A preliminary estimate by The Netherlands Environmental Assessment Agency (Milieu- en Natuurplanbureau, MNP) concludes that China’s CO2 emissions in 2006 surpassed those of the USA by 8%, rising to 6,200 megatonnes. This includes CO2 emissions from industrial processes, notably cement production. With this, China tops the list of CO2 emitting countries for the first time.
In 2005, China’s CO2 emissions were 2% below those of the US. MNP based its estimate on recently published BP energy data and cement production data.
Of all industrial processes, cement clinker production is the largest source of CO2. It contributes around 4% to the total of CO2 emissions from fuel use and industrial activities, globally. China has a large share in global cement production (about 44% in 2006), and cement production’s domestic share of CO2 emissions in China is almost 9% (550 megatonnes out of a total of the total 6,200 megatonnes).
