Calculation Methodology

Calculation Methodology Why It Matters


Our sustainability goals are aligned with our priority areas. Each of our eight goals has a series of target metrics against which our progress can be assessed.

To this end, we have defined a clear methodology for calculating each target metric, enabling us to measure performance accurately and consistently. We believe that transparency is an important driver of trust and accountability with our stakeholders, and in that spirit, we are publishing a summary of our calculation methodology.

This summary is available for download here. For detail on performance against our target metrics, see our latest Performance Metrics Sheet, here.
