WGIN is proud to support the #RestoreNature campaign!   

Nature is essential to our survival. To prevent the increasing fires across the continent. To resist the floods destroying European homes and livelihoods. To generate healthy ecosystems to produce food in the long-term. Nature is our biggest ally in the fight to mitaget and adpat to the climate crisis. And we need nature for our mental wellbeing and health. But did you know 80% of Europe’s nature is in bad shape? 

With the Naturel Restoration Law, Europe has a once-in-a lifetime opportunity to bring back nature. What makes this opportunity unique is that this law will legally oblige EU countries to restore a set amount of nature, including in cities. The inclusion of green infrastructure is a core solution for the restoration of nature in urban areas, which will lead to many co-benefits for biodiversity and its inhabitants. 

Together with many different organisations working on the restoration of nature, WGIN is calling for an ambitious Nature Restoration Law, currently under scrutiny in the European Parliament and the Council of the European Union. To support this initiative, you can send a picture of nature you would like to see restored and a letter to your decision makers by using this specific tool.

We further encourage you to you fill in your personalised message with reference to urban green infrastructure: 

“Restoring nature also means the uptake of urban green infrastructures such as vegetated roofs and walls, which have been increasingly considered as a tool to both mitigate climate change and to help urban areas adapt to its growing impacts, while increasing people’s wellbeing. This is especially important in our fast-changing climate, where heatwaves and severe droughts such that of summer 2022 become a more common occurrence. I call on you to restore nature and secure a safer future for us all!”

Green roofs for urban rainwater and stormwater management

The new paper by WGIN’s EU Chapter “Green Roofs for Urban Rainwater and Stormwater Management”, explores how green roofs can contribute to more climate-resilient cities. The paper highlights their role in managing rainfall, reducing pressure on urban drainage systems, and delivering wider benefits for biodiversity, urban cooling and well-being. Published ahead of the European Commission’s forthcoming Climate Resilience Framework, the paper underscores the importance of integrating green infrastructure and nature-based solutions into urban planning and climate adaptation strategies.

Green roof research measures performance, but not yet people

New study maps 25 years of green roof literature and finds affordability and social equity nearly invisible. Submitted by WGIN members Ferre Maes and Bert Belmans In a study published in City and Environment Interactions, WGIN members Ferre Maes and Bert Belmans, together with Roméo Delcroix (Vrije Universiteit Brussel), analysed more than 3,500 green roof articles published between 2000 and 2025. They tracked how often 13 performance dimensions appear in titles, abstracts and keywords. The results show a clear imbalance. Stormwater management appears in 37% of publications, urban heat island mitigation in 19% and building energy in 18%. Affordability (1.7%) and social equity (3.2%) are among the least visible topics in the field, and have remained marginal for 25 years. The study does not show that green roof implementation is inequitable; it shows that the published evidence cannot yet answer this question. Research on parks, urban greening and green stormwater infrastructure engages with affordability and equity far more often, which shows this gap can be closed. There is no reason green roof research can’t do the same. A call to action WGIN’s mission is to advocate and promote the integration of green infrastructure in urban planning, globally. But planning decides who benefits, and evidence on who benefits is largely missing. If we want cities, funders and residents to trust green roofs as a public good, we need to be open about what we know and what we don’t. That openness is also an opportunity: evidence on affordability and equity is what opens the door to public funding, social housing and neighbourhoods green roofs have yet to reach. We call on our community to: Count people, not just performance. In research papers, project reports and case studies alike, report cost, access and who benefits alongside technical results. In publications, name affordability and equity explicitly in titles and abstracts so the work can be found. Plan for equity from the start. Build these questions into green roof strategies, subsidies, projects and research calls, before roofs are built. Make costs transparent. Manufacturers, installers and researchers alike can share life-cycle cost data, from installation and maintenance to lifespan and savings, in a consistent and anonymised format, so support schemes can reach beyond those who can already afford a green roof. Neighbouring fields already study performance and people together. The green roof community can too! Read the full paper here: 10.1016/j.cacint.2026.100476 (open access)

WGIN Global Green Roof Professional Development and Accreditation Programme – Call for National Associations Partners

In April 2026, WGIN launched the Global Green Roof Professional Development and Accreditation Programme. This initiative aims to establish an internationally recognised professional training programme focused on green roof design, installation practices, maintenance, and long-term performance. The online training is designed to deliver a set of universal quality best practices rooted in knowledge rather than technical skills. The programme’s intent is to accelerate the development of national and regional green roof markets by providing online training and accreditation.  The Global Green Roof Professional Development and Accreditation Programme is now looking for two national associations to design national training modules and examination questions based on the core curriculum developed under this project. The application process is open until 7 September. Selected national associations will be contacted by 21 September. For more information, see the call for interest. To apply for the call of interest, visit this link.
