Analysts agree that public opposition is one of the main factors that hinder ambition in many countries’ carbon pricing policy agenda. This article argues that motivated reasoning contributes to this opposition by inducing the public to underestimate the effectiveness of carbon pricing to mitigate climate change and yield co-benefits. This article also argues that measures of implicit carbon pricing can help overcome public opposition to carbon taxes and emissions trading schemes due to motivated reasoning. These measures are becoming increasingly available thanks to recent work by the International Monetary Fund, the Organisation for Economic Co-operation and Development and private-sector actors, and therefore they offer a potential instrument for reducing public opposition to carbon taxes and emissions trading schemes in various countries. A strength of the approach proposed in this article – compared to some of the mainstream approaches to risk regulation – is that it tries is to keep the regulation of climate risks in line with public attitudes towards these risks.

21 To have a sense of how commonly this strategy is used in practice (consciously or not), it is sufficient to look at the evolution throughout time of the levels of carbon prices around the world.

86 Notice that, in some countries, public opposition to fuel subsidy reforms might be more politically contentious than carbon taxes and ETSs. For instance, in 2017, protests erupted in Mexico against a sharp cut in fossil fuel subsidies; see D Agren, “Mexico Protests: How Gas Prices Lit the Flame Under a Quietly Smoldering Rage” (The Guardian, 9 January 2017) <https://www.theguardian.com/world/2017/jan/09/mexico-gasoline-price-protest-gasolinazo>.
