Energy Saving & Emission Reduction

20140513143327115 Being an energy company, CNPC has established an effective mechanism to include energy conservation and emission reduction work into its enterprise performance appraisal system, and raise the energy conservation and emission reduction awareness of all staff.

Energy Saving

We intensify our efforts in energy conservation and energy efficiency enhancement, reduce the environmental pressures arising from energy consumption, and endeavor to build ourselves as a resource-saving and environmentally friendly enterprise. We strengthen energy source management, and carry out energy-saving assessment at the stage of the feasibility study for newly-developed, revamped and extended projects. We reinforce energy use management in the production process, conduct monitoring and evaluation of energy and water-intensive devices and equipment, and substitute oil with alternatives such as electricity, gas and solar energy.

In 2015, we implemented 54 energy-saving technology renovation projects, covering the mechanical oil extraction system, ethylene cracking furnace, and hydrogen system. New technologies and equipment for a high-efficiency combustor and a new type of heating furnace were developed, and the performance evaluation and operation management of heating furnaces were strengthened. We continued efforts on optimizing the energy system at our refineries, and conducted model development and optimized analysis in our key subsidiaries, developing 148 optimization programs. Additionally, our energy-saving standard system was improved as six national or industrial standards and five corporate standards were formulated. Throughout the year,we reduced energy consumption by 1.16 million tons of standard coal and water consumption by 20.61 million cubic meters.

In 2016, we continued to strengthen the management of energy use in production and operation and issued the Opinion on Promoting Energy Management. In 2017, we carried out demonstration projects of energy management in Changqing Oilfield and Jinzhou Petrochemical, and organized major energy consuming subsidiaries to formulate and implement action plans for energy management to increase energy efficiency and lower energy consumption. Throughout the year, we reduced energy consumption by 880,000 tons of standard coal.

Sustainable Application of Energy

We attach great importance to the protection and rational utilization of resources. We strengthen the protection of water, conservation of freshwater, and rational use of land, and strive to improve energy and material utilization efficiency to minimize resource consumption.

Water Resources

We endeavor to improve water utilization efficiency and realize sustainable water utilization throughout various links in our production and operation activities. Through strengthening water conservation management, water-saving technological transformation and wastewater treatment and recycling technology and other measures, we worked to reduce the use of fresh water. In 2017, we saved 12.41 million cubic meters of water.


Land Resources

To protect land resources, we make careful and intensive use of land during production, strictly control land use growth, make good use of land through various ways, actively reclaim land, and carry out environmental treatment and recovery in mining areas. We optimize the project plane scheme design to reduce land occupation during the preparation period for oil & gas exploration and development, pipeline construction, and refining & chemical projects in accordance with the requirements of economical and intensive land use. For newly added service stations, we rationalize the layout of stations to maximize land utilization. For projects that occupy farm or forest land, and projects that affect ground attachments during pipeline construction, we actively adopt advanced technologies for land reclamation and provided reasonable compensation to relevant parties.

In 2017, 15,000 hectares of land were reclaimed  and 1,180 hectares of land, about 7,867 square kilometers were saved by CNPC.

Emission Reduction

We strictly control pollutant emissions, strengthen waste management, and fully implement the national requirements on pollutant emissions. By utilizing advanced applicable technology, we do our best to minimize adverse impacts on ecological environment.

In 2015, the emission intensity per unit of crude oil production of four major pollutants measured by chemical oxygen demand, ammonia nitrogen, sulfur dioxide and NOx decreased by 31.5%, 23.1%, 33.6% and 28.3% respectively, compared with 2010; the emission intensity per unit of crude oil processing decreased by 27.8%, 28.8%, 54.8% and 32.0% respectively, compared with 2010.

In 2016, we implemented 58 projects to reduce emissions, including 49 on waste gas emission reduction, and 9 on waste water discharge reduction. Emissions of sulfur dioxide, ammonia nitrogen, COD and nitrogen oxides dropped continuously.

In 2017, we formulated the Plan on the Upgrading of Pollutant Discharge Compliance, and proposed 12 major directions for the management of environmental protection, covering all elements of water, air, noise, and solid waste, as well as the whole process of exploration and production, refining and petrochemical, natural gas and pipeline, and engineering technology.
