Piping Profits

PWYP Norway can reveal that ten of the world’s most powerful oil, gas and mining companies own 6,038 subsidiaries and over a third of them are based in secrecy jurisdictions. The three Norwegian companies mapped own 55 subsidiaries, 20% of which are based in secrecy jurisdictions. On these pages you will find more information about this project, the detrimental effects of secrecy jurisdictions and how these can be tackled. The database is publicly available and can be explored here.

Due to lack of resources, it will not be continually updated, but nevertheless represents an excellent snapshot of extractive industries and their subsidiaries in 2011. The Piping Profits database includes information on the 13 case studies and their 6,093 subsidiaries, containing details of:

  • The Parent Company

  • The location in which the subsidiary is incorporated
  • The percentage of the subsidiary owned by the parent company
