Abstract: In China, cement manufacturing has contributed 1788.78 million metric tons of CO2 (carbon equivalent) into atmosphere in the past 35 years (1969-2003). Its driving forces were analysed by a stochastic regression model (STIRPAT), which showed that population was a key driving force and its pressure was higher than the global average level. On the other hand, economic growth had less impact, but a doubling in economic growth might result in nearly doubling in CO2 emissions. In three STIRPAT models, evidence for the existence of the Environmental Kuznets Curve (EKC) was found, with a turning point well beyond the present value.

Keywords: carbon emissions; carbon dioxide; cement industry; environmental Kuznets curve; EKC; STIRPAT; China; environmental pollution; stochastic regression modelling; air pollution.
