CHAPTER 5 Our responsible management in 2018 Environment
During 2018, the Refining business unit was able to slash our emissions inten- sity by 9% versus 2017. Translating this into an emissions ratio gives a theoreti- cal reduction of 204 thousand tonnes of processed crude oil equivalent. The de- crease was achieved by optimizing unit operations and energy efficiency projects,
which were included in the improvement objectives defined in our ISO 50001-cer- tified Energy Management System. The most important examples of these en- ergy efficiency projects are the replace- ment of electric motors for turbines and improvements to the heat exchange sys- tems in unit operations.
1 The 2016 and 2017 figures have been recalculated as per the scope reported in 2018, which excludes certain facilities, especially in the Exploration and Production business, over which we do not have operational control. Data for ASESA is also excluded from the scope of reporting because it is considered not to be operated or controlled by the company.
We are rolling out a number of energy ef- ficiency programmes in the Refining and Chemicals businesses to cut their ener- gy consumption. Our energy manage-
ment system is ISO 50001 certified and covers all our major production facilities in Spain.
