Shanghai has completed the first paid open-market auction under its Carbon Emissions Allowance Administrative Service Trust, known as the Carbon Trust, marking a milestone in the city's carbon market reforms and advancing the market-based allocation and financialization of carbon assets.
The transaction, organized by the Shanghai Environment and Energy Exchange, was the first paid competitive bidding exercise conducted under the Carbon Trust mechanism.
Officials said the successful completion of the auction represents a significant step in strengthening market-based supply and demand regulation while creating an innovative framework that combines market regulation, carbon asset management and risk control.
The mechanism is also intended to provide a model for the financial development of China's carbon market.
The inaugural auction was conducted through the Shanghai carbon emissions spot trading system under principles of openness, fairness and impartiality. It marked the first practical application of the Carbon Trust's market-based operating mechanism.
To ensure orderly market operations and protect the interests of regulated companies, the auction established a reserve price based on market data.
The minimum bid was set at 1.06 times the weighted average transaction price of all listed carbon allowance trades completed between Dec. 1, 2025, and May 30, 2026.
Officials said the pricing approach safeguarded the value of carbon assets held by regulated enterprises while sending a stable and rational price signal to the market.
It was also designed to prevent excessive volatility in carbon prices and demonstrate the effectiveness of market-oriented price formation.
With the completion of the auction, Shanghai's carbon market has formally established a dual-track regulatory framework that combines market-based and administrative measures.
Under the new structure, the Carbon Trust serves as a flexible market mechanism to adjust liquidity by releasing tradable carbon allowances according to changing market supply and demand.
At the same time, a separate government reserve allowance mechanism, which will be introduced later, will provide non-tradable allowances as a safeguard to ensure companies can meet their compliance obligations.
Officials said the two mechanisms complement one another by creating a clearer and more structured regulatory system while improving the stability and precision of carbon market management.
The Carbon Trust is China's first specialized trust mechanism dedicated to the market-oriented and financial management of carbon emission allowances. It was officially launched in Hongkou District on Feb. 28, 2026, as one of Shanghai's key reforms in the carbon market.
Designed with reference to the European Union's Market Stability Reserve mechanism, the Carbon Trust uses a professional trust structure to centralize carbon allowance management and facilitate compliant and orderly market releases.
On May 29, 2026, the Huabao Trust–Shanghai Carbon 2030 Shanghai Carbon Emissions Allowance Administrative Service Trust was formally established, marking the transition of the Carbon Trust from institutional design to full-scale operation.
The mechanism has established a complete operational model under which companies voluntarily entrust surplus carbon allowances to the trust, which centrally manages the assets, releases allowances to the market in an orderly manner and distributes returns according to participants' respective shares.
Officials said the model transforms scattered and idle surplus carbon allowances held by enterprises into market-based environmental assets that can be regulated and appreciate in value. It is intended to improve both market regulation and corporate carbon asset utilization.
The Shanghai Environment and Energy Exchange said the first paid auction has generated multiple benefits for the carbon market, participating companies, green industries and green finance.
For the carbon market, the trust provides a market-based tool to balance supply and demand, stabilize carbon prices and strengthen the carbon pricing mechanism. Leveraging the financial characteristics of the trust structure, it also helps transform carbon allowances from compliance instruments into standardized green financial assets that can be traded and appreciate in value.
For enterprises, the mechanism activates surplus carbon allowances that might otherwise remain unused. Through centralized professional management and market operations, companies can generate more stable returns on their carbon assets while reducing the overall costs of emissions reduction. Flexible releases of allowances can also improve market liquidity and provide greater certainty for business operations and low-carbon transition planning.
At the industrial and regional level, officials said the Carbon Trust helps connect green finance with the carbon market, encouraging greater participation by green capital and supporting industrial restructuring and low-carbon development. It is also expected to provide market support for achieving China's emissions and energy control targets during the 15th Five-Year Plan period.
The Shanghai Environment and Energy Exchange said it will continue refining the Carbon Trust by expanding participation, developing additional trust products, improving the timing of allowance releases and optimizing pricing rules.
The exchange also plans to strengthen links between Shanghai's carbon market and its financial markets by leveraging the city's position as an international financial center and promoting a more diversified and multi-tiered carbon market.
The launch and operation of the Carbon Trust in Hongkou is part of the district's efforts to build a leading demonstration area for carbon finance innovation by capitalizing on its concentration of green financial institutions.
In recent years, Hongkou has made green and low-carbon development a strategic priority, supported by the North Bund's role as a hub for green industries. The district is now home to more than 1,000 green and low-carbon enterprises with a combined industry scale approaching 80 billion yuan.
As Shanghai's designated district for coordinated green and low-carbon development, Hongkou has made the sector a top government priority. Officials said the district will continue building a comprehensive green industrial ecosystem and support Shanghai's goal of becoming an internationally influential center for green services.
