Examples:
as shown in fig. 1, the blockchain-based carbon neutralization management method provided in the first aspect of the present embodiment may be performed by, but not limited to, a computer device with a certain computing resource, for example, a platform server, a personal computer (Personal Computer, PC, refer to a multipurpose computer with a size, price and performance suitable for personal use, a desktop computer, a notebook computer, a small notebook computer, a tablet computer, an ultrabook, etc. all belong to a personal computer), a smart phone, a personal digital assistant (Personal Digital Assistant, PDA), or an electronic device such as a wearable device. As shown in fig. 1, the carbon neutralization control method may include, but is not limited to, the following steps S1 to S10.
S1, periodically recognizing carbon sink quantity in a unit period for a carbon sink enterprise, and issuing a carbon sink certificate for the carbon sink enterprise according to a carbon sink quantity recognition result, wherein the carbon sink certificate comprises, but is not limited to, recognized carbon sink quantity and the like.
In the step S1, the carbon sink-free enterprise may be, but is not limited to, a planting farm or the like. Specific ways of identifying the carbon sink are existing ways, such as sample method investigation (i.e. obtaining the average carbon density of vegetation through a sample plot and then multiplying the carbon density of different vegetation by the corresponding area to obtain the carbon content of the ecosystem), site observation (most typically foundation observation of CO2 using the principle of vorticity correlation), etc. The period of carbon sequestration may be accurate to date, week, month or quarter, etc. to identify carbon sequestration within a day, week, month or quarter, etc. In further detail, the carbon sink certificate also includes, but is not limited to, a certificate unique number, an issue timestamp, an enterprise unique number of the net carbon sink enterprise, and the like.
S2, after each issuing of a carbon sink certificate, generating a first new block in the first block chain, storing the carbon sink certificate into the first new block, and finally broadcasting and transmitting the first new block to other block chain nodes.
In the step S2, the first blockchain is used to record all carbon sink certificates issued by the tamper-resistant record, i.e. record the blockchain as a carbon sink certificate. Because blockchain is a distributed ledger technique (Blockchain technology, also called a distributed ledger technique), and is characterized by decentralization, disclosure and transparency, so that everybody can participate in database records, in a narrow sense, blockchain is a chain data structure formed by combining data blocks in a sequential manner according to time sequence, and is a distributed ledger which is guaranteed to be untouched and untouched in a cryptographic manner, in a broad sense, blockchain technique is a brand-new distributed infrastructure and calculation manner, which uses the blockchain data structure to verify and store data, uses a distributed node consensus algorithm to generate and update data, uses a cryptographic manner to ensure the security of data transmission and access, and uses an intelligent contract composed of automated script codes to program and operate data, so that the existing blockchain technique can be adopted to upload the carbon certificate, thereby ensuring the high reliability of the carbon certificate by using the decentralization and untouchable characteristics of the blockchain.
S3, acquiring operation data of the carbon neutral and accounting period of the carbon emission purifying enterprises.
In the step S3, the carbon-lean enterprises may be, but not limited to, exemplified by an automobile production factory and the like. The carbon neutralization accounting period may be, but is not limited to, in units of days, weeks, months, quarters, or years, etc., such as to obtain operational data within a quarter. The operation data may include, but is not limited to, electricity consumption, oil consumption, etc., and thus may be collected by a conventional monitoring device such as an ammeter.
S4, recognizing carbon emission according to the operation data, and generating a carbon neutralization order for the net carbon emission enterprise according to a carbon emission recognition result, wherein the carbon neutralization order comprises, but is not limited to, recognized carbon emission and the like.
In the step S4, the specific identification manner of the carbon emission is also an existing manner, for example, a conversion formula based on the electricity consumption and the carbon emission. The carbon neutralization order is a task order which requires the clean carbon emission enterprise to counteract the carbon emission amount by purchasing a carbon sink certificate, and the clean carbon emission enterprise can be identified to realize carbon neutralization in the carbon neutralization accounting period only after the task order is responded and processed, so that production can be continued, and otherwise, production stopping may be required. In further detail, the carbon neutralization order also includes, but is not limited to, an order unique number, a generation time stamp, and a business unique number of the net carbon emission business, etc.
