Australia's government has agreed to exclude agriculture from its emissions trading scheme in a major concession to the opposition to try to get carbon trading laws through parliament, a minister said on Sunday. The scheme has been delayed in the Senate and the move triggered speculation of an impending deal a day before parliament reopens and in the run-up to major UN climate talks in Copenhagen next month. Prime Minister Kevin Rudd's Labor Party does not have a majority in the Senate and needs the votes of seven other lawmakers to pass the carbon trade bills. A vote is expected during the week of Nov. 23. His government leads opinion polls, but ministers are seeking passage of the legislation to guard against an early election. Both sides on Sunday said talks were proceeding. Climate Change Minister Penny Wong announced the concession and called for quick approval by parliament. “We've got the opportunity to pass for the first time legislation that actually reduces Australia's contribution to climate change,” Wong told the Australian Broadcasting Corporation. “That is why we will continue to move forward in those negotiations because this is in Australia's national interest. We need to get this reform through.” The government had planned to include agriculture in the scheme from 2015. Under the revision, agriculture will be excluded, but farmers will still be able to claim carbon credits. Opposition leader Malcolm Turnbull welcomed the concession, which will please rural voters, a key support base for his conservatives. “It's certainly a key part of our set of amendments that we've put to the government,” Turnbull told Channel Nine television. The carbon-trade laws were defeated a first time in August in the Senate, but Rudd wants the plan passed before the Copenhagen talks that aim to yield a broader agreement on how to expand the global fight against climate change. Rudd has been given a key role by Denmark to try to guide the talks and passing the carbon trade laws this month would boost his climate credentials, analysts say. A new vote is expected in the lower house in coming days, after which the bill goes to the Senate. A second defeat in the upper house would give the prime minister the right to call an early election, although he has discounted that option. Passing the laws would give industry, such as power generators, more certainly on investment plans and financing. The opposition, however, is deeply split over emissions trading. Many conservatives deny that there is even proof that human activity is causing climate change. The opposition has also demanded more compensation for emissions-intensive export industries, such as aluminium smelting, cement making and coal mining. Under the proposed scheme, trading at a fixed price of A$10 a tonne of carbon dioxide would start in July 2011, requiring businesses to secure a permit for every tonne of CO2 they emit, providing an incentive to curb carbon pollution.
