Domestic carbon pricing policies may impose adverse competitiveness risks on energy-intensive firms competing with foreign firms that may bear a lower carbon price. The risks of competitiveness effects include adverse economic and environmental outcomes, which can undermine political support for carbon pricing. Competitiveness policies, such as border tax adjustments, output-based tax credits, and related policies, also carry potential risks: unfavorable distributional outcomes, less cost-effective, and harming international trade and climate negotiations. This paper reviews the theoretical and empirical research on competitiveness risks and the risks posed by competitiveness policies, and presents two alternative frameworks for evaluating competitiveness policy options.
