Emissions management
2015 was the last year covered by the LOTOS Group’s Corporate Social Responsibility Strategy for 2012−2015. One of its objectives was to bring average annual carbon (CO2) emissions intensity ratio at the Grupa LOTOS refinery, expressed in kg CO2/CWT, below 90% of the 2011 levels in 2015.
29.8 kg CO2/CWT*
that low was the average carbon emissions intensity ratio at Grupa LOTOS installations, down 79% on 2011 The reduction was made possible by connecting the refinery to the gas grid in 2012 and use of natural gas as fuel in the CHP plant, and as feedstock for hydrogen generation, as well as a number of other upgrades and efficiency-promoting measures.

The 2015 CO2 emissions intensity ratio (per production unit, direct emissions only) was:
- at Grupa LOTOS: 29.8 kg CO2/CWT
- at LOTOS Petrobaltic: 0.261 tCO2/toe
- at LOTOS Asfalt: Gdańsk plant − 0.018 t CO2/t of the product, Jasło plant − 0.11 t CO2/t of the product (various processes run at the Gdańsk plant and the Jasło plant characterised with different emission levels)
- at Energobaltic: 0.06 tonnes/GJ
Falling oil prices and the resulting decrease in prices of finished goods had a bearing on the environmental impact of the Grupa LOTOS refinery in Gdańsk in 2015. In the new price environment, the unit cost of energy generated from the refinery’s finished goods turned out to be lower than the unit cost of energy from natural gas. This was an opportunity to reduce operating expenses and improve our competitive position.
The larger share of crude oil products, the so-called finished goods in the energy and feedstock mix at our Gdańsk refinery had a marked impact on sulfur dioxide (SO2) and particulate emissions from our installations. At one of the hydrogen generation units, we used LPG as feedstock on a temporary basis.. It is worth stressing that the quality of finished goods, and the amount of emissions into the air were within the permitted levels set out in the integrated permit.
