The embodiment can be applied to a blockchain network, as shown in fig. 1, and the blockchain-based carbon efficiency code generating method in the embodiment includes the following steps:

step S110, the identity authentication node receives an identity authentication request sent by at least one active identification carrier of a target enterprise.

Wherein the authentication request includes: the at least one active identification carrier is used for collecting the energy consumption data.

The energy consumption data may be consumption data of any energy source, for example, the energy consumption data may be carbon consumption data, natural gas consumption data, crude oil consumption data, electric energy consumption data, or the like. The active identification carrier may be used to collect energy consumption data, and the active identification carrier may also interact with the identity authentication node and the data processing node. Illustratively, the active identification carrier may be a smart meter, a carbon consumption detection terminal, or the like. The carbon consumption detection terminal may include a carbon dioxide sensor, a calculation module and a communication module, where the carbon dioxide emission amount in a certain time may be detected by the carbon dioxide sensor, the calculation module calculates the quality of carbon consumption (corresponding to the carbon consumption data in the embodiment) by using the detected carbon dioxide emission amount, and the quality of carbon consumption may be transmitted to the data processing module by the communication module.

The identity information of the active identification carrier may be set according to actual requirements, for example, the identity information of the active identification carrier may include: identification coding of the active identification carrier, application of the active identification carrier, target enterprises to which the active identification carrier belongs, and the like. The identification code is used for uniquely identifying an active identification carrier, and can be any identification or code, for example, the identification code can be an industrial internet identification. The target enterprise may be any enterprise, factory, organization, group, etc. that requires carbon efficiency evaluation, and the "target" in the target enterprise does not constitute a limitation on the target enterprise.

In one embodiment, for each active identification carrier in at least one active identification carrier, the active identification carrier may generate an identity authentication request according to identity information of the active identification carrier, and send the identity authentication request to an identity authentication node, where the identity authentication node receives the identity authentication request sent by the active identification carrier.

It should be noted that the target enterprise may have a plurality of active identification carriers, where the plurality of active identification carriers may include a plurality of types, and each type of active identification carrier may collect one type of energy consumption data. When the target enterprise performs carbon efficiency evaluation, all active identification carriers for providing energy consumption data for the carbon efficiency evaluation need to send an identity authentication request to an identity authentication node to perform identity information auditing.

Step S120, for each active identification carrier, the energy consumption data is sent to the data processing node in response to the verification of the identity information of the active identification carrier through the identity authentication node.

The identity authentication node performs auditing on the identity information of each active identification carrier. For each active identification carrier in at least one active identification carrier, when the identity authentication node determines that the identity information of the active identification carrier is true, determining that the identity information of the active identification carrier passes the verification of the identity authentication node, otherwise, determining that the identity information of the active identification carrier does not pass the verification of the identity authentication node.

In one embodiment, the active identifier carrier may register the identity information of the active identifier carrier in advance at the identity authentication node, when the identity authentication node receives the identity authentication request sent by the active identifier carrier, the identity authentication node compares the identity information registered by the active identifier carrier with the identity information in the identity authentication request, when the identity information registered by the active identifier carrier is identical to the identity information in the identity authentication request, the identity information in the identity authentication request is determined to be true, the identity information of the active identifier carrier is determined to pass the verification of the identity authentication node, or else, the identity information of the active identifier carrier is determined to not pass the verification of the identity authentication node.

In one embodiment, for each active identification carrier in at least one active identification carrier, when the identity information of the active identification carrier passes the verification of the identity authentication node, the identity authentication node sends an identity authentication passing message to the active identification carrier, and when the active identification carrier receives the identity authentication passing message, the active identification carrier sends the energy consumption data acquired by the active identification carrier to the data processing node; and when the identity information of the active identification carrier does not pass the verification of the identity authentication node, the identity authentication node sends an identity authentication failure message to the active identification carrier.

Step S130, the data processing node determines a carbon emission accounting and carbon efficiency evaluation model of the target enterprise according to the energy consumption data sent by each active identification carrier.

The carbon emission accounting and carbon efficiency evaluation model is used for determining carbon efficiency evaluation information according to the energy consumption data. For example, the carbon emission accounting and carbon efficiency evaluation model may include: emission factors, carbon neutralization rate accounting strategies, carbon emission amount accounting strategies, and carbon efficiency value accounting strategies.

In one embodiment, the data processing node has stored therein a plurality of emission factors, a calculation strategy for carbon neutralization, a calculation strategy for carbon emission, and a calculation strategy for carbon efficiency values. The data processing node determines emission factors corresponding to the energy consumption data, and then generates a carbon emission accounting and carbon efficiency evaluation model according to the emission factors corresponding to the energy consumption data, the accounting strategy of the carbon neutralization rate, the accounting strategy of the carbon emission and the accounting strategy of the carbon efficiency value. Wherein the emission factor characterizes a coefficient of greenhouse gas emissions per unit of production or consumption activity.

