The development of the Standard for Animal Welfare is grounded in both the scientific data and the results of the research carried out in this thematic field, as well as in the social and economic data of the sector, as identified by cow farmers, the industry and consumers of cow’s milk. The innovative elements of CoWel refer to the method of its constitution, with the participation of all potential users, as well as to the consideration of qualitative parameters at the level of primary production and the Greek market, to formulate the applications proposed. The CoWel Standard will be implemented for the first time at national level on a voluntary basis by users, cow farmers and processors. The approach to the implementation of the project allocates responsibilities for the coordination of work, but also the expected benefits, on equal terms between all partners.
