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.
