How we live and implement sustainability

This is what sustainability means to us

Our approach to sustainability is manifested in our purpose: We co-create living spaces for generations to come. Among the many definitions, we orient towards the definition of sustainability as the possibility that all people and all life on earth can flourish forever.

Sustainability Strategy

Since 2021, we have had a global climate strategy, but this was just a good start. While curbing climate change is one of the key levers for a sustainable future, we knew we must look beyond climate. This is why we have been working on a holistic sustainability strategy for the whole Viessmann Group. We did so using one of the most robust, science-based tools: the Future-Fit Business Benchmark. Future-Fit Business Benchmark takes the Doughnut Model and the Sustainable Development Goals and breaks them down into concrete indicators for a company. As a result a clear, long term destination towards a social and environmental break-even point is provided. Reaching this break-even point will mean that any of our potential negative impacts associated with what we buy, what we sell, and what we do are eliminated and we will create only positive impacts on people and planet. With our sustainability strategy we set ourselves a first clear milestone on the path towards becoming fully sustainable - in other words - a Future-Fit business. We hope to inspire others with our sustainability strategy, which we published in our Sustainability Report.
