Transparent Methodology
Carbon Data You Can Explain and Defend
When procurement teams, auditors, or corporate buyers ask how you calculated your emissions, you need more than a number. Our methodology produces structured, documented carbon data that stands up to scrutiny.






Our Approach
From Your Records to Defensible Data
A structured methodology that produces carbon data you can confidently share with clients, procurement teams, and auditors
Step 1
Documented Data Sources
Structured data collection from your existing records
We connect directly to your accounting software to extract reconciled financial data. Every data point is traceable to its source, creating a clear audit trail from the start.
For SMEs with incomplete records, we identify gaps upfront and apply documented assumptions based on industry benchmarks and GHG Protocol guidance. Nothing is hidden or unexplained.
Step 2
Spend-Based Method
Transparent calculation with explainable methodology
We use spend-based emission factors from UK Government DESNZ data to convert your financial records into carbon equivalents. Every calculation step is recorded and explainable.
When clients or auditors ask how you arrived at a figure, you will have a clear answer. Our methodology documentation shows exactly which emission factors were applied and why.
Step 3
Enhanced Defensibility
Activity-based precision where it matters most
For material emission sources like energy and transport, we collect activity data directly. This provides higher precision where it makes the biggest difference to your footprint.
The hybrid approach balances practicality with defensibility. Spend-based methods cover broad categories efficiently, while activity-based methods deliver traceable precision for your largest emission sources.
