Abstract 

With the increasing severity of global climate change, countries worldwide are proposing carbon 

emission reduction targets to promote green and low-carbon development. As one of the world's 

largest carbon emitters, China has also put forward the “Dual Carbon” goals, namely carbon peak 

and carbon neutrality. Carbon emissions trading, as an important emission reduction tool, is gaining 

attention from governments. To achieve the “Dual Carbon” goals, constructing a unified carbon 

market is essential. The Chengdu-Chongqing economic circle, a significant economic hub in Southwest 

China, possesses unique geographical and resource advantages. The integrated development of its 

carbon emissions trading is of great importance for advancing the national carbon market. This paper 

focuses on the legalization path for constructing a unified carbon market in Chengdu-Chongqing under 

the “Dual Carbon” goals, aiming to promote sustainable development in the Chengdu-Chongqing 

economic circle, achieve the “Dual Carbon” goals, and provide a legalization path reference for 

integrated carbon emissions trading in other regions of China.

1. Introduction 

The escalating global climate crisis necessitates urgent transitions to low-carbon economies worldwide. 

As the world’s largest carbon emitter, China’s commitment to its “Dual Carbon” goals—achieving 

carbon peak and carbon neutrality—is of paramount importance. In this context, carbon emissions

trading systems (ETS) have emerged as a crucial market-based instrument to cost-effectively reduce 

emissions. While China’s national ETS is operational, the development of regional unified markets 

offers a strategic pathway to optimize carbon resource allocation and deepen market mechanisms. The 

Chengdu-Chongqing Economic Circle, a pivotal growth pole in Western China, possesses a robust 

economic foundation, synergistic policies, and shared emission reduction imperatives, making it an 

ideal candidate for such an initiative. However, the successful construction and stable functioning of a 

cross-regional carbon market hinge on a sound legal framework. This paper, therefore, focuses on 

exploring the legalization path for building a unified carbon market in Chengdu-Chongqing, aiming to 

provide a replicable model for regional carbon market integration underpinned by the rule of law. 

 

2. The Development Trajectory of China’s Carbon Emissions Trading Market 

2.1 Initiation: The Stage of Experience Accumulation and Capacity Building in China’s Participation in 

International Carbon Emission Trading under the CDM Mechanism 

In May 2004, China’s National Development and Reform Commission issued the “Interim Measures 

for the Operation and Management of Clean Development Mechanism Projects,” strengthening the 

management of CDM project activities based on the Kyoto Protocol, thus initiating China’s 

cooperation with developed countries in international carbon trading (Song, C. Y., 2011). Influenced by 

restrictions on EU CDM projects, China suspended international CDM projects from 2013. 

2.2 Pilot Stage: The Stage of Local Pilot Carbon Trading Markets 

Although China suspended international CDM projects, it drew on the EU ETS to launch pilot carbon 

emissions trading markets (ETS) in China, and 借鉴 the CDM mechanism from the Kyoto Protocol to 

introduce China’s Chinese Certified Emission Reduction (CCER) mechanism, beginning efforts to 

establish a domestic carbon emissions trading market. This created a dual-track system with pilot ETS 

and the CCER mechanism operating simultaneously. However, due to unsatisfactory operational 

performance after its launch, including low voluntary emission reduction trading volumes, irregularities 

in some projects, and supply-demand imbalances, the CCER project registration was suspended in 

March 2017, though existing CCERs could still be traded. 

In September 2010, the State Council issued the “Decision on Accelerating the Cultivation and 

Development of Strategic Emerging Industries,” explicitly calling for the establishment and 

improvement of trading systems for major pollutants and carbon emissions, marking China’s initial 

exploration of a carbon emissions trading market. Subsequently, on March 16, 2011, the “Outline of 

the Twelfth Five-Year Plan for National Economic and Social Development of the People’s Republic 

of China” was published, proposing the gradual establishment of a carbon market and the promotion of 

low-carbon pilot demonstrations. In October of the same year, the National Development and Reform 

Commission issued the “Notice on Launching Pilot Carbon Emissions Trading,” approving pilot 

programs in Beijing, Tianjin, Shanghai, Chongqing, Guangdong, Hubei, and Shenzhen (Liu, Y., 2018). 

By 2018, Fujian became the eighth pilot carbon trading market, signifying substantial progress in

building China’s carbon emissions trading market. These pilot markets extensively covered over 20 

industries, including power, steel, and cement, involving nearly 3,000 key emitting entities. The 

establishment of these pilots laid a solid foundation for the construction and implementation of the 

national carbon emissions trading system and provided valuable experience for China in the carbon 

market domain. 

