About Greenings
Collaboration in action for a sustainable future.
We work together
No single sector can solve global challenges alone. By bringing together people from government, business, finance, academia, and civil society, we create the space for collective progress.
We listen to every voice
Diverse perspectives lead to better solutions. We make room for all who are willing and able to contribute—balancing environmental, social, and economic needs through a systems lens.
We turn ideas into action
Practical, forward-thinking approaches are what move the needle. Our methods respect real-world constraints and help members turn ambition into impact.
The story so far
Greenings is an independent, not-for-profit network connecting decision-makers, experts, and institutions across sectors to tackle sustainability challenges head-on.
Founded in 2009 as a student initiative at the University of Basel and ETH Zurich, Greenings was created by a group of undergraduates—among them our current Chair, Dennis West—who believed that real change requires collaboration across boundaries. Their early focus on climate change, biodiversity loss, and social inequality set the tone for a long-term mission rooted in purpose and ambition.
Over the past 15 years, Greenings has grown into a respected network known for driving cross-sector collaboration, influencing policy, and shaping practical solutions to global challenges. Our work has received support from leading institutions and has helped to build a more connected, coordinated approach to sustainability.
Now, in 2025, Greenings enters a new chapter. With a newly established Board and Steering Groups, we’re expanding our reach and sharpening our focus on systems-level impact. What began as youthful idealism has become a powerful and pragmatic force for real-world progress.
Our vision
We aim to transform how sectors work together to tackle complex sustainability challenges—leaving a legacy of proven frameworks, lasting partnerships, and real-world impact through collaboration.
Greenings is powered by a small, dedicated team and guided by a global network of experts and leaders. Meet the people behind the mission.
