This study aimed to support the Commission in identifying and analysing policy options for possible revision of the RIS Directive. IAs aim to collect evidence (typically starting from the evaluation results, in this case especially the Commission Staff Working Document (SWD)2, as well as older ones), to assess whether future legislative or non-legislative EU action is desired and justified to update an intervention and, if so, how it can best be designed to achieve the relevant policy objectives in the most effective and efficient way. In particular, IAs: Identify and describe the problem to be tackled Establish objectives for the EU action Formulate policy options, assess their potential impacts and, where appropriate, identify a preferred option Set out how the expected results will be monitored and evaluated An IA is required for Commission initiatives that are likely to have significant economic, environmental, social and other relevant impacts or which entail significant spending, and where the Commission has a choice of policy options. IAs support the policy-making and decision-making process by feeding the evidence-based information needed to take an informed decision. IAs thus lead to more informed decision-making and in this way contribute to “better regulation” that delivers the full benefits of policies at minimum cost, while upholding the principles of subsidiarity and proportionality.
