Description

Carbon trading system and method

The present invention relates to a trading system and method, and more particularly relates to a carbon rights trading system and method using blockchain technology.

Human activities increase the amount of greenhouse gases in the atmosphere. The emissions produced by burning fossil fuels, water vapor, carbon dioxide, methane, etc., are absorbed and retained by infrared radiation, leading to an increase in global surface temperature, aggravating the greenhouse effect, and causing global warming . In order to solve this problem, the United Nations formulated the Framework Convention on Climate Change to control the emission of greenhouse gases and prevent the earth's temperature from rising and affecting the ecology and environment.

Carbon trading is the “Kyoto Protocol” to promote the global reduction of greenhouse gas emissions, adopting a market mechanism, and establishes the “United Nations Framework Convention on Climate Change” (The United Nations Framework Convention on Climate Change, UNFCCC) as a basis for greenhouse gas emission rights (reductions). Displacement) transaction. Carbon dioxide (CO ₂ ), methane (CH ₄ ), nitrous oxide (N ₂ O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF6) are the 6 types included in the Convention Greenhouse gases that require reductions. Greenhouse gas trading is often measured in units of carbon dioxide equivalent per ton (tCO2e), collectively referred to as "carbon trading." Its trading market is called the "Carbon Market" (Carbon Market).

Carbon trading is divided into two types: the first is allowance-based transactions: refers to the trading of emission reduction units generated under total control, such as the European Union’s EU Emissions Trading System "EU Emissions" "Quota" (European Union Allowances, EUAs) Transactions are mainly transactions of excess emission reductions between countries that are reduced by the Kyoto Protocol, usually spot transactions. The second type is project-based transactions: refers to the transactions of emission reduction units resulting from the implementation of emission reduction projects, such as "emission reduction warrants" under the clean development mechanism, and "emission reduction units under the joint implementation mechanism" "It's mainly the emission reduction trading generated through the country-to-country cooperation emission reduction plan, which is usually pre-sold in the form of futures. However, in terms of actual operation, it is questionable whether some developed countries can truly achieve the goals of energy conservation and carbon reduction. Moreover, whether the carbon emission trading system can truly achieve the goal of energy saving and carbon reduction, or is only regarded as a tool for monopoly and wealth accumulation by traders, is also questionable.

Blockchain is a shared encrypted general ledger technology established by a computer network. Every member of the network can obtain general ledger data, and there is no so-called single authorization mechanism. If blockchain can be applied to carbon rights trading, it can directly connect producers and consumers, and make the system operation more transparent. However, most of the current blockchains use digital currencies as the transaction vouchers for carbon rights transactions, rather than direct carbon rights transactions.

In view of the above problems, it is necessary to propose a new carbon trading system and method to solve the above problems.

The main purpose of the present invention is to propose a carbon rights trading system, so that both the supply side and the demand side on the network node can obtain general ledger data, and there is no so-called single authorization mechanism; and provide both parties with real-time carbon rights. The price makes a balance between the supply side and the demand side.

Such modifications and changes will be included in the scope of the present invention.

Please refer to Figure 1, which is a schematic structural diagram of the first embodiment of the carbon rights trading system 100 of the present invention. A carbon rights trading system 100 includes: at least one carbon rights supply terminal 110, which provides one carbon right; and at least one carbon rights demand terminal 120, which obtains the carbon rights provided by the at least one carbon right supply terminal; The supply end and the at least one carbon rights demand end form an Internet connection 140 with a plurality of nodes connected to each other in a network.

In the carbon rights trading system 100, "carbon rights" can be quantified as virtual digital assets, such as virtual electronic currency or points. Therefore, the abstract "carbon rights" will be Quantified virtual digital assets are transferred.

The at least one carbon rights supply terminal 110 and the at least one carbon rights demand terminal 120 are connected to each other by a network connection 142 (indicated by a dotted line in Figure 1) to form an Internet path 140 with a node 144 . That is, the at least one carbon rights supply end 110 and the carbon rights demand ends 120 have their own nodes 144 in the Internet road 140.