S5, searching all carbon sink certificates existing in the first blockchain and not existing in the second blockchain from the first blockchain and the second blockchain, wherein the blocks in the second blockchain are used for storing a pair of processed carbon neutralization orders and used carbon sink certificate combinations, and the used carbon sink certificate combinations comprise at least one carbon sink certificate used for carbon neutralization of the processed carbon neutralization orders.
In the step S5, the second blockchain is used to tamper-resistant record all processed carbon neutralization orders and all used carbon sink certificate combinations, i.e. as a carbon neutralization record blockchain. Whereby if a carbon sink certificate is present in the first blockchain and not in the second blockchain, it indicates that the carbon sink certificate is not used for carbon neutralization and may be sold to the net carbon emission enterprise, i.e., the all carbon sink certificates are all available certificates that may be sold to the net carbon emission enterprise. In order to encourage the clean carbon sink enterprises to actively sell the owned carbon sink certificates, and prevent the occurrence of the stock curiosity phenomenon, preferably, when the carbon sink certificates further include an issuing time stamp, the interval time from the issuing time stamp of each carbon sink certificate in all the carbon sink certificates to the current moment is less than or equal to a preset time, that is, if the interval time is longer than the preset time (for example, 1 year), the corresponding carbon sink certificate is not used for carbon neutralization and is not usable.
S6, determining M available certificate combinations according to all carbon sink certificates, wherein the available certificate combinations comprise at least one carbon sink certificate which belongs to all carbon sink certificates and has a total carbon sink amount greater than or equal to the carbon emission amount in the carbon and the order, and M represents a positive integer.
In the step S6, each of the M available certificate combinations is at least one carbon sink certificate suitable for counteracting the above-mentioned carbon emission amount, so as to be selected by the clean carbon emission enterprise. Preferably, in order to quickly determine the available certificate combinations, M available certificate combinations are determined according to all the carbon sink certificates, including but not limited to the following steps S61-S63: s61, regarding each carbon sink certificate in all the carbon sink certificates, if the corresponding carbon sink amount is larger than or equal to the carbon emission amount in the carbon neutralization order, using the corresponding carbon sink certificate as an available certificate combination; s62, when at least two carbon sink certificates with carbon sink quantity smaller than carbon emission quantity in the carbon neutralization order exist in all the carbon sink certificates, determining at least one carbon sink certificate combination according to the at least two carbon sink certificates; s63, regarding each carbon sink certificate combination in the at least one carbon sink certificate combination, if the corresponding total carbon sink amount is greater than or equal to the carbon emission amount in the carbon neutralization order, using the corresponding carbon sink certificate combination as an available certificate combination.
S7, acquiring a carbon sink certificate selling policy set by the carbon sink enterprise, and determining selling prices of all available certificate combinations in the M available certificate combinations according to the carbon sink certificate selling policy.
In the step S7, the carbon sink certificate selling policy may be specifically average pricing (for example, 10 yuan per unit carbon sink), or may be step pricing (for example, when the carbon sink certificate has a carbon sink higher than a certain value, lower average pricing is adopted), or the like. In addition, when a certain available certificate combination includes more than two carbon sink certificates and the more than two carbon sink certificates belong to different net carbon sink enterprises (i.e. the unique numbers of the enterprises in the more than two carbon sink certificates are different), the total selling price of the available certificate combination can be obtained through a conventional calculation mode according to the carbon sink certificate selling policies set by the different net carbon sink enterprises.
S8, pushing the carbon neutralization order, the top N available certificate combinations which are arranged in the order from low to high according to the selling price and the selling price of the top N available certificate combinations to the carbon emission purifying enterprise so that the carbon emission purifying enterprise can purchase one available certificate combination from the top N available certificate combinations to respond to the carbon neutralization order, wherein N represents a positive integer less than or equal to M.
