In theory, market-based regulatory instruments correct market failures at least cost. However, evidence on their efficacy remains scarce. Using administrative data, we estimate that the EU ETS – the world’s first and largest market-based climate policy – induced regulated firms to reduce carbon dioxide emissions by 8-12% compared to unregulated firms, a necessary condition for climate change mitigation. We find no evidence of outsourcing to unregulated firms or markets; instead firms made targeted investments, reducing the emissions intensity of production. These findings suggest that the EU ETS induced global emissions reductions, a necessary and sufficient condition for mitigating climate change.
