pg. 59 b) In terms of greenhouse gases, the inventory comprises the emissions of CO2

(carbon dioxide), CH4 (methane) and N2

O (nitrous oxide). e) The inventory of atmospheric emissions is elaborated according to the orientations of the GHG Protocol – a Corporate Standard (WRI/WBCSD). Its scope

includes assets which we operate and those in which we hold 50% or more financial control. The inventory’s approach follows the bottom-up methodology, i.e.,

the total inventory is the sum of the emissions of the each source emission.
