Laws and regulations affect the daily lives of businesses and citizens. High-quality laws promote national welfare and growth, while badly designed laws hinder growth, harm the environment and put the health of citizens at risk. This report analyses practices to improve the quality of laws and regulations across all 28 EU Member States and the European Union. It systematically assesses the use of evidence and stakeholder participation in the design and review of domestic laws and regulations based on the OECD Indicators of Regulatory Policy and Governance. It also provides insights into individual Member States' use of regulatory management tools as they relate to EU laws. The report presents good regulatory practices and highlights areas that should receive further attention and investment.
