How it works
The path to full insight into your CO2e emissions is Simple. Our AI converts 100% activity‑based carbon data for your entire company from supplier invoices in minutes.
What happens, step by step.
A closer look at the three-step process — and what the AI is actually doing at each stage.
Upload any business document
Simple accepts the documents you already produce — no special exports or integrations required. Each document type unlocks a different kind of carbon intelligence.
- Invoices & delivery notes — Actual CO₂e post-purchase · for compliance reporting
- Quotations & offers — Indicative CO₂e before commitment · for procurement planning
- Bills of Materials (BOMs) — Product-level footprint · for construction & manufacturing
Carbon as a procurement KPI. Before you commit.
Simple processes supplier quotations alongside invoices. Upload competing bids and compare suppliers not just on price — but on CO₂e per unit, total emissions, and indicative ETS cost exposure.
- Construction: evaluate tenders against LEED, BREEAM, or carbon budgets
- Industrial: use quotation CO₂e to negotiate or justify supplier switches
- Finance: flag high-emission procurement before it locks in future Scope 3
Values are indicative — based on quotation data and ecoinvent 3.9. Confirmed on invoice delivery.
Choosing Maier vs. Zement Nord: save 10.8 t CO₂e at €7.50/t more. Carbon cost of cheaper option: +€54 per 100 m³ at current ETS.
The science behind the number.
Every CO₂e figure Simple produces is traceable to internationally recognised databases and LCA methodology.
Best available factor — always
For every line item, Simple calculates all emission factor and selects the most efficient one available (from manufacturer PCF, EPD, activity-based data or spend-based). The source and tier are transparent per calculation.
Geography-specific matching
Emission factors vary significantly by country and region. Simple applies geography-specific ecoinvent datasets where available — and logs the location assumption when it must approximate. Every factor version is recorded for audit.
EPD integration for construction
When Environmental Product Declarations (EN 15804) are available, Simple uses them as product-specific factors — replacing ecoinvent with verified, product-level data. Relevant for LEED, BREEAM, and EU Taxonomy alignment.
Automated vendor consolidation
AI identifies duplicate suppliers, name variations, typos, and entity changes across your supplier base. Clean vendor data is a prerequisite for meaningful emissions analysis — Simple handles it automatically.
Built on recognised standards
What Simple covers — and what it doesn't.
Coverage depends on which documents you upload — not fixed product limitations.
Of all line items extracted from uploaded documents, over 90% are matched to an emission factor without manual intervention. Items below confidence threshold are flagged for review — not silently dropped or estimated.
