Description

Technical Field

[0002] Carbon verification refers to the process of verifying the greenhouse gas emission reports submitted by carbon emission entities participating in carbon emission trading to ensure the validity of the emission data submitted. The data from carbon verification is not only a crucial basis for supervising corporate carbon emissions and subsequent carbon reduction, but also essential foundational data required for the country to achieve its dual-carbon goals.

[0003] In existing technologies, carbon emission data verification typically requires carbon emitting entities to collect relevant data and send it to data verification personnel for manual verification of its accuracy and reliability. However, research has revealed that due to the uncontrollable nature of individual behavior, the original data may be altered or omitted during the data transmission and manual verification processes, making accurate and effective verification impossible and resulting in inaccurate and unreliable verification results.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0063] Example 1

[0064] To facilitate understanding of this application, the following is combined with... Figure 1 The flowchart of the carbon emission data verification method provided in Embodiment 1 of the present invention illustrates the content of Embodiment 1 in detail.

[0065] See Figure 1 As shown, Figure 1 The flowchart illustrates a carbon emission data verification method according to Embodiment 1 of the present invention, which is applied to a carbon emission data verification system. The system includes a storage terminal, a verification terminal, and a management terminal. The storage terminal and the verification terminal are capable of communication. The method includes steps S101 to S103:

[0066] S101: The evidence storage terminal performs hash processing on the carbon emission data to obtain the evidence storage hash value, uploads the carbon emission data to the blockchain, and sends the evidence storage hash value to the management terminal.

[0067] Specifically, carbon emission data includes energy data and carbon monitoring data. When hashing carbon emission data, the following methods can be used: Method 1: Divide the carbon emission data into several blocks of equal or unequal length. Perform bitwise operations, shift operations, modulo operations, XOR operations, etc., on each message block to obtain a message digest. Then combine all message digests or perform further operations to obtain the final hash value. Method 2: Select an appropriate hash function based on the type of carbon emission data, such as MD5, SHA-1, SHA-256, etc.; preprocess the carbon emission data according to the requirements of the hash function, such as padding and grouping; and calculate the evidence hash value using the hash function after processing the carbon emission data.

[0068] Carbon emission data and its corresponding hash function are uploaded to various blockchain nodes for consensus and synchronization, and the evidence hash value is sent to the management terminal for storage. The management terminal can also encrypt the evidence hash value to prevent it from being cracked or tampered with.

[0069] S102: The verification terminal extracts the carbon emission data from the blockchain, performs hash calculation on the extracted carbon emission data to obtain a verification hash value, and sends the verification hash value to the management terminal.

[0070] Specifically, the verification end randomly selects a node in the blockchain, extracts carbon emission data and its corresponding hash function from that node, uses the hash function to perform hash calculation on the extracted carbon emission data to obtain the verification hash value, and sends the verification hash value to the managed end.

[0071] S103: The management terminal verifies the carbon emission data based on the evidence storage hash value and the verification hash value.

[0072] Specifically, the management end matches the evidence storage hash value and the verification hash value, and checks whether the carbon emission data has been tampered with based on the matching result. If the management end has encrypted the evidence storage hash value, the encrypted evidence storage hash value is decrypted before executing step S103.

[0073] In one feasible implementation plan, see Figure 2 As shown, Figure 2 The flowchart illustrates a method for calculating a notarization hash value according to Embodiment 1 of the present invention, wherein the step of hashing carbon emission data to obtain a notarization hash value includes steps S201 to S203:

[0074] S201: Perform hash calculations on each carbon emission data to obtain the first hash value corresponding to each carbon emission data.

[0075] S202: Generate the first hash chain based on the first hash value corresponding to each carbon emission data.

[0076] S203: Perform hash calculation on the first hash chain to obtain the evidence storage hash value.

[0077] Specifically, each carbon emission data point is hashed to obtain a first hash value. The first hash values ​​are then chained together using a cryptographic hash function to form a first hash chain. Each data block in the first hash chain contains the hash value of the previous data block. Finally, the first hash chain is hashed to obtain the evidence storage hash value.

[0078] In one feasible implementation, before uploading the carbon emission data to the blockchain at the evidence storage terminal, the method further includes:

[0079] The carbon emission data is desensitized.

[0080] Specifically, a sensitive replacement database is pre-set at the evidence storage terminal. This database stores sensitive words and their replacement words. Before uploading carbon emission data to the blockchain at the evidence storage terminal, the carbon emission data is matched against the sensitive words in the sensitive replacement database. If the carbon emission data contains sensitive words, the corresponding replacement words are used to replace those sensitive words, thus achieving desensitization.

[0081] In one feasible implementation, the blockchain includes several consensus nodes and several synchronization nodes.

[0082] Specifically, the deployment of consensus nodes and synchronization nodes can be configured according to actual needs. In practical applications, based on existing business applications and expansion requirements, more than 10 blockchain nodes are deployed, using the PBFT consensus algorithm, of which 5 are consensus nodes and the rest are synchronization nodes.

