The quest to measure our relationship with nature

The United Nations is working on a Nature Relationship Index (NRI) to measure how well countries interact with the natural world. The NRI aims to shift the narrative from humans being destroyers of nature to fostering a green, abundant world. The index will assess three key questions: whether nature is thriving and accessible, if it is being used with care, and if it is safeguarded. The NRI will debut alongside the 2026 Human Development Report, encouraging countries to compete and improve their scores. The goal is to engage people's hopes and dreams for a better relationship with nature.
