摘要:

目前我国碳排放交易主要依靠中心化系统来管理交易任务,缺乏公开透明的交易信息、行政干预多,致使碳交易市场不活跃。为加强我国碳市场的活力,助力推进碳达峰、碳中和目标的实现,提出了一种两层级的混合区块链碳排放交易框架。介绍了碳市场发展现状和相关政策,总结了目前我国碳排放市场存在的问题,对碳交易机制进行概述,针对我国碳排放市场存在的问题,提出了基于区块链技术的碳排放交易框架。该框架包含公共区块链和联盟区块链,其中公共区块链中进行政府碳配额的分配,且透明、可追踪;联盟区块链中仅共享碳排放数据,以保护某些企业的隐私数据。另外,该框架基于Polkadot协议实现公共区块链与联盟区块链之间的信息传输,提出的碳排放交易框架,可以减少系统运行成本,提高交易的效率和信息透明度,为加快碳交易市场化提供参考和借鉴。

Abstract:

At present,carbon emissions trading mainly relies on a centralized system to manage the transactions.Due to the lack of transparent trading information and excessive administrative intervention,the carbon emissions trading market is inactive.In order to boost the vitality of carbon market and advance the realization of carbon peaking and carbon neutrality in China,a carbon emissions trading framework based on a two-level hybrid blockchain network is built. Firstly, the development status and relevant policies of China’s carbon market are introduced,and the existing problems in the market are summarized.Then,the carbon trading mechanism is expounded. Finally,a carbon emission trading framework based on blockchain technology is proposed to solve the problems.The framework consists of public blockchain and consortium blockchain.Carbon allowances are allocated in public blockchain,which is transparent and traceable.Only carbon emissions data can be shared in consortium blockchain to protect the private data of enterprises.In addition,the framework can transit information between public blockchain and consortium blockchain based on Polkadot protocol.The carbon emissions trading framework can reduce the system operation cost,and improve the trading efficiency and information transparency,which provides a reference for accelerating the marketization of carbon trading.

Key words: carbon peaking, carbon neutrality, carbon trading, hybrid blockchain network, public blockchain, consortium blockchain, Polkadot protocol
