Sustainability takes centre stage for consumers, who now prefer to interact with companies that adopt behaviour in line with their values. At the same time, companies are increasingly aware of their social role: they not only can, but must be spokespersons for a valued purpose, supporting social and environmental policies. In this context, every action must be in line with the Sustainable Development Goals (SDGs) of the United Nations 2030 Agenda. Loyalty thus becomes a fundamental driver for involving customers in journeys aimed at achieving sustainability goals, going beyond just business. In this way, companies can create a deeper bond with customers while promoting a positive impact on society and the environment.
