As the Baillieu government prepares to reveal the future of Victoria's climate change laws, a poll has found two-thirds of Coalition voters think the state has a responsibility to cut greenhouse gas emissions.
The Essential Media poll of 1009 Victorians, commissioned by conservation group Environment Victoria, found 76 per cent believed the state government should cut emissions and not leave it to the federal government to take action through a carbon tax or other steps.
Among Coalition voters, 66 per cent said the state had a responsibility to cut emissions.
Victorians want the state government to act despite belief in climate change being split between those who think that it is caused by human activity (47 per cent) and those who think it is either due to natural variation or not happening at all (44 per cent).
The poll comes as the state government is due to this month release a review of the Climate Change Act introduced by the previous Labor government, which includes a target of cutting Victoria's emissions by 20 per cent this decade.
The Baillieu government has wound back some clean energy programs and fuelled expectations the target could be reduced or scrapped.
Other findings from the poll conducted in December and January were:
Fifty per cent said the laws were not fair.