2.3 Rapid Development Stage: The National Unified Carbon Trading Stage After 2021 

China’s national carbon market commenced trading simultaneously in Beijing, Shanghai, and Wuhan 

on July 16, 2021, marking the official start of nationwide operations (Yuan, J. Q., 2021, pp. 63-66, p. 

80). Regarding the trading mechanism, the national carbon exchange retained the dual-track system 

used in regional pilots, dominated by quota trading and supplemented by CCERs (Yuan, J. Q., 2021, pp. 

63-66, p. 80). According to Article 29 of the “Measures for the Administration of Carbon Emissions 

Trading” issued by the Ministry of Ecology and Environment in January 2021, key emitting entities can 

use CCERs to offset their carbon emission quota compliance obligations annually, with an offset limit 

not exceeding 5% of the required quotas (Wang, S. Y., 2022). In terms of market structure, both the 

national carbon exchange and pilot carbon exchanges remain open, presenting a complementary 

relationship between the two market types. Currently, the national carbon market only covers over 

2,000 enterprises in the power sector. This single-sector coverage indicates a need for future expansion 

and refinement. Predictions suggest that, starting from the power sector, the market will gradually 

expand to include industries such as chemicals, non-ferrous metals, and domestic civil aviation, making 

the carbon control mechanism more comprehensive. 

On October 19, 2023, the “Measures for the Administration of Voluntary Greenhouse Gas Emission 

Reduction Trading (Trial)” was officially released by the Ministry of Ecology and Environment and the 

State Administration for Market Regulation. This signifies that following the announcement of the first 

batch of CCER project categories by the Ministry, entities can apply for the issuance of new CCERs, 

marking the restart of CCER trading in China. 

 

3. Overview and Development Trends of China’s Carbon Emissions Trading Market under the “Dual 

Carbon” Goals 

3.1 Market Overview 

China has currently formed a new landscape where regional carbon markets and the national carbon 

market develop concurrently (Li, Y., 2022, pp. 84-89). The national carbon emissions trading market 

adopts a unified national trading architecture, with central authorities setting policies and rules, 

establishing carbon exchanges, and enterprises trading carbon emission allowances through these 

exchanges. The national market operates on a membership system, where members can participate 

directly, while non-members can trade via public bidding platforms. Concurrently, China is actively 

promoting the development of regional carbon markets to foster carbon reduction and economic 

development at the local level. 



www.scholink.org/ojs/index.php/elp                   Economics, Law and Policy                        Vol. 8, No. 2, 2025 

238 
Published by SCHOLINK INC. 

The main trading products in China’s carbon market are carbon emission allowances and voluntary 

emission reductions. Carbon emission allowances are quotas allocated by the state to enterprises, which 

must comply within specified periods or face penalties. Voluntary emission reductions are carbon 

credits purchased voluntarily by enterprises or institutions to offset their own emissions. Furthermore, 

China is exploring the development of other carbon financial products, such as carbon funds and 

carbon bonds, to meet diverse investor needs. 

The market primarily employs a bidding model for trading. Enterprises or institutions can buy and sell 

carbon allowances through the exchanges, basing their decisions on their own needs and market 

conditions. China has also established a carbon emission allowance registry to record and manage the 

holding and transfer of allowances. Additionally, monitoring and verification mechanisms ensure 

accurate measurement and reporting of actual enterprise emissions. 

Trading is primarily conducted via spot transactions, where parties settle allowance trades within a 

specified timeframe. China is also actively exploring derivative instruments like futures and options to 

enhance market liquidity and risk management tools. Furthermore, cross-regional trading is supported 

to optimize the allocation of carbon resources and foster market integration. 

3.2 Development Trends 

3.2.1 Trends in the Allowance Trading Market 

As China’s carbon market evolves, the sectoral coverage of the allowance market will gradually 

expand. Starting with the power sector, it will progressively encompass other high-energy consumption 

and high-emission sectors, such as petrochemicals, chemicals, building materials, steel, non-ferrous 

metals, pulp and paper, and domestic civil aviation. This expansion will engage more industries and 

enterprises, driving further market development. Concurrently, with market scale growth and 

participant diversification, the trading mechanism will become more refined. Stricter market oversight 

will ensure accurate emission monitoring and reporting, while more trading modes like auctions and 

negotiations will be introduced to cater to different participants. Future applications of blockchain and 

artificial intelligence are expected to enhance transaction efficiency, transparency, and risk 

management capabilities, providing a more convenient trading platform and accurate data 

monitoring/reporting, thereby increasing market fairness and transparency, thus supporting further 

market development. 

