The SASAC also ordered firms to step up efforts to develop and apply energy saving techniques and equipment and to abandon outdated production facilities.

The 30 most energy-consuming firms are ordered to report the data on the energy consumption and pollutant emissions quarterly, and 66 that consume less energy half-yearly and the other 58 yearly.

"Many SOEs have made progress in eliminating less energy efficient and highly polluting techniques and equipments in the past couple of years, but there are still some that are still using them," Huang said.

The SASAC would also promote good energy saving and pollution reduction practices and report company officials who cause energy waste, serious environmental degradation or make false reports, said Huang.
