CNPC ramps up efforts with pledge to cut emissions

China National Petroleum Corp, the nation's largest oil and gas producer, has pledged to cut its carbon dioxide emissions by 2020 by 25 percent compared with 2015 to further increase its clean energy capacity.

It has also vowed to increase its share of natural gas production capacity to 55 percent of the company's total energy production capacity in the country, through increasing its output of natural gas, coal bed gas and research and development into combustible ice.

As a major natural gas supplier in the country, the company saw its domestic natural gas sales exceed 151.8 billion cubic meters in 2017, which has helped meet the nation's growing demand for natural gas, under a policy to replace coal to combat air pollution.
