London came out on top with 3,000 parks and green spaces. Second on the list was Berlin with 2,500 parks, and third was Vienna with 2,000 parks. Compared to cities like Barcelona and Rome we're miles ahead, as those cities have 114 and 63 green spaces respectively.

This is a subject of friendly rivalry, but in 2026, London is statistically greener than Berlin in terms of total public green space percentage. Approximately 47% of London is classified as green space, which includes its eight Royal Parks, thousands of neighborhood squares, and the vast "Green Belt" protecting the city's periphery. London is technically classified as an "urban forest" because it has more trees than people. Berlin, however, often feels greener to the average visitor because its greenery—like the massive Tiergarten or the repurposed Tempelhofer Feld—is more centrally integrated and accessible. Berlin boasts about 30–35% green space, but it ranks higher for "biodiversity" and wilder, less manicured parklands. While London wins on the raw map data, Berlin is often cited as a leader in sustainable urban "livability." In 2026, London is furthering this lead with projects like the Camden Highline and expanded tree-planting initiatives under the "fairer, safer, greener" vision of the city's leadership.
