3% of the area is green (parks, sport, nature), against 16% in the Netherlands.
Every share is calculated as a percentage of the TOTAL area (land and water together, peiljaar 2022); water is therefore one of the slices itself, not a separate whole. Green is the sum of recreational terrain (parks, sport fields, allotments, day recreation) and natural terrain (forest, open natural terrain) — agricultural land is not counted as green here.
