On your Proof of Carbon Credit Retirement page (for example), scroll to the bottom and click on the ‘VIEW CARBON PROVENANCE’ button to open the page showing the credit's transaction history.
On the Carbon Provenance page, scroll to the bottom and note the Serial Number on the Transfer event.
Select and copy the serial number using browser methods or from your keyboard with Ctrl+C (Windows) or Command-C (Mac). In this example, copied: 12082-384723093-384800545-VCS-VCU-304-VER-CN-1-191-01012008-31122008-0.
Next, click on the View issuance on Verra link which will open in a new browser tab the projects table in the Verra Carbon Standard registry, targeting the VCUs tab with the table filtered by the project-ID.
Scroll the table to the right until you see the Serial Number column.
Click the Filter icon on the column and paste the copied serial number into the Contains field.
Click the Filter button and this will filter the table based on the serial number provided.
