The German Sustainable Building Council – DGNB e.V. was founded in 2007 and has around 1,200 members, making it Europe’s biggest network for sustainable building.


The aim of the DGNB is to promote sustainability in the construction and real estate industry and instil awareness of building sustainability among the broader population. The DGNB is an independent non-profit organisation. Its certification system offers a planning and optimisation tool for evaluating sustainable buildings and urban districts. It was developed to help organisations enhance the tangible sustainability of construction projects. The DGNB system is based on the concept of holistic sustainability, placing equal emphasis on the environment, people and commercial viability. The DGNB Academy is an education and training platform that has already provided more than 3000 people from over 30 countries with official qualifications in sustainable building.

Motivation of DGNB being a part of G17

With its Sustainable Development Goals (SDGs) published in January 2016 the United Nations has structured and formulated 17 universal objectives for the sustainable development of our planet for the first time. Since the SDGs came into effect they have already had a great impact on companies, cities and countries worldwide. They are being used to set up strategies and to put own activities into a global perspective.

Despite all these efforts there is still not enough positive change as time flies. This also includes the areas of buildings and cities. We are aware of the critical extent of resource consumption, carbon emissions and waste generation caused by the construction sector but our actions resulting from this understanding are not enough. In this highly diverse sector there is an urgent need to collaborate. We need to shift the present conversations away from only signing pledges and discussing about existing problems that we all know about. We need to shift this towards showcasing and developing appropriate solutions that are scalable on a larger level. In order to make a fundamental change within our built environment it is crucial that we start sharing knowledge and experience and begin to work together beyond the borders of sectors and countries.
