The Mapping Agent in action

Procurement item

  • Description: Coffee
  • Quantity: 25
  • Unit: kg

Agent reasoning

Emissions

≈ 210 kg CO₂e

25 kg × 8.40 kg CO₂e/kg

  • Keyword: Coffee
  • Attribute: Ground, cradle to supermarket gate
  • Library: Agribalyse

How it works

  1. Step 1

    Drop your file
    Export your Scope 3 procurement data to Excel and upload it. No template, no cleanup.

  2. Step 2

    Agents do the matching
    Every line gets mapped to a GHG-compliant factor, with units converted. Ambiguous items are flagged, and only a fraction needs human review.

  3. Step 3

    Get audited emissions
    Results in minutes, with every assumption logged and exportable for compliance.

  4. Step 4

    Push to your carbon tool
    Refine with your AI of choice (Claude, ChatGPT, Copilot), then send the results straight into your current carbon accounting tool (e.g., Carbon+Alt+Delete, or custom xls upload)

What you get

  • Minutes, not weeks
    Thousands of procurement lines go from raw export to audited emissions in minutes. The agents handle the matching end to end, turning weeks of manual work into a single short run.
  • Accurate on messy real data
    Real procurement files are full of cryptic codes, duplicates, and outliers. We decode the jargon, collapse the duplicates, and route every line to the right factor. Anomalies get caught before they reach your total.
  • Audit-proof & in your control
    Every assumption is logged and exportable, built strictly to the GHG Protocol. You stay in control: refine results with your own AI and review the gaps we flag.
