Challenge The Data

The database relies on public sources which in most cases provide a good picture of contracts but in some cases may not be accurate or contain all the required information. In these cases, the Database reports the project data which seem to be the most accurate. When unable to obtain more information, projects are included with the limited information available. Some projects (particularly those involving local and small scale operators) tend to be omitted because they are usually not reported by the sources on which the PPI Projects Database relies.

If you possess more complete or accurate information than that published on the Web site and would like to contribute to improve the data, send us your comments and relevant information. The research team will review. Please read carefully the information on our Methodology page, which describes the type of projects included in the database.
