China is adjusting its approach to decarbonisation amid its 15th Five-Year Plan, emphasizing enhanced regulatory frameworks for corporate sustainability reporting while slowing the pace of emissions reduction targets. The government aims to reduce carbon dioxide emissions intensity—measured as emissions per unit of gross domestic product—by 17 percent by 2030, down slightly from the 18 percent reduction goal under its previous plan.

Although the overall emissions target reflects a more modest ambition, Beijing is tightening oversight on how companies disclose their environmental and sustainability practices. Starting in 2024, the stock exchanges in Beijing, Shanghai, and Shenzhen introduced guidelines making sustainability reporting mandatory for major listed firms, requiring disclosure of not only environmental metrics but also governance, strategy, risk management frameworks, and specific targets. The first batch of mandatory reports, due by April 30, reportedly achieved full compliance among 430 listed companies.

This reporting regime incorporates international sustainability standards but also includes features tailored to China’s regulatory environment. The framework parallels standards promoted by the International Sustainability Standards Board (ISSB), particularly regarding the treatment of sustainability risks and opportunities. However, Chinese guidelines place a stronger emphasis on serving broader stakeholder interests beyond investors and encourage—but do not mandate—the disclosure of Scope 3 emissions, which encompass upstream and downstream emissions linked to a company's supply chain and customers. This contrasts with frameworks such as IFRS S2, which require more comprehensive emissions reporting.

The adoption of a "four-pillar" sustainability reporting model—covering governance, strategy, risk management, and metrics—and the principle of double materiality narrow the corporate sustainability focus to include both financial risks to the business and environmental and social impacts. Companies have had to reorganize board committees and improve data collection systems to meet these standards, which remain part of a broader national architecture for sustainability disclosure.

Alongside the exchange guidelines, China’s Ministry of Finance released Basic Standards for Corporate Sustainability Disclosure in 2024. These initiatives share common reporting principles and aim to establish comprehensive sustainability reporting standards nationally by 2030, with key standards expected by 2027.

Experts note that China’s reporting regime serves purposes beyond investor transparency. Analysts highlight that the primary audience for disclosed data is the state itself, which leverages this information to enforce policy, regulate industries, and track progress toward national climate commitments. Given the government’s dual role as regulator and a controlling shareholder in many large emitters, improved disclosure helps Beijing manage systemic climate risks and enforce decarbonization objectives.

Enhanced corporate transparency may also influence financial markets. As lenders and investors gain access to standardized, reliable environmental data, sustainability disclosures are expected to play a growing role in shaping capital allocation and cost. Existing green finance policies already link financing conditions to environmental and transition performance, and clearer disclosure frameworks could further facilitate access to green funding and reinforce China’s broader climate strategy.
