The global output on green computing consisted of 7335 publications during 10 years from 2009 to 2018, registering fastest 108.06% growth and low citation impact of 4.10 citations per paper. The paper presents a profile of top 10 most productive countries, 15 most productive organizations and 15 most productive authors on a series of indicators, including publications output, citations, citation impact, h-index, international collaborative papers and relative citation index in green computing research. The paper also identifies top 15 most productive journals and presents the bibliographical characteristics of top 27 highly cited papers in this area. Keywords: Global green computing research, Scientometrics, Green computing, Citation impact, Relative citation index 1 Introduction Green computing or IT is a synonym to environmentally sound Information Technology (Murugesan, 2008). It includes multiple aspects like environmental sustainability, energy efficiency economics, cost of disposal/recycling etc. When computing originated, some of the basic inputs like power, energy and other resources were considered infinite. However, with the issues of sustainability and climate change in the recent past, the effective usage of computers with limited resources is the need of the hour. Particularly, the concern of carbon emissions from the data servers is being raised worldwide as it is proportional to the energy usage (Weiss, 2007).
