with statutory, contractual and other requirements in all respects
  • Preventing environmental pollution
  • Reducing construction wastes
  • Minimizing the consumption of natural resources
  • Improving its overall performance

Environmental Management System

To more effectively manage environmental issues in business operations, the Group has established an environmental management system and related standard operating procedures. The Group’s Sustainability Policy outlines its approach to managing key environmental issues such as the treatment of emissions, the use of resources, the conservation of natural resources, and climate change. In addition, the Group strictly complies with environmental laws and regulations, contracts, and other relevant requirements to reduce construction waste and natural resource consumption, preventing environmental pollution. To establish an environmental management system more tailored to the operational location, the Group requires all subsidiaries to comprehend the environmental characteristics and needs of their respective locations, so as to implement specific management strategies that meet the requirements. The Group continues to consolidate and improve its management systems and mechanisms, and implements environmental protection measures in its daily operations. Environmental management systems within the Group are in accordance with ISO14001:2015, and its main subsidiaries have successfully passed internal and/or external audits within the past year to ensure the effectiveness of these systems.

Through the environmental management system, the Group specifies the leadership function, and the responsibilities and authority of employees involved in environmental management. We also require all units to analyse the main environmental factors in their operations and keep up-to-date with the latest development of local environmental regulations and standards. Environmental targets and indicators are developed to formulate a well-directed environmental plan and allocate appropriate budgets for environmental measures to continuously improve the Group’s environmental performance.

Case Study

Environmental Management of CSCHK

Based on the Guidelines for the Calculation of Environmental Indicators and the procedures for the Control of Materials Shrink, CSHK has set environmental indicators and targets, and set resource conservation targets for the Hong Kong Headquarters, which will be reviewed and approved by the Group’s General Management Committee.

Conducting Carbon Verification

To ensure the reliability and accuracy of GHG data, the Group continues to engage external consultants this year, the British Standards Institution (BSI), to verify GHG data in accordance with ISO 14064-3 Greenhouse gases — Part 3: Specification with guidance for the verification and validation of greenhouse gas statements. The GHG data verification process includes:

The Group has verified data for 10 projects in Hong Kong, Macao, and mainland China during the reporting period(2022), and is considering expanding the scope of data verification to other projects in the future.



Environmental Protection Promotion Activities

In June, the "2023 Environmental Protection Day" of China State Construction Engineering (Hong Kong) Limited was held. 33 employees visited the Tuen Mun Eco Park and WEEE▪Park to gain an in-depth understanding of the operation process of recycling and processing waste electrical and electronic products and how to "turn waste into materials" through detoxification, disassembly and recycling of "four electrical appliances and one computer", reduce waste disposal and promote low-carbon living.

An expired helmet recycling event was also held. Through the relevant activities, frontline workers were reminded of the importance of the validity period of helmets, and expired helmets were recycled and sent to recycling companies for processing and conversion into plastic materials to "turn waste into materials" to avoid being transported to landfills for disposal, reducing related carbon emissions. A total of 1,628 expired helmets were recycled during the event, breaking the 2022 recycling record.
