Frequently asked questions
Everything you need to know about certificates, offsetting and on-chain verification.
What exactly is a MarchioGreen certificate?
It’s an official document attesting that your company has offset a certain amount of CO₂, recorded as a token on the Polygon blockchain and publicly verifiable.
How do I verify a certificate?
From the public certificate page you can check the data and follow the direct link to the transaction on Polygonscan. Verification is open to anyone, with no account needed.
Can I use the mark in my communication?
Yes. With the certificate you get the right to use the MarchioGreen badge on your website, products, social, email and sales materials.
Why do you use Polygon?
Polygon is a public, low-energy blockchain with low costs and wide adoption: ideal for recording immutable certificates sustainably.
How do I purchase a certificate?
The process is B2B and tailored: contact us, we define the CO₂ amount together and proceed with issuance. The technical management is entirely on us.
Can the certificate expire or be cancelled?
No. Once recorded on-chain, the certificate is permanent and immutable: it remains verifiable over time.
