How regulation is different from Directive (European Union)? Definition from EU
A “regulation” is a binding legislative act. It must be applied in its entirety across the EU.
A “Directive (European Union)” is a legislative act that sets out a goal that EU countries must achieve. However, it is up to the individual countries to devise their own laws on how to reach these goals. One example is the EU single-use plastics directive, which reduces the impact of certain single-use plastics on the environment,
A “decision” is binding on those to whom it is addressed (e.g. an EU country or an individual company) and is directly applicable. For example, the Council issued a decision on allowing Croatia to adopt the euro on 1 January 2023. The decision related to the country only.
