"In 2021, the exposure of European refineries to the highly volatile conditions of the natural gas supply chain resulted in a corresponding adjustment of fuel blends for self-consumption with limited impact on air emission indicators as well. Between 2015 and 2021, a general downward trend in key air emissions of sulphur dioxide-SO2, nitrogen oxides-NOX and PM10 particulate matter (kg of emissions per tn throughput) is shown, with PM emissions affected by the reduction in natural gas use for limited periods in 2021 (compared to the previous year). In particular, air emission indices registered a 39%, 21% and 8% decrease respectively in the last six years, 2015-2021, as shown in the following diagram"
