Prime Minister Tony Abbott is facing a push from inside the Liberal Party to prevent Australia signing up to any binding emissions reduction targets at the upcoming Paris climate talks.

A cabal of regional and rural Liberal members, centred in Western Australia and supported by a number of conservative MPs, will force a vote at Saturday's federal council meeting in Melbourne on whether Parliament should "examine the evidence" around climate change before agreeing to any post-2020 emissions cuts.

Liberal sources told Fairfax Media that Environment Minister Greg Hunt is likely to be forced to step in and fight off the motion on Saturday by asserting the Abbott government accepts climate change is real and is willing to work with other nations to combat its effects.

The timing of the intervention will be a headache for Mr Hunt who has over recent months moved the government towards accepting tougher emissions targets, as revealed by Fairfax Media on Tuesday.
