Sarkozy's green revolution in danger of producing nothing more than hot air

President Nicolas Sarkozy promises to add a green stripe to the French tricolour today in a speech which will place France at the cutting edge of the fight against global warming. That in any case is the theory. The contents of the President's speech will be decided this afternoon at the end of an unprecedented two-day conference and consultation exercise which is intended to shape France's approach to everything from carbon emissions to pesticides and bio-diversity.
