2021 INTEGRATED MANAGEMENT REPORT

Atmospheric emissions

To monitor and reduce non-GHG emissions (gases with no greenhouse effect potential) into the atmosphere, we have an action system based on the continuous control of these emissions at our main production facilities.

Thanks to monitoring, self-monitoring mechanisms and external measures implemented through a Collaborating Entity for Environ- mental Quality (ECCA), we have detailed knowledge of our main emissions, mainly NOx, SO2 and particulates.

In the organic chemical industry, we have improved combustion processes, fostering the use of cleaner technologies and implemen- ting abatement systems that have reduced emissions of VOCs, methanol, CO and NOx. .

MEASURES TO REDUCE NON-GHG EMISSIONS Electrification of Exploration and Production facilities in Algeria.

Leak Detection and Repair (LDAR) campaign to measure and control diffuse emissions at the San Roque Biodiesel Plant (Spain).

Implementation of variable frequency drives in cooling towers to reduce electricity consumption at the Palos Chemical Plant (Spain).

1 The continuous measurement method was used to obtain the data. 2 Since 2019, the Exploration and Production business has used AP-42, Fifth edition Compilation of Air Pollutant Emissions Factors for non-GHG emissions, unlike

previous years, which has led to changes in the data in relation to 2018 figures. 3 Recalculated, including cogeneration emissions from the Guadarranque Chemical Plant. 4 The Puente Mayorga Chemical Plant changes its calculation methodology and NO increases considerably.
