# 4-1. State of Regenerative NFTs

Through the issuance of Regenerative NFTs related to carbon credits like J-Credit, not only corporations within Japan but also individuals and international entities can indirectly invest in Japan's environmental value.

SINRA's Regenerative NFTs have two distinct states.

An "Certified Carbon Credit NFT" refers to an NFT that represents the right to request the transfer of carbon credits that have been certified by carbon credit certification authorities (like the Ministry of the Environment in the case of J-Credit). Users who hold an Authenticated Carbon Credit NFT have the right to request the transfer of the carbon credits represented by that specific NFT in the name of the holding user.

An "Uncertified Carbon Credit NFT" refers to an NFT that represents the right to request the transfer of carbon credits that are in a state of pending certification by the carbon credit certification authorities. After the NFT has been issued and circulated, if the carbon credits are subsequently certified, the status on the NFT's metadata is updated, turning it into an Authenticated Carbon Credit NFT.

Details on the NFT status and the behavior of the NFT can be found in Chapter 5.2.<br>
