Microsoft Introducing Corporate Carbon Tax

Microsoft has announced that they will introduce an internal "carbon fee" on all business divisions, with the aim to be carbon neutral from 1 July 2013 ("Making Carbon Neutrality Everyone’s Responsibility at Microsoft, 8 May 2012 12:01 am). Microsoft's approach is very similar to the carbon pricing scheme which the Australian Government is introducing.

Microsoft also have:
