How to Use Carbon Data to Win Tenders and RFP Submissions

Procurement teams at large corporations and public sector bodies are now scoring carbon data as part of tender evaluation. In many cases, having your emissions calculated and documented gives you a measurable advantage over competitors who do not. This guide explains how carbon data fits into modern procurement and how to present it effectively.

How Carbon Data Is Scored in Tenders

Tenders increasingly use Environmental, Social, and Governance (ESG) or Corporate Social Responsibility (CSR) weighting — typically 5–15% of total tender score. Within that, carbon-related criteria commonly include:

• Does the supplier have a measured GHG inventory? (Pass/fail gate)
• Has it been calculated to GHG Protocol standard? (Methodology check)
• Is a supporting verification document or URL provided? (Evidence requirement)
• Has the supplier set a reduction target? (Optional but scored)
• Year of the most recent data (Recency check — data over 3 years old typically scores zero)

A supplier with accurate, documented Scope 1/2/3 data scores full marks on these criteria. A supplier who responds "we are working on it" scores zero.

Public Procurement: The Growing Requirement

UK Cabinet Office and Crown Commercial Service (CCS): As of 2023, suppliers to central government above £5M contract value must have a carbon reduction plan including Scope 1 and 2 emissions. This requirement is now embedded in most major framework procurements.

EU Green Public Procurement (GPP): EU Directive 2014/24 allows contracting authorities to include environmental criteria. CSRD acceleration has driven more EU procurement bodies to add GHG scoring criteria to supplier qualification.

NHS Supply Chain: Evergreen Sustainability Assessment scores suppliers on GHG measurement, with higher scoring tiers for third-party verified data.

Local authorities and regional bodies: Many UK and EU local authorities now include carbon commitments in supplier qualification questionnaires for service contracts above threshold.

Corporate Procurement: What Goes in the Tender Response

For a private sector RFP or ITT (Invitation to Tender) with a sustainability section:

In the sustainability section of your response: - State your Scope 1, 2, and 3 totals in tCO2e for the most recent reporting year - Name the methodology: "Calculated in accordance with the GHG Protocol Corporate Standard using DEFRA 2023 emission factors" - Reference the year: "Reporting year: [year], based on actual utility bill and fuel data"

In the evidence or supporting documents tab: - Upload your Carbon Passport PDF or paste the verification URL (e.g. decarbonops.com/verify/[your-token]) - A public URL is preferable to a static PDF — it is always the most recent version and can be independently verified by the procurement team

As an optional differentiator: - Describe one or two specific reduction actions you have taken (LED lighting upgrade, renewable energy tariff, fleet electrification) - If you have a reduction target, state it: "We are targeting a 30% Scope 1 and 2 reduction by 2030 from a 2024 baseline"

Responding to "Do You Have a Carbon Reduction Plan?"

1. This is increasingly a pass/fail question on UK government tenders. A credible carbon reduction plan for an SME contains:
2. Scope 1 and 2 baseline (your current measured figure)
3. At least one specific reduction action (not vague commitments)
4. A target year and percentage reduction

DeCarbonOPS gives you the baseline (step 1) in under 20 minutes. Steps 2 and 3 are your business decision — but having the baseline is the prerequisite for everything else. Without measured data, you cannot claim a plan.
