European cities embrace nature-based solutions and other urban transformation stories you need to read

Nearly all European cities are utilizing nature-based solutions (NBS) to mitigate the impacts of climate change, according to a report by the European Environment Agency (EEA).

NBS, which includes 'maintaining, restoring and creating new parks and urban forests, planting individual urban trees, improving urban water management and greening buildings', appears in 91% of the local climate action plans the EEA surveyed.

"The multitude of co-benefits NBS can bring, such as biodiversity gains, recreation potential and mental well-being, means that they are also increasingly recognized as 'no regret' measures," says the EEA.

The report spotlights Germany, which has become a global leader in greening practices. German cities use green roofs and facades to enhance rainwater absorption, cool buildings, improve air quality and promote public wellbeing, it says.

In 2023, temperatures in Europe were above average for 11 months, including the hottest September on record.

Urban centres contribute 80% of the world’s GDP, but an estimated 44% of global GDP ($31 trillion) generated in cities is vulnerable to disruption due to nature loss.

Despite this, only 37% of the world’s 500 most populous cities have developed a dedicated strategy focused on nature or biodiversity preservation.

To accelerate the transition to nature-positive cities, the World Economic Forum, in collaboration with Oliver Wyman, has published guidelines for creating a sustainable, resilient urban environment.

Coordinated city action is vital to achieving the goals set by the Kunming-Montreal Global Biodiversity Framework (GBF), but also strategically necessary given the climate-, health- and infrastructure-related challenges arising from existing unbalanced relationships with nature and the biosphere.

The report is the first in a series of Nature Positive Transitions reports series, which outlines the pathways cities can take to halt and reverse nature loss by 2030.
