The most important talks on climate change since the Kyoto Protocol are reaching a climax, but prospects for a unanimous agreement are grim. The discussions in Montreal are aimed at striking a new deal on reducing greenhouses gases.Canadian Prime Minister Paul Martin said: “We’re in this together. The developed world cannot walk away from its responsibility. It’s as clear an simple as that.” But the US, which opted out of Kyoto along with Australia, insists focusing on curbing emissions is not the right approach. US delegate Paula Dobriansky said: “It is our belief that progress cannot be made through these formalised discussions.” The Kyoto Protocol was intended to reduce emissions by five percent of 1990 levels. It runs out in 2012. The Montreal conference ends tomorrow.
