According to Fourth Assessment Report of Intergovernmental Panel on Climate Change, released in 2007, a goal of limiting global average temperature rise to less than two degrees Celsius compared to pre-industrial levels will require a 50 to 85 percent global reduction of greenhouse gas emissions by 2050. In concert with United Nations Climate Change Conference 2009 in Copenhagen, Microsoft revealed its own three pillars strategy designed to help reach climate and environmental goals. Of course, for Microsoft, it’s first and foremost about software. Microsoft argued that moves such as migrating to Windows 7 as well as swapping physical servers for virtualized environments’re both measures that’ll drive environmental sustainability. “Microsoft’s also focusing on accelerating breakthrough solutions to environmental challenges. These breakthroughs’ll require collaboration amongst private sector, government and non-government organizations. To this end, we’re partnering with leading scientists and academia to leverage technologies that help us better understand our planet and impact we’ve on it,” Microsoft.
