Introduction and objectives of work
Bureau Veritas UK Limited (Bureau Veritas) has been engaged by WPP plc (WPP) to provide limited assurance of selected sustainability data for 2017. This Assurance Statement applies to the related information included within the scope of work described below.
Scope of verification
The scope of our work was limited to assurance over the accuracy of the sustainability data
listed below and included in WPP’s Annual Report (the ‘Report’). Our work includes all global
operations under WPP’s control for the period of January 1, 2017 to December 31, 2017 for
the following indicators (‘Selected Information’):
GHG Emissions & Associated Activity Data
-
Scope 1 and Scope 2 emissions from WPP’s global operations
-
Scope 3 emissions from business air travel
Employment Data
-
Age and Gender data
-
Ethnicity data (UK and USA operations only)
Health and Safety data
-
Days Lost to Sickness
-
Work-Related Injuries
-
Work-Related Deaths
Waste Management Data
-
Waste to Recycling
-
Non-Recycled Waste
Limitations and Exclusions
Excluded from the scope of our work is any verification of information relating to:
-
activities outside the defined reporting period;
-
other information included in the Report other than scope defined above; and
-
Other scope 3 emissions including emissions from leased cars, taxis and couriers.
These have been estimated as an additional 15% of WPP total GHG emissions
figure, added to the carbon footprint and reported as ‘other estimated scope 3
emissions’.
This limited assurance engagement relies on a risk based selected sample of sustainability data and the associated limitations that this entails. This independent statement should not be relied upon to detect all errors, omissions or misstatements that may exist.
Responsibilities
The preparation and presentation of the Selected Information in the Report is the sole responsibility of the management of WPP.
Bureau Veritas was not involved in the drafting of the Report. Our responsibilities were to:
- obtain limited assurance about whether the Selected Information has been
appropriately and accurately prepared;
- form an independent conclusion based on the assurance procedures performed and
evidence obtained; and
- report our conclusions to the Directors of WPP.
Assessment Standard
We performed our work in accordance with a comprehensive internal protocol that guides our
verification activities. Our methodology is based on international best practice and
incorporates the requirements of the most widely used assurance international standards
including AA1000 Assurance Standard, ISAE3000, and ISO14064-3. Our conclusions are for
‘limited’ assurance as set out in ISAE 3000.
As part of the independent verification, Bureau Veritas undertook:
- interviews with relevant personnel of WPP responsible for GHG emissions
accounting, waste data and employment data;
- a review of WPP information systems and methodology for data collection,
aggregation, and analysis;
- a review of information and calculations used to determine GHG emissions;
- a remote review of a sample of the Selected Information against the corresponding
source documentation from 9 of WPP’s operations worldwide. The operations were
selected on a risk basis, taking into account energy consumption, geographical
location and head count.
- one of WPP’s operations was removed from an initial sample of 10
operations due to the unavailability of personnel to provide supporting
evidence. In addition, the energy consumption from one operation was
eventually removed from our sample due to the site being unable to provide
supporting evidence within the deadline for verification;
- audit visits to five additional WPP operations: GTB USA, Dearborn; WPP 2005
Limited, London; MediaCom Australia Zenith/TCG, Sydney; MRB India, Mumbai;
AKQA, London; and
- a review of the consolidated 2017 data to check end of year accounting and reliable
transposition.
Conclusion
Based on the verification conducted by Bureau Veritas, there is no evidence to suggest that
the GHG emissions assertions shown below, and the age, gender, ethnicity, health and safety
and waste KPIs as stated by WPP in its 2017 Annual Report:
- are not prepared in accordance with WPP’s relevant internal methodologies; and
- are not materially correct and a fair representation of the GHG emissions, waste and
employment data for WPP.
