Creating trust by honest reporting

Transparency is part of our company's DNA. As one of the world's leading energy service providers, it is therefore a matter of routine for us to report in an open and transparent way on our total engagement for greater energy efficiency in buildings, sustainability and responsibility.

Our ninth Sustainability Report appeared in 2019. Here we report on progress in the field of sustainability based on the "Communication on Progress" as part of ista's membership of the Global Compact.
