Getting started

1. Create an account

Head to /signup, enter an email and a password, and confirm. No credit card, no salesperson named Brad. Free tier ships with 25 calculations a month — enough to get a feel for things and validate the numbers against your own datasheets.

2. Calculate your first device

Once logged in, the dashboard puts the Calculator one click away. Pick a category (laptop, server, switch, etc.), enter brand and model if you have them, otherwise drop in the specs and let the parametric engine handle it. Country defaults to where you signed up from — change it if the device lives somewhere else.

Hit Calculate. The result comes back in milliseconds: production, transport, use phase, end-of-life, total CO₂e, and reuse savings if applicable. Every line item links to the source paper it came from.

3. Generate a certificate

From the result page, click Generate certificate. You get an A4 PDF with a unique certificate number, a QR code that points to a public verification page, and the full lifecycle breakdown laid out the way auditors prefer to see it. Free plan generates the PDF on Pro and above; the verification page works for everyone.

4. Wire in the API (optional)

If you want to skip the UI for bulk work, head to /api-keys in the app and create a key. The full REST reference is at /docs/api. Sandbox keys return deterministic fixtures so you can integrate without burning through your live quota.

5. Bring in your fleet

On Pro and above, the Batch tool takes a CSV up to 10,000 rows. Upload, map columns, hit go. Output comes back as CSV or JSON with per-row breakdowns plus aggregate totals — drop them straight into a CSRD report or a board deck.

What to read next

• Calculator — every field explained, including the ones that look optional but really aren’t.
• Inventory & batch — manage assets, upload CSVs, get aggregate analytics.
• Reports & certificates — exports, formats, white-label setup.
• REST API — when you’re ready to skip the dashboard entirely.
