Choosing green and blue over grey to improve cities’ climate resilience

Climate change is making extreme weather events more frequent and severe, increasing the vulnerability of Europe’s cities . Heatwaves, flooding, droughts and water scarcity are already affecting citizens, infrastructure, and economic activity, and continued urbanisation further intensifies these challenges. As the European Chapter of the World Green Infrastructure Network (WGIN), we publish today a new position paper ahead of the upcoming publication of the European Climate Resilience Framework, planned for release during Q4 2026. We call the Commission to ensure that the t Climate Resilience Framework: Embed a mandatory “resilience-by-design” principle across EU planning, public spending, and sectoral policies. Establish a clear EU definition of a climate-resilient city, adaptable to national and regional contexts. Require climate risk assessments for urban areas, including pathways to scale up blue-green infrastructure solutions. Prioritise urban areas, buildings, and critical infrastructure, ensuring renovation policies deliver future-proof, climate-resilient buildings. Strengthening climate resilience in Europe must start with cities and the built environment. Read our full set of recommendations here.

Policy Guidance: Making European Cities healthier, more resilient and beautiful

  WGIN’s European Chapter and EFB have released a new set of implementation guidelines to support the national adoption of European legislation. The document provides practical guidance on how to implement legal provisions that can accelerate the deployment of green roofs and green walls, generating multiple benefits for people, cities, and the environment, including climate resilience, increased biodiversity and enhanced urban wellbeing. They offer direction on implementing key EU legislative instruments: Energy Performance of Buildings Directive (EPBD) Energy Efficiency Directive (EED) Urban Waste Water Treatment Directive (UWWTD) Nature Restoration Regulation (NRR) With scientific evidence and a set of practical steps, the document shows how effective implementation of green roofs and walls can support meeting EU obligations and climate goals.

WGIC26 – Closing the gap between communities of practice for green infrastructure and health

  WGIN’s mission statement is “The World Green Infrastructure Network advocates for optimal use of green infrastructure in the urban built environment for the health and well-being of people and the planet.” WGIN has in recent years acknowledged a gap in the attention we’ve given to the human health and well-being benefits of urban green infrastructure. The next World Green Infrastructure Congress, WGIC26, in Barcelona in October 2026 will address this gap by dedicating one of its three thematic tracks to health and well-being. Our congress hosts, the University of Lleida, expect this track will contribute to increased focus on health and well-being within our community of practice, and will hopefully contribute to increased interdisciplinary collaboration with the health sector. WGIN members and stakeholders are encouraged to support and help distribute the soon to be published call for papers for WGIC26 through their websites, social media and personal networks and to assist in recruiting the health community to join us in Barcelona. Through stronger interdisciplinary collaboration we can foster greater recognition and support for urban and building integrated green infrastructure and its relevance in health research, policies and practices.

Green Street Standards – A Breakthrough in Urban Green and Blue Infrastructure (Wrocław, Poland)

Local stormwater management in a rain garden collecting runoff from S. Drabika Street, Wrocław (Poland). (Photo: J. Rubaszek). Planning and designing green and blue infrastructure (GBI) as an integral part of urban streets – as is widely recognised – requires support in terms of organisation, funding, legislation and social awareness. As demonstrated by the case of Wrocław – one of the fastest-growing cities in Poland – standards can serve as an effective tool for supporting the implementation of GBI. These standards include guidelines and model solutions that integrate spatial, technical, and environmental aspects. Before establishing these standards, introducing green and blue infrastructure to Wrocław’s streets – even in newly planned projects – posed significant challenges. The main obstacles included insufficient space, the location of underground utility networks in areas that could otherwise accommodate trees, and relatively low public awareness of the importance of creating proper conditions for vegetation, especially large street trees.