3.2.2 Trends in the Voluntary Emission Reduction Market 

With heightened national focus on the “Dual Carbon” goals and policy impetus, the scale of China’s 

voluntary emission reduction market is poised for growth, potentially attracting more entities and 

boosting trading activity. Currently centered on carbon allowance trading, the market may expand into 

related areas like low-carbon technologies and products, presenting new opportunities and challenges. 

3.2.3 Carbon Inclusion 

Against the backdrop of national market sector expansion and gradual quota reduction, diversifying 

trading products becomes essential to meet corporate compliance and trading needs. Promoting the

restart of CCER (already implemented) and integrating carbon inclusion reductions into the carbon 

market are key directions for building a multi-layered carbon market. Compared to the CCER market, 

carbon inclusion can connect more Small, Medium, and Micro Enterprises (SMEs) and involve the 

public, offering diverse carbon reduction development scenarios. 

 

4. Foundations and Value of Constructing a Unified Carbon Market in the Chengdu-Chongqing 

Region under the “Dual Carbon” Goals 

4.1 Practical Foundations for a Unified Carbon Market 

The Chengdu-Chongqing Economic Circle is situated at the intersection of the “Belt and Road” 

Initiative and the Yangtze River Economic Belt, serving as the starting point of the New Western 

Land-Sea Corridor. It boasts unique advantages in connecting Southwest and Northwest China and 

linking East Asia with Southeast and South Asia. The region features excellent ecological endowment, 

abundant energy and mineral resources, dense urban clusters, and diverse landscapes. It is the most 

populous, industrially robust, innovative, market-rich, and open area in Western China, holding a 

unique and strategic position in the national development landscape. In 2011, the State Council 

approved and the NDRC issued the “Chengdu-Chongqing Economic Zone Regional Plan,” aiming to 

build it into a key economic center in Western China, a significant modern industrial base, a testing 

ground for deepening inland opening-up, a demonstration zone for balanced urban-rural development, 

and a safeguard zone for ecological security in the upper Yangtze River. In October 2021, the CPC 

Central Committee and State Council issued the “Outline of the Chengdu-Chongqing Economic Circle 

Construction Plan,” emphasizing that amidst profound and complex changes in domestic and 

international conditions, promoting the Circle’s development facilitates the formation of a 

complementary, high-quality regional economic layout (Liu, B., & Xie, W., 2022, pp. 74-82). 

Given the growing prominence of global climate change, the international community widely 

recognizes the importance of carbon reduction. The Chinese government prioritizes carbon reduction, 

integrating carbon peak and neutrality into its national development strategy. Against this backdrop, 

constructing a unified carbon market in the Chengdu-Chongqing Economic Circle aligns with national 

and international trends, facilitating global carbon reduction cooperation. The construction possesses 

several practical foundations: First, Economic Foundation: The region is an economic hub in Western 

China with a relatively developed economy and industrial system. Key industries targeted for 

development include electronics information, automobiles, equipment manufacturing, and consumer 

goods, each aiming for trillion-yuan scale. The region is also a major energy consumer, providing a 

solid economic basis for a unified carbon market. Second, Policy Foundation: The governments of 

Chengdu and Chongqing jointly released the aforementioned Outline, explicitly advocating for green, 

low-carbon development, strengthening joint ecological environment construction and protection, and 

building a green ecological base. Both governments have also formulated specialized plans like the 

“Ecological Environmental Protection Plan for the Chengdu-Chongqing Economic Circle,” detailing 



www.scholink.org/ojs/index.php/elp                   Economics, Law and Policy                        Vol. 8, No. 2, 2025

cooperation in the dual carbon domain. Third, Technological Foundation: Advances in technology have 

led to the development of various carbon reduction technologies. China has mastered advanced 

technologies including clean energy, energy efficiency, and carbon capture, utilization, and storage, 

providing the technical basis for the market. Fourth, Market Demand Foundation: Rising environmental 

awareness has led more enterprises and individuals to focus on carbon emissions. Concurrently, as the 

carbon market matures, demand for carbon trading is increasing, providing a broad market demand 

base. 

