Climate Change Bill [Lords]

I shall not speculate on the extraneous matters that the hon. Gentleman has raised. The central point of what Lord Turner actually said was that policies are needed to constrain aviation and shipping emissions, but—despite these—it is unlikely that emissions in these sectors will be reduced by 80 per cent. in 2050. The consequence is that more effort is likely to be required from those sectors covered by the Bill. Government amendments Nos. 42, 43 and 50 are consequential to Government new clause 15, and ensure that appropriate references are made throughout the Bill to the proposed new clause. Amendment No. 69 and new clause 14 would both require the Government to publish regular projections for emissions from international aviation and shipping. We already publish projections of future CO2 emissions for international flights from UK airports and intend to continue to do so. The last reports were published in 2003, 2004 and 2007. I am happy to commit the Government to publish at least one forecast of international aviation emissions for each budgetary period sufficient to inform decisions on setting carbon budgets. Publishing projections of aviation emissions any more frequently would not deliver any benefits, as the long term drivers of the forecasts do not change significantly on an annual basis.
