The world would require measures more far reaching than the Kyoto agreement to address climate change, federal Environment Minister Ian Campbell said today.
Parties to the Kyoto agreement to reduce greenhouse gas emissions are meeting in Buenos Aires for the last time before it comes into effect in 2005.

Australia has refused to ratify the deal, but Senator Campbell said the world could do much more to patch up the changing climate.
"Kyoto was a start, it's got the world focused on it, but we are going to have to do a lot better if we are to address climate change," Senator Campbell told ABC Radio's AM program.
"What we do need to do at the conference in Argentina is work out how is the world going to address the beyond Kyoto task, and Australia will be deeply engaged in that."
Even though the government had not signed the treaty, Senator Campbell said Australia was on track to meet the greenhouse gas reductions targeted by the Kyoto protocol.
Opposition environment spokesman Anthony Albanese said if the government was on track to meet the targets, it had no reason not to sign the treaty.
"They say they're meeting the targets but in effect they're locking themselves out of the economic potential (of the Kyoto agreement)," Mr Albanese told AM.
"It's all about politics, and not good economic policy and good environmental policy."
