Energy and resources

At our branches, we consume electricity and heating energy, our business trips produce greenhouse gas emissions – we take responsibility for this. To protect the environment and conserve valuable resources, we are continuously optimising our workflows and processes.

Management approach

Conserving resources and cutting harmful greenhouse gas emissions

The protection of the environment and the climate is a key issue for ista. On the one hand, this is a logical consequence of our core business and is anchored in our corporate vision. On the other hand, the subject of environmental protection is playing an ever greater role in the public debate and external stakeholders’ expectations of companies’ engagement are increasing in this respect. The demands we place on ourselves are also rising. We therefore save heating energy, electricity, water, paper, fuel and production materials at our own branches.

Our environmental objectives chart the course ahead. The responsibility for achieving them lies with the ista Sustainability Council, which is the contact responsible for all subjects relating to sustainability and the implementation of suitable action. It reports directly to ista’s CEO. The Council has an environmental consultant responsible for ecological issues.

As part of environmental management, the ista Environmental Guidelines oblige the management, managers and employees to use resources sustainably and responsibly. They apply to the entire Group throughout the world. It is the duty of the managers to promote the environmental protection philosophy among their staff. In addition to compliance with environmental laws, the responsible use of energy and raw materials – particularly at the individual’s workplace – is prescribed in the Environmental Guidelines.

A new travel policy which is tailored to our objective of saving resources has applied to ista employees worldwide since May 2014. Alongside operational expediency and cost-effectiveness, ecological aspects must be continually reviewed and taken into account. In concrete terms, this means, for example, that train journeys are to be given preference over air travel. Moreover, before booking a trip, the employees are to examine whether communication using modern technologies, such as Internet telephony, can replace a meeting.

 

Performance

Energy consumption cut

In 2014, roughly 23,115 gigajoules of electricity were consumed at ista branches worldwide. This electricity was mainly used for running offices. In addition, electric heating is used at our branches in Thimister (Belgium) as well as in Oslo and Trondheim (Norway). The consumption of heating energy from gas, oil and district heat amounted to roughly 22,248 gigajoules in 2014. Gas accounted for the lion’s share (64%). The company car fleet consumed a total of some 88,394 gigajoules of fuel. Rented and private vehicles used for company purposes consumed a total of 2,490 gigajoules and 3,735 gigajoules respectively. The energy consumption for electricity, heating and fuel is 29.3 gigajoules per employee.

Compared with the previous year, we succeeded in reducing our energy consumption both at the German and international branches. The specific electricity consumption per employee fell from 5.12 gigajoules in 2013 to 4.84 gigajoules in the reporting year. The consumption of heating energy also developed positively in the reporting year: in Germany, we managed to cut the consumption of heating energy per employee by 22% compared with the previous year to 6.84 gigajoules in 2014. Even allowing for the mild weather, our heating energy consumption still fell by 0.92 gigajoules.

We reduced our fuel consumption worldwide in all three vehicle categories – company car fleet, rented vehicles and private vehicles. In total, we saved 1,800 gigajoules compared with 2013.

 Avoiding emissions

The direct and indirect CO2 emissions – caused by heating energy and electricity consumption as well as business trips and paper consumption – amounted to 15,636 tonnes in 2014. With 7,742 tonnes, the company car fleet accounted for almost half of the emissions, followed in second place by air travel with about 2,799 tonnes. The consumption of gas and heating oil caused direct CO2 emissions of some 889 tonnes in 2014. District heat and cold led to indirect CO2 emissions of about 640 tonnes. All in all, we saved 666 tonnes of CO2 in the categories heating energy, electricity, transport and paper compared with 2013.

Eco-friendly travel

In the reporting period, ista’s employees worldwide covered a total of some 51 million kilometres, 79% of which in cars. In Germany, we reduced the upper limits for vehicle CO2 emissions in the individual company car groups in the reporting period. They apply as purchase criteria for diesel vehicles which are being newly leased. To record the consumption figures, we conducted our own measurements and surveys and did not rely on the manufacturers’ information. According to our calculations, the average consumption of ista Germany’s vehicle fleet amounted to 6.6 litres per 100 km in 2014 (compared with 6.78 litres per 100 km in 2013). Given a distance travelled of 12.9 million kilometres, this is equivalent to savings of 23,220 litres of diesel and therefore 73 tonnes of CO2 equivalent.

Compared with 2013, the average CO2 emissions of the company car fleet were therefore reduced by 5.7 g per km. Thanks to the new CO2 upper limits, our entire fleet will be low in emissions and consumption by 2018. Furthermore, we regularly informed company car drivers about their consumption in order to sensitise them to an environmentally friendly driving style.

In the reporting period, one new hybrid and one new electric vehicle were purchased in Norway. In Belgium, 13 new hybrid vehicles were bought, increasing the total number of hybrid vehicles in use to 17. Moreover, a fuel-saving competition for technicians is regularly held in Belgium. In the UK, employees who ride to work on a bicycle receive financial perks.

Long-distance business trips using Deutsche Bahn are CO2-neutral for ista as a corporate customer. Deutsche Bahn certifies to corporate customers that long-distance train travel has no CO2 impact as DB itself generates or purchases green electricity. That was the main reason for the sharp decline in CO2 emissions caused by rail travel although the number of kilometres travelled is roughly the same.  For short-distance journeys, it is assumed that they are either not counted as business trips since they are travel to work or they are, for example, trips to the airport which are already included in Atmosfair’s calculation of flight distances.

Our core business requires trips to customers by car. Thanks to digital remote meter reading, we can already reduce but not avoid these journeys entirely. This trend will continue. In Germany, independent service partners are responsible for the installation and reading of metering devices.

Paper saved

In 2014, ista’s paper consumption worldwide totalled roughly 467 tonnes. Of this, printing and copying paper accounted for 137 tonnes and production paper for 240 tonnes. Including notepads, envelopes and marketing materials, the share of recycled paper amounted to 62 tonnes. Compared with the previous year, paper consumption fell by 12.5% in absolute terms and the share of recycled paper was increased from 9% to 13%.

Various measures at ista’s branches worldwide are geared to cutting paper consumption. For example, ista Netherlands has set itself the target of reducing the number of printouts by 50%. At ista Spain, electronic billing is to be promoted even more and at ista Norway 90% of the bills are already dispatched electronically. ista Turkey does without printouts completely: faxes are forwarded as e-mails. At ista’s headquarters in Essen, we were able to save 42% of resources through centrally controlled, double-sided printing, i.e. we printed 55.5 million pages on 32 million sheets of paper. That corresponds to a saving of more than 100 tonnes of paper.

In addition, we have acquired CO2 certificates for some of our printed products produced at printing works, therefore making them climate-neutral. In the reporting period, the volume totalled 144 tonnes of CO2, which ista used to offset printed products and one event.

In 2015, we are changing over our bills in Germany, Luxembourg and Switzerland to certified recycled paper identified by the Blue Angel label. 2.5 times less water and energy is required to recycle waste paper than for the production of virgin fibre paper and no timber has to be harvested.

Water resources conserved

ista withdraws water almost exclusively from the public drinking water supply. The consumption figures are based on an estimated extrapolation. According to this, the volume of water withdrawn in 2014 amounted to 43,487 m3, including 422 m3 of well water. We at ista use water exclusively for sanitary purposes and as drinking water.
