About Us
The global community has made major strides in setting goals to limit global warming, and achieve sustainable development for all. However, action on these goals is insufficient and questions remain on how to achieve them. Through our action-oriented research, and with our global and local partners, we explore pathways to deliver on these goals.
TMG Think Tank
Klaus Toepfer
We focus on the transformations needed to achieve inclusive and sustainable development.
“Politics is the art of turning what is necessary into what is possible”
Prof. Klaus Töpfer
As a think tank, we see one of our key roles as catalysing such change processes.

Our Guiding Principles
Image1
Reflective
Change must match the inherent complexity of inclusive sustainable development, while still relying on feasible solutions. This requires a reflective and adaptive approach to identify pathways towards sustainability.

Visionary
We know that it is not possible to create a more equal and sustainable world without fundamentally changing how we interact with each other and the planet. We believe that we need to work together to overcome vested interests and achieve transformative change.

Practical
We work closely with partner organisations at different levels to co-design solutions to pressing sustainability challenges. To develop adapted innovations, we reconcile divergent perspectives, interests, capacities, and knowledge systems.

Engaged
We recognise that acting on proposed solutions to sustainability challenges at different levels requires confronting power relations and building broad-based alliances to create the necessary leverage for change. Through our projects, we strive to initiate change processes that last. 
Our Team
We are a diverse and multinational team of dedicated professionals covering a broad range of thematic fields.
