Sustainability is nothing new. In the 17th century, water and forestry management were oriented towards it. With the Brundtland Report in 1987, the SDGs of the United Nations in 2015, the Paris Climate Agreement in 2016, to name just a few global initiatives, sustainability goals are receiving more and more attention on an international level. European legislators with the Supply Chain Act, corporate managers, investors, and ultimately end consumers are also focusing on sustainability benchmarks in their actions.

With the global effects of our industrial, technical and financial economic activities, social and ecological circumstances have fundamentally changed, which is currently particularly evident in the climate crisis.

How a company positions itself in its sustainability context the company must formulate and implement by itself. The sustainability strategy must be defined by situational and operationalized business terms.
