Heads of some of Britain's biggest companies are meeting Tony Blair today to demand tougher targets for cutting greenhouse gas emissions. They will say that stronger government action would encourage industry to develop the technology needed to tackle climate change...The Confederation of British Industry has previously expressed concern that UK businesses might be disadvantaged by being given tougher targets than competitors overseas. But today's meeting involves the biggest companies, including Shell, Vodafone, Tesco and Standard Chartered Bank, which are in a better position than smaller firms to adapt to the demands of emissions targets..."They are saying that strengthening targets is good for business, not bad..." [said Miliband, the environment secretary].
