How effective are climate change policies, and what are the important considerations to ensure they are effective? This column shows that firms respond to climate change policies with regulatory arbitrage so that localised policies aimed at mitigating climate risk can have unintended consequences. Studying the impact of the California cap-and-trade programme, it shows that firms without financial constraints do not reduce their emissions in response to the policy. In contrast, financially constrained firms shift emissions and output from California to other states. In fact, contrary to the policy objective, these firms increase their total emissions after the cap-and-trade rule.

International agreements on ways to tackle climate change are in a depressing deadlock. This column argues that part of the problem is aiming too high. It suggests that slow and gradual progress towards controlling climate change is the only way forward. But this is at least better than waiting for an ideal solution that may never come.
