The carbon market auction mechanism is an important policy tool for carbon pricing and a key mechanism that supports carbon emission neutralization,especially for China.A few systematic studies exist on China’s carbon market auction mechanism.This article focuses on the five auction mechanisms in Chinese pilot emission trading schemes(ETS),reviews the structures and bidding situation of the five-pilot auction mechanism,extracts the similarities,and analyzes their different features,such as auction mode,bidding scale,participants,pricing mode,auction frequency,and so on.This study conducts an in-depth analysis of the carbon allowance auction mechanism in the Guangdong pilot ETS of China,including its development and the evolution of the key elements,its operational effects,and related disputes.Finally,this study puts forward the trend forecast and suggestions for the Chinese allowance auction mechanism,such as the time window of launching national allowance auctions,the most likely auction mode,carbon pricing,and bidding revenue management.carbon pricing by auction is the most powerful policy tool for addressing carbon emissions reduction and implementing the Glasgow Climate Pact.

The compilation of technology lists addressing climate change has a guiding effect on promoting technological research and development,demonstration,and popularization.It is also crucial for China to strengthen ecological civilization construction,achieve the carbon emission peak and carbon neutrality target,and enhance global climate governance capabilities.This study first proposes the existing classification outline of the technology promotion lists,technology demand lists,and future technology lists.Then,different methodologies are integrated on the basis of the existing outline of four technology lists:China’s existing technological promotion list for addressing climate change,China’s demand list for climate change mitigation technology,China’s key technology list for addressing climate change,and China’s future technology list for addressing climate change.What’s more,core technologies are analyzed in the aspects of technology maturity,carbon reduction cost,carbon reduction potential,economic benefits,social influence,uncertainty,etc.The results show that:key industries and sectors in China already have relatively mature mitigation/adaptation technologies to support the achievement of climate change targets.The multi-sectoral system of promoting climate friendly technologies has been established,which has played an active role in tackling climate change.Currently,climate technology needs are concentrated in the traditional technology and equipment upgrading,renewable energy technology,and management decision-making support technology.The key technologies are concentrated in 3 major areas and 12 technological directions that urgently need a breakthrough.For carbon emmission peak and nentrality,carbon depth reduction and zero carbon emissions and geoengineering technology(CDR and SRM)have played an important role in forming the structure of global emissions and achieving carbon neutrality in the future.Thus,the uncertainty assessment for the comprehensive technology cost effectiveness,technology integration d
由经济生产过程中生产工艺的提高所带来的过程技术进步可以降低中间投入的需求,从而减少对能源的需求,降低碳排放。因此,提高过程技术水平是各国减少碳排放量的重要途径。作者以2012年的Jin模型为基础,构建了一个基于一般均衡的多国多部门经济模型,并将其与RICE模型的气候系统相结合,建立了一个经济系统与气候系统相互作用的气候-经济集成评估模型。在此模型基础上,对不同过程技术进步速率下各国、各部门碳排放与能源使用进行了模拟,模拟结果显示:过程技术进步速率的提高可以使各国各部门的能源使用高峰和碳排放高峰提前。在三种情景下,中国分别在2034年、2030年和2022年达到碳排放高峰,而在较激进的情景3下,中国从2007到2050年的累计碳排放可以减小到930亿吨碳(Gigatonnes of carbon,GtC),可以满足100GtC的排放目标。此外,随着过程技术进步速率的提高,中国和印度的减排潜力最大;在各行业中,能源业的减排潜力最大,服务业次之。
