About this report


Under the heading "Progress − from metering to conscious action", we are providing our stakeholders with transparent information on the progress we made in 2014 with the pursuit of our strategy, the attainment of our objectives and the implementation of action.

We are presenting the sustainability report 2014 of ista International for the first time as an online report, supplemented by a printed short version which can also be downloaded as a PDF. Under the heading « Progress − from metering to conscious action », we are providing our stakeholders with transparent information on the progress we made in 2014 with the pursuit of our strategy, the attainment of our objectives and the implementation of action. This sustainability report also represents the progress report for the Global Compact of the United Nations.

Frame of reference G4-17, G4-23

The report includes 48 companies worldwide. This sustainability report is based on the key performance indicators of the 2014 calendar year. The companies ista USA and ista Bulgaria were sold in the reporting period and are not included in the key figures for 2014. However, this is not reflected in the development of the key figures for 2014 as ista grew both in terms of  building size and employees despite the sale of these two companies.

The data for these two companies were still included in the figures for 2013 and previous years. The CO2 emissions of these two countries totalled 733 t in 2013 and therefore 4.5% of all emissions.

Guidelines and report preparation

In our reporting, we comply with the internationally recognised guidelines of the Global Reporting Initiative (GRI). We are reporting for the first time in accordance with the new version GRI-G4 and satisfy the « in accordance » option. This report has also been verified by the Materiality Disclosure Service of the GRI.

In preparation for this report and to determine the report contents, we conducted a materiality analysis with external stakeholders and internal sustainability experts. We present this process and its results in the chapter « Determining material report topics« .

Key figures and audit

Whereas the key figures of the workforce structure in the chapter « Employees » were recorded as of December 31, 2014, the specific key environmental figures are based on the average full-time equivalent (FTE) for 2014. Selected employee key figures, for example, the number of training days per head, are also based on the FTE figures.

Selected environmental KPIs for the calendar year 2014 were the subject of an audit with limited assurance conducted by KPMG AG Wirtschaftsprüfungsgesellschaft. Audited key figures are identified in the chapter « Energy and Resources » by the symbol .

We professionalised the recording of the environmental key performance indicators in 2014 and so considerably fewer extrapolations had to be made. The proportion of the data based on estimates and extrapolations is 19% for electricity consumption, 55% for water consumption and 30% for heating energy consumption.

As the procedures for recording key company figures and HR figures as well as for billing energy consumption sometimes differ in the individual countries, the quality of the data on which this report is based also varies. While some figures are precisely recorded data, others are based on estimates and extrapolations. In order to steadily reduce the proportion of estimates, ista is installing its own meters at more and more rented branches. As a result, we can increasingly prepare our own ancillary cost bills without delay.

In countries where precise data are only available for some branches, we estimate the figures for the other branches on the basis of the FTE figures or the square metres. The global ista average is used as a calculation basis for countries without precise recorded data.

The key consumption data for 2013 include figures of locations with rents billed as a lump sum. The individual types of consumption – electricity, water and heating – have been extrapolated in these cases. In some cases, ista has now obtained more accurate data on the billing of key consumption figures from the period of the 2013 Sustainability Report which still had to be estimated at the time of reporting. The 2013 key figures were not subsequently adjusted as the difference to the original figure was less than 5%.

The CO2 emissions were calculated, for example, on the basis of the conversion factors of the IEA, the Bavarian State Office for the Environment and the Institute for Housing and Environment.
