http://news.bbc.co.uk/1/hi/uk_politics/4412228.stm Which emits more harmful pollution? A petrol pump or a car? Answers on a postcard to ; 'We're not addressing the issue but we'll say any old bollox so as not to offend the oil companies and motor manufacturers , c/o 10 Backhand Street , London. SW1.'
