The Ministry of Ecology, Sustainable Development and Energy embarked on this journey in 2010 with a call for tenders to which 168 companies and organisations responded. Among those were Casino who was already working with food manufacturers, environmental experts from the BIO Intelligence Service and the ADEME on carbon labelling[3]. In response to the tender, Casino stepped up its actions and in partnership with ADEME/AFNOR[4] developed its environmental label.