The Chengdu-Chongqing Economic Circle exhibits high economic scale and potential. The two cities 

possess complementary and synergistic effects in economy, technology, and culture, offering vast 

cooperation space. Regarding carbon reduction, they share the same atmospheric environment and face 

similar pressures and challenges. Beyond practical foundations, conditions for a unified market include 

complementary industrial chains, synergistic policy frameworks, and shared emission reduction 

requirements. The region has relatively complete industrial chains spanning energy, transportation, 

industry, and agriculture. Complementarity among these sectors provides favorable conditions; for 

instance, clean energy development in the energy sector can synergize with electric vehicle promotion 

in transportation for coordinated emission reduction. Policy documents like the Outline provide the 

policy basis and support. Both cities face significant emission pressures, necessitating effective 

measures. A unified carbon market can achieve emission reduction and optimal allocation through 

market mechanisms, meeting their shared requirements. In summary, conditions for building a unified 

carbon market in the Chengdu-Chongqing region are relatively mature. 

4.2 Value and Significance of a Unified Carbon Market 

A regional carbon market can use carbon trading as a vehicle to open channels for industrial integration 

and complementary advantages. Leveraging comparative advantages and similarities in living habits 

and geographical environment, it can establish a unified factor flow system, promoting the achievement 

of the “Dual Carbon” goals in the region. Establishing a unified carbon market enables optimal 

allocation and trading of carbon reduction resources, enhances carbon reduction efficiency, and fosters 

sustainable development. 

The region possesses substantial carbon resources; a unified market facilitates their efficient allocation 

and utilization, encouraging active participation from enterprises and individuals for optimal carbon 

reduction and trading outcomes. It avoids market fragmentation, ensuring fairness, justice, and 

transparency. As a major economic center with numerous enterprises and residents, a unified market 

would promote carbon trading with other regions, increase trading opportunities, and enhance both 

environmental and economic benefits. 

The region is a high energy-consuming area; promoting green, low-carbon development is crucial for 

carbon reduction. A unified carbon market provides economic incentives and support for clean energy 

development, encouraging investment and accelerating the transition. Its establishment requires 

accurate carbon accounting and monitoring, prompting greater emphasis on emission supervision and

management, strengthening awareness and action for emission reduction. Furthermore, it elevates 

environmental awareness and action among enterprises and individuals. Through participation in 

carbon trading, they become more concerned with reducing their carbon footprint and environmental 

impact, actively adopting protective measures. 

In summary, within the global context of carbon reduction, a unified carbon market in the 

Chengdu-Chongqing Economic Circle aligns with national and international trends. Through policy 

support and bilateral cooperation, it can effectively advance carbon reduction efforts, achieve emission 

targets, and promote green, low-carbon development. 

 

5. Research on the Legalization Pathway for Constructing a Unified Carbon Market in the 

Chengdu-Chongqing Region under the “Dual Carbon” Goals 

5.1 Necessity Analysis for the Legalization Pathway 

5.1.1 Ensuring Stable Operation of the Unified Carbon Market 

The establishment of a unified carbon market requires safeguarding the rights and interests of all 

participants, including enterprises, individuals, and the government. Constructing a legalization 

pathway involves enacting relevant laws and regulations to define carbon trading rules and systems, 

protect participants’ legitimate rights and interests, and ensure market fairness, justice, and 

transparency. Legal institutions provide clear rules and arrangements, offering essential support and 

guarantee for the carbon trading market’s operation, ensuring compliance with legal provisions, 

preventing misconduct and fraud, and maintaining market order and stability. 

5.1.2 Promoting Green and Low-Carbon Development 

A legalization pathway provides legal basis and protection for green, low-carbon development. By 

formulating relevant laws and regulations that clarify environmental protection and carbon reduction 

targets and standards, it encourages active participation in carbon trading and facilitates the realization 

of green, low-carbon development. It also standardizes and supervises market operations. Defining 

trading rules, participant rights protection, and handling of violations enhances market transparency 

and standardization. 

5.1.3 Perfecting the Legal System for National Ecological Civilization Construction 

The unified carbon market involves cooperation and coordination across multiple administrative 

regions. Ensuring smooth operation requires perfecting the national legal system for ecological 

civilization, clarifying its goals, principles, and policy measures. Relevant legislation provides legal 

basis and guidance, promoting the organic integration of carbon market development with ecological 

civilization construction. The legalization pathway also clarifies environmental responsibilities and 

legal liabilities. Legislation defines the environmental protection duties of enterprises and individuals, 

specifies legal liabilities and penalties for violations, prompting greater emphasis on environmental 

protection and advancing both ecological civilization and carbon market construction.