In the step S8, N may be exemplified by 5. In order to realize the function of purchasing proper carbon sink certificates by proxy, preferably, when the net carbon emission enterprise is provided with a pre-charging account, the top N available certificate combinations obtained by arranging the carbon neutralization orders and the selling prices of the top N available certificate combinations in order from low to high are pushed to the net carbon emission enterprise, including but not limited to the following steps S81-S84.
S81, selecting an available certificate combination with the lowest selling price from the M available certificate combinations as a target certificate combination according to selling prices of all available certificate combinations in the M available certificate combinations.
In the step S81, if there are more than two available certificate combinations with the lowest selling price, the available certificate combination with the largest total carbon sink (i.e., the available certificate combination with the highest cost performance) may be further selected from the more than two available certificate combinations as the target certificate combination.
S82, using the current fund balance of the pre-charging account to automatically purchase the target certificate combination for the carbon emission enterprise.
In the step S82, the specific purchase processing mode is an existing conventional automatic deduction mode (a certain proportion of commissions can be allowed to be charged).
S83, if the target certificate combination is successfully purchased for the carbon emission enterprise, a second new block is generated in the second blockchain, the carbon neutralization order and the target certificate combination are used as a pair of processed carbon neutralization order and used carbon sink certificate combination to be stored in the second new block, and finally the second new block is broadcast and transmitted to other blockchain nodes.
In the step S83, if the purchase is successful, it indicates that the carbon neutralization has been automatically achieved by the carbon-emission enterprise within the carbon neutralization accounting period, and the high reliability of the combination of the processed carbon-neutralization order and the used carbon-sink certificate can be ensured by the uplink of the combination of the carbon-neutralization order and the target certificate, and the history backtracking can be facilitated.
S84, if the target certificate combination is not successfully purchased for the carbon emission enterprise, pushing the carbon neutralization order, the first N available certificate combinations obtained by arranging the carbon neutralization order in a low-to-high order according to the selling price and the selling price of the first N available certificate combinations to the carbon emission enterprise, wherein N represents a positive integer less than or equal to M.
In the step S84, if the purchase is unsuccessful, the main reason may be that the current balance of funds has insufficient payment, so as to prompt the carbon emission purifier to recharge in time, preferably, when the target certificate combination is not successfully purchased for the carbon emission purifier due to the insufficient payment of the current balance of funds, the method further includes: and sending a recharging reminding message to the carbon emission purifying enterprise.
After the step S8, the net carbon emission corporation may purchase one available certificate combination from the first N available certificate combinations according to its own consideration, considering that there is dissatisfaction in recommendation or that some of the top N available certificate combinations have become unavailable (e.g., expire or are purchased by other net carbon emission enterprises) due to purchase delay, in order to refresh recommended content in time, after pushing the carbon neutralization order and the top N available certificate combinations and the selling prices of the top N available certificate combinations in order from low to high to the net carbon emission corporation, the method further includes, but is not limited to: when a request for refreshing available certificates from the net carbon emission corporation is received or a part of carbon sink certificates in the first N available certificate combinations are found to be unavailable, a new first N available certificate combinations which are arranged in a low-to-high order according to the first blockchain, the second blockchain and the carbon sink certificate selling strategy are determined, and then the new first N available certificate combinations and the selling prices of the new first N available certificate combinations are pushed to the net carbon emission corporation again, so that the net carbon emission corporation can select one available certificate combination from the new first N available certificate combinations to respond to the carbon neutralization order. The aforementioned available certificate refresh request may be derived from feedback triggered by the net carbon emission enterprise when recommendation is unsatisfactory; the partial carbon sink certificate may be found to have become unavailable when the second blockchain is found to expire or be uplink according to an issue timestamp. In addition, the above-mentioned steps of re-executing the steps S5 to S8 are performed again, and specific processes are not repeated here, so that new N available certificate combinations obtained by arranging the first blockchain, the second blockchain and the carbon sink certificate selling policy in order from low to high selling prices are determined.
