Environmental Wellbeing Index
OngoingThe Environmental Wellbeing Index (EWI) is a global composite index that measures the health and regenerative capacity of Earth's natural systems — soil, water, air, and biodiversity — across every continent, ocean, and country. It tracks how far industrial activity, technology, and human consumption have pushed these systems beyond their natural recovery limits, while also crediting nations for restorative and sustainable contributions. By combining land and ocean data with country-level accountability, EWI aims to give the world a shared, actionable measure of ecological health — much like GDP measures economic output or HDI measures human development.
