In this report published in 2008, Transparency International (TI) evaluates 42 leading oil and gas companies on their current policies, management systems and performance in areas relevant to revenue transparency in their upstream operations. Revenue transparency in this report includes three areas of corporate action where disclosure can contribute to improved accountability in the management of extractive revenues: payments to host governments, operations and corporate anti-corruption programmes. The companies are evaluated in a total of 21 countries of operation. This report is a featured product of TI's Promoting Revenue Transparency Project and attempts to characterise current levels of company revenue transparency, to point to best practices, and to suggest areas for improvement.
The 2008 report was updated in 2011.
