Finn was a critic of the federal government's carbon pricing scheme, stating in the Victorian Parliament in 2013 that "there has been no global warming for 17 years". He has attacked the climate change documentary "An Inconvenient Truth", as well as reports on the subject in the British newspaper "The Guardian". He has claimed that global warming is an invention of the "international left", suggesting that "it raised a few dollars and promoted its own political interests. It came up with a thing called global warming", which he labelled "nonsense". He went on to say that "we have to come to a conclusion that climate change is not so much a scientific thing as it is a political thing". Finn also told Parliament that "This is a con; the whole thing is a con. Today we are in the Parliament of Victoria wasting our time on something that is largely an invention of the left".
