Data Management

This section sets out the organizational boundaries and associated methodology for data collection and management.

Organizational Boundaries

For all of our material aspects identified in G4 guidance, the related data and performance information presented in this report cover ERM's operations as a group. Data reported are for those entities controlled by ERM Worldwide Limited (EWL) which is based in London, U.K.

ERM Certification and Verification Services

ERM CVS is a wholly owned subsidiary of EWL. 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. For more details of these services, visit www.ermcvs.com

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, Ethics and Policies, Environment, Community and Thought Leadership (memberships). Because ERM and ERM CVS have combined HR systems and office premises, the data in this report includes 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.

Data Methodologies

No significant changes were made to data-collection methodologies in FY14. Our 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.

Sustainability Focal Points at ERM offices around the world coordinate the collection of the majority of our environmental. 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). 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.

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 FY14, leased or owned office locations that were registered as encompassing less 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 is included in the office responsible for booking travel.

Data for new offices or offices acquired during the reporting period are included where available from the date of opening or acquisition, with exceptions noted where relevant.

Reference used for Total Recordable Incident Rate industry average

Industry average Total Recordable Incident Rate (TRIR) values are sourced from the annual US Bureau of Labor Statistics (BLS). During the FY14 reporting period ERM updated its reference TRIR from 1.2 (2009 average TRIR for North American Industry Classification System (NAICS) Code 54162, Environmental Consulting Services) to 0.60 (2012 average TRIR for NAICS Code 5416, Management, Scientific, and Technical Consulting Services). The NAICS code 5416 was used as no TRIR was published for the lower-tier code 54162 in 2012, the most recent year published.
