Carbon emissions trading (碳交易) is a market mechanism designed to promote global greenhouse gas emission reduction and mitigate 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) on May 9, 1992. In December 1997, the first supplementary agreement to the Convention, the Kyoto Protocol (《京都议定书》), was adopted in Kyoto, Japan. The Protocol introduced market mechanisms as a novel approach to address greenhouse gas emission reductions, particularly targeting carbon dioxide. By treating carbon dioxide emission rights as a tradable commodity, it established carbon emissions trading systems.

  Since October 2011, China has successively established seven major carbon emissions exchanges: the Guangzhou Carbon Emissions Exchange, Shenzhen Emissions Exchange, Beijing Environment Exchange, Shanghai Environment and Energy Exchange, Hubei Carbon Emissions Exchange, Tianjin Emissions Exchange, and Chongqing Carbon Emissions Exchange. In addition to data from these exchanges, this dataset also incorporates information from the Sichuan United Environment Exchange Carbon Trading Platform.

  On July 16, 2021, China's national carbon emissions trading market officially commenced operations, marking the establishment of the world's largest carbon market by covered greenhouse gas emissions. By July 23, the national carbon market recorded a trading volume of 112,000 tons of carbon emission allowances via挂牌协议交易, with a turnover of 6.3803 million CNY. The opening price stood at 56.52 CNY/ton, reaching a high of 61.07 CNY/ton and a low of 55.52 CNY/ton, while closing at 55.52 CNY/ton. As of July 23, cumulative trading volume in the national carbon market had reached approximately 4.83 million tons, with a total turnover of around 250 million CNY. During this period, prices fluctuated between 48 CNY/ton and 61.07 CNY/ton.

  At the critical juncture of transitioning from regional pilots to a nationwide carbon market, CnOpenData presents comprehensive carbon trading data covering eight domestic carbon emissions exchanges, providing robust support for carbon neutrality research.
