This document discusses potential leadership roles for the Communications Research Centre (CRC) in developing a national Green IT strategy in Canada. It recommends that CRC establish a pilot program to host government applications on its GreenStar Network and offer virtualization services to departments. This would allow CRC to assess the actual energy costs of computing, establish an incentive mechanism where departments are rewarded for reducing physical infrastructure, and negotiate with Public Works to receive credits for measurable energy reductions achieved through Green IT solutions. The document also provides background on climate change impacts, trends in climate policy and regulations, case studies of Green IT programs at other organizations, and other potential roles for CRC in certifying the carbon impact of IT and demonstrating Green IT solutions to small and medium enterprises.
