Sustainability and social responsibility can be measured trough several dimensions. This study aims to understand which ones are important for the consumers and how much information they are expecting on them. Too little information may be irritating for some consumer, too much may overload them. In this paper, we have developed and evaluated four different types of sustainable and socially responsible labels inspired from a multi-criteria decision aid approach. Each one has an additional piece of information. The research has evaluated the corporate social responsibility performance of three food companies operating in the Sannio area (South of Italy) that produce respectively oil, pasta and wine. The sustainability of their branded products has been measured and four different labels indicating their sustainable performance to internal and external stakeholders have been created. The elaboration of a standardized labelling system on food products, outlining their green, social and ethical credentials, is important to avoid to confuse the consumers and producers.
