Question

How does the Coverage indicator work — and how do we manage the KPI/Coverage trade-off?

First, the scope: the Coverage indicator only applies to large companies with 1,000 or more employees. It serves as a multiplying factor for the Measures and Certifications indicator scores, with a minimum threshold of 25, and measures how widely sustainability practices are deployed across operations, expressed as a percentage.

The trade-off is real: adding a new KPI with low coverage can lower the Coverage score even as the Reporting score improves — a KPI reported for 20% of sites (say, environmental training at headquarters only) pulls the Coverage average down. Reporting evaluates what you have declared and measured; Coverage evaluates how widely it is deployed. Before declaring a new KPI, confirm the actual coverage figure: below 50% of the relevant scope, the benefit is limited or negative. The better approach is to increase actual deployment before declaring, or to expand coverage of already-reported KPIs above 50%, where the scoring mechanics begin to reward the declaration. If two proxy KPIs both exceed 50% coverage and are externally assured, they can combine with the bonus provision to reach 100/100 in that pillar. Broad deployment of fewer, well-covered KPIs consistently outperforms a long list with narrow reach.

What moves Coverage to 100/100 beyond certifications: extending ISO certifications to all significant sites; tracking and reporting H&S training completion for all locations; deploying supplier sustainability screening across all suppliers; sourcing the majority of energy from renewables; and conducting risk assessments across all relevant operations. The most common gaps are commercial offices and recently acquired subsidiaries left out of certification scope or training programmes.
