Start with decisions
Identify where sustainability information should influence investment, procurement, product or risk choices. The decision determines which measures need consistent definitions and dependable ownership.
Strengthen the data chain
Trace information to its source, document assumptions and establish review controls. Focus first on material indicators rather than collecting metrics that have no clear use.
Connect reporting with management
Use the same evidence for external disclosure and internal review where possible. This reduces reconciliation effort and helps leaders see how performance connects to action.
