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 eighth Sustainability Report appeared in 2018. Here we report on progress in the field of sustainability based on the internationally recognised G4.0 Guidelines of the Global Reporting Initiative (GRI). The report is regarded as "Communication on Progress" as part of ista's membership of the Global Compact.
