Digital platform that aims to engage people and businesses in behavior-changing initiatives regarding climate, energy, environment, and social sustainability.

Launched in September 2017 at De Ceuvel, a sustainable urban community in Amsterdam, the Jouliette is an example of how a new and developing technological innovation like blockchain can be used by communities to manage and share their own energy production and consumption. The initiative aims to investigate how community energy tokens can enable greater self-sufficiency in communities. The Jouliette can be used as a means to trade goods at the De Ceuvel Cafe, to facilitate a local time-banking system, and to integrate other intra-community services, such as a car-sharing program.
