In the previous article we made a case to have a shared language for regeneration in the built environment. We explained how it would help communicate and coordinate industry’s actions; as well as avoid the pitfalls of sustainability paradigm such as greenwashing. In this article we explore the importance of having protocols that ensure due processes are followed and recorded in a transparent, permanent and immutable way. This allows for tracking, measurement and validation of impact over time, enabling a shared source of truth, which in turn helps us write better stories of regeneration backed with real, verifiable data. If we are to foster a culture of regeneration, a shared source of truth goes a long way to build better systems that are rooted in symbiotic relationships between humans and nature.
