This article explains why. Basically to raise significant sums of money the level needs to set high, but if it is and it lowers carbon emissions then it will raise less tax and so need to rise......etc. A bit like filling a bucket which is being shot at causing a constant increase in holes.  Of course, raising tax from industry will cause prices to raise, reducing competitiveness and hence sales, resulting in job losses and eventually closure of businesses.
