Carbon tax 'may not reduce CO2'

When the government changed the terms of a new tax on the carbon emissions of
large companies in last year's Spending Review, it was accused of hitting
firms with a "green stealth tax".

Money raised through the Carbon Reduction Commitment (CRC) will now go to the
government, rather than to those firms who cut their bills the most, as had
been originally planned.

The business group, the CBI, is calling on the government to turn the tax back
into an incentive-based scheme or scrap it altogether.
