Sustainability Report 2016

About this report

Supporting data

To measure our social, economic and environmental impacts and support programs for improving our sustainability performance, ERM collects and reports data relevant to our global operations. The data are grouped, where applicable, in alignment with the focus areas presented in this report.

Data that relate to specific GRI G4 indicators are labeled (e.g. ) throughout this section and the report.

More information on the location of specific GRI G4 and UN Global Compact content within this report can be found in our content indexes

Organizational boundaries

ERM follows GRI G4 guidance, including the identification of material aspects. All information in this report, including data and performance information presented, covers ERM's operations as a group. Data reported are for those entities controlled by ERM Worldwide Group Limited (EWGL), which is based in London, UK.

Data in this report are inclusive for ERM CVS. ERM CVS is a wholly owned subsidiary of EWGL. ERM CVS works with many of the world's leading multinational organizations and delivers independent, third-party, performance-driving certification, verification and report assurance services to help clients improve their sustainability performance.

ERM CVS operates under ERM's internal policies and practices, and the following sections of the Sustainability Report therefore apply also to ERM CVS unless indicated otherwise: people, health and safety, business conduct and ethics, environment, community and thought leadership. Because ERM and ERM CVS have combined human resource systems and office premises, the data in this report include the operations of ERM CVS.

Due to the nature of its work, ERM CVS has additional policies and procedures relating to independence and an Advisory Board that undertakes the role of the Committee for Safeguarding Impartiality.


Our ERM Sustainability Reporting Protocol guides the data-collection process. Where applicable, the protocol is based upon external guidance, including the GRI Guidelines and the World Resources Institute/WBCSD Greenhouse Gas Protocol.

The Sustainability Network across ERM offices around the world coordinates the collection of the majority of our environmental data. We expect to continue to improve the robustness and depth of our data over time.

We report environmental data for offices that fall within ERM's material threshold (as defined in our Sustainability Reporting Protocol) per fiscal year (FY), which runs 1 April to 31 March. ERM's Sustainability Reporting Protocol provides guidance for the development and maintenance of robust data collection systems that will measure sustainability performance across all key performance areas in a consistent, accurate and auditable manner.

We continue to improve our greenhouse gas data, including working with landlords to increase access to actual energy consumption data for leased offices. Where data are unavailable, we estimate consumption based on the amount of space we lease and expected energy intensity of office buildings. Prior to FY15, we used a generic standard for commercial office buildings. It was determined in FY15 that we have sufficient real data to calculate ERM intensity factors for leased office space and buildings. This is more representative of how ERM operates, as well as our office performance. Our FY14 results have been restated applying this methodology.

On a per-indicator basis, sources constituting less than one (1) percent of ERM's total impact for that performance indicator annually were excluded from the data collection and reporting process. Sources excluded are reviewed annually to determine if emissions are relevant for a continued de minimis exemption. For FY16, leased or owned office locations that were registered as encompassing fewer than 50 square meters, excluding dedicated server hosting spaces, were also considered de minimis and excluded from the data collection and reporting process. Impacts associated with office spaces of this size are projected to be less than one (1) percent of ERM's total impact in aggregate. Travel data for employees residing in these offices are included in the office responsible for booking travel.

For data normalized by the number of full-time equivalent (FTE) employees, we applied the average yearly FTE, which is more representative of FTEs throughout the year than the year-end FTE. Average yearly FTEs have been applied in sustainability reports since FY15.

All financial data are reported in US dollars, unless otherwise noted.

Data for new offices or offices added through ERM acquisitions during the reporting period are included where available from the date of opening or acquisition – subject to specific transition arrangements to ERM systems and processes. These arrangements are noted where relevant.

In some instances in the data below, rounding results in small discrepancies.
