VSME OS turns energy bills and travel records into a GHG Protocol-based carbon declaration — ready to send to any procurement team, worldwide.
Self-attested reports · Based on GHG Protocol & ISO 14064-1:2018 · Full methodology →
How It Works
Fill in energy bills, fuel usage, and business travel across Scope 1, 2, and 3. Tooltips on every field tell you exactly where to find each number.
Our engine applies the correct national emission factors for your country — ADEME for France, DEFRA for the UK, EPA for the USA — and produces Scope 1, 2, and 3 totals.
Sign the declaration and download a 4-page GHG Protocol-based PDF. Send it to your buyer's procurement team. No consultant required.
Most suppliers complete their first report in a single session. Have your utility bills and travel records to hand before you start.
