About SustainLedger

Automating Carbon Reporting for UK Government Tenders

What We Do

SustainLedger automates the generation of PPN 006 (formerly PPN 06/21) compliant Carbon Reduction Plans for UK businesses bidding on NHS and Central Government contracts. We transform your transaction data into tender-ready compliance documents in minutes, not days.

Missing a Carbon Reduction Plan is the fastest way to get disqualified from tenders valued at £5 million or more per annum. We eliminate this risk by automating the technical complexity, allowing you to focus on winning the bid.

How We Do It

Our platform uses a combination of AI-powered classification, rule-based matching, and semantic analysis to automatically categorize your business transactions into the correct carbon emission categories.

AI-Powered Classification

Advanced machine learning models analyze transaction descriptions and supplier names to automatically identify carbon categories with high confidence scores.

Rule-Based Matching

Extensive supplier database and pattern matching ensure accurate classification for common business expenses (utilities, travel, fuel, etc.).

DEFRA 2025/2026 Factors

All emissions calculations use the latest official UK Government conversion factors published by DESNZ/DEFRA, ensuring full compliance.

PPN 006 Compliance

Automatic grouping into mandatory Scope 3 categories (Upstream Transport, Waste, Business Travel, Employee Commuting, Downstream Transport) as required by Cabinet Office guidance.

Benefits

Time Savings

Generate compliant reports in minutes instead of spending days manually categorizing transactions and calculating emissions.

Accuracy & Compliance
