We adopt the best strategies and use the most modern technologies to reduce emissions of air pollutants for the protection of air quality.
We apply the best techniques and standards to reduce emissions and control the major atmospheric pollutants.
Among the main atmospheric pollutants associated with industrial activities are the nitrogen (NOx) and sulphur (SOx) oxides: the first derives from the typical features of the combustion process (oxygen and temperature), the second from sulphur oxidation in fossil fuels. In 2018, NOx emissions fell by 4.5% compared to 2017. In particular, in E&P, which accounts for over 78% of the Eni consolidated result, the parameter decreased both in absolute terms (more than -2,100 tonnes) and with reference to production. In the G&P sector, NOx emissions decreased overall (-5.9%) as a result of the reduced quantities of gas transported from Sergaz, as at EniPower emissions increased both in absolute terms and in terms of production, as a result of increased variability in the production trend compared to the previous year. The contribution of the R&M and Chemicals sector was stable (-0.8% compared to 2017). The upward trend in SOx emissions in 2018 was due solely to the E&P sector, where an update of the composition of the gas sent to the flare for the KPC (Kazakhstan) and Bouri (Libya) sites was carried out, resulting in an increase at both sites of the percentage of H2S in the stream. In the R&M and Chemical sectors, on the other hand, emissions decreased (-7.2% compared to 2017), with a reduction in the emission intensity of refineries.
NMVOC emissions, which increased overall, rose in the E&P sector (+14.9% compared to 2017) for the activities in Algeria and Nigeria due to a change in the composition of gas and were down 13.7% in the R&M and Chemical sectors due to operational improvements at some Versalis sites and to reductions at the Gela green refinery following plant upgrading activities. Overall, TSP emissions remained stable, more than 90% of which relate to the E&P sector.
