Environmental Protection

CNOOC Limited insists on “Environment Paramount” by strictly controlling the red line of ecological protection with environmentally friendly development. We also conduct marine ecological protection work to create harmony and achieve mutual benefits between individuals and the oceans.

As a developer of offshore oil and gas resources, a protector of marine ecology and a promoter of marine modernization, the Company adheres to the principle of "prioritizing ecological protection" and abides by the red lines of ecological protection. We insist on "paying equal attention to environmental protection and resource development" and attach great importance to the protection of biodiversity around the oilfields, striving for the harmony between production and operations and the nature.

Pursuant to the requirements of the Circular of the State Council on Printing and Issuing the Program of Aquatic Living Resources Conservation in China and the Technical Regulations for Impact Assessment of Construction Projects on Marine Living Resources, the Company has formulated the Measures for Ecological Environmental Protection, the Management Rules for Ecological Protection and Pollution Prevention and Control and other natural resource and raw materials management policies. The principle of "prioritizing ecological protection" shall be followed in project construction and operations, the full-life cycle eco-environment protection performance of the project shall be assessed and supervised, and effective ecological restoration programs shall be developed under the guidance and supervision of relevant government departments.


·      In the preliminary design stage of projects, we strictly observe the red line for ecological protection. For major construction projects where infringement on the red line is inevitable, efforts will be made to minimize the disturbance to the ecological environment. When developing the construction operation plan, the key protection period or sensitive period of environmentally sensitive area should be fully considered to avoid scheduling submarine pipeline/cable laying, ditching and other operations that disturb the ecological environment during these periods.

·      During the project construction and operation, the emissions and concentration of pollutants are strictly controlled to reduce the scope and extent of the impact on the marine environment. Monitoring plans for pollutants generated from projects are established to ensure that the discharged pollutants meet corresponding standards.

·      After the completion of the project, we take appropriate measures of ecological restoration, reclaim or compensation for the loss of marine biological resources caused by our projects, such as artificial propagation and release, fishery resources conservation and management and artificial reef construction, to realize restoration and sustainable utilization of fishery resources.

CNOOC Foundation of Marine Environment and Ecological Protection Protect the Marine Ecosystems through Multiple Measures

In 2023, CNOOC Foundation of Marine Environment and Ecological Protection (“CNOOC Foundation”) invested about RMB 18 million in environmental management research, ecological research, species monitoring, environmental protection publicity and other areas, which dedicated to ecological and species conservation.

The CNOOC Foundation has contributed to a number of biodiversity conservation activities, including the marine conservation conference, ecological protection day, knowledge exhibitions and other science popularization activities, and has organized fish fry releases and animal rescue and release. It has also funded multiple research projects on ecological protection, made great efforts to promote the research and development on marine biodiversity protection, and contributed to the maintenance and restoration of the marine ecosystem.
