Environmental protection

Systematic environmental management is an integral part of INA’s business policy, and all INA’s segments, which have actual or potential significant impact on the environment, have certified environmental management systems in accordance with ISO 14001 standard.

When creating INA Group health, safety and environment and social impact policy, special attention is paid to safe and healthy working conditions and care for the environment by applying the precautionary principle and rational management of resources, thus creating the foundation for the realization of the principle of sustainable development.

In INA d.d., “Health, Safety and Environment Management System in INA Group Companies” document is in effect, which is compliant with the HSE policy and social responsibility of INA Group as well as the Strategic objectives and HSE programs of INA Group and serves as a support to business in the implementation of an efficient management of all health, safety and environment aspects.

Environmental protection legislation

The requirements in terms of environmental protection and product quality are increasingly stringent, and Croatian legislation in the field of environmental protection currently includes approximately 130 legal documents (laws, regulations, decisions), of which a large part has an impact on the operations of the INA Group.
Therefore, exceptional attention is paid to compliance with valid legal regulations and standards, and we actively monitor and, if necessary, participate in the legislative process through work in professional organizations and cooperation with authorities.
The Industrial Emissions Directive aims at integrated prevention, reduction and control of pollutants in air, water, land and sea, the prevention or reduction of waste generation and the efficient use of raw materials and energy, and requires that the facility is regulated by environmental permits based on the application of best available techniques (BAT). Four of INA’s facilities are liable to obtaining environmental permits: Sisak Refinery, Rijeka Refinery, Gas Processing Facilities Molve and Fractionation Facilities Ivanić Grad.
The listed facilities have valid Decision on the Integrated Environmental Protection Requirements (environmental permit) based on the requirements of the relevant legislation and the Reference document on best available techniques for the refining of mineral oil and gas, which is a reference in determining the conditions in environmental permits.
Complying with legal requirements concerning environmental protection requires large investments. In Refining and marketing BD and Exploration and production BD a whole series of projects is underway, aimed at aligning with the best available techniques for reducing emissions of pollutants into the air, water and soil.


One of the main challenges facing the refining industry is to ensure growth and at the same time limit greenhouse gas emissions. Aware of the impact of climate change on a global level we are undertaking and planning a number of projects and activities to reduce greenhouse gas emissions and increase energy efficiency.

EU ETS (European Union Emissions Trading System)
INA is continuously improving the monitoring and reporting of greenhouse gas emissions. In order to ensure emissions trading system compliance with the legislation, effective use of allocated free allowances, the transparency of the system of planning, monitoring and reporting, and transparency of emission trading and accounting activities, internal document Regulation on greenhouse gas and emission allowances management in INA, d.d. was published.
All four of INA’s ETS facilities have valid permits for greenhouse gas emissions. Carbon dioxide emissions are monitored in accordance with the approved plan for monitoring greenhouse gas emissions, and the annual emissions are verified by an accredited verifier and reported to the authorities in legally defined deadlines.


Air emissions from the installations with the biggest potential impact on the environment are regulated by environmental permits that provide emission limit values and the requirements for monitoring of emissions. Measurements of air emissions are carried out regularly by licensed companies, and the air quality around the refinery is continuously monitored on immission stations. In R&M BD and E&P BD a series of projects is underway aimed at aligning with the best available techniques for reducing emissions of air pollutants, such as improving the efficiency of process furnaces, boilers modernization of the power plant, the installation units for recovery of gas from the flare system, tanks improvement, modernization filling stations / unloading stations and others.


During production and processing of oil and gas, different types of waste are generated, so INA published Waste Management Strategy 2015-2018 with aim to reduce its emergence and increase the proportion of recycled waste. Strategy defines activities for waste management improvement honoring the principles and order of priority of waste management, as well as other statutory obligations. INA complies with the highest standards and best industry practices in the field of environmental protection and is directed towards further development of the waste management system. 


Technological and energy processes use significant amounts of water, which is pumped from Sava and Kupa rivers, the storage system Tribalj, own wells, sea and water supply systems. Facilities discharge industrial, cooling, rainwater and sanitary waters which are treated before discharge with physical, physic-chemical or physical – chemical – biological processes, depending on the type and degree of contamination. The quality of incoming and outgoing water at waste water treatment plants is continuously monitored, with the aim of achieving the conditions set by environmental and water right permit.


Preserving biodiversity is one of our core values. For every new procedure that requires an environmental impact assessment, an Environmental impact study is made, which describes all aspects of the environment and possible impacts on the environment as well as on the bioecological characteristics and all environmental protection measures are prescribed. During 2015, we created a database of all sites in order to identify those that are located in sensitive areas of biodiversity (geographically and legally defined area which is protected in order to preserve the biological and landscape diversity, including NATURA 2000), culturally sensitive area (place which is protected for their cultural or recreational value) and water-sensitive area (the area from the list of the Ramsar Convention and dry areas). In E&P BD three sites were identified as sensitive areas of biodiversity and water, and biodiversity action plans were made for exploitation fields Kalinovac, Stružec and Gola.
