CHAPTER 5 Our responsible management in 2018 Environment
It is notable that 6.4% of the electrici- ty we buy is generated using renewable sources.
In addition to the emissions derived from internal energy consumption, we calcu- late the external energy consumption through the emissions of scope 3. These emissions are converted to the equiva- lent consumption unit of natural gas,
according to the category, and the con- version and emissions factors published in the DEFRA (Department for Environ- ment, Food and Rural Affairs) JRC WTW Report and Renewable Energy Directive 2009/28. These categories are reported in 2018 although at the date of this re- port, they have still not been certified un- der the scope of ISO 14064.
As we do to control our emissions, we use an energy indicator based on the volume of activity of each business unit to meas- ure our performance with regards to en-
ergy consumption given the operations carried out each reporting year and the level of activity of each operation:
2 Those domestic or foreign companies over which we do not have 100% financial or operational control are excluded.

1 Scope includes the Gibraltar San Roque, La Rábida and Tenerife refineries. 2 Scope includes Spanish and foreign chemical plants, including the consumption of Indonesia plant. 3 Scope includes the assets with operational control and fields in Algeria, considered as per their working interest and reported because they are assets under control.
4 Scope includes Spanish co-generation plants and the combined cycle plant. Figures for 2016 and 2017 have been recalculated to standardize the units in which this index is expressed in 2018: TJ/TJ output of electrici- ty+ steam.