S9, if the clean carbon emission enterprise finds that a certain available certificate combination in the first N available certificate combinations is purchased before the processing deadline, generating a second new block in the second blockchain, storing the carbon neutralization order and the certain available certificate combination into the second new block as a pair of processed carbon neutralization orders and used carbon sink certificate combinations, and finally broadcasting and transmitting the second new block to other blockchain nodes.
In the step S9, the processing deadline may be, but is not limited to, a plurality of working days or natural days later, for example, 3 working days later. If the clean carbon emission enterprise has purchased a certain available certificate combination of the first N available certificate combinations (the specific purchasing mode is an existing transaction mode), it is indicated that the clean carbon emission enterprise has achieved carbon neutralization during the carbon neutralization accounting period, and the high reliability of the processed carbon neutralization order and the used carbon collection certificate combination can be ensured by uplink the carbon neutralization order and the certain available certificate combination, and history backtracking can be facilitated.
S10, if the net carbon emission enterprise is found that any available certificate combination which is pushed is not purchased when the processing deadline is reached, a forced production stopping notification message is sent to the net carbon emission enterprise.
In the step S10, the triggering mechanism of the forced outage notification message is a carbon neutralization control measure for prompting the clean carbon emission enterprise to purchase a suitable carbon sink certificate in time to offset the carbon emission. Considering that the net carbon emission enterprise may historically purchase excess carbon sink, in order to promote the fair rationality of sending the forced outage notification message, it is preferable to send a forced outage notification message to the net carbon emission enterprise if it is found that the net carbon emission enterprise does not purchase any available certificate combination for pushing when the process deadline is reached, including but not limited to the following steps S101-S104: s101, if any available certificate combination which is pushed is not purchased by the clean carbon emission enterprise when the treatment deadline is reached, all processed carbon neutralization orders and all used carbon sink certificate combinations of the clean carbon emission enterprise are searched from the second blockchain, wherein all processed carbon neutralization orders are in one-to-one correspondence with all used carbon sink certificate combinations; s102, calculating to obtain a difference value between the total carbon sink amount in all the used carbon sink certificate combinations and the total carbon emission amount in all the processed carbon neutralization orders and the carbon emission amount in the carbon neutralization orders; s103, judging whether the difference value is smaller than or equal to a preset threshold value; and S104, if so, sending a forced shutdown notification message to the carbon emission purifying enterprise. The predetermined threshold is specifically zero or a negative number. In addition, if the difference is determined to be greater than the preset threshold, a forced shutdown notification message may be sent to the carbon-purifying emission enterprise temporarily, but a shutdown early warning message may be sent, so that the carbon-purifying emission enterprise takes reasonable measures to avoid being forced shutdown.
The new scheme for realizing pushing and purchasing of the proper carbon sequestration certificate based on the blockchain technology is provided based on the carbon neutralization management method described in the steps S1-S10, namely, on one hand, the carbon sequestration amount in a unit period is periodically determined for a clean carbon sequestration enterprise, the carbon sequestration certificate is issued for the clean carbon sequestration enterprise according to the carbon sequestration amount determination result, and the carbon sequestration certificate is linked, on the other hand, the carbon emission amount is determined according to the operation data of the clean carbon sequestration enterprise in the carbon neutralization accounting period, and the carbon neutralization order is generated for the clean carbon sequestration enterprise according to the carbon emission amount determination result, then, based on all the available carbon sequestration certificates searched from the carbon sequestration certificate record blockchain and the carbon sequestration record blockchain, the available certificate combination suitable for canceling the determined carbon emission amount is automatically pushed for purchase by the clean carbon sequestration enterprise, and finally, if the purchase is not scheduled, forced outage is notified, so that the high reliability of the carbon sequestration certificate and the historical carbon sequestration can be ensured, and the clean carbon sequestration enterprise can be further prompted to cancel the carbon sequestration certificate in time, and the proper carbon sequestration certificate can be popularized and the proper carbon sequestration certificate can be applied conveniently.
