Top 10 Global Urban Green Space Ecosystem Service Valuation
This ranking is based on the 2026 urban ecological economics model, evaluating the annual economic value of urban green spaces in major global cities, including air purification, carbon sequestration, cooling effects, and runoff regulation. It quantifies the core contribution of natural capital to urban sustainability.
Interesting Facts & Summary
As of 2026, Singapore maintains its top position in global urban green space ecosystem service valuation. Despite a land area of only ~735 sq km, the nation's transition from a 'Garden City' to a 'City in a Garden' has pushed per capita green coverage to over 70 sqm. Notably, the economic value of its green infrastructure—ranging from carbon sequestration and air purification to microclimate regulation—exceeds $12 billion annually. This effectively offsets the massive energy costs associated with the urban heat island effect and serves as a pillar for the nation's green finance competitiveness. In stark contrast, many megacities of similar density yield only one-third of this value, highlighting the immense leverage of vertical greenery and precision urban ecological management.
