Carbon emissions trading (abbreviated as carbon trading) is a market mechanism adopted to promote global greenhouse gas emission reduction and reduce global carbon dioxide emissions. After arduous negotiations, the United Nations Intergovernmental Panel on Climate Change (IPCC) adopted the United Nations Framework Convention on Climate Change (UNFCCC, abbreviated as "the Convention") on May 9, 1992. In December 1997, the first additional protocol to the Convention, the Kyoto Protocol (abbreviated as the Protocol), was passed in Kyoto, Japan. The Protocol established market mechanisms as a new pathway to address greenhouse gas reductions, represented by carbon dioxide, by treating carbon dioxide emission rights as a commodity. This led to the formation of carbon dioxide emission rights trading, known as carbon trading.
The CnOpenData Carbon Trading Database System in Various Regions of China integrates the complete market transaction details officially released by eight core carbon emissions trading pilots in China (Shenzhen, Beijing, Sichuan, Guangdong, Tianjin, Chongqing, Shanghai, and Hubei). This database covers up to 13 years of transaction history (Shenzhen’s data dates back to August 2013) and includes over 20,000 high-value transaction records (as of June 2026). With data granularity refined to the daily transaction level, core fields include transaction date, variety, type (listed/bulk agreement), transaction price, volume, and amount. This provides full-cycle, multi-dimensional foundational support for researching the evolution of China's carbon market, regional coordination mechanisms, and corporate carbon asset strategies.
Data Uniqueness
- Comprehensive Coverage of Core Regions: Simultaneously covers eight pilots, including Beijing, Shanghai, Guangzhou, Shenzhen + Chengdu-Chongqing, Tianjin, and Hubei (including core western markets Sichuan/Chongqing), fully presenting the complete picture of regional carbon market development in China.
- Full-Cycle Continuous Coverage: Markets such as Shenzhen (2013.8.15–2026.7.1) and Beijing (2013.11.28–2026.6.26) cover the entire cycle from the pilot launch to the present.
Data Application Value
- Academic Research: Research on regional carbon price transmission mechanisms (e.g., comparing early Shenzhen data with recent Hubei data), policy intervention effectiveness evaluation (e.g., analyzing the impact of quota auctions in Tianjin data), market liquidity measurement (constructing indicators based on 3,212 high-frequency transactions in Chongqing).
- Business Decision-Making: Corporate compliance cost calculation (using Beijing's historical price and volume data to forecast procurement costs), portfolio optimization (identifying cross-regional arbitrage opportunities through Guangdong data), carbon financial product design (developing derivative pricing models based on Shanghai data).
- Policy Evaluation: Evaluating pilot experiences (Shenzhen data supports the design of national carbon market rules), verifying regional coordination pathways (comparative analysis of data from Sichuan and Chongqing).
With its core advantages of full-cycle coverage and non-missing data across all eight pilots, this database has become an indispensable core data resource for in-depth research on China's carbon market. Whether users need to analyze pioneering practices in Shenzhen, track the historical trajectory of Shanghai, or compare the characteristics of later development in the Chengdu-Chongqing region, this database provides a robust, reliable, and high-value data cornerstone.
