The CRC carbon tax, which the IT industry fears will increase data centre costs, is to be simplified once again, according to proposals published yesterday which are open to consultation till June. The CRC was put under notice by the Chancellor in his budget speech as too expensive. The Department’s proposals hope to save the tax by cutting the administrative cost by around two-thirds. The CRC imposes a tax on energy use, and rates organisations in a league table of efficiency, as a way to push companies to reduce their greenhouse emissions. Criticised for its complexity, simplification of the CRC has been on the cards for some time and last week’s budget started speculation the tax might be abolished.
