Public acceptability of climate-motivated rationing

Recent reports from climate scientists stress the urgency to implement more ambitious and stringent climate policies to stay below the 1.5 °C Paris Agreement target. These policies should simultaneously aim to ensure distributional justice throughout the process. A neglected yet potentially effective policy instrument in this context is rationing. However, the political feasibility of rationing, like any climate policy instrument, hinges to a large extent on the general public being sufficiently motivated to accept it. This study reports the first cross-country analysis of the public acceptability of rationing as a climate policy instrument by surveying 8654 individuals across five countries—Brazil, Germany, India, South Africa, and the US—on five continents. By comparing the public acceptability of rationing fossil fuels and high climate-impact foods with consumption taxes on these goods, the results reveal that the acceptability of fossil fuel rationing is on par with that of taxation, while food taxation is preferred over rationing across the countries. Respondents in low-and middle-income countries and those expressing a greater concern for climate change express the most favourable attitudes to rationing. As political leaders keep struggling to formulate effective and fair climate policies, these findings encourage a serious political and scientific dialogue about rationing as a means to address climate change and other sustainability-related challenges.
