Become a GreenTurtle

An afternoon's work, not a consultancy project.

You bring the vehicle list and whatever mileage evidence you already hold. The assessment tells you what is measured, what is estimated and what is sitting on a default — and you decide whether to publish it.

Verify the company

Companies House, with a work email. Limited companies only.

Bring the fleet

Import a CSV, connect FleetGenius, or add vehicles by registration.

Show the distance

Lease schedules, odometer readings or telematics. What is missing gets a default, in amber.

Read the assessment

Total, intensity, tier, and the number of figures resting on a default. Fix what you can before you issue.

Issue the mark

You get a code, a public record and the artwork. Or you keep it private — that is a legitimate answer too.

Human-centred AI, ingrained

The AI does the typing. You keep the judgement.

Nothing is submitted on your behalf and no figure is invented. Every suggestion arrives with the record it came from, and you approve it before it counts.

Reads your evidence

Upload the lease schedule, the mileage report, the expense export. The AI matches documents to vehicles and fills the assessment, showing which page each figure came from.

Explains every figure

Ask why a van's tonnage is what it is and you get the distance, the source, the factor and the uplift in plain English — not a formula.

Flags the defaults

It tells you which defaults are moving your total most, and what single piece of evidence would replace them. Usually it is one lease schedule.

Drafts the questionnaire

When a customer or tender sends a carbon questionnaire, the AI drafts the answers from your assessment and cites the certificate. You review and send.

Start your self-assessment

Limited companies only. We verify you on Companies House, then open your assessment.
