Barcelona is one of the most densely populated cities in Europe.
Given the limited availability of urban green space per capita, Barcelona’s City Council is focusing its attention on enhancing the quantity and quality of green areas and the ecosystem services they provide. The city’s commitment to a green future is demonstrated by policies such as the Barcelona Green Infrastructure and Biodiversity Plan 2020.
