Air emissions
In 2010, the total air emissions (excluding GHG) decreased significantly (by 9%) compared to 2009, if we take into account the same set of companies. If we include the air emission data of IES (IT) and INA, then air emissions practically doubled.

At Exploration and Production, the biggest area for operational improvement was at INA Upstream, where the IPO Project (assessment of INA d.d. HC production activities at Posavina and Slavonija) was launched in 2010. Last year we reduced the amount of flared and vented hydrocarbons, and also reduced internal gas consumption (feed gas, heating). We are continuously decreasing the quantity of flared gas, and our goal is to only flare and vent gas for technological and emergency reasons.
At Refining, we have focused on basic pollutant emission reductions. The Leakage Detection and Repair (LDAR) Programme at the Slovnaft Refinery for monitoring of volatile organic compounds (VOC) has been operating for several years, and we have now started a similar programme at the Danube Refinery as well. The aim is to have more reliable information on VOC emissions, creating the basis for a VOC reduction programme. Through the ongoing energy efficiency programme, we can reduce the air pollutant emissions from flared gas. In the future, we aim to continue our efforts to reduce air emissions.
There were two major projects in the Petchem Division. In order to meet the air emission standards within our operating permit, we increased the capacity and renovated the quench oil unloading station. The second project was the installation of fixed roofs on floating roof tanks. The aim was to reduce the evaporation of raw materials. Our continuous efforts at improving energy efficiency have also had an impact on reducing specific CO2 emissions.
Compared to the Refining or Petchem Divisions, the Logistics and Retail Divisions are not so significant in terms of air emissions, but we do not consider being of lower priority though. With the aim of VOC reduction in mind, we began reconstruction of the Vapor Recovery Unit (VRU) at the Komárom Logistics Depot, and initiated a programme to measure VOCs at the Korneuburg Depot. Moreover, an LDAR Programme has been launched.