242 
Published by SCHOLINK INC. 

5.2 Feasibility Analysis for the Legalization Pathway 

5.2.1 Continuous Improvement of the National Legal System Provides Legal Safeguards 

With increasing national emphasis on climate change and carbon emission control, China’s legal 

framework in environmental protection is continuously improving. Laws such as the “Environmental 

Protection Law of the People’s Republic of China” and the “Air Pollution Prevention and Control Law 

of the People’s Republic of China” provide the basic legal framework for emission reduction and 

carbon trading. For instance, the Environmental Protection Law stipulates fundamental principles and 

government responsibilities, including air pollution control and reduction requirements, forming the 

foundational legal basis. The Air Pollution Prevention and Control Law clarifies principles, targets, and 

responsibilities for air pollution prevention, requiring the establishment and improvement of a carbon 

emission trading system, providing direct legal basis. The “Measures for the Administration of 

Greenhouse Gas Emission Rights Trading” is China’s first administrative measure specifically for 

carbon emissions trading, outlining basic principles, management institutions, and trading rules. The 

“Administrative Licensing Law of the People’s Republic of China” governs administrative licensing 

procedures, including those for carbon emission trading, providing legal assurance for administrative 

management. Additional regulations and policy documents offer more specific and detailed legal 

support. China’s active participation in international carbon market cooperation, such as joining the 

Paris Agreement, provides further legal basis and an international cooperation platform. 

5.2.2 Strong Foundation in Local Legislation and Judicial Safeguards in the Chengdu-Chongqing 

Region 

The region, being economically dynamic, possesses a degree of autonomy in local legislation, enabling 

it to formulate specific regulations tailored to local carbon trading realities. This includes defining 

operating institutions, trading rules, and supervisory measures through local legislation, laying the 

groundwork. The local court systems and arbitration institutions are relatively well-developed, capable 

of resolving carbon trading disputes and protecting rights, thus possessing strong judicial safeguarding 

capabilities. Reliable judicial mechanisms are crucial for addressing contract disputes and penalizing 

violations. The local judicial system can provide efficient, fair, and professional protection, offering 

reliable support for legalization. Furthermore, the region has a sufficient number and quality of law 

firms and legal service institutions capable of providing professional legal consultation, compliance 

guidance, and dispute resolution services, effectively supporting the market’s legalized development. 

Lastly, local governments demonstrate strong commitment and action in promoting economic 

development and environmental protection. Establishing a unified carbon market aligns with local 

development strategies and policy orientations, and government support will provide policy backing 

and coordinated promotion for the legalization pathway. 

5.2.3 Availability of International and Domestic Experiences for Reference 

Successful unified carbon markets exist internationally, such as the EU ETS and the bottom-up 

regional integration experience of the United States. The EU ETS, established by Directive 2003/87/EC, 



www.scholink.org/ojs/index.php/elp                   Economics, Law and Policy                        Vol. 8, No. 2, 2025 

243 
Published by SCHOLINK INC. 

commenced in 2005. A complete legal framework forms its foundation, and standardized derivative 

trading mechanisms drive market unity. While the US lacks a national carbon market, it offers a 

transitional model where regional agreements facilitate bottom-up integration of local markets amidst 

regional disparities, gradually moving towards unification, creating conditions for a national market. 

Regional consensus on carbon emissions lays a legal foundation, and flexibility in integration is 

coordinated through varied regional policies. 

Domestically, the experience of integrated carbon reduction coordination governance in the Yangtze 

River Delta region can serve as a reference. The “Opinions on Fully, Accurately, and Comprehensively 

Implementing the New Development Concept to Achieve Carbon Peak and Carbon Neutrality” issued 

by the CPC Central Committee and State Council in September 2021 emphasized strengthening green, 

low-carbon development orientation within the Yangtze River Delta integration strategy. The Delta, 

with its economic, technological, and resource advantages, has opened the Shanghai ETS and 

implemented control measures, coordinating carbon reduction policies considering regional differences 

to achieve efficient regional emission reduction goals (Dong, W., Zhu, W. Z., & Qin, G. W., 2022, pp. 

11-18). 

In summary, the improving national legal system, the solid foundation in local legislation and judicial 

safeguards in the Chengdu-Chongqing region, and the availability of international and domestic 

experiences provide feasibility for constructing a legalization pathway for the unified carbon market. 

