Summary of Key Points
The 2025 A-share Environmental Risk List shows that as of June 2026, more than 160 listed companies still have not eliminated their environmental penalty records from 2025. The coal industry accounts for over 40% of the companies on the list (with the highest risk proportion), followed by the basic chemicals sector; approximately 60% of the top 10 riskiest companies have changed significantly, with China Communications Construction rising from 100th place last year to first. One-quarter of the listed companies have not disclosed their ESG reports (although they are not required to do so). There are issues with environmental information queries, such as expired links and cumbersome procedures. The upcoming Environmental Ecology Code will significantly increase the cost of non-compliance for businesses, turning green transformation from a voluntary initiative into a legal requirement.
I. More than 160 Companies with Penalties on the List: The Coal Industry as a "Hard Hit Area," Four Industries with Zero Risk
The 160 companies were selected from the 629 enterprises that exposed environmental risks in 2025; their penalty records have not been removed from the "Credit China" database as of June 2026.
- Significant Industry Differences: The coal industry stands out, with 15 companies on the list (40.54% of the total), all being coal mining enterprises. The basic chemicals sector has the highest number of listed companies (18), including Xinhecheng, which has a market value of nearly 100 billion yuan and was fined over 80,000 yuan for its subsidiaries' violation of volatile organic compound emissions regulations.
- Industries with Zero Risk: The textile and clothing, defense and military, beauty and care, and communications sectors have achieved zero environmental risk records this year, indicating that these industries are doing well in terms of green compliance.
- Case Study: Yankuang Energy: Although it is a popular stock with doubled market value this year, several of its subsidiaries have received environmental fines (mainly for safety-related violations), but their overall risk level is not high, and they have received ESG awards. This shows that having penalties does not necessarily mean poor green performance; the nature of the violations and the extent of rectification are important factors to consider.
II. Major Changes in the Top 10 Risk Companies: Sixty Percent of Companies Have Replaced
Six of the top 10 riskiest companies this year are new additions, highlighting the dynamic nature of environmental risks. Companies can quickly move from low-risk to high-risk if they do not pay attention to compliance.
- China Communications Construction's Rise: Last year it was ranked 100th; this year it has jumped to first place due to a subsidiary, China Communications Fourth Harbor Engineering Co., Ltd., which had three unresolved penalties totaling over 20 million yuan. The most serious violation involved unauthorized earthwork and stone extraction outside a highway construction zone without a mining license, resulting in a fine of 3.46 million yuan and a 1.38 million yuan penalty.
- Common Issues in the Construction Industry: China Communications Construction's issue is not isolated; environmental violations during construction (such as illegal earthwork and pollution) are common in the construction and decoration sectors. The delayed disclosure of penalties also contributes to the concentrated exposure of risks.
III. ESG Reports: One-Quarter of Listed Companies Have Not Submitted
ESG reports serve as a company's "green report card" (covering environmental, social, and governance aspects). This year, some companies are required to disclose them:
- Mandatory Scope: Companies in the SSE 180, STAR 50, and SZSE 100 indices must submit their 2025 ESG reports by April 30, 2026.
- Status of Listed Companies: Among the more than 160 listed companies, one-quarter have not submitted ESG reports, although they are not within the mandatory disclosure category (with an average market value of less than 9 billion yuan).
- Investor Perspective: ESG reports are important for investment decisions, but since voluntary disclosure is still in its early stages, many smaller companies have not given them much attention.
IV. High Barriers to Environmental Information Access
Listed companies are required to provide links to environmental information in their annual reports, but there are numerous practical issues:
- Problems with Links: Some links display "under development," some only show the system name without providing access, and some PDF files cannot be opened.
- Distributed Subsidiaries: Companies often have subsidiaries that disclose information on different systems, making it difficult for investors to obtain a comprehensive view of all subsidiary violations with a single search.
V. Implementation of the Environmental Ecology Code in August: Doubled Cost of Non-Compliance, Green Transformation Becomes Mandatory
On August 15, 2026, China's second "code" (the Environmental Ecology Code) will take effect, replacing ten old environmental protection laws, with significant implications for businesses:
- Increased Costs of Non-Compliance: For example, falsifying monitoring data can result in fines for both the company and its responsible individuals (up to 50,000 yuan and a 10-year ban from the industry).
- Green Transformation as a Legal Requirement: Green transformation is no longer optional; it has become a legal obligation. Failing to comply could lead to legal consequences.
- Long-Term Impact: The new code will encourage companies to prioritize environmental compliance, as non-compliance may result in heavier penalties and even career bans for executives, thus accelerating the process of green transformation.
In summary, the exposure of environmental risks among A-share listed companies is influenced by industry-specific factors (such as high violations in the coal and chemicals sectors) and management shortcomings (inadequate compliance by subsidiaries). The upcoming Environmental Ecology Code will make non-compliance more costly for businesses, making green transformation a necessity. For investors, evaluating companies will require attention to not only their financial performance but also their environmental compliance, as the cost of non-compliance is increasing and the associated risks are growing.
