Simply put
What it means in ordinary work
It means helping and requiring key suppliers to lower emissions, not only asking for a number. It needs clear data, targets, support and follow-through.
Why it matters
For many organisations, purchased goods and services dominate emissions. Supplier action is essential to credible climate targets and transition planning.
A hypothetical in practice
A hypothetical buyer segments suppliers by emissions and influence, asks high-impact suppliers for science-aligned targets and site-level data, and includes reduction milestones in contract reviews.
Common pitfalls
Collecting emissions data without a reduction plan can create reporting burden with little change.
Suppliers may lack capability or finance. Provide proportionate support and differentiate expectations.