The at least one carbon rights supply end 110 and the at least one carbon rights demand end 120 include at least one of the following: a server, a cloud data center, a computer, and a workstation. Government agencies, such as the Environmental Protection Agency, or financial institutions, such as banks or insurance companies, can also link their information processing systems to the carbon rights trading system 100 as a link between the at least one carbon rights supply end 110 and the carbon rights demand ends 120 One side. In the carbon rights trading system 100, any of the at least one carbon rights supply terminal 110 and the at least one carbon rights demand terminal 120 connected to the node 144 of the Internet road 140 can monitor carbon rights trading records and market price fluctuations at any time , Transaction price and the operation of controlling the transfer of carbon rights.

The Internet channel 140 includes technologies such as transmission access, network exchange, mobile communication, wireless communication, optical communication, satellite communication, support management, and private network communication. Preferably, the Internet channel 140 can be a wired network or wireless Network, including: third-generation mobile communications (3G), fourth-generation mobile communications (4G), fifth-generation mobile communications (5G), Worldwide Interoperability for Microwave Access (WiMAX), network protocols Television (Internet Protocol Television, IPTV), Next Generation Network (NGN), etc. In the present invention, the Internet path 140 does not mean an independently formed network system, but means that the nodes in the Internet path 140 constitute a network that is interconnected and communicates with each other.

Wherein, when the at least one carbon rights supply end proposes a carbon rights supply amount and a message is sent to each node of the Internet road, and the at least one carbon rights demand end proposes a carbon rights demand amount and a message is sent to the Internet When each node of the road, a certain node in the Internet road is based on a zone The block chain model forms a smart contract and sends it to every node on the Internet. The information of the carbon rights supply further includes the type of carbon rights, the expected price, etc., and the information of the carbon rights demand further includes the type of carbon rights, the expected price, etc.

Therefore, for the demand side, we can see information about the supply, price, type, and quantity of various carbon rights sold on the supply side. For the supply side, you can also see the various carbon rights demand, prices, and types set by the demand side. The blockchain model refers to a way of using programs or software to execute. Therefore, the carbon rights trading system 100 integrates the at least one carbon rights supply end 110 and the at least one carbon rights demand end 130 into a single blockchain trading system. Therefore, the carbon rights trading system 100 does not need to interact with government agencies or financial institutions. Institutional links can be independent trading operations, trading to obtain carbon rights.

The at least one carbon rights supply terminal 110 of the present invention has renewable energy power sources, such as solar power sources, wind power sources, biomass power sources, ocean current power sources, hydro power sources, fuel power sources, micro-turbine power sources, etc. , As a renewable energy source that can provide carbon rights. Therefore, the at least one carbon rights supply end 110 includes at least one renewable energy source. The renewable energy power generation source of the at least one carbon right supply end 110 is selected from one of the following: solar power generation, wind power generation, biomass power generation, ocean current power generation, hydroelectric power generation, fuel power generation, and micro-turbine power generation .

Of course, the at least one carbon right supplier 110 needs to first hand over the carbon right payment quota stipulated by the government to the competent authority. If there is a large carbon right quota before it can be sold, otherwise the carbon right trading system 100 will prohibit unsuccessful carbon rights. The at least one carbon right supply end 110 of the standard of the right amount is turned over to conduct carbon right trading.

Please refer to Figure 2, which is a schematic diagram of the at least one carbon rights supply terminal 110 of the present invention. The at least one carbon rights supply end 110 includes a demand storage element 112 and a supply end central processing element 114. The demand storage component 112 receives and stores the The information about the demand for carbon rights; the supply-side central processing component 114, when proposing the information about the supply of carbon rights to the Internet channel or receiving the information about the carbon rights demand from the Internet channel, will create a block-based A new block of the chain model is used to perform a proof of work and transmit the proof of work to each node in the Internet path.

The supply-side central processing unit 114 does not mean a single central processing unit, but can be a central processing unit composed of multiple central processing chips to meet the needs of a large number of calculations. In one embodiment, the supply-side central processing unit 114 is further electrically connected to a server 250. When the supply-side central processing unit 114 cannot process the actions of the blockchain model due to too much workload, the server The (server) 150 can assist the supply-side central processing element 114 as a processing element for higher-speed computing.