In one embodiment, the data processing node transmits the energy consumption data transmitted by each active identification carrier and the carbon emission accounting and carbon efficiency evaluation model of the target enterprise to the carbon efficiency evaluation node.

In one embodiment, when the identity information of the active identity carrier passes the verification of the identity authentication node, the identity authentication node may further synchronize an identity authentication passing message of the active identity carrier to the data processing node, where the identity authentication passing message includes an identification code of the active identity carrier. When the active identification carrier transmits the energy consumption data acquired by the active identification carrier to the data processing node, the identification code of the active identification carrier can also be transmitted simultaneously. The data processing node determines whether the active identification carrier identified by each identification code passes the identity authentication of the identity authentication node according to the identity authentication passing message, and when the active identification carrier identified by each identification code is determined to pass the verification of the identity authentication node, the data processing node determines a carbon emission accounting and carbon efficiency evaluation model of the target enterprise according to the energy consumption data sent by each active identification carrier.

And step S140, determining the carbon efficiency evaluation information of the target enterprise by the carbon efficiency evaluation node according to the carbon emission accounting and carbon efficiency evaluation model and the energy consumption data.

Wherein, the carbon efficiency evaluation information may include: carbon emissions, carbon efficiency, and carbon neutralization rate.

In one embodiment, the energy consumption data sent by each active identification carrier is multiplied by the emission factor corresponding to each energy consumption data to obtain the carbon emission amount corresponding to each energy consumption data, then the carbon neutralization rate accounting strategy, the carbon emission amount accounting strategy and the carbon efficiency value accounting strategy can be invoked, and the carbon emission amount corresponding to each energy consumption data is utilized to obtain the carbon emission amount, the carbon efficiency value and the carbon neutralization rate of the target enterprise.

In one embodiment, the carbon emission of the target enterprise may be a sum of carbon emissions corresponding to the respective energy consumption data, and then the calculation strategy of the carbon emission in the carbon emission calculation and carbon efficiency evaluation model may specifically include: and adding the carbon emission corresponding to each energy consumption data to obtain the carbon emission of the target enterprise.

The carbon efficiency value can be the ratio of the unit industrial increment carbon emission of the enterprise to the average value of the unit industrial increment carbon emission of the industry at the same time of the enterprise. The unit industrial increment value carbon emission (unit: ton/ten thousand yuan) is the ratio of the carbon emission (unit: ton) of the enterprise in unit time to the industrial increment value (unit: ten thousand yuan) of the enterprise in unit time. The calculation strategy of the carbon efficiency value in the carbon emission calculation and carbon efficiency evaluation model may specifically include: and determining the carbon emission of the unit industrial increment value of the target enterprise according to the carbon emission of the target enterprise in the carbon efficiency evaluation information and the industrial increment value of the target enterprise in the same unit time with the carbon emission of the carbon efficiency evaluation information. And then, obtaining the carbon efficiency value of the target enterprise according to the average value of the carbon emission of the unit industrial increment value of the target enterprise and the carbon emission of the unit industrial increment value of the same period of the industry in which the target enterprise is located.

The carbon neutralization rate may be a ratio of the carbon neutralization amount to the carbon emission amount, and then the calculation strategy of the carbon neutralization rate in the carbon emission calculation and carbon efficiency evaluation model may specifically include: and determining the carbon neutralization rate according to the carbon neutralization amount and the carbon emission amount of the enterprise, and determining the carbon neutralization rate. Wherein the carbon neutralization amount is the sum of zero carbon electric power reduction carbon emission and carbon fixation reduction carbon emission. Carbon sequestration refers to a measure of increasing the carbon content of a carbon reservoir other than the atmosphere, and accordingly, carbon sequestration-reduced carbon emissions may be carbon emissions offset by carbon sequestration (e.g., carbon emissions offset by tree planting), zero carbon power may be power other than coal power, e.g., wind power, hydropower, etc., and zero carbon power-reduced carbon emissions may be obtained by multiplying the zero carbon power by an electrically corresponding emission factor.

In one embodiment, the carbon efficiency evaluation node sends the carbon efficiency evaluation information of the target enterprise to the carbon efficiency code generation node.

And step S150, the carbon efficiency code generating node determines the carbon efficiency evaluation grade information of the target enterprise according to the carbon efficiency evaluation information.

The carbon efficiency rating information may include a carbon efficiency rating of the target enterprise. The carbon efficiency evaluation grade information may represent the energy utilization condition and the carbon emission condition of the target enterprise.
