CNPC unveiled its first three voluntary biosphere reserves (based on the same standards as the Other Effective Area-based Conservation Measures, or OECMs) in the Guowu Lake and Tiger Mountain areas at Daqing Oilfield, and the A'ershan Donghu Wetland at Huabei Oilfield, respectively.

Always attaching great importance to biodiversity conservation, CNPC has incorporated biodiversity conservation into the management system. We have formulated and issued the Ecological Protection Action Plan, the 14th Five-Year Plan for Green Development, the Ecological Ban and other regulations. Adhering to our principle of promoting the integrated protection and systematic management of mountains, rivers, forests, farmlands, lakes, grasslands and deserts, we have adopted natural restoration measures and environmentally-friendly restoration processes, carried out ecological and environmental protection in the Yangtze River, Yellow River and other key river basins, built biodiversity conservation areas and green mines, and implemented a variety of biodiversity conservation practices.

Covering an area of 1.98 million square meters and 2.17 million square meters respectively, the two reserves (Guowu Lake and Tiger Mountain) have good conditions for biodiversity conservation, nurturing a variety of national protected animals and plants, as well as dozens of provincial protected bird species. The A'ershan Donghu Wetland at Huabei Oilfield, covering an area of about 15,000 square meters, is a habitat and breeding place for various waterfowls and is of great ecological value.

According to CNPC's 14th Five-Year Plan for Green Development, we will build 10 voluntary biosphere reserves by 2025, continuously improve the stability and sustainability of the structure and function of these ecosystems, and make our due contribution to the development of ecological civilization.