The at least one carbon right demand end 120 may be a greenhouse gas reduction credit account. Please refer to FIG. 3, which is a schematic diagram of the at least one carbon rights demand end 120 of the present invention. The at least one carbon rights demand end 120 includes a supply storage element 122 and a demand end central processing element 124. The supply storage component 122 stores the carbon rights supply information from the Internet road; the demand-side central processing component 124 sends the information about the carbon rights demand to the Internet road or receives the information from the Internet road When carbon rights supply information, a new block based on the blockchain model will be created to perform a proof of work, and the proof of work will be transmitted to every node in the Internet.

In the new block based on the blockchain model established by each node 144 formed by the at least one carbon rights supply end 110 and the at least one carbon rights demand end 120, a carbon rights transaction quota is proposed, which refers to By comparing the various carbon rights supply quantity, price, type, and quantity information sold on the supply side, and the various carbon rights demand quantity, price and type information set by the demand side, in the blockchain model Finally formed. And the new block includes the previous smart contract with timing, the header (the reference position of the previous block), and the random number used only once (nonce), get a hash function. After each node receives the new block, it confirms it and performs the proof-of-work algorithm.

The demand-side central processing unit 124 does not mean a single central processing unit, but can be a central processing unit composed of multiple central processing chips to meet the needs of a large number of calculations. In one embodiment, the demand-side central processing component 124 is further electrically connected to a server 250. When the demand-side central processing component 124 cannot process the actions of the blockchain model due to too much workload, the server The (server) 150 can assist the demand-side central processing element 124 as a processing element for higher-speed computing.

The blockchain model includes: an encryption process and a mining process. In the encryption process, use the carbon rights trading quota and a hash random number to form a hash function; in the mining process, a certain node in the Internet path solves the hash function to form the smart contract , And add a time mark to the smart contract to form a time-series smart contract.

After a certain node in the Internet road first solves the hash function, it forms a new smart contract with time series, and connects to the original blockchain of each node on the Internet road 140, and puts the new The time-series smart contract is transmitted to every node on the Internet 140.

It should be noted that a typical blockchain model is that each node on the Internet road 140 periodically broadcasts on the Internet road 140 for a period of time a new block that should be registered into a time-series smart contract. The latest verified smart contract with timing is placed after the last verified smart contract with timing.

The blockchain module is a shared encrypted ledger technology established by the network, and each node on the at least one carbon right supply end 110 and the carbon right demand ends 130 in the Internet 140 can obtain the supply end The central processing component 114 or the demand-side central processing component 124 forms the time-series smart contract based on the blockchain model. There is no so-called single authorization mechanism, so it can directly connect the supply side and the demand side in real time, allowing the carbon rights trading system 100 operations have become more transparent.

The record of the smart contract includes at least: the time when the smart contract was generated, the amount of carbon rights trading, and the price of carbon rights. It can also include: the record of carbon rights transactions that generated the smart contract, market price fluctuations, transaction prices, and carbon rights. Rights transfer operations, etc.

In the carbon rights trading system 100, since each node 144 of the carbon rights trading system 100 can store transaction record information on the demand side and the supply side, the carbon rights trading system 100 can generate carbon price warning information based on the transaction record information And establish a carbon market forecast model. The carbon rights trading system 100 can analyze the market fluctuations and status of carbon rights prices based on the transaction record information of many demand sides and many supply sides in the world, so as to generate carbon price warning information, and generate carbon rights markets based on statistical results. Forecast model.

The supply of carbon rights is mainly related to the electricity generated by renewable energy sources. Since the renewable energy power generation system is selected from one of the following: solar power generation, wind power generation, biomass power generation, ocean current power generation, hydropower generation, fuel power generation, micro-turbine power generation, and it is affected by the environment and climate. Therefore, the supply of carbon rights that can be provided at different times is not fixed. Therefore, in a space, the more electricity generated by renewable energy sources, the more electricity generated by the at least one carbon right supply end 110 can be generated by renewable energy sources, which can be produced by itself or purchased by other parties, then The more carbon rights can be provided.

When the supply of carbon rights is greater than the demand for carbon rights, the price of the carbon rights and a change amount show a negative value, and the change amount is the difference between the price of the carbon rights this time and the price of the carbon rights last time , And when the absolute value of the negative value is greater, the amount of change is greater; when the supply of carbon rights is less than the demand for carbon rights, one of the changes in the price of the carbon rights presents a positive value, and the amount of change is The difference between the price of the carbon rights this time and the price of the carbon rights last time, and the greater the positive value, the greater the amount of change.

