In the future, Kera will be a low-emission model area of digital solutions and circular economy. Biodiversity will also be considered in the planning of the area. In January 2022, a nature value review was launched in Kera to survey the current state of biodiversity in the area and plan the measures to safeguard and improve the natural values of the area also in the construction.

Alongside climate change, biodiversity loss is one of the most significant current global challenges. The City of Espoo has been combatting climate change for years, and in the new Espoo Story, the fight against biodiversity loss has also been raised as a key target. The nature value review of Kera complements the Carbon neutrality road map for Kera completed in autumn 2021.  

When the SOK logistics centre was built in Kera in the late 1960s, nature had to give way to warehouses and asphalt. The aim of the construction of the new Kera is to safeguard the biodiversity of the area and even improve it by building new high-quality green environments. “Traditionally, in dense urban environment, there is less and less room for nature. It is important to identify the kinds of biodiversity improvement measures we can take in the constructed environment and to implement the best possible measures. By constructing a dense city, we are also supporting the preservation of natural areas elsewhere,” says Specialist Rosa Väisänen. 

The currently started nature value review establishes a calculated value for biodiversity that allows us to demonstrate changes in biodiversity. The review will use an urban biodiversity metric to determine the current state of biodiversity and assess the impact of the planned construction.  

The nature value review sets a target level and surveys potential measures to further improve biodiversity in the future. Construction solutions that enhance biodiversity include, for example, storm water systems founded on nature-based solutions, green roofs and walls, the promotion of native species and multifunctional planting groups, and the replacement of lawn fields with natural meadows that have more diverse species. 

The nature value review is expected to be completed in April 2022. You can follow the progress of Kera’s planning at

The Kera nature value review is carried out as part of the Implementation Pathway for Environments that Accelerate Sustainable Growth KETO project. The project is funded with the European Union REACT-EU ERDF funding, which is part of the European Union’s response to the COVID-19 pandemic.
