About this report

Our 13th Sustainability Report explains our approach to social, ethical and environmental issues and our performance during 2014.

Data

Data is for the calendar year 2014 and covers 124,000 direct employees. Data covers all subsidiaries of the Group. A subsidiary is an entity which we control and/or have a majority shareholding. Associates and joint ventures, where the Group may have influence or joint control, but not outright control, are not included. Data in our financial reporting will include associate companies not covered in our Sustainability Report.

Data is collected quarterly through our financial reporting system. Case studies and examples from our companies are collected via an annual survey. Each WPP company has nominated a sustainability representative to compile this, and surveys are signed off by the company CEO before submission to WPP.

The carbon footprint and employment data has been externally assured by Bureau Veritas. Our per employee carbon footprint figures are calculated using data for full-time equivalent employees (FTEs).

The content of this Report is prepared in accordance with the core option of the Global Reporting Initiative’s (GRI) G4 guidelines. See our GRI Index for a list of disclosures and their location in our report.
