Reporting and Data

Reporting Approach

We see sustainability as integral to how we operate. Our Corporate Responsibility report and this website summarise key data on Grainger’s impacts and activities over the last year.

Our 2009/10 online sustainability report enables different stakeholders to easily access relevant information and drill down from high-level strategy to detailed performance statistics. In addition, we provide a summary of our sustainability performance in Grainger’s annual report 2010.

Data Qualification Note

• Restatements/changes: Explanation of the effect of any re-statements of information provided in earlier reports and the reasons for such re-statement (e.g., mergers/acquisitions, change of base years/periods, nature of business, measurement methods)
• e.g.:Carbon office emissions are restated downwards due to an incorrect meter reading at Knightsbridge last year

• Measurement information: Notes to quantitative performance values, indicating how data has been measured and calculated (e.g., metre readings, on line data gathering systems, calculations by outsourced data analysts, etc.), and whether estimates have been made and how.
• See examples below:

i All our offices are in multi-tenanted buildings so we are unlikely to ever be able to access data on central plant emissions from our offices.

ii The 2008/9 office carbon emissions are restated and reduced by 75 tonnes due to a corrected meter reading and subtraction of a central plant building meter that covers other tenants’ energy consumption as well as that of Grainger.

iii In 2009/2010 the common area electricity data reported is for a sample of Grainger’s highest use blocks of flats – which we believe will account for the majority of the carbon emissions of the portfolio that Grainger is responsible for. We have utilised beginning and end of year bills to calculate the consumption. However, since bills are received at varying intervals and for different beginning and end of year dates the consumption is not all for the same period. Although we aim to improve this data in the future, this is a positive first step towards accurately measuring common area carbon emissions, expressive of Grainger’s commitment to expanding and improving its carbon reporting.

iv Carbon emissions are reported for all business related company car trips. Emissions are estimated based on the cost of fuel for each car each month, the average price per litre of fuel each month, and the average miles per litre of the relevant car. We are unable to report on taxi travel as service is usually hailed rather than ordered through an account.
