From Derek Shotton
Power producers should pay for cleaning up their emissions, David R. Allen suggests (16 February, p 33). If all countries agree, that’s fine: problem solved. If not, any country that continued to pollute would gain a huge financial advantage over its competitors.
Certainly, the only way to stop the massive increase in atmospheric carbon dioxide is to impose a charge, either on emissions or fuel, and to allow competition to provide the cheapest alternative. This would work only with international agreement through the United Nations. The current subsidising of certain “green” measures does little if anything to reduce global emissions, and disadvantages the nations that do it.
