change adviser, “and realised that there would be new products and new rules. It was in our interest to be part of the discussion, in a constructive way.�? Companies that were hostile to green regulation were not going to be invited to the table, so those that wanted to be involved had to acquire some green credentials and flaunt them. There were indeed new rules, in the fo fuel dispenser rm of Europe s Emissions-Trading Scheme, and industry did well to be involved in the discussions. Economists were arguing for a carbon tax. Industry wanted emissions limited by quantity, rather than by price. “We didn t want a tax,�?says a BP executive. “We didn t want a system in which the level was set by the budget deficit rather than by the cost of carbon.�?Industry won. Economists argued that the most efficient way to run the system would be to auction permits to emit CO2. Industry wanted permits handed out free. Again, industry won, and has profited nicely from the scheme. The fact that so many European polluters have done so well out of the ETS is one reason why some airline bosses, including Sir Richard Branson of Virgin and Sir Rod Eddington, the former chief of British Airways, are arguing for a trading scheme for their industry; and why American companies are fuel dispenser now less hostile to the idea than they were before the ETS started up. But there is more than just lobbying going on. Climate-change regulation, and the prospect of more of it, is changing the way business thinks about carbon and leading it to invest in new areas. The Shell greenhouse project is an example of how regulation drives investment. Thanks to the ETS, says Mr Hone, “CO2 gets attention from people like oil-refinery managers these days. There s a clear price signal. Projects to control emissions are worth investing in.�? And there is a bit more investment in cleaner technology and renewable energy than there used to be. The wind business, for instance, is booming, thanks to subsidies in Europe and America. “We ve had a wonde fuel dispenser
