(75)Contracting authorities that wish to purchase works, supplies or services with specific environmental, social or other characteristics should be able to refer to particular labels, such as the European Eco-label, (multi-)national eco-labels or any other label provided that the requirements for the label are linked to the subject-matter of the contract, such as the description of the product and its presentation, including packaging requirements. It is furthermore essential that those requirements are drawn up and adopted on the basis of objectively verifiable criteria, using a procedure in which stakeholders, such as government bodies, consumers, manufacturers, distributors and environmental organisations, can participate, and that the label is accessible and available to all interested parties. It should be clarified that stakeholders could be public or private bodies, businesses or any sort of non-governmental organisation (an organisation that is not a part of a government and is not a conventional business). It should equally be clarified that specific national or government bodies or organisations can be involved in setting up label requirements that may be used in connection with procurement by public authorities without those bodies or organisations losing their status as third parties. References to labels should not have the effect of restricting innovation.
