NetworkNature is driving forward the standardisation of Nature-based Solutions (NbS) across Europe, helping to turn research results and policy ambitions into real-world, scalable impact.
Between 2024 and 2025, the project worked closely with more than 80 EU-funded NbS initiatives to build awareness, share guidance, and initiate concrete action on standardisation. Supported by the Horizon Standardisation Booster, NetworkNature organised a series of workshops and consultations that engaged over 140 stakeholders from the NbS Task Forces. These sessions explored how standards can improve the quality, comparability, and replication of NbS — and how they can accelerate their uptake in cities, regions, and markets.
One key outcome was the launch of a CEN Workshop Agreement (CWA) by the VARCITIES project in early 2025, with others like NATURANCE now following suit. These CWAs mark an important step toward creating shared reference points for NbS performance, benefits, and governance.
To increase the reach and impact of this work, NetworkNature has also established a formal liaison with the European Committee for Standardization (CEN/TC 465 – Sustainable Cities and Communities). Through this collaboration, the project is contributing directly to the first European standard on NbS Terminology (prEN 18140). This work ensures that European efforts align with global frameworks such as the IUCN Global Standard for NbS and ISO/TC 331 on Biodiversity.
“Standardisation is a bridge between innovation and implementation,” says Monika Heyder (ICLEI Europe), who leads this work. “By creating shared understanding and consistent approaches, we can help mainstream Nature-based Solutions as credible, effective tools for sustainability and resilience.”
The interim report on standardisation activities summarises these achievements and outlines next steps for continued collaboration with European and international standardisation bodies. A final report, including lessons learned and recommendations, will follow in 2026.
