If your business bids for UK private or public sector contracts, you already know rules of engagement have changed. Sustainability is no longer a “nice-to-have” paragraph tucked at the end of your tenders. It’s a strict, scored gateway making the difference between winning and losing the work.
Between PPN006 and PPN 06/21 (which mandate a formal Carbon Reduction Plan for major contracts) and PPN 06/20 (which enforces a minimum 10% Social Value evaluation weighting), procurement teams are actively filtering out suppliers who pay lip service to net zero.
The biggest hurdle for most organisations isn’t writing the policy. It’s proving execution. Accredited Carbon Literacy Training is an easy way to bridge that gap.
Embedding Carbon Literacy across your workforce transforms your tender responses, satisfies public procurement mandates, and powers your annual reporting.
1. Satisfying PPN 06/21 (PPN 006): Beyond “Tick-Box” Tenders
Under PPN 06/21 (often referenced as PPN006), any supplier bidding for central government, executive agency, or NHS contracts valued at £5m+ per annum must publish a compliant Carbon Reduction Plan (CRP).
A compliant CRP requires:
- A formal board-approved commitment to achieving Net Zero by 2050.
- Baseline and annual reporting for Scope 1, Scope 2, and key Scope 3 emissions (including business travel, employee commuting, waste, and transport).
- Clear, detailed environmental management measures detailing how you will achieve your reduction targets year-on-year.
Where Bidders Fail
Many companies commission an external consultant to calculate their carbon footprint and draft a CRP template. But when tender evaluators ask, “How will your operational staff deliver these reductions on site?”, generic plans fail.
The Carbon Literacy Solution
Listing accredited Carbon Literacy Project training inside your CRP satisfies the requirement for specific measures. It demonstrates your workforce has received independently verified training which identifies, measures, and eliminates emissions across daily roles.
2. Maximize Your 10% Social Value Score (PPN 06/20)
Under PPN 06/20, central government buyers must evaluate Social Value with a minimum 10% weighting. One of the core themes in the government’s Social Value Model is Theme 3: Fighting Climate Change.
Tender evaluators award top marks to bidders who provide quantitative, verifiable commitments rather than vague promises.
Vague Social Value Response (Low Marks):
“We are committed to sustainability and will encourage our staff to save energy and recycle where possible.”
Accredited Carbon Literacy Response (High Marks):
“We will deliver 1-day accredited Carbon Literacy Project training to 100% of our contract delivery team. Every participant will submit two externally audited carbon reduction pledges, targeting a verifiable 5–15% reduction in contract-specific Scope 1, 2 and 3 emissions.”
Why Evaluators Love These Commitments
- Externally Accredited: Certification is independently verified by The Carbon Literacy Project, giving bid evaluators total confidence in your claims.
- Upskilling the Local Workforce: It demonstrates investment in workforce skills and green capability, directly aligning with government social mobility and workforce development goals.
- Supply Chain Impact: You can extend training to your local sub-contractors and SMEs, proving you are actively decarbonising the broader supply chain.
3. Powering Annual Reporting & SECR Requirements
Winning the contract is only step one; PPN 06/21 and Streamlined Energy and Carbon Reporting (SECR) regulations require suppliers to report emission reductions annually to maintain compliance.
If your carbon footprint stays flat year after year, your public sector framework could be at risk.
Turning Pledges into Measured Data
To achieve genuine year-on-year carbon savings, you need behaviour change on the ground. During a Lead With Sustainability Carbon Literacy session, every employee must formulate two binding pledges:
- An Individual Workplace Action: Direct behavioural shifts in the workplace within their immediate control (eg cutting business mileage, reducing waste materials, optimising heating).
- A Group Workplace Action: Systemic operational improvements (eg switching to low-carbon construction materials, adding carbon reduction targets to supplier engagement processes).

Studies show that Carbon Literacy training consistently reduces each participant’s emissions by 5% to 15%. These immediate reductions provide the metrics you need to populate your annual SECR disclosures and CRP updates.
