Microsoft is to set an internal carbon price to help drive greener business decisions across its sprawling global operations, in a pioneering policy yet to be adopted by many companies of its size.
The software group, which operates in more than 100 nations, is also looking at buying wind farms or other clean power sources as part of a commitment to become carbon neutral in the coming financial year.
The new undertaking, to be unveiled on Tuesday, will include an unusual “carbon fee chargeback” system that will mean business units responsible for incurring emissions from data centres, air travel, offices and software laboratories will be charged an internal fee according to emission levels.
