Cloud computing is positioning itself as a new emerging platform for delivering information infrastructures and resources as IT services. Customers (enterprises or individuals) can then provision and deploy these services in a pay-as-you-go fashion and in a convenient way while saving huge capital investment in their own IT infrastructures. It has evoked a high degree of interest internationally with many challenges such as security and privacy remaining open. Green computing, in general, aims to enable computing and IT infrastructures to be energy efficient and environmentally friendly. With dramatically increasing demand on computing and storage systems, IT infrastructures have been scaled tremendously which results in huge amount of energy consumption, heat dissemination, greenhouse emission and even part of climate change. As such, green computing has come to the picture seeking solutions for computing and IT infrastructures to be energy efficient and environmentally friendly.

While customers can enjoy green atmosphere as well as cost saving and convenience because cloud computing accommodates their IT infrastructures in the cloud, how to green the cloud becomes increasingly challenging and extremely important in terms of global energy efficiency and environmental sustainability.

CGC (Cloud and Green Computing) is created to provide a prime international forum for both researchers, industry practitioners and environment experts to exchange the latest fundamental advances in the state of the art and practice of Cloud computing and Green computing as well as joint-venture and synergic research and development across both areas.

Xiangtan is a city in China's Hunan Province that is located on the lower reaches of Xiang river, which is very close to Changsha (30km), Hengshan (60km) and Zhangjiajie (National Forest Park). It is the hometowns of several founding leaders of the Chinese Communist Party, including Chairman Zedong Mao, Shaoqi Liu, and Dehuai Peng, as well as the hometowns of Qing Dynasty painter Baishi Qi and military general Guofan Zeng.

CGC2012 is in technical co-sponsorship with IEEE and IEEE Computer Society Technical Committee on Scalable Computing.
