Essen, June 28, 2017. The international energy service provider, ista, managed to drastically cut its air kilometres travelled for business trips in Germany. Heat and electricity consumption were also appreciably reduced. This is shown by the key figures in the new sustainability report which the company is publishing today.

"Energy efficiency is our core competence," says Thomas Zinnöcker, ista's CEO. "And that also includes us taking an honest look every year to see whether we as a company managed to improve our key sustainability figures." ista again achieved success in the 2016 reporting year: 

The company always recommends its employees to use CO2-free train travel for trips within Germany. So the number of air kilometres travelled was reduced in Germany by 25% compared with the previous year. A total of 329 tonnes of CO2 equivalent was therefore avoided: the average per capita CO2 emissions of the German population are 11 tonnes.

Furthermore, heating energy consumption was cut by 22% throughout the company. The individual locations adopted different approaches to achieve this. For example, the "Energy Check Tool" helps the Dutch employees to save energy. The tool they developed themselves compares heating demand and consumption in an intelligent way and therefore permits efficient heating without heat losses.

ista also managed to reduce electricity consumption by a total of 12.9%. The crucial factor here was reading the consumption figures every month or at least every quarter. This made consumption more transparent for the employees and raised their awareness for "saving electricity". Savings of up to 24% were achieved in this way at some German branches.

ista collects its key sustainability figures in accordance with the internationally recognised guidelines of the Global Reporting Initiative (GRI) and the German Sustainability Code (DNK). The full sustainability report is available as a download here.
