Climate Change Bill [Lords]

The right hon. Gentleman is correct. We want to remain in the forefront and I am sure he will keep us up to the mark. Finally, and especially if we are acting alone, there is the risk of perverse impacts, such as planes and ships filling up elsewhere and coming to the UK with a heavier fuel load, of air traffic simply diverting from Heathrow to Amsterdam or Paris, or of some ships with UK-bound cargo diverting to a continental port from where the cargo is delivered to the UK by another ship or another mode of transport. All those scenarios could increase emissions, rather than reduce them.