The block chain module allows the at least one carbon right supply end 110 and the carbon right demand ends 130 to directly conduct peer-to-peer (P2P) transactions, so the at least one carbon right supply end 110 immediately receives the at least one carbon right demand End of the cost of 120. As a result, the carbon rights trading system 100 does not need to balance supply and demand Through government agencies or financial institutions, the processing time and cost of the intermediate process can be saved.

The carbon rights trading system 100 may restrict the use of carbon trading from the at least one carbon rights supply end 110 to the at least one carbon rights demand end 120 immediately. For example, it can be stipulated that after a predetermined period of time, the demand side and the supply side cannot use the carbon credits of certain specific sources as exchanges for the greenhouse gas reduction commitments of relevant laws and regulations, but this is not the limit if the purpose has been designated. For example, the carbon credits issued on the demand side and the supply side due to advance projects cannot be used for greenhouse gas reduction commitments in exchange for relevant regulations after three years unless they have been designated for use, such as environmental assessment credits, as payment Quota. The reason for this is that the current competent authority hopes that demand-side and supply-side companies can implement energy conservation and carbon reduction. Therefore, it is stipulated that the carbon credits obtained from previous projects cannot be used for the purpose of EIA offset every year, otherwise companies will be in the EIA The promised reduction will lose its due benefit.

The restriction can be recorded in the blockchain module, the supply-side central processing element 114 of the at least one carbon rights supply end 110, or the demand-side central processing element 124 of the at least one carbon rights demand end 120, so that every time During the transaction, this restriction is automatically implemented.

Please refer to Figure 4, which is a flowchart of an embodiment of the carbon rights trading method, which mainly uses the carbon rights trading system of the present invention. Please cooperate with Figure 1. The method in Figure 4 is used in a carbon rights trading system, including at least one carbon rights trading system 100, including: at least one carbon rights supply end 110 that provides one carbon rights; and at least one carbon rights demand end 120. Obtain the carbon rights provided by the at least one carbon rights supply end; the at least one carbon rights supply end and the at least one carbon rights demand end form an Internet connection 130 with a plurality of nodes.

The carbon rights trading method mainly includes the following steps: Step 1: The at least one carbon rights supply end and the at least one carbon rights demand end are connected to each other to form an Internet path with a plurality of nodes; step 2 : When the at least one carbon rights supply end proposes a carbon rights supply and a message is sent to each node of the Internet road, and the at least one carbon rights demand end proposes a carbon rights demand and a message transmission When sent to each node of the Internet road, a certain node on the Internet road forms a smart contract based on a blockchain model; Step 3: The smart contract is sent to each node of the Internet road.

Please refer to Fig. 5, which is a flowchart of a detailed embodiment of step 2 of the carbon rights trading method of the present invention. Step 2 further includes: Step 2-1: an encryption process, using a carbon rights trading quota, and a hash random number to form a hash function; and step 2-2: a mining process, a certain part of the Internet After solving the hash function, a node forms the smart contract, and adds a time mark to the smart contract to form a timing smart contract.

The record of the smart contract includes at least: the time when the smart contract was generated, the amount of carbon rights trading, and the price of carbon rights. It can also include: the record of carbon rights transactions that generated the smart contract, market price fluctuations, transaction prices, and carbon rights. Rights transfer operations, etc.

When the supply of carbon rights is greater than the demand for carbon rights, the price of the carbon rights and the amount of change present a negative value; when the supply of carbon rights is less than the demand for carbon rights, one of the prices of the carbon rights The amount of change presents a positive value.

In summary, the carbon rights trading system and method of the present invention have the following effects:

First, openness and transparency: Since the blockchain data of the carbon trading system can be opened to all supply and demand sides, any supply and demand side can query blockchain data and develop related applications through an open interface, so the entire system The message is highly transparent. Directly link the supply side and the demand side, making the operation of the carbon trading system more transparent.

Second, the record is accurate: In the blockchain, as long as outsiders cannot fully control more than half of the nodes, they cannot arbitrarily manipulate or modify the characteristics of network data, so cross-border exchanges can be prevented. Easy crime, domestic crime, and has the function of maintaining information and transaction security.
