Finance (No. 3) Bill

Is it the Government's policy, then, to use fiscal measures to reduce carbon emissions? Is that what brought about the carbon variation of 1.4 megatonnes—is that what the hon. Lady said? [Interruption.] It is 0.4 megatonnes; I am grateful to stand corrected. Has the reduction that she mentioned come about as a result of the Government's proposed fiscal changes, or as a result of the economic downturn that is a result of their policies? There is an important difference. One would expect the fall in economic activity that we have seen as a result of the Budget—the Office for Budget Responsibility has revised down its forecast for growth as a result of the Government's fiscal measures so far—to lead to a decline in carbon emissions from both road transport and other sources. I am not clear from what the hon. Lady has read out whether the reduction in carbon emissions will be a result of the fiscal measure or of a reduction in demand because of a contraction of the economy.