Establishing a unified legal framework and rules through law can ensure stable market operation and 

promote green, low-carbon development. 

5.3 Overall Framework and Specific Pathway Design 

The construction of the unified carbon market should adhere to market-oriented and legalization 

principles, with the overarching goal of promoting integrated carbon emissions trading development 

within the Circle, establishing a fair, transparent, and efficient market to achieve a win-win situation for 

climate change mitigation and economic development. 

First, the market must be governed by clear laws and regulations covering market access, trading rules, 

trading mechanisms, and regulatory responsibilities. At the national level, relevant laws and regulations 

should be formulated or refined to affirm the legal status and authority of carbon emissions trading. 

Simultaneously, the Chengdu and Chongqing governments should enact local regulations and policies 

based on local conditions to provide more specific guidance and guarantees for integration. These 

regulations should be developed by legislative bodies through a process incorporating stakeholder input 

to ensure scientificity, fairness, and operability. 

Second, enforcement must be strengthened, and unlawful activities penalized. Increased penalties for 

violations raise the cost of non-compliance, maintaining market fairness and order. A robust 

enforcement mechanism should be established, with heightened efforts to combat violations such as 

fraudulent trading, market manipulation, and misinformation. A dedicated carbon trading enforcement 

team could be established to enhance supervision and enforcement. A reporting system should also be 



www.scholink.org/ojs/index.php/elp                   Economics, Law and Policy                        Vol. 8, No. 2, 2025 

244 
Published by SCHOLINK INC. 

implemented to encourage public oversight and reporting of violations, safeguarding market fairness 

and transparency. 

Third, a judicial guarantee mechanism should be established to ensure market fairness, justice, and 

transparency. Disputes are inevitable and require timely and effective resolution. A specialized carbon 

trading dispute resolution body, staffed by arbitrators or judges with expertise in carbon trading, should 

be created. Additionally, legal aid services for the carbon market should be enhanced. Given the 

diverse participants, including potentially vulnerable SMEs or individuals with limited legal knowledge, 

legal aid institutions can provide consultation, assistance, and education, helping protect rights and 

improve legal awareness. 

Fourth, legal supervision must be strengthened. A sound legal supervision mechanism is necessary to 

prevent and combat illegal activities in carbon trading. A dedicated regulatory agency for carbon 

emissions trading should be established to oversee market operations, ensuring fairness, transparency, 

and effectiveness. The Chengdu and Chongqing governments should jointly formulate unified market 

rules and supervisory mechanisms covering access, trading rules, and procedures. Supervision 

mechanisms must be robustly built and rigorously enforced to ensure standardized operation and 

effective oversight. 

Fifth, an information disclosure system must be established, strengthening the supervision and publicity 

of carbon emissions data. Accurate and reliable data is crucial for effective market operation. A robust 

carbon emissions data supervision mechanism must be created to ensure data authenticity and accuracy. 

Concurrently, promoting the disclosure and sharing of carbon emissions data allows market 

participants and the public to monitor emissions, enhancing market transparency and credibility. 

Enterprises should be required to regularly disclose their carbon emissions information and trading 

details, increasing market transparency and preventing fraudulent activities. 

Sixth, cooperation and exchange must be enhanced. The Chengdu and Chongqing governments should 

strengthen cooperation and exchange in carbon emissions trading, jointly promoting market 

standardization and integrated development. Given the cross-regional and international nature of 

carbon markets, the legalization pathway requires enhanced international cooperation and exchange. 

Learning from existing international carbon markets, studying foreign laws and regulations, and 

continuously improving domestic systems and mechanisms through collaboration with other countries 

and regions can foster the internationalization of the Chengdu-Chongqing carbon market. 

 

6. Conclusion 

Under the “Dual Carbon” goals, constructing a unified carbon market in the Chengdu-Chongqing 

region holds significant importance for promoting green, low-carbon development. By formulating 

sound laws and regulations, establishing regulatory mechanisms, implementing information disclosure 

systems, and strengthening enforcement, a legalized pathway for the carbon market can be constructed. 

This will help ensure market fairness, transparency, and effectiveness, fostering green, low-carbon

development in the region and nationwide. Ultimately, it aims to achieve the goals of standardizing and 

integrating the carbon emissions trading market within the Chengdu-Chongqing Economic Circle, 

providing valuable reference for the construction of the national carbon market.
