Climate change

Aware of the climate change impact on a global scale, we undertake and plan a whole range of projects and activities relating to the reduction of greenhouse gas emissions, increase of energy efficiency, production of fuel with bio-components from renewable sources.

In October 2014, European Council agreed on the challenging 2030 framework for climate and energy, including a binding domestic target for reducing greenhouse gas (GHG) emissions of at least 40% in 2030 as compared to 1990. To meet this target, the European Council agreed that the emissions in the EU Emission Trading System should be reduced, compared to 2005, by 43%.
Four INA, d.d. installations are a part of the third phase of European Union Emissions Trading System (EU ETS): Rijeka Refinery, Sisak Refinery, Gas Processing Facilities Molve and Fractionation Facilities Ivanić Grad.

To reduce CO2 emissions into the air, the EOR - Project of CO2 injection into deep wells will contribute and, by reconstruction of gas stations, emissions of non-methane volatile organic compounds will be reduced or completely eliminated.

One of the goals of INA Group is the establishment of a comprehensive system of measurement / calculation and reduction of volatile organic compound emissions through the application of the LDAR methodology ((leak detection of volatile organic compounds and remediation of releases). We also monitor direct and indirect energy consumption, so that we can monitor the effectiveness of the taken measures / activities.

In 2014 INA, d.d. continued with the investments in biofuels-bioethanol blending projects in INA’s refineries. To fulfil the national target in 2014, INA, d.d. blended biodiesel (FAME – Fatty Acids Methyl Esters), certificated according to ISCC (International Sustainability and Carbon Certification). ISCC is one of the leading certification systems for sustainability and greenhouse gas emissions, and the European Commission recognized it as one of the first certification schemes to demonstrate compliance with the EU Renewable Energy Directive’s (RED) requirements.

Direct greenhouse gas emissions are monitored and also the CO2 emissions generated by road and air traffic, and are related to business trips of our workforce. INA Group does not use materials containing substances that deplete the ozone layer.

INA Group CO2 emissions (in thousand tons)


To ensure compliance with a new Act on Energy Efficiency, large companies are obliged to draw up an energy audit for big companies every four years (in accordance with the rules for conducting energy audit of large companies) or the company needs to implement energy management system (ISO 5001). In 2014 INA Group began certification in accordance with Energy management system ISO 50001 and in this way contribute to the savings by applying energy efficiency measures in order to achieve the EU objective of increasing energy efficiency by 20% until 2020.

The projects and activities to reduce greenhouse gas emissions and increase energy efficiency

• CO2 EOR Ivanić and Žutica: Project’s primary goal is to increase oil recovery residual oil on mature oil fields Ivanić and Žutica. Secondary target is to significantly reduce CO2 emissions, extending both fields life cycle and enforce further development of this region and local community. Trial exploitation of hydrocarbons and CO2 injection into 12 production wells near Ivanić Grad started in October 2014.

• To increase energy efficiency and savings, Rijeka Refinery had four key activities in 2014 which are a part of Energy Road Map: network maintenance, condensation recovery implemented on group of facilities (GP5), controlling the condensation mode in turbo generators and combined electricity production and purchasing. Realization of planned savings value was 70% for 2014.  Beside Energy Road Map measures, one of the conducted projects was Energy Efficiency improvement of process units. CO2 intensity in Rijeka Refinery has decreased compared to 2013.

• In Exploration & Production several projects aimed at improving energy efficiency and reduce greenhouse gas emissions are in progress. Optimization Project of the Fractionation Facilities Ivanić Grad is completed. Primary goal of Optimization Project is to assure production continuance with new electrical compressor for gas cooling, what increases efficiency of the turboelectric aggregates as well as the total yield of the gas plant. Beside energy efficiency, the optimization project decreases GHG emissions. Reconstruction of the Fractionation Facilities Ivanić Grad Waste Heat Recovery Units is in progress. Aim of the project is to significantly increase efficiency of Fractionation Facilities Ivanić Grad operation through cogeneration effect. In 2014, as a result of optimization projects at Gola, Kalinovac and Molve fields, E&P managed to reduce gas consumption in Northern Croatia Production Region. with these projects continuous reduction of the intensity of emissions in exploration and production of oil and gas is achieved (production is constantly increasing, and reduce emissions continuously).

•  ‘‘Green’ petrol station - Project of first ‘green’ petrol station construction is in the process of obtaining the necessary permits for petrol station Stupnik-istok. In the Split region tender was launched for a new ‘green’ petrol station.

• Due to the work organisation and maintenance of existing equipment in INA Maziva in 2014, steam consumption was reduced for 30% and consequently CO2 emissions were decreased for 31%.

Energy-saving projects in Information services

• Server virtualization enables company to use fewer servers, thus decreasing electricity consumption and waste heat. INA has performed server virtualization and virtualization ratio target for 2014 was 65% of full scope of servers determined for virtualization and the target has been accomplished.

• INA Unified Communication System Efficiency Influenced by growing internationalization, business trip optimization initiatives and collaboration trends, videoconferencing was introduced and integrated communication services are enabled across different platforms. Unified communications (UC) is the integration of communication services such as instant messaging, presence information, IP/mobile telephony, video conferencing, data sharing, Interactive White Boards and call control. Unified communications system increases efficiency in daily work and provide savings in travel costs. Decreasing number of long distance business trips results in energy and cost savings, pollution decreasing as well as reducing possibility of traffic accidents
