Reports that are verifiably unchanged
Every report Emitraq issues carries a tamper-evident seal. Scan the QR code on any report and confirm in seconds that it is exactly the document Emitraq produced — unchanged and unedited. Useful when a client, an auditor or a regulator asks you to prove it.
Tamper-Evident Seal
Every report is sealed at the moment of issue. Any change after that is immediately detectable.
QR Code Confirmation
Anyone with the QR code can scan it to confirm the report is unchanged. No Emitraq account needed.
Tamper-Evident Records
The seal serves as a permanent, publicly verifiable timestamp of the report at the time of creation.
Independent Confirmation
Anyone can confirm a report by scanning its QR code. No Emitraq account required.

Audit-Ready
When a client, auditor or regulator asks you to prove a report hasn't been edited, you can show them in seconds.
How report verification works
When you generate a report, Emitraq creates a tamper-evident seal of the entire report content. This creates a permanent, publicly verifiable record that the report has not been altered since it was issued.
- Report generated with fuel and CO₂ data
- Tamper-evident seal computed from the complete report content
- Seal registered with a permanent, publicly verifiable timestamp
- QR code generated linking to the verification record
- Anyone can scan QR code to confirm the report is unchanged
Verification confirms a report has not been altered since it was issued. It does not certify the accuracy of the original measurement.
The confirmation flow
Confirming a report doesn't require an Emitraq account or special software. Anyone can scan the QR code on any report and see the verification record in their browser.
- Step 1: Receive report PDF with QR code
- Step 2: Scan QR code with any phone camera
- Step 3: Browser opens the verification page
- Step 4: Shows the seal and issue timestamp
- Step 5: Confirms the report has not been altered since issue
Verification confirms a report has not been altered since it was issued. It does not certify the accuracy of the original measurement.
Reports that stand up to scrutiny
