Carbon emissions trading is a great idea waiting to happen, according to Charles Sturt University’s environment economist Mark Morrison. Dr Morrison says he agrees with Prime Minister John Howard, who said at the APEC summit late last week that any carbon trading system would have to be global to suceed. “The global effort is going to be ineffective unless everyone is going to involved,” said Dr Morrison. “Very few countries are meeting their commitments under the Kyoto Protocol. Australia is going to be one of the most severely affected countries. The ability of agricultural land in Australia to produce the way it has historically is very unlikely, if you believe the global warming forecasts and I do.”
