Resource use

The Company is committed to conservation of energy and resource and development of circular economy. In strict compliance with the requirements under Energy Conservation Law of the PRC, various management systems have been formulated, such as Administrative Measures for Energy Conservation and Emission Reduction, Implementation Rules for Monitoring Energy Conservation and Emission Reduction and Implementation Rules for Water Conservation Control. There is designated management departments currently in place for energy saving and emission reduction, to impose quotas on energy consumption and incorporate criteria related to energy conservation and emission reduction as parts of the annual appraisal. The Company has established an energy-saving and carbon-reduction steering body to coordinate energy-saving and emission and carbon-reduction efforts, and issued the Implementation Rules for Contracted Energy Management Projects for regulated management to push ahead with energy-saving projects.

In 2019, the Company altogether consumed 60.57 million of woven bags, approximating 10,297 tonnes.

Energy use

The energy used by the Company mainly comprises natural gas, coal and electricity, among others. In 2018, the Company’s comprehensive energy consumption amounted to 4,079,107.99 tonnes of standard coal, among which natural gas consumption amounted to 2,915,461.71 10,000Nm³, accounting for 71.47% of our total energy consumption. Coal consumption aggregated 1,042,774.25 tonnes, representing 25.56% of total energy consumption. Electricity and other energies accounted for 3.20% of our total energy consumption.

Energy conservation

The Company vigorously promotes the use of advanced energy-saving technology, equipment and so on through technological upgrades. In 2019, the Company promoted and implemented 12 energy-saving technical renovation projects, and realised a technical energy saving of 47,000 tonnes of standard coal, accounting for 1.1% of the Company’s annual total energy consumption. Among these, CNOOC Fudao’s general improvement and energy-saving project for recycled water saved RMB24,800,000 in electricity, and CNOOC Huahe’s power generation project which made use of the residual pressure of recycled water saved more than RMB6 million annually in terms of efficiency increment. CNOOC Huahe’s unit comprehensive energy consumption for ammonia products decreased by 4.3% from the same period in 2018 to 1,634kgce, which achieved both goals of making it below the 1,680kgce standard for ammonia production and the 1,650kgce standard for new ammonia plants, and saved 11,772 tonnes of standard coal and 11,036 tonnes of water for the whole year. DYK Chemical pushed ahead with product structure upgrade to increase output of compound fertilisers and explore the new process of production by ore, acid type and product. Equipment for phosphoric acid production could be operated separately to produce various grades of phosphoric acid during different time periods. The buffer of sets of equipment for phosphate and compound fertiliser production was fully used to produce different grades of phosphate and compound fertiliser products.

Water resource conservation

The Company advocates water conservation and takes a proactive approach in adopting water-saving measures and implementing various technological upgrades. DYK Chemical achieved “zero discharge” of wastewater for complete recycling and reuse. The greywater reuse devices in CNOOC Fudao and CNOOC Huahe both function steadily and continuously play a role in water conservation. In 2019, the Company consumed 37,246.50 thousand tonnes of freshwater and conserved 76.5 thousand tonnes of water. The Company successfully obtained and utilized the water source, and caused no significant impact on the environment or the external world.
