Britain has become the first country in the world to make a legally-binding commitment to cut its greenhouse gas emissions by 80per cent by the middle of the century.

"The hard part is meeting it – and meeting the milestones that will show we\’re on track.
Quite. We\’ll do something, we know not what but they will be the wonder of mankind.
