China has revised its 2008 unit GDP energy consumption cut to 5.2 percent from the previous 4.59 percent, the National Bureau of Statistics (NBS) said Friday.

The energy cut increased 12.45 percent from 2005.

National energy consumption totaled an equivalent of 2.91 billion tonnes of standard coal, up 2.12 percent from the previous data. Figures for 2005 to 2007 were also revised.

The new statistics showed that output of the country's primary energy equaled 2.65 billion tonnes of standard coal in 2008, which included 2.8 billion tonnes of raw coal, 195 million tonnes of natural crude oil and 80.3 billion cubic meters of natural gas, according to NBS director Ma Jiantang.

The revision came after China finished its second national economic census to gather basic information of all industrial and service-sector entities active in 2008.

The census is conducted every five years and the latest one started in October last year, aiming to help form the basis of the social and economic development blueprint for the 12th Five-Year Plan (2011-2015).
