Computer networks, communication systems, and other IT infrastructures have caused severe environmental problems by consuming significant amounts of power, increasing greenhouse gas emissions, and lead to pollution during the production and disposal. To reduce such environmental problems and create a sustainable environment, new energy models, algorithms, methodologies, platforms, tools and systems are pressing. Thus, green computing and communications solutions should be designed with more renewable energy, higher energy efficiency, lower greenhouse gas emission, and less harmful materials.

The 2015 IEEE International Conference on Green Computing and Communications (GreenCom 2015) will be an exciting international forum for scientists, engineers, and researchers to exchange their novel works regarding advancements in the state-of-art of green computing and communications, as well as to identify the emerging research topics and open issues for further researches. The GreenCom 2015 is the next event of the successful International Conferences on Green Computing and Communications, previously held as GreenCom 2014 (Taipei), GreenCom 2013 (Beijing, China), GreenCom 2012 (Besançon, France, November, 2012), GreenCom 2011 (Chengdu, China, April, 2011), GreenCom 2010 (Hangzhou, China, December, 2010), PerGrid-09 (Vancouver, Canada, August 2009), PerGrid-08 (Sao Paulo, Brazil, July, 2008), WESAPEC-07 (Jeju Island, Korea, October, 2007), Multisec-06 (San Diego, USA, December, 2006) and Multisec-05 (Irvine, USA, December, 2005).
