NO new taxes _ that's what Tony Abbott will go to the next election promising.

The new Liberal leader committed to cutting carbon emissions by at least 5 per cent, but ruled out any emissions trading scheme or carbon tax to achieve the target, The Herald Sun reported.

He also said he would consider nuclear power as a means of reducing emissions.

The Government's emissions trading scheme was blocked for a second time in the Senate, despite a stand by two Liberal senators - Judith Troeth and Susan Boyce - to cross the floor.

But as soon as the Government got its double dissolution election trigger, the Government blinked.

Acting PM Julia Gillard said it would be reintroduced in Parliament next year giving "calmer heads" in the Liberal Party time to change their minds.

"We are doing this to give the Liberal Party one chance to work through and deal with this legislation in the national interest," Ms Gillard said.

Senior Labor figures insist the Government will take its time with Mr Abbott, whose shock election as Liberal leader has radically changed the political landscape.

ALP strategists believe that Mr Abbott will get a decent honeymoon, but voters will eventually turn on him.

The Opposition Leader yesterday said the Coalition remained committed to a 5 per cent cut in carbon emissions, and up to 25 per cent if other nations acted too.

He said he was "not a theological opponent of nuclear power".

But there would be no ETS under any circumstances if he won the next election.

"Whether it's a stealth tax (like) the emissions trading scheme, whether it's an upfront and straight forward tax like a carbon tax, there will not be any new taxes as part of the Coalition's policies," he said.

The ETS Bill will be reintroduced in February with amendments negotiated with Malcolm Turnbull, including $7 billion more for industry and an exemption for agriculture.
