What is PPN 06/21? Requirements + Free CRP Template 2026

By Frazer Holroyd · 10 min read · Carbon Reporting · Updated February 2026

PPN 06/21 (Procurement Policy Note 06/21) was introduced by the Cabinet Office in June 2021. It requires suppliers bidding for major UK government contracts to demonstrate their commitment to achieving Net Zero greenhouse gas emissions by 2050. The policy uses public procurement as a lever to drive carbon reduction across the UK economy.

Any business — regardless of size — that bids for public sector contracts over £5 million annually must submit a compliant Carbon Reduction Plan. The threshold is based on contract value, not company size. This applies to central government contracts and is increasingly adopted by local authorities and NHS trusts.

What Are the PPN 06/21 Requirements?

A compliant Carbon Reduction Plan must include seven key elements: commitment to Net Zero by 2050, current Scope 1 emissions (company vehicles, gas boilers), current Scope 2 emissions (purchased electricity), relevant Scope 3 emissions (supply chain, business travel, waste), environmental management measures, a signed board-level declaration, and publication on your company website.

PPN 06/21 vs PPN 006 — What Changed?

In February 2025, PPN 06/21 was renamed to PPN 006 under the Procurement Act 2023. The requirements remain identical — the change is nomenclature only. The Annex A template structure is unchanged.

Does PPN 06/21 Require Scope 3 Emissions?

Yes. The CRP template explicitly asks suppliers to report Scope 3 emissions where they are "relevant." You don't need to report all 15 GHG Protocol categories — focus on the categories most material to your business. Common Scope 3 categories include business travel, employee commuting, purchased goods and services, and waste disposal.

Common PPN 06/21 Mistakes

NHS-Specific Requirements

From April 2024, the NHS extended Carbon Reduction Plan requirements to all new procurements — not just those over £5 million. NHS suppliers must also demonstrate alignment with NHS Net Zero targets and Green Plan objectives.