[0083] Consensus Nodes: A China National Petroleum Corporation (CNPC) carbon asset chain will be created through a Blockchain as a Service (BaaS) platform. Five organizations (CNPC Quality, Health, Safety and Environmental Protection Department, CNPC Greenhouse Gas Verification and Accounting Center, CNPC Carbon Trading Service Center, Energy Company, and National Oil & Gas Pipeline Group Co., Ltd.) will each have five consensus nodes, possessing the full blockchain data. The consensus nodes will be deployed as follows: one for CNPC Quality, Health, Safety and Environmental Protection Department, one for CNPC Greenhouse Gas Verification and Accounting Center, one for the Group's Carbon Trading Service Center, one for the Energy Company, and one for National Oil & Gas Pipeline Group Co., Ltd., forming a disaster-tolerant blockchain network. Even if one blockchain node fails, the network will continue to operate normally. This blockchain network can be flexibly expanded according to business needs, with nodes dynamically added or removed, and different permissions assigned to nodes based on business requirements.

[0084] Synchronization Nodes: Five organizations are created, namely carbon trading market units, carbon emitting enterprises, the Ministry of Ecology and Environment, the National Carbon Emission Rights Registration and Settlement System, and the Shanghai Energy and Environment Exchange. Each of these five synchronization nodes possesses the full amount of blockchain data and only synchronizes data without reaching consensus.

[0085] See Figure 3 As shown, Figure 3 The flowchart of a ledger data update method provided in Embodiment 1 of the present invention is shown. After the carbon emission data is uploaded to the blockchain at the evidence storage terminal, the method further includes steps S301 to S302:

[0086] S301: Each consensus node reaches a consensus on the carbon emission data and generates ledger data based on the consensus result.

[0087] Specifically, consensus nodes sort all operations by executing the consensus protocol, then execute the operations in the order of consensus, calculate the new state, thereby reaching consensus, and record each operation and state to obtain ledger data.

[0088] S302: Each synchronization node updates the ledger data.

[0089] Specifically, synchronization nodes update the ledger by receiving and applying consensus messages from consensus nodes.

[0090] In one feasible implementation plan, see Figure 4 As shown, Figure 4 The flowchart of a verification hash value calculation method provided in Embodiment 1 of the present invention is shown, wherein the step of performing hash calculation on the extracted carbon emission data to obtain a verification hash value includes steps S401 to S403:

[0091] S401: Perform hash calculations on the extracted carbon emission data to obtain the second hash value corresponding to each carbon emission data.

[0092] S402: Generate a second hash chain based on the second hash value corresponding to each carbon emission data.

[0093] S403: Perform a hash calculation on the second hash chain to obtain the verification hash value.

[0094] Specifically, each carbon emission data point is hashed to obtain a second hash value. These second hash values ​​are then chained together using a cryptographic hash function to form a second hash chain. Each data block in the second hash chain contains the hash value of the previous data block. Finally, the second hash chain is hashed to obtain a verification hash value.

[0095] In one feasible implementation plan, see Figure 5 As shown, Figure 5 The flowchart illustrates a specific carbon emission data verification method provided in Embodiment 1 of the present invention, wherein the verification of the carbon emission data based on the evidence hash value and the verification hash value includes steps S501 to S503:

[0096] S501: Determine whether the evidence storage hash value is the same as the verification hash value.

[0097] S502: If the evidence storage hash value is the same as the verification hash value, then the verification result of the carbon emission data is determined to be valid.

[0098] Specifically, if the evidence hash value is the same as the verification hash value, it means that the data has not been tampered with. The verification result of the carbon emission data will be determined as valid, and the verification result will be displayed in text or broadcast by voice.

[0099] S503: If the evidence storage hash value is different from the verification hash value, the verification result of the carbon emission data shall be determined as invalid.

[0100] Specifically, if the evidence hash value and the verification hash value are different, it means that the data has been tampered with. In this case, the verification result of the carbon emission data will be determined to be invalid, and the verification result will be displayed in text or broadcast by voice.

[0101] In one feasible implementation, the carbon emission data includes information on energy types, fuel consumption, energy purchases, energy inventory, product output, and carbon emission monitoring data.

[0102] Specifically, in practical applications, in accordance with the requirements of greenhouse gas emission accounting methods and reporting guidelines, the following data are verified, including but not limited to: the source and value of carbon dioxide fuel combustion emission data, the source and value of process emission data, the source and value of purchased electricity and heat emission data, and the source and value of special emission data. Before verification, it is confirmed that the energy consumption data, inventory data, and process emission data, after being calculated using emission factors, do not differ significantly from the collected carbon emission data, thus ensuring the authenticity of the data before it is uploaded to the blockchain. By uploading enterprise energy purchase, consumption, and inventory data to the blockchain in real time, and by uploading carbon emission monitoring data to the blockchain in real time, a logically consistent and credible data record is formed. In future carbon emission verification processes, the logically consistent original energy purchase, consumption, and inventory data, along with the carbon emission data, ensure the authenticity of the data before it is uploaded to the blockchain. Blockchain technology ensures the validity of the data after it is uploaded to the blockchain, thereby improving the credibility of carbon asset data in collaborative carbon asset management, enhancing the efficiency of collaborative carbon asset operations among upstream and downstream enterprises, and reducing carbon asset operating costs.
