Better regulation for the green transition stress-testing toolkit

Regulation is one of the most powerful tools governments have at their disposal to achieve environmental goals. While the need to address climate change is clear, governments face persistent difficulties in designing, implementing, and evaluating effective environmental regulations. The OECD Better Regulation for the Green Transition Toolkit offers government officials, regulators, stakeholders and experts a tool for assessing the resilience and effectiveness of their national regulatory policy frameworks for the green transition. Developed in collaboration with the Government of Korea, the toolkit features assessment criteria aligned with the design, delivery, and evaluation phases of the regulatory policy cycle. It enables policymakers to identify gaps, evaluate framework robustness, and measure implementation effectiveness in supporting environmental objectives, while recognising trade-offs with other policy goals. This paper emphasises how systemic, inclusive, and adaptive regulatory practices can contribute to accelerating the global green transition.
