The company's primary environmental impact is its energy use. The carbon footprint of a mobile phone is made up of the energy required to manufacture and power the phone as well as the energy needed to run the base stations that transmit radio waves through a network of fixed antennas. China Mobile is working to improve the efficiency of its base stations; upgrades include intelligent ventilation and heat exchange systems that allow for reduced air conditioning and a centralized monitoring system that can remotely control cooling equipment. The company has also implemented an energy conservation rating for its telecommunication and auxiliary equipment and it increases energy efficiency by upgrading this equipment biannually. Additionally, China Mobile utilizes renewable energy at a small percentage of its base stations.
In 2005, the company established a take-back program for all mobile phones, batteries, and accessories; recycling bins are available at its outlets and partner facilities. Despite the significant energy efficiency efforts of China Mobile, as a result of China's fuel mix, which is heavily dependent on coal, the company's carbon dioxide emissions are relatively high, especially when compared with its U.S. and European competitors. As a result, Portfolio 21 has asked the company to expand its renewable energy commitments.
