Net Zero with bidpiston
count. calculate. comply.

Win more public sector work.

Public buyers increasingly expect clear, credible carbon data. Under PPN 006 (formerly PPN 06/21), suppliers bidding for in-scope central government contracts must publish a Carbon Reduction Plan (CRP) committing to Net Zero by 2050, report Scopes 1 & 2, and disclose a defined subset of Scope 3 emissions - then update and republish annually with director approval. For procurements advertised on or after 24 Feb 2025, this is a condition of participation for contracts >£5m p.a. (including VAT). GOV.UK+1

why counting your emissions matters

Eligibility & risk control:
Be bid-ready for central government opportunities; avoid disqualification on compliance grounds. GOV.UK
Stronger scores & trust:
Evidence real delivery against your plan, not promises - buyers value transparency and governance (board-approved CRP, public link on your site). GOV.UK
Cost & performance:
Carbon data exposes waste (travel, energy, logistics) you can cut - lowering cost while hitting targets.
Future-proofing:
Use the latest UK conversion factors for credible numbers that stand up to scrutiny. GOV.UK+1

What PPN 006 / PPN 06/21 requires (in plain English)

Your Carbon Reduction Plan must:

Commit to Net Zero by 2050 (organisational).
Report Scope 1 & Scope 2 emissions for the last financial year.
Report five Scope 3 categories: 4 Upstream Transport & Distribution, 5 Waste in Operations, 6 Business Travel, 7 Employee Commuting, 9 Downstream Transport & Distribution.
Be approved by a director/board, published on your UK website, and updated at least annually.
Use the CRP template and meet the Technical Standard outlined by the Cabinet Office. GOV.UK+1

Who it applies to: In-scope central government procurements >£5m p.a. advertised from 24 Feb 2025 (PPN 006; earlier procurements followed PPN 06/21). Many buyers and frameworks still reference “PPN 06/21” but expect the same core CRP content. GOV.UK
