Environmental Protection

As a responsible company, CNOOC Limited views lucid water and lush mountainous areas as invaluable assets. We have responded to climate change challenges by implementing the goal to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060. We have started the composition of the action plan for that goal and fully implemented our green and low-carbon development strategy through clean energy development, energy-saving and emission reduction projects and efficient energy utilization, fully committed to being a resource-saving green company.

Risk Assessment

CNOOC Limited supports the climate goals set in the Paris Agreement and fully understands the impact of climate change on the Company. We are working to meet this challenge by identifying and analysing the risks and opportunities brought about by climate change and responding with appropriate measures.

Energy Conservation

The Company is committed to the principle of “clean production, the use of harmless raw materials, resource recycling, and low carbon energy”. We support these principles by continuously promoting the construction of green manufacturing system. Our energy saving target——in 2022, it is expected to save149,800 tons of standard coal through the implementation of offshore oil and gas production platform power networking, pump frequency conversion transformation, flare gas recycling, and shore power replacement.

Water Resource Management

We have formulated policies and regulations such as the Rules for Water Conservation Management. Meanwhile, we have performed comprehensive water resources management by strengthening technological transformation and comprehensive treatment and reuse of wastewater, and carrying out tests on water balance and research on water-saving potential of enterprises. Our water conservation targets——by 2022, 25,000 tons of water is expected to be saved through source management and control of new projects, seawater desalination with waste heat, condensate water and rainwater collection, and optimised ship operation.

Low Carbon Management

Resolutely moving towards the goal of “carbon peaking and carbon neutrality” and adhering to the Measures for the Administration of Carbon Emissions Trading (for Trial Implementation), we are working on and improving our low carbon management systems., enhancing our energy-saving and low-carbon supervision and monitoring, participating in Carbon Quota Trading, developing CO2 Capture and Storage to push forward the green and low-carbon transition on an ongoing basis.

In 2021, by promoting technological transformation, we reduced 409 thousand tons of carbon emissions, effectively restraining the rapid growth in total carbon emissions. Our greenhouse gas emission reduction targets——by 2025, we plan to achieve a cumulative emission reduction of more than1.5 million tons of carbon dioxide equivalent.
