A new European push for a successor international treaty to the Kyoto protocol was heralded on Monday with the publication in Britain of a government report calling for rapid action to tackle global warming while the economic cost of doing so was still manageable.
The report for the first time attempts to quantify the economic cost of taking action now – which it said would be just 1 per cent of world economic output by 2050 – against the cost of a failure to act, which it said would knock between 5 and 20 per cent off world consumption.
