30x30 (https://en.wikipedia.org/wiki/30_by_30) is a global initiative proposed in the Kunming-Montreal Global Biodiversity Framework to conserve 30% of the area represented by Earth’s land, water and oceans. This goal has been adopted by many countries and non-governmental organizations, including The Nature Conservancy and the United States in the Biden administration’s Executive Order 14008 (Section 216) later a key element in the launch of the America the Beautiful initiative in 2022.
OpenStreetMap has adopted International Union for Conservation of Nature standards for describing protected areas, including parks, nature reserves, and other lands. As a free, open-source, community-driven and collaborative geographic feature database, OpenStreetMap is a useful tool for assessing progress towards this goal. Continual updates, world-wide coverage, native-language support and a robust open data working group governance structure; OSM is perhaps the best “live” tracker towards accomplishing this goal.
