(97)Furthermore, with a view to the better integration of social and environmental considerations in the procurement procedures, contracting authorities should be allowed to use award criteria or contract performance conditions relating to the works, supplies or services to be provided under the public contract in any respect and at any stage of their life cycles from extraction of raw materials for the product to the stage of disposal of the product, including factors involved in the specific process of production, provision or trading and its conditions of those works, supplies or services or a specific process during a later stage of their life cycle, even where such factors do not form part of their material substance. Criteria and conditions referring to such a production or provision process are for example that the manufacturing of the purchased products did not involve toxic chemicals, or that the purchased services are provided using energy-efficient machines. In accordance with the case-law of the Court of Justice of the European Union, this also includes award criteria or contract performance conditions relating to the supply or utilisation of fair trade products in the course of the performance of the contract to be awarded. Criteria and conditions relating to trading and its conditions can for instance refer to the fact that the product concerned is of fair trade origin, including the requirement to pay a minimum price and price premium to producers. Contract performance conditions pertaining to environmental considerations might include, for example, the delivery, package and disposal of products, and in respect of works and services contracts, waste minimisation or resource efficiency. However, the condition of a link with the subject-matter of the contract excludes criteria and conditions relating to general corporate policy, which cannot be considered as a factor characterising the specific process of production or provision of the purchased works, supplies or services. Contracting authorities should hence not be allowed to require tenderers to have a certain corporate social or environmental responsibility policy in place.
