Cepsa works to avoid and if this is not possible, reduce our non-GHG emissions (primarily SO2, NOx and particulates) to minimize the damage caused by these substances to the environment and hu- man health. To achieve this, we have a procedure in place to continuously con- trol these emissions, and can report that indicators measuring these emissions by production unit have been decreasing year-on-year thanks to the combustion enhancements we have made and the use of cleaner technologies and abate- ment systems. In the same vein and as

part of our continuous improvements drive, a raft of investments are planned for the coming years, such as: work to boost efficiency and use natural gas as a fuel in certain ovens; installing scrubbers for gas that may be used as fuels; and en- hancements to the steam recovery units at some of our facilities. Despite these ef- forts, NOx emissions are up year-on-year in the Chemicals business, due to the In- donesia plant that was not operating dur- ing most of 2017.
