Method, device, storage medium and program product for carbon trading
The present disclosure provides a method, a device, a storage medium and a program product for carbon trading. The method for carbon trading includes acquiring identification data and carbon behavior data of a transport device, the carbon behavior data indicating at least one of carbon consumption behavior and carbon emission reduction behavior of the transport device and the identification data including at least an identity corresponding to the transport device; in response to determining that the identity is in a predetermined identity set, acquiring an attribute corresponding to the transport device based on the identity; and determining, based on the carbon behavior data and a first smart contract matching with the attribute, a carbon emission reduction equivalent corresponding to the carbon behavior data, the first smart contract being provided for converting the carbon behavior data to the carbon emission reduction equivalent; transmitting the carbon emission reduction equivalent to a blockchain platform to store in a first account associated with a first object, the first object being associated with a plurality of transport devices; and publishing carbon trading associated with the carbon emission reduction equivalent in the first account as a blockchain transaction.
1. A method for carbon trading, comprising:
acquiring identification data and carbon behavior data of a transport device, the carbon behavior data indicating carbon consumption behavior and carbon emission reduction behavior of the transport device, and the identification data including at least an identity corresponding to the transport device;
in response to determining that the identity is in a predetermined identity set, acquiring an attribute corresponding to the transport device based on the identity;
determining, based on the carbon behavior data and a first smart contract matching with the attribute, a carbon emission reduction equivalent corresponding to the carbon behavior data, the first smart contract being provided for converting the carbon behavior data to the carbon emission reduction equivalent;
transmitting the carbon emission reduction equivalent to a blockchain platform to store in a first account associated with a first object, the first object being associated with a plurality of transport devices; and
publishing a carbon trading associated with the carbon emission reduction equivalent in the first account as a blockchain transaction;
in response to a request for issuing carbon tokens from the first object, acquiring a locking-pending amount of a carbon emission reduction voucher or the carbon emission reduction equivalent in the first account;
determining an issuance amount of carbon tokens based on a predetermined ratio and the locking-pending amount;
generating, via a second smart contract for issuing the carbon tokens, the issuance amount of carbon tokens in the first account; and
transferring the locking-pending amount of the carbon emission reduction voucher or the carbon emission reduction equivalent from the first account to a second account,
wherein transmitting the carbon emission reduction equivalent to the blockchain platform comprises:
packaging the carbon emission reduction equivalent to transmit to the blockchain platform in response to at least one of i) reaching a preset time interval and ii) a data amount of the acquired identification data and the carbon behavior data exceeding a predetermined value.
2. The method of claim 1 , further comprising:
in response to at least one of i) reaching the preset time interval and ii) the data amount of the acquired identification data and the carbon behavior data exceeding the predetermined value, packaging the identification data and the carbon behavior data to transmit to distributed storage devices; and
packaging a hash value of the identification data and the carbon behavior data to transmit to the blockchain platform.
