NbS Policy Tracker Series

The NbS Policy Tracker, developed by N4C in collaboration with Arboretica, is the most comprehensive global analysis of nature-based solutions policies to date. It documents how governments embed NbS into national legislation and budget instruments—covering laws, regulations, strategies, and major public investment programs. With a database of 1,546 policies across 190 countries and regions, the Tracker combines automated data collection with expert review to highlight effective policy models, enabling conditions, and critical gaps.
