Impact assessment gathers and presents evidence that helps in determining possible policy options and their comparative advantages / disadvantages. The impact assessment runs parallel with and feeds into the development of the Commission’s proposal.
Impact assessments accompany legislative, regulatory or other policy proposals which have an economic, social and / or environmental impact and which are presented in the Commission's Work Programme or Annual Policy Strategy. Impact assessments are carried out before the proposed activity is adopted.
In DG MARKT, the responsibility for carrying out impact assessments is shared between the operational unit concerned and unit B2, with the former being the lead service.
Detailed information about Impact Assessment in the European Commission can be found on the website of the Secretariat General.
