The Public Administration is in charge of distributing public money, investing in products and services necessary to satisfy the needs of society. To this end, bidding processes are launched, through which the State "chooses" (based on a series of characteristics and conditions set forth in the bidding documents) the person(s) or company(ies) suitable to carry out the service, the work, or the product that most closely meets the State's demand. As mentioned above, the bidding documents contain the basic characteristics that the purchase or contract must have in order to be awarded. Therefore, what is proposed in the manuscript is the implementation of a type of bidding process that, in addition to meeting the needs to be satisfied, takes into account environmental protection characteristics and rewards innovation and sustainability of the product or service contracted.
