Every year, the company defines environmental protection goals aimed at energy efficiency and reduction of energy consumption, guided by the defined Energy Policy and the Energy Management procedure. Modernization of telecommunications equipment, increasing use of IT resources, renovation of real estate and optimization of power supply and air conditioning systems are the main reasons for the reduction in energy consumption in 2019.
As part of the modernization of mobile network radio equipment, which we continued to implement intensively during 2019, the old equipment was replaced with new, significantly more energy efficient. We are proud that during 2019, 12 wind solar systems produced electricity to power mobile network base stations. We began consolidating data centers, during which the transition to a common infrastructure and the installation of high-processing server units will reduce the required space by 65 percent, with a significant increase in energy efficiency. With the aim of increasing the network's resilience to the impact of weather conditions and ensuring business continuity, financial resources are invested in regular operational activities in order to replace the above-ground network at specially exposed locations with an underground one. HT also implements appropriate technical and organizational measures to ensure stationary and mobile backup power supply systems for all important infrastructure facilities.
With its products and services, HT contributes to reducing electricity consumption and its users' resources. Cloud solutions enable users to develop and implement various forms of online business using a highly efficient shared IT infrastructure, reducing electricity consumption and CO₂ emissions without compromising security. With the development and wider offer of ICT cloud services, HT additionally contributes to the favorable impact of ICT technologies and services on climate change by reducing the need for travel, reducing the use of paper and other material resources, and more rational and efficient use of energy.
Combis, ASR Group, and FER completed the development of ComEnergy products, with EU co-financing. ComEnergy is an energy consumption monitoring platform consisting of advanced high-volume analytics and an application for monitoring energy consumption and environmental conditions. This solution enables precise monitoring of energy consumption, and connects various data sources, integrates and processes them, and provides insight into the actual consumption, ensures lower costs, optimizes consumption, and reduces risks and malfunctions.
RESPONSIBILITY TOWARDS ENVIRONMENT
Sustainable development and climate protection are strategic determinants of Hrvatski Telekom and DT Group. As the only telecommunications company in Croatia certified according to the ISO 14001 environmental management standard, HT focuses on the implementation of green technologies and energy-saving solutions that are beneficial to the society with reduced greenhouse gas emissions.
We have been procuring ‘green’ electricity obtained exclusively from renewable sources since 2016. In mobile networks, we also use renewable sources to power base stations. By investing in the latest technology, we raise energy efficiency, and by introducing the latest ICT technologies and services, we are reducing our own and carbon footprint of our customers. We continually encourage our employees to think and act ecologically, and many initiatives enable us to reduce energy consumption and adverse climate impact and to manage waste. HT constantly refurbishes and modernizes its fleet, enabling us to improve quality and efficiency and reduce environmental impacts.
Through the documented process Dealing with substances that affect the ozone layer, we monitor and manage activities with a possible impact on the atmosphere. Total greenhouse gas emissions in 2019 is 2 percent higher than the year before. Total direct carbon dioxide emissions from non-renewable sources increased by 0.8 percent, due to a reduction in the consumption of extra light fuel for heating. At the same time, there was an increase in the consumption of natural gas and diesel fuel for the fleet. Consumption of extra light fuel oil and diesel fuel for generator sets declined by 12 percent due to the sale of two facilities and less need to include generator sets in mobile networks. The significant decrease in total indirect carbon dioxide emissions from 2017 to 2019 is the result of the procurement of CO₂-neutral ZelEn electricity from HEP-Opskrba. Due to lower energy consumption over the years, the trend of NO₂ and SO₂ is generally declining. Regular boiler room maintenance is the basis for reducing emissions in the environment, and their automated regulation monitors the parameters of consumption and contributes to more efficient resource use and lower emissions into the environment.
Hrvatski Telekom focuses on a circular economy approach in key areas of its business related to the energy efficiency of its products and services, sustainable management of materials, reuse, and recycling. The aim is to minimize our own and customers’ negative impact on the climate and the environment. Whenever possible, we seek solutions for the sale of functional devices and equipment, to extend its lifespan. So far, HT has collected and ecologically disposed of over 152,000 old mobile devices, batteries, and related accessories. Almost all waste generated by HT's business processes is further processed through recycling, which enables the reuse of valuable components. Digitalization of internal processes and transition to e-business also constantly contribute to the reduction of paper consumption.
The amount of waste in industry depends on business activities. In 2019, the total amount of waste increased by 46 percent compared to the previous year, due to the modernization of infrastructure, disposal of old and non-functional equipment, and cleaning of many facilities and warehouses. The amount of electronic waste increased the most. Most waste is recycled, and a minimal proportion is disposed of through disposal procedures.
In our daily office operations, we implement the measures and rules of conduct of the Green Office. By digitalizing internal processes and e-business, we are constantly contributing to the reduction of paper consumption in offices. In 2019 it is lower by 6.3 percent. The sales department continuously digitizes sales documentation and processes, which also reduces paper consumption. When it comes to users, the number of e-invoices is constantly growing. Digital platforms such as Moj Telekom HR provide users with all the necessary information about the contract, services and invoices, and ensure easy and fast bill payment, which directs users from classic paper documents to digital documentation available always and everywhere.
HT does not use water for technological purposes and none of its business processes pose a risk of water flow pollution. Where there is a risk of oil spills into sewerage, technical means are used that ensure the separation of oil from the liquid. Water consumption control is a result of good employee environmental awareness, optimization of business premises, rapid repair of failures and preventive maintenance and reconstruction of heating/cooling systems and water supply networks. Water consumption increased compared to 2018 due to renting office space, and due to losses and leaks in dilapidated network installations, which have since been repaired.
