Microsoft has claimed that the use of cloud computing technology can reduce per user carbon emissions by 30 per cent.
The study, which was carried out by Microsoft, Accenture and WSP Environment & Energy, contradicts claims made by Greenpeace and a group of Australian researchers who had said that cloud computing does more harm to the environment.
In the study, Accenture and WSP studied three of Microsoft's most widely deployed cloud services related to e-mail, content sharing and customer relationship management in cloud-based data centres, IDG News Service reports.
According to Microsoft, cloud computing services reduced carbon emissions by 30 per cent in large organisations, while small organisations were found to cut up to 90 per cent.
The study conducted by Accenture took into account the carbon footprints of server, networking and storage infrastructures deployed in three different types of organisation sizes - 100 users, 1,000 users and 10,000 users.
James Harris, Accenture's director of cloud services, said in a statement to IDG News Service: “The study's findings confirm what many organisations have already discovered: Cloud computing is more economical and IT resources are used more efficiently when business applications run in a shared environment.”
