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 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, namely the Kyoto Protocol (abbreviated as the Protocol), was adopted in Kyoto, Japan. The Protocol introduced market mechanisms as a novel approach to address greenhouse gas emission reductions represented by carbon dioxide—treating carbon dioxide emission rights as a commodity, thereby establishing carbon emission rights trading, abbreviated as carbon trading.
The CnOpenData Carbon Trading Database System for Chinese Regions integrates complete market transaction details officially released by China's eight key carbon emissions trading pilot regions (Shenzhen, Beijing, Sichuan, Guangdong, Tianjin, Chongqing, Shanghai, Hubei). This database covers over 12 years of trading history (Shenzhen data dates back to August 2013) and contains 21,739 high-value transaction records (as of June 2025). Data granularity extends to daily transaction levels, with core fields including transaction date, trading variety, transaction type (spot trading/block trading), transaction price, transaction volume, and transaction amount, providing full-cycle, multi-dimensional foundational support for researching China's carbon market evolution, regional coordination mechanisms, and corporate carbon asset strategies.
Data Uniqueness
- Comprehensive Coverage of Core Regions: Simultaneously covers Beijing, Shanghai, Guangzhou, Shenzhen + Chengdu-Chongqing, Tianjin, and Hubei—all eight pilot regions (including key western markets Sichuan/Chongqing)—fully presenting the developmental landscape of China's regional carbon markets.
- Full-Cycle Continuous Coverage: Markets such as Shenzhen (2013.8.15-2025.6.4) and Beijing (2013.11.28-2025.6.23) encompass complete cycles from pilot launch to present.
Data Application Value
- Academic Research: Regional carbon price transmission mechanisms (e.g., comparing Shenzhen’s early data with Hubei’s recent data), policy intervention effect evaluation (e.g., analyzing the impact of allowance auctions in Tianjin’s 1,043 records), market liquidity measurement (constructing indicators based on Chongqing’s 3,212 high-frequency transactions).
- Business Decision-Making: Corporate compliance cost estimation (using Beijing’s 2,043 historical price-volume records to forecast procurement costs), portfolio optimization (identifying cross-regional arbitrage opportunities through Guangdong’s 2,532 records), carbon financial product design (developing derivative pricing models based on Shanghai’s 3,134 records).
- Policy Evaluation: Assessing pilot experiences (Shenzhen’s 11,760 records supporting national carbon market rule design), validating regional coordination pathways (comparative analysis of Sichuan’s 1,249 and Chongqing’s 3,212 records).
With its core strengths of a 12-year full-cycle span and comprehensive coverage of all eight pilot regions, this database serves as an indispensable resource for in-depth research on China's carbon market. Whether users need to analyze Shenzhen’s pioneering practices, track Shanghai’s historical trajectory, or compare the late-mover characteristics of the Chengdu-Chongqing region, this database provides a solid, reliable, and high-value data foundation.
