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

The Group built its environmental management system based on ISO 14001:2015. Its subsidiaries (including CSCHK, China Overseas Building Construction Limited, China State Mechanical & Electrical Engineering Limited, Alchmex International Construction Limited, China State Civil Engineering Limited and China State Foundation Engineering Limited) successfully passed this reporting year’s internal and external audit. In addition, both CSCHK and COBC have passed the transfer audit of ISO 50001:2018 Energy Management System. CSFC also completed the new certification audit of the same system.

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

CSCHK established its environmental and resources management system in accordance with ISO 14001 and ISO 50001, forming a close-circuit management in planning, implementation, performance appraisal and improvement, as well as integrating green development into the daily operations of the company. As an important component in environmental management, the establishment and review of annual targets guide CSCHK in implementing its environmental management plan and measures, which also quantify its performance. In 2020, most construction sites and office buildings of CSHK met their environmental targets. Based on this performance, the company has established environmental targets and indicators for 2021:

Conducting Carbon Verification

The Group has engaged an external consultant for the first time during this Reporting Year to conduct GHG data verification in accordance with ISO 14064-3 “Greenhouse gases - Part 3: Specification with guidance for the verification and validation of greenhouse gas statements” to ensure the reliability and accuracy of GHG data. The GHG data verification process includes.

The Group has verified data from nine projects and plants in Hong Kong and mainland China for this year and is considering to expand the scope of data verification to other projects in the future to serve as a solid and reliable basis for setting GHG emissions reduction targets.
