Exploration and Production (tonnes of CO2 equivalent/ tonnes of oil & gas) 0.17 0.13 0.14

Refining (tonnes of CO2 equivalent/tonnes of crude oil processed) 0.17 0.18 0.18

Petrochemicals (tonnes of CO2 equivalent/tonnes of chemicals produced) 0.37 0.36 0.36

Gas & Power 1 (tonnes of CO2 equivalent/TJ output of electricity + steam) 72.19 74.78 75.68

We also measure the volume of GHG emissions according to the level of activ- ity of the emitting facilities, which we re- fer to as emissions intensity. Due to the wide diversity our industrial operations, emissions intensity is calculated using

the different variables that are character- istic of each business. Based on our Car- bon Strategy, we are working to devise a Global Carbon Index for all businesses per unit of energy.

1 Gas & Power emissions intensity figures for 2016 and 2017 have been recalculated to standardize the units in which this index is expressed in 2018: tonnes of CO2 equivalent/TJ output of electricity+ steam.
