This research offers to explore the effect of gamification to increase engagement towards sustainability. Even though ecology has become a major concern both on an individual and collective level, the words “There is only one Earth”, pronounced in 1972 at the first United Nations Conference on the Environment persists today. While many non-profits and NGOs have been created, their work relies on public and private financial support. Still, their actions are not sufficient despite an increasing global awareness (Ministère de la Transition Ecologique et Solidaire, 2019; GIEC, 2019). There is a need to adopt new behaviors to replace the actual ones. Gamification offers possible lines of approach based on game mechanics designed to create new habits. Sometimes defined as a persuasion technic to influence, it is considered to empower individuals who would be more willing to act and feel on a mission providing a personal satisfaction. Passive donors (limiting their engagement to a financial support) could be replaced or joined by “donactors” personally committed either through a non-profit (sharing information, volunteering) or modifying their habits while sharing good practices at large. The link between gamification and empowerment to preserve the environment opens new research opportunities about the “donactors” types and the associated mechanics.
