Due to differences in greenhouse-gas abatement costs within the industrial sectors, there is an ongoing discussion on potential negative competitive effects of climate and energy policies. This article argues that policymakers must acknowledge the relative performance of industrial operations parallel to the competitors, the compulsoriness of policies, and the harmonization of policies accordingly. To this end, the authors suggest a tool aimed for robust participatory policy evaluations at decision-maker levels. The tool promotes policy learning, transparency, and consensus building, hence contributing to more effective and efficient policy design and management process. The tool is exemplified in a Swedish context.
