A significant subsidiary is any part of a larger organisation that in itself consumed more than 6000 MWh of half hourly electricity during 2008. In this circumstance, the significant subsidiary may be able to enter into the carbon reduction commitment scheme in isolation from the rest of its parent or group organisation.
By entering any significant subsidiaries into the carbon reduction scheme as an entity in their own right, the parent or group organisation may benefit by separating itself from the subsidiary and brands, marketing, financial or practical implications that would otherwise exist.
