The Commission is inviting comments on a guidance paper aimed at helping Member States to better evaluate to what extent public support schemes have achieved their purpose and what was their impact on markets and competition. The evaluation of aid schemes is an important element of the Commission's state aid modernization agenda towards more efficient and effective public spending. On the one hand, the state aid reform will enable Member States to grant more aid measures without prior clearance by the Commission. On the other hand, those aid measures which are significant will be assessed more thoroughly than in the past. The guidance paper sets out best practices and key principles, while giving Member States the necessary flexibility to adapt to the specific situations of each evaluation exercise. The Commission's Competition service will then publish the guidance paper on its website and use it as a basis for the evaluations to be carried in the coming years. Comments can be submitted until 24 January 2014. Source: Commission Press Release 22/11/2013 and Commission Public consulations: Modernising state aid through better evaluation
