China: China National Building Material Group Corp (CNBM), China's largest building materials manufacturer, invested about USD131m in energy saving and emission reductions in 2010, according to the company's 2010 corporate social responsibility report. The construction industry has long been known for its heavy pollution and high energy use.

The Beijing-based, state-owned company gave top priority to fulfilling its corporate social responsibility (CSR) in terms of energy saving. "The company has dedicated itself to energy conservation by investing in clean technology," said Song Zhiping, chairman of CNBM. According to Liu Baoying, vice-president of CNBM, the cement sector is a major contributor to the company's energy consumption, accounting for more than 90% of the total.

"The company's energy consumption in the cement sector was down by 23% during the period of the country's 11th Five-Year Plan (2006-2010), mainly because of our efforts to eliminate poor production methods and upgrade technology," said Liu. CNBM has disposed of 51 energy-inefficient cement operations with a total capacity of 6.8Mt/yr over the past five years, according to its CSR report.

The country as a whole has also attached great importance to decreasing its carbon footprint with the government targeting reductions in CO₂ emissions for every unit of gross domestic product by between 40-45% by 2020 compared with 2005 levels. In addition, CNBM has made substantial efforts in developing new building materials in a bid to reduce energy consumption.

Beijing New Building Material (Group) Co Ltd (BNBM), a subsidiary of CNBM, mainly focused on manufacturing houses made of new building materials that can save electricity, water and materials during construction. They can also reduce by 60-90% the energy used when the buildings are functional, said Cui Lijun, general manager of BNBM.
