A recent study (from earlier this summer) that I only just came across shows that the US Republican Party is the only conservative party among many studies that actively and pretty much completely denies the science of climate change. This is not very surprising since the GOP denies science in general and has done so for years. Also, the GOP is the party that is probably more fully paid off by business interests. And, the party seems to represent the rather large fraction of the American public that is cynical about science, and that sees science as part of a Vast Left Wing Conspiracy.
The study is: ore than Markets: A Comparative Study of Nine Conservative Parties on Climate Change and here is the abstract:
Cross-national comparisons of proposed policies of individual parties are an underdeveloped part of the literature on environmental politics in general and climate politics in particular. Although conservative parties are portrayed as skeptical toward adopting climate measures or even supposed to ignore climate change, this study of nine conservative electoral manifestoes nevertheless finds that most of them support climate measures, even in the form of state interventions in the market economy. Market measures are not as dominating as could be expected, but a clear finding is that available fossil reserves seem to have an influence on conservative climate politics. The U.S. Republican Party is an anomaly in denying anthropogenic climate change. Conservative parties as such are not in opposition to climate policies, but the pro-business position is evident in that conservative parties do not challenge coal or petroleum in countries with large reserves of these resources.
