Carbon dioxide of fossil fuels and deforestation have caused the atmospheric concentration of carbon dioxide to increase by about 43% since the beginning of the age of industrialization. Most carbon dioxide from human activities is released from burning coal and other fossil fuels. Other human activities, including deforestation, biomass burning, and cement production also produce carbon dioxide. Human activities emit about 29 billion tons of carbon dioxide per year, while volcanoes emit between 0.2 and 0.3 billion tons. Human activities have caused to increase above levels not seen in hundreds of thousands of years. Currently, about half of the carbon dioxide released
Carbon capture and storage development completed in 2018. The source of carbon dioxide is the nearby Changling gas field, from which natural gas with about 22.5% CO is extracted. After separation at the natural gas processing plant, the carbon dioxide is transported to Jilin via pipeline and injected for a 37% enhancement in oil recovery at the low-permeability oil field. At commercial capacity, the facility currently injects 0.6 MtCO per year, and it has injected a cumulative total of over 1.1 million tonnes over its lifetime. The Sinopec Qilu Petrochemical Corporation is a large energy and chemical company currently developing a carbon capture unit
