Description

Device and method for providing blockchain-based greenhouse gas emissions trading service {APPARATUS AND METHOD FOR PROVIDING BLOCKCHAIN NETWORK-BASED GREENHOUSE GAS EMISSION TRADING SERVICE}

This disclosure generally relates to a credit trading system that provides trading services for greenhouse gas emissions rights based on a blockchain network. More specifically, the present disclosure recommends customized greenhouse gas reduction certificates for credit-demanding companies performing greenhouse gas emission projects and provides reduction feedback information to credit supply companies performing greenhouse gas reduction projects, thereby providing a voluntary carbon market ( It concerns devices and methods for efficiently operating the voluntary carbon market (VCM).

Carbon emissions trading refers to a transaction in which companies in each country that failed to reduce greenhouse gas emissions within a set period buy rights in exchange for money from businesses that have surplus emissions or have contributed to the environment, such as by creating forests. Countries that have joined the Kyoto Protocol must reduce carbon dioxide emissions to their respective targets, and countries or companies that fail to do so must purchase carbon credits from outside. Companies in member countries are subject to certain standards when greenhouse gas emissions are allocated, and companies with large greenhouse gas emissions are required to reduce greenhouse gas emissions through technology development such as energy saving or to own surplus emission rights due to low emissions. The issue must be resolved by purchasing the rights from . In other words, the Kyoto Protocol obliges companies to curb carbon emissions and allows companies that reduce carbon emissions to make economic gains by selling the reductions to other companies.

In response to greenhouse gas emission regulations, technology for services that allow companies to trade greenhouse gas emissions rights is being proposed. For example, activities using transportation that does not generate carbon, such as bicycles, are recognized as carbon reduction activities, and various technologies have been proposed to compensate for the resulting carbon credits.

The voluntary carbon market refers to a private carbon market that allows various organizations, such as individuals, businesses, governments, and non-profit organizations, to voluntarily participate in carbon reduction projects and create and trade carbon credits. The regulated carbon market had the problem of not being able to create new quotas as participants were limited to trading quotas according to national and regional systems, and it was difficult to attract the interest of those who were not eligible to participate, while the voluntary carbon market had problems. To overcome the limitations of the regulated carbon market, it is operated as a market-centered autonomous structure.

In the voluntary carbon market, security is very important in the certification and trading of carbon reductions. Accordingly, attempts are being made to incorporate blockchain network technology into the voluntary carbon market. Blockchain technology refers to a distributed data storage technology that stores data in blocks, connects them in a chain, and copies and stores them on multiple computers simultaneously. Blockchain technology has the advantage that transaction details are disclosed to all participants in the transaction, and information can be shared and collated between participants whenever a transaction occurs, preventing data forgery or alteration. Due to the above advantages, smart contracts, credit, etc. It can be used for transactions.

The conventional greenhouse gas emissions trading system performed the function of intermediary between credit supply companies carrying out reduction projects and credit demand companies carrying out emission projects. Here, credit supply companies and credit demand companies only traded based on the total amount of carbon emissions, and as a result, credit demand companies had no choice but to purchase emission permits regardless of corporate identity, and credit supply companies had to carry out reduction projects more efficiently. There was a problem where information could not be confirmed.

The above-mentioned technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and does not necessarily indicate known technology disclosed to the general public before filing the application for the present invention.
