Procurement: With regard to procurement, why are the European Union rules inflexible with regard to the use of social issues within contracts?

Three reasons have been given for this by the European Commission. Firstly, social issues have the potential to favour national or local providers, thus working against the principle of open markets across the European Union and in other theatres. Secondly, social issues can incur large costs without delivering benefits. Thirdly, some of the required social outcomes could be delivered more efficiently in other ways.
