This Policy Brief presents Barcelona’s strategies for increasing and improving urban green infrastructure. Renaturing cities is essential for adapting urban areas to climate change. For this reason, in 2013, Barcelona initiated its first “Green and Biodiversity Plan 2020,” followed by the “Urban Green Infrastructure Boost Programme” in 2017, a municipal government initiative. The need to update, affirm, and reinforce commitments led to the “Natura Plan 2030” in 2021, which built on citizen participation as an essential part of its development.
