China’s three major stock exchanges — the Shanghai Stock Exchange (SSE), the Shenzhen Stock Exchange (SZSE), and the Beijing Stock Exchange (BSE) — released mandatory corporate sustainability disclosure guidelines in February 2024, marking a defining shift in how ESG obligations are structured across the world’s second-largest economy. As of 2026, the guidelines are in active implementation for large listed companies, aligning China’s disclosure architecture with global frameworks including the ISSB standards, the EU’s Corporate Sustainability Reporting Directive (CSRD), and the supply chain due diligence requirements of CSDDD and Germany’s LkSG. For multinational enterprises with Chinese suppliers or Chinese-listed counterparts, these guidelines are a critical development in the convergence of global supply chain sustainability regulation.
What are the Guidelines?
On February 8, 2024, China’s three major stock exchanges in Shanghai, Shenzhen, and Beijing made a coordinated move by releasing preliminary guidelines requiring listed companies to disclose their sustainability practices. This landmark step demonstrates China’s commitment to building a sustainable, transparent economy and aligning with the global surge in environmental, social, and governance (ESG) reporting standards. By 2026, the guidelines have entered their operational phase, with mandatory reporting obligations already applying to the largest index-constituent companies and phased adoption expanding across the listed company universe.
Who Needs to Follow the Guidelines and What Do They Need to Report?
Under the finalized guidelines, constituent companies of the SSE 180, STAR 50, SZSE 100, and ChiNext indices — as well as companies listed on both domestic and international exchanges — are subject to mandatory sustainability reporting. Other listed companies are encouraged to report voluntarily, with the regulatory expectation that voluntary adoption will expand significantly through 2026 and 2027. Small and medium-sized enterprises listed on the Beijing Stock Exchange are also encouraged to voluntarily disclose, consistent with an approach that promotes progressive adoption rather than immediate universal mandates.
The guidelines require publicly listed companies to assess and disclose sustainability-related information using a comprehensive four-pillar framework: governance, strategy, risk management, and metrics and targets. This structure closely mirrors the TCFD (Task Force on Climate-related Financial Disclosures) framework adopted internationally, and the ISSB’s IFRS S1 and S2 standards — enabling multinational enterprises to align Chinese supplier disclosures with their own CSRD and CSDDD reporting requirements.
How Do the Guidelines Address Environmental and Social Issues?
The guidelines incorporate significant advances in environmental and social disclosure requirements. Listed companies must disclose their carbon emissions — including total greenhouse gas emissions and emission reduction measures — as well as their climate adaptation strategies, climate transition plans, and opportunities associated with carbon neutrality. Biodiversity and the circular economy are also explicitly addressed, reinforcing China’s alignment with the Convention on Biological Diversity and the Kunming-Montreal Global Biodiversity Framework agreed in 2022.
On the social dimension, the guidelines require companies to disclose their contributions to China’s national development strategies, including rural revitalization and innovation-driven development. Supply chain social compliance — including labour standards, human rights protections, and supplier conduct — is a key disclosure area, directly relevant to multinational enterprises assessing their Chinese supplier base under LkSG, CSDDD, or the UK and Australian Modern Slavery Acts.
The guidelines formally adopt the double materiality principle — requiring companies to consider not only how sustainability issues affect their own financial performance, but also how their activities impact the environment and society. This aligns with the double materiality concept that underpins the EU’s CSRD and ESRS standards, and represents a market-first adoption of this principle in the Chinese regulatory context. The convergence between Chinese and European approaches to double materiality makes cross-border supply chain sustainability reporting substantially more coherent for global enterprises.
When and How Will the Guidelines Be Implemented and Reviewed?
The guidelines were finalized following a public comment period that closed in late February 2024. Mandatory reporting for the largest index-constituent companies — SSE 180, STAR 50, SZSE 100, and ChiNext — began with fiscal year 2025 reporting cycles, published in 2026. The guidelines are subject to periodic review and refinement, and China’s securities regulators have signalled a phased expansion of mandatory obligations to a broader set of listed companies. English-language versions of key guidance documents have been progressively made available to support adoption by internationally listed companies and their foreign counterparts.
What are the Implications and Benefits of the Guidelines for China and the World?
The release and ongoing implementation of the guidelines has been broadly welcomed by the ESG investment community as a major step toward improving supply chain sustainability transparency in one of the world’s most consequential manufacturing and sourcing economies. China accounts for a substantial share of global manufactured goods exports, meaning that mandatory sustainability disclosures from Chinese listed companies will directly affect the supply chain due diligence datasets available to global enterprises fulfilling CSDDD, CSRD, and LkSG obligations.
The guidelines represent a significant milestone for China’s exchanges, which have been steadily expanding ESG infrastructure over the past decade. The SSE launched its ESG index in 2019 and the SZSE followed in 2020. The BSE, established in 2021, embedded ESG and innovation as core pillars from its launch. The 2024 guidelines consolidate these efforts into a unified, cross-exchange mandatory framework — a development that positions China as a significant actor in the global convergence of corporate sustainability disclosure standards.
For supply chain compliance officers and ESG managers at multinational enterprises, the practical implication is clear: Chinese listed suppliers and counterparties will increasingly be required to disclose the ESG and supply chain data that due diligence frameworks such as CSDDD and LkSG require. Aligning internal supplier assessment processes with the four-pillar disclosure structure of the Chinese guidelines will improve data quality, reduce audit burden, and strengthen the overall defensibility of enterprise human rights and environmental due diligence programmes under EU and German law.
China’s commitment to achieving the United Nations Sustainable Development Goals and the Paris Agreement is reflected throughout the guidelines — creating a strategic rationale for global companies to use these disclosures as a foundation for deeper supplier engagement, risk scoring, and corrective action management across their Chinese supply chain tiers.
Frequently Asked Questions (FAQs)
Are Chinese suppliers now required to disclose ESG data?
As of 2026, companies listed on the SSE 180, STAR 50, SZSE 100, and ChiNext indices are subject to mandatory sustainability reporting under the exchanges’ guidelines. Other listed companies are encouraged to report voluntarily. For multinational enterprises conducting supply chain due diligence under CSDDD or LkSG, these disclosures provide an increasingly robust dataset for assessing Chinese supplier ESG performance.
How do China’s sustainability guidelines relate to CSRD and CSDDD?
China’s guidelines adopt the double materiality principle and a governance-strategy-risk-metrics framework that closely aligns with CSRD’s ESRS standards and CSDDD’s due diligence requirements. While the specific reporting standards differ, the underlying disclosure architecture is compatible — enabling enterprises to use Chinese supplier disclosures as evidence in their own EU regulatory filings.
What is the double materiality principle?
Double materiality requires companies to disclose both how sustainability issues affect their financial performance (financial materiality) and how their activities impact the environment and society (impact materiality). Adopted by China’s stock exchanges and mandated under the EU’s CSRD, double materiality is rapidly becoming the global standard for enterprise sustainability reporting.
How can Certainty Software help with cross-border supply chain ESG compliance?
