Environmental Protection

To develop a low-carbon and renewable economy, CNOOC makes great efforts to become a resource-efficient and environment-friendly company. The company implements preventive and whole-process control in environment protection in project construction and operation, which effectively reduces influences to the environmental and realizes sustainable development of the company.

Responding to Climate Change

CNOOC actively promotes green industrial transformation by upgrading technologies, promoting carbon emission trading, researching on framework of greenhouse gas emission standards, carbon inventory and the capturing, storage and utilization technologies of carbon dioxide.

Following the clean energy transformation in China, the company highlights the development of natural gas segment, offshore gas fields, LNG receiving terminals and unconventional gas, including CBM and shale gas.

Energy Conservation and Emission Reduction

CNOOC always deems energy conservation and emission reduction as an important way to transform development mode and improve core competitiveness. The company strictly complies with national energy conservation laws and regulations and conducts energy saving and emission reduction throughout production, distribution and consumption links with a management information system. It also invests funds into technological upgrading to achieve the target.

The recording, counting, supervision and alarming of industrial wastewater, waste gas and residues are implemented through the information platform, which serves as a flat and fine management mode for the company.

CNOOC promotes emission reduction programs by reducing scale and upgrading fuels, including transformation of smoke desulphurization and odor removal in refineries. In 2015, its emissions of SO2, NOx, COD and Ammonia Nitrogen were 8,844 tons, 15,187 tons, 1,723 tons and 149 tons respectively, with a year-on-year decrease of 29%, 16%, 2% and 67%.

To improve the utilization rate of water resource, CNOOC places emphasis on technological progress and innovations, intensifies supervision, and strengthens wastewater treatment and recycling. In 2015, CNOOC saved 1.27 million tons of water.

In 2015, CNOOC consumed 1.947 million tons of standard coal, 4.638475 billion kWh of electricity, 306,698.7 tons of crude oil, 327,686.1 tons of diesel oil, 6.824505 billion cubic meters of natural gas, 19,896 tons of fuel oil, 3,979.5 tons of gasoline and 34.6985199 trillion KJ of heating power. Its energy consumption per RMB 10,000 turnover is 0.2731 tons of standard coal equivalents, decreasing by 3.9% year on year, which surpassed the planned annual target. 308,000 tons of standard coal equivalents were saved, which was179.5% of the target in the annual plan. In terms of its major products, including oil and gas production, crude oil processing, soda ash, synthetic ammonia and power generation, the unit energy consumption continued to decline, and that of some products were at an internationally leading level.

Ecological Protection

CNOOC sticks to ecological protection during all phases of projects. The company strives to protect the ecological diversity of the operating sites and the neighborhoods by evaluating environmental risks, identifying environmentally sensitive targets and avoiding risks in advance. The measures help to realize harmonious relations between economic development and ecological environment.

NOOC Marine Environmental and Ecological Protection Foundation continues to support studies and programs of biodiversity and promote ecological recovery in operation areas. Meanwhile, CNOOC actively involves in environmental initiatives and makes efforts to create better ecological conditions in China.

CNOOC carries on release activity in China seas, releasing 980 million rare and protected maritime species, including penaeus penicillatus, pseudosciaena crocea, sparus latus and anguilla japonica. Among them, 110,000 were tachypleus tridentatus which are one of the most ancient species on the Earth and are known as living fossils. The activity has effectively promoted the sustainable development of fishery and increased fisherman’s revenue, promoting the development of local economies.

CNOOC actively conducts transplantation of mangrove forest and coral reef. In 2015, the company grew 520,000 mangrove plants in the coastal belt of Kaozhou Bay of Huidong County in an area of 310 mu. Mangrove forest plays an important role in purifying maritime water quality, protecting animal habitats and bio-diversity, and improving local natural environment.

In the Daya Bay, the company’s young volunteers worked with diving volunteers from the Pearl River Delta region. They fixed 200 coral seedlings at five iron coral shelves, and divers laid the shelves on the soft sandy land of the seabed, which provides a diverse ecological space for maritime animals to live and breed.

In the Yellow Sea and the Bohai Sea, CNOOC conducts survey on the population quantity and migratory distribution of neomeris phocaenoides and its protection. The neomeris phocaenoides are under second-class state protection and listed into the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Under the pressure of deteriorated maritime ecological environment and overfishing, their living conditions have become increasingly severe. CNOOC sets up a five-year “Population Quantity, Migratory Distribution and Protection of Neomeris Phocaenoides” project.

By surveying, collecting and preserving the mudflat shellfish species in coastal areas of the Bohai Sea, the company conducts qualitative and quantitative analysis and evaluation of resource distribution of mudflat shellfishes in the area and establishes a resource directory of mudflat shellfish species in coastal areas of the Bohai Sea at Shandong Province, which provides data for reasonable exploitation and utilization of mudflat shellfish species in the Yellow River Delta zone.

In the Bohai Sea, an environmentally-sensitive resource identification system has been put into operation. The system can realize identification, quantitative analysis and assessments of environmentally-sensitive resources in the planning of offshore oil and gas field.

In Southeast Asia, CNOOC digs “Biopori” to capture water and prevent floods on the World Environment Day. Husky—CNOOC Madura LLC (HCML), a company co-established by CNOOC Southeast Asia Limited and Husky Energy, responded to the call of United Nations Environment Programme and organized 120 Chinese and Indonesian employees to dig “Biopori”. The measure enhances the capacity of the ground to absorb and retain rainwater and minimizes the influence of floods on downstream low-lying land.

The Long Lake Oil Sands Project constructs corridors for the animal migration. Nexen selects four places in the area and buries the early ground oil pipelines to create migration corridors for animals. In 2015, the corridors were in a good condition, deer, wolves, bears, lynx and other animals were often seen passing through the corridors.

In addition, Nexen funds Nature Conservancy Canada (NCC) all year round to conduct biodiversity conservation and science activities, participates in the volunteer activities of NCC and promotes wildlife protection to the public.
