Tony Abbott is facing growing discontent among his colleagues about his $3.2 billion Direct Action plan to combat climate change, a policy once described by Malcolm Turnbull as rubbish.

Liberal MPs Mal Washer and Dennis Jensen say the Coalition should review or consider abandoning parts of the policy in the light of ''dire economic circumstances''.

Discontent about the Coalition's environment policy comes in the same week as MPs broke ranks to publicly criticise Mr Abbott's paid parental leave scheme as economically irresponsible.

Meanwhile, the release of the Coalition's industrial relations policy on Thursday too - as expected - drew fire from the business community for not going far enough.
