Carbon emission permit and green certificate combined transaction system based on block chain

Abstract

The invention relates to the technical field of information, in particular to a block chain-based carbon emission permit and green certificate combined transaction system, which comprises an access subsystem, a filling subsystem, a matching subsystem and a settlement subsystem, and is characterized in that an enterprise transfers a carbon emission permit and / or a green certificate into the access subsystem, transfers a corresponding number of certificates into an enterprise virtual account, and checks the corresponding number of certificates; the filling subsystem receives a purchase filling order and a sale filling order of an enterprise, the filling subsystem extracts hash values of the purchase filling order and the sale filling order and uploads the hash values to a block chain for storage, the matching subsystem generates a lineation unit price, so that the number of transaction certificates under the lineation unit price is maximum, and the settlement subsystem performs fund settlement according to the transaction purchase filling order and the sale filling order. And the corresponding token is transferred to the virtual account of the corresponding transaction purchasing enterprise, and the enterprise exchanges the token into carbon emission permissions or green certificates with the consistent number through the access subsystem. The method has the substantive effects that the trading volume can be effectively improved, and the loss caused by the fact that an enterprise cannot accurately grasp the market law is reduced.

Description

Technical field

[0001] The present invention relates to the field of information technology, specifically to a blockchain-based carbon emissions joint trading system with green certificates. Background

[0002] Carbon emission rights refer to the right of enterprises to emit carbon dioxide into the atmosphere. Carbon emissions have become a valuable asset that can be exchanged in the market as a commodity. Companies that are struggling to reduce emissions can buy carbon rights from companies that are easy to reduce emissions, and the latter complete the task of reducing emissions for the former, and also get the benefits. The way companies obtain carbon emission rights include initial free distribution and market transactions. The initial free allocation refers to the carbon emission quota allocated by the competent department to the emission control enterprise free of charge according to the emission control target and the production situation of the emission control enterprise...
