Terms of use

• GreenTrace is a prototype built for the IEEE ClimateChain Global Hackathon 2026. It is provided for evaluation and demonstration.
• It runs on Hedera testnet. Testnet HBAR, CO2e tokens and certificate NFTs have no monetary value and may be reset by the network.
• Marketplace listings are sample projects with illustrative details. Buying or retiring them does not offset real emissions and is not a claim you can make publicly.
• Certificates issued here are a demonstration of verifiable reporting, not third-party assurance or a regulatory filing.

• AI reads documents and suggests audits, ratings, baskets, reduction plans and report text. It can make mistakes.
• You are responsible for reviewing every value before you create an inventory, issue a certificate or publish anything based on it.
• Credit ratings, offset suggestions and reduction plans are decision support, not financial, investment, legal or environmental advice.

• Keep your sign-in details and your wallet secure. You are responsible for transactions you sign in your wallet.
• Upload only documents you are allowed to share, and do not upload other people's personal data beyond what appears on ordinary utility bills.
• You keep ownership of your content. You let GreenTrace process it to provide the service, as described in the privacy policy.
• Records written to Hedera or IPFS, such as certificates, hashes and transactions, are public and permanent.

• Do not attempt to break, overload or bypass the security of the service, including the AI rate limits and the one-time test HBAR grant.
• Do not use GreenTrace to misrepresent emissions or to make misleading environmental claims.

We may suspend accounts that break these rules.

GreenTrace is provided "as is", without warranties of any kind, and may be unavailable, changed or discontinued at any time. To the extent the law allows, its makers are not liable for any loss arising from its use, including decisions made on the basis of its outputs.

The GreenTrace source code is released under the MIT license. These terms cover the hosted service, not the code.
