Carbon footprint man-made infrastructures resulted in a net loss to the atmosphere, -0.6 Mg C ha y. Carbon dioxide emissions into the atmosphere, and the emissions of other GHGs, are often associated with the burning of fossil fuels, like natural gas, crude oil and coal. While this is harmful to the environment, carbon offsets can be purchased in an attempt to make up for these harmful effects. The Kyoto Protocol defines legally binding targets and timetables for cutting the GHG emissions of industrialized countries that ratified the Kyoto Protocol. Accordingly, from an economic or market perspective, one has to distinguish between a
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
