Transport (Greater Manchester)

I congratulate the right hon. Gentleman on his far-sightedness and on not being seduced by the short-term political opportunism of his Front-Bench team. He rightly refers to climate change; indeed, my statement referred to the environment. The only CO2 emission calculations that I am aware of were those produced by the Greater Manchester authorities, which estimated that about 6 per cent. of all CO2 emissions could be saved by the scheme.
