This article considers the puzzle of Norway and Canada, two countries that have adopted ambitious Paris Agreement targets yet are also major fossil fuel exporters. To date, both countries have taken full advantage of the international convention that assigns responsibility only for emissions within a country’s borders. However, climate activists, First Nations, and green politicians increasingly have challenged fossil fuel production via campaigns centered on issues salient to voters in nonproducing regions: opposing new exploration licenses in Norway and pipelines in Canada. While supply-side campaigns have sometimes succeeded in ending expansion, neither country has seriously entertained restricting current production. We attribute these outcomes to continued public support for fossil fuel–driven prosperity; institutions that assign responsibility for production and climate to different government agencies; and the success of counternarratives that unilateral supply restrictions are futile, prosperity from petroleum exports will fund domestic clean-energy transitions, and gas exports advance global climate action.
