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.
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.
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.
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.
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.
PPN 06/21 (Procurement Policy Note 06/21) is a UK government policy requiring suppliers bidding for central government and NHS contracts over £5 million annually to submit a Carbon Reduction Plan demonstrating commitment to Net Zero by 2050.
Yes. PPN 06/21 was renamed to PPN 006 under the Procurement Act 2023. The requirements remain unchanged, and the Annex A template structure is identical.
A non-compliant Carbon Reduction Plan will result in your tender being rejected. Common issues include missing Scope 3 emissions, incorrect methodology, and unsigned declarations.
Yes, if you're bidding for contracts over £5 million annually. The threshold is based on contract value, not company size.
PPN 006 requirements for 2026 remain unchanged from PPN 06/21: suppliers must commit to Net Zero by 2050, report Scope 1, 2, and relevant Scope 3 emissions using DEFRA factors, complete the Annex A template, and publish the CRP on their website.
Professional CRP services typically range from £1,500–£5,000+ depending on scope coverage and support level.
