PPN 006 compliance guides for UK suppliers — what the Procurement Policy Note requires, how to write a Carbon Reduction Plan, sector-specific guidance, and the £5m tender threshold.
Procurement Policy Note 06/21 — now PPN 006 — requires every supplier bidding for UK central government contracts above £5 million per year to publish a compliant Carbon Reduction Plan (CRP). The rule is enforced at the bid stage: no CRP, no contract. NHS Supply Chain extended the same requirement to its supplier base, which is why most SMEs first encounter PPN 006 through an NHS or local-authority tender form.
A compliant plan is a short, public PDF that states the supplier's baseline emissions across Scope 1, Scope 2 and the six mandated Scope 3 categories, names a 2050 net zero target, and lists the projects the business will deliver to get there. The structure is fixed by the Cabinet Office's Annex A template — buyers compare submissions against that template, so deviating from it is the most common reason CRPs are rejected.
The guides below cover the full lifecycle: what PPN 006 actually says, how to build a CRP from scratch, sector-specific guidance for construction and NHS suppliers, and when working with a consultant is worth the cost.
