Our sustainability strategy

Greater transparency, less CO2 emissions

With our smart solutions we offer building owners and residents the necessary transparency to save energy responsibly and therefore make a contribution to climate protection. But we are also taking a critical look at our own behaviour and want to go one step further towards zero CO2 every year.

Clear goals on the way to zero CO2

We intend to reduce our emissions completely to net zero by 2030. That is an ambitious goal but we are convinced we will achieve it thanks to our clear roadmap. Our net-zero roadmap includes the following areas: We already recognised very early on that our fleet of vehicles is one of the crucial levers to achieving zero CO2. The goal is clear and, at the same time, ambitious: we want to switch our entire fleet to 100% electrically powered vehicles by 2028. We are also systematically expanding our EV charging infrastructure. More and more of our sites now obtain their power from renewable sources.
