About this report


In the CR Report 2015, we inform our stakeholders on the INSIDEista platform about progress made with our strategy, our objectives and the implementation of action in the 2015 reporting year.

CR Report 2015

The CR Report 2015 of ista International is ista’s sixth sustainability report – this year, we are presenting it for the second time as an online report on the INSIDEista platform. This sustainability report also represents the progress report for the Global Compact of the United Nations.

Frame of reference G4-17

The report includes 48 companies worldwide and is based on the key figures for the 2015 calendar year.

Guidelines and report preparation

In our reporting, we comply with the internationally recognised guidelines of the Global Reporting Initiative (GRI). We report in accordance with the latest version GRI G4 and satisfy the « in-accordance » option. This report has also been verified by the Materiality Disclosure Service of the GRI. The correct positioning of the G4 materiality disclosures (G4-17-G4-27) has been confirmed by the GRI.

In preparation for last year’s report and to determine the report contents, we conducted a materiality analysis with external stakeholders and internal sustainability experts. We validated the results of the analysis during preparation of this CR Report. We present the process and results in the chapter Focus on the essentials.

Key figures and audit

Whereas the key figures regarding the workforce structure in the chapter Employees were recorded as of December 31, 2015, the specific key environmental figures are based on the average full-time equivalent (FTE) for 2015. Selected employee key figures, for example, the number of training days per head, are also based on the FTE figures. Furthermore, there are differences in the headcount figures between the consolidated financial statements and this sustainability report. This is due to a different definition of headcount. For example, whereas temporary student workers have been included in the data for this sustainability report, they were not included in the consolidated financial statements.

Selected key environmental figures for financial year 2015 were the subject of an audit with limited assurance conducted by KPMG AG Wirtschaftsprüfungsgesellschaft. Audited key figures are identified in the chapter Environment by the symbol .

We are making every effort to further professionalise the recording of the key environmental figures. Consequently, estimates and extrapolations are more accurate this year as we can, in most cases, count on reliable figures from the countries and there were only a few branches for which figures were not yet available on the publication date of this report. The proportion of data based on estimates and extrapolations is 22% for electricity consumption, 60% for water consumption and 37% for heating energy consumption.

CO2 emissions, for example, were calculated on the basis of the conversion factors of the International Energy Agency, the Bavarian State Office of the Environment (Bayerisches Landesamt für Umwelt) and the Institute for Housing and the Environment (IWU). When balancing CO2 equivalents, we converted the other greenhouse gases emitted (e.g. carbon dioxide or methane) into CO2 emissions in line with their impact on the climate and then stated them, together with the CO2 emissions, as CO2 equivalents.

Editorial note

The copy deadline for this report was May 30, 2016.
To improve readability, we have avoided using both genders and only use the masculine form. However, the feminine form is also meant. The sustainability report of ista International appears annually. The next report will probably be published in the summer of 2017.
