Energy and environmental bookkeeping

We are monitoring energy efficiency in more detail and more systematically since the introduction of the system for the targeted monitoring of energy consumption at Telekom Slovenije in 2014. The system will be further upgraded. For several consecutive years, the Group has ensured comparability in terms of energy consumption in the scope of international energy and environmental benchmarking organised by the European Telecommunications Network Operators’ Association (ETNO). Benchmarking is carried out by calculating energy consumption in kilograms of CO2 equivalent (carbon footprint). Telekom Slovenije’s carbon footprint (Scope 1 and 2 only) was estimated to be slightly less than 50,000 tonnes in 2014, while that of the Telekom Slovenije Group was estimated at 70,000 tonnes.

The majority of emissions are generated by electricity, as Slovenia has one of the largest carbon footprints in Europe, with more than a half a kilogram of CO2eq per kWh of electricity supplied.

In addition to energy, the comparable data include certain other environmental aspects such as the use of paper. Telekom Slovenije recorded a small reduction in consumption (of one tenth) relative to 2013.


Prior to the launch of the ISO 50001 project, energy and environmental costs totalled nearly EUR 20 million at the Telekom Slovenije Group and EUR 14 million at the parent company. Those costs were down by nearly EUR 3 million in 2014. Two thirds of the aforementioned costs are accounted for by the cost of electricity. Production by own solar power plants accounted for 0.24% of total electricity consumption.

Sum of electricity costs, fuel for the car fleet, heating fuel, and remediation and municipal services linked to Telekom Slovenije’s integrated energy and environmental management system.

The Group used 2% less electricity relative to 2013, resulting in a 13% decrease in associated costs. The reduction was partly the result of extreme weather conditions, as two thirds of months were either the warmest (during the winter) or coldest (during the summer) in the six years since Telekom Slovenije has systematically striven for efficient energy consumption.

Fuel for the car fleet and heating94

The average number of vehicles at Telekom Slovenije was reduced by 1% in 2014. The number of work-related kilometres travelled was up 2% and the consumption of motor fuels up 4% relative to 2013 due to an increase in the scope of field sales and the elimination of the effects of extraordinary environmental conditions at the beginning of the year (ice storm). Vehicle fuel costs were down 2% due to lower prices of refined petroleum products during the second half of the year.

Telekom Slovenije is implementing additional initiatives to reduce environmental impacts and fuel costs. Employees are transported between locations in Ljubljana by minibus, while employees took the initiative to car-pool on the Ljubljana-Celje-Maribor route. Heating costs were down 19% relative to 2013 due to the previously mentioned weather conditions and declining fuel prices.

Waste management95

Given the nature of its activities, Telekom Slovenije is not a major polluter in Slovenia or the other counties in which it is present. In terms of quantity, we generated the most construction waste in Slovenia. The latter totalled 1,072 tonnes in 2014. We forwarded more than 429 tonnes of separated waste (excluding construction and mixed municipal waste) compared with 454 tonnes in 2013. Hazardous waste totalled 33 tonnes compared with 67 tonnes in 2013. The overall quantity was down due to a sharp decrease in the quantity of lead batteries, which previously accounted for more than two thirds of Telekom Slovenije’s hazardous waste.

The quality of municipal waste monitoring across Slovenia varies widely, as the reports of different companies are in various units (e.g. kg, m3, m2 and population units). The difference in monitoring is even more evident on the other markets of South-Eastern Europe, where environmental management standards are still looser than in Western Europe and Slovenia. The estimated annual volume of municipal waste generated by Telekom Slovenije is around 200 tonnes, and nearly 600 tonnes according to the formula prescribed by the Slovenian Environment Agency (ARSO) and the Statistical Office of the Republic of Slovenia (SORS): 1m3 = 1,000 l = 177 kg.

Electromagnetic radiation96

A total of 224 additional comprehensive measurements of environmental impacts due to the expansion of the fourth generation mobile network were carried out. The level of radiation has increased slightly at base stations where we are introducing LTE technology. However, the base stations remain environmentally acceptable and within the limits established by Slovenian law, which in some respects is even stricter than European law. All reports regarding the measurement of electromagnetic radiation were turned over to the ARSO, where the latest data regarding environmental impacts is stored and accessible for review by all citizens.

Group companies outside of Slovenia also measure environmental impacts in accordance with local legislation.
