McCartney on meat-free Mondays

Sir Paul McCartney has appealed for "people power" to make the difference in the fight against global warming.

In an article published today he says cutting out meat consumption one day a week can have a major impact on reducing CO2 emissions.

Sir Paul, who takes his "Meat-free Monday" campaign to Brussels this week, uses an interview in Parliament Magazine to insist that halving UK household meat consumption would do more to reduce emissions than halving the use of private transport.

The estimate, by Compassion in World Farming, is central to a crusade Sir Paul began last June and will continue on Thursday at a European Parliament conference also being attended by UN climate change chief Dr Rajendra Pachauri.
