More about WGIN

Since 2009 WGIN has expanded globally to now represent 22 National Associations and has held ten World Green Infrastructure Congresses. WGIN has established supportive working research committees and has an active enthusiastic board of directors representing eleven nations. 

As a registered Not-For-Profit association our primary driver is passion and a strong united belief that our world can be developed progressively with innovation however there needs to be a balance; respect and synergy with NATURE. The transition from ‘grey to green infrastructure’ for building and urban design is what drives our efforts as a collaborative global network because ” vegetation makes it possible”


Leaders of several national green roof organizations first discussed the formation of an international green building technology organization in Chicago in 2003, and at subsequent green roof events in Portland (2004), Basel (2004), and Washington (2005). It was in Boston in 2006 that the first steps towards a legally chartered organization were taken.

The following year, 2007, at the Green Roofs for Healthy Cities “Greening Rooftops for Sustainable Communities” Conference in Minneapolis, WGIN held it’s first official meeting. Germany’s Manfred Köhler was named chairperson, and North America’s Steven Peck accepted responsibility for ongoing formal activities to move the organization forward. With all legal aspects of the organization settled by 2008, active membership was pursued at the GRHC Conference in Baltimore, and six organizations from seven nations came on board as Founding Members of WGIN. Given the rapid growth in the green roofs, walls and infrastructure industry, WGIN targeted strong organizational growth over the next several years. It is a challenging world, and green building technology is one solution to tackling the impacts of climate change that affect us all. WGIN still strongly believes cooperative effort is needed to work for a better, greener and more sustainable world.


As a decision at the AGM in Nantes, France in 2013, the name was changed to the World Green Infrastructure Network (WGIN). As the industry had evolved, so too had the concept of green city urban planning and a transition away from traditional grey infrastructure practices. Our association responded to support and promote all components of green infrastructure whilst retaining a primary focus on Building Integrated Vegetation systems (BIV). Our primary manifesto may be refined to “vegetation makes it possible”


Our primary objective remains to foster support for National associations to expand and contribute to a global green revolution. Our most active support to nations is holding the World Green Infrastructure Congress in a different nation annually since 2009. To financially support our congress and research committees we accept memberships from Corporations; Nations; Companies and Individuals. WGIN also welcomes likeminded affiliations with other associations such as the EU Environmental Agency and EFB, amongst many others.

Please consider membership to assist us with our work to mitigate the impacts of climate variability and improve urban liveability for global communities.

WGIN PUBLICATION: “Multifunctional Urban Green Infrastructure”

The book is a fruitful collaboration between institutions, organizations, companies and experts in green urban infrastructures under the common idea that Humanity needs sustainable development, where urban areas must seek ecosystem services. The solutions to many problems can be solved under the experience of nature that for thousands of years has adapted to the environment. 


We present the experience of specialists in a wide range of disciplines, which deal with issues such as mimicry, energy-saving, landscape or urban planning.


Throughout 352 pages, the publications include 17 chapters with 30 authors from 17 countries. There is a special section, which describes the international and national organization of 30 countries. Colour photography, tables and graphs facilitate reading and understanding the theme of green urban infrastructure.
