* Historical 2020-2017 data were calculated following the methodology of the SASB Oil&Gas Standard indicator. The methodology applies default values to the characterisation of crude oil and natural gas, as hydrocarbons included in these proved reserves (1P).

* This indicator shows the total primary and final energy consumption, being higher than the operational energy consumption reflected in other indicators, as for these latest, the primary energy consumed in G&P is reflected in the steam consumers, excluding the sold energy to third parties. The variation in energy consumed in 2021 compared to 2019 is explained by:

E&P: the Thailand and Malaysia assets were eliminated and production at the remaining wells is falling, so the overall activity has declined. Refining and Gas&Power: although the crude oil processing activity recovered in 2021, it was slightly below 2019 and therefore energy consumption fell. Chemicals: total energy consumed rose slightly; in the CQPM activity, this was due to the increase in LAB production and in output, which also increased

the activity of Planta Química Palos, CCB and Deten.
