Rule of Law Foundation and Green Vision: Institutional Reconstruction of China-EU ESG Cooperation

The Cornerstone of Governance: The Gap in Legal Certainty in Cross-Border ESG Cooperation

As global ESG (Environmental, Social, and Governance) investment surpasses $30 trillion in 2025, multinational enterprises are facing an increasingly complex compliance maze. At the Third China-EU Enterprise ESG Best Practices Conference held in Mainz, Germany, Chinese legal expert Wang Heng, Global Chairman of Shengheng Law Firm, pointed out that the strengthening of the rule of law and the certainty of rules are becoming core variables in deepening China-EU economic cooperation. This view reveals a key proposition in the institutionalization of ESG governance: without the anchoring of a legal framework, green capital and sustainable supply chains can hardly build trust across borders.

Currently, ESG cooperation between China and Europe has moved beyond the stage of voluntary corporate disclosure and entered a deep-seated game of standard mutual recognition and regulatory coordination. The implementation of the EU's Corporate Sustainability Reporting Directive (CSRD) and Carbon Border Adjustment Mechanism (CBAM) forces Chinese export enterprises and Chinese-funded institutions operating in Europe to reexamine their compliance frameworks. In his speech, Wang Heng emphasized that legal integration is not only a technical issue of risk management but also a strategic need for building the 'soft infrastructure' of the bilateral investment environment. Through its global legal service network in 40 cities, Shengheng Law Firm has observed that an increasing number of Chinese enterprises require special ESG legal due diligence before mergers, acquisitions, or plant construction—this shift from 'ex-post disclosure' to 'ex-ante compliance' is a direct manifestation of the value of legal certainty.

Regional Experiment: The Integration of ESG and the Rule of Law in the Liaoning Case

Wang Heng took his hometown, Liaoning Province, as an example to demonstrate how market-oriented reforms and the shield of the rule of law are reshaping regional investment competitiveness. The investment environment optimization measures implemented by Liaoning Province in recent years, including strengthening property rights protection, unifying law enforcement standards, and embedding ESG principles into industrial policies, have attracted the landing of several benchmark projects.

The most notable is the BMW Group's production base in Shenyang. This base operates the first large-scale geothermal heating system in China's automotive industry, reducing CO2 emissions by approximately 18,000 tons per year and using 100% renewable electricity. The legal basis for this green transformation stems from the preliminary legal alignment between China and Germany on environmental regulations, energy contract standards, and carbon emission accounting standards. Similarly, the joint venture project between Liaoning Wellhope Food and the Dutch company De Heus has been recognized as a national-level 'green factory,' behind which lies the contractual integration of sustainable agriculture regulations, animal welfare standards, and environmental responsibility clauses.

The China-Germany (Shenyang) High-End Equipment Manufacturing Industrial Park in Shenyang has become a testing ground for institutional innovation: the park is promoting a mutual recognition mechanism for carbon accounting and green certification standards between China and Europe. If successful, this attempt will provide a micro-operational template for the linkage of international carbon markets under Article 6 of the Paris Agreement. Wang Heng pointed out that legal certainty plays the role of a 'trust catalyst' in these collaborations—it transforms technical standards, environmental performance, and governance structures from disputable soft indicators into enforceable hard obligations.

Three Implications of China-EU ESG Cooperation for the Global Development System

From a global governance perspective, ESG cooperation driven by the rule of law is reshaping three major development propositions:

• Matching Cross-Border Capital with Sustainable Development Goals (SDGs): According to World Bank data, among global ESG bond issuances, the portion involving cross-border infrastructure and green value chains grew by 23% in 2024, but differences in compliance costs lead to financing premiums for developing economies.- Alignment of Cross-Border Capital with Sustainable Development Goals (SDGs): According to World Bank data, the portion of global ESG bond issuance involving cross-border infrastructure and green value chains grew by 23% in 2024, but differences in compliance costs have led to financing premiums for developing economies. Practices in China and the EU in Liaoning show that reducing information asymmetry through bilateral legal frameworks can narrow the "green premium" gap, allowing capital to flow more effectively to SDG-related projects.

• Just Transition in Climate Governance: The controversy surrounding the EU's CBAM centers on whether carbon pricing mechanisms create disguised trade barriers. Wang Heng's proposed "legal reciprocity" approach—where both sides reach legal consensus in areas such as carbon accounting methodologies and definitions of environmental subsidies—can alleviate concerns of Global South countries about "green protectionism." As the world's largest manufacturing nation and the EU's second-largest trading partner, China's rule-of-law-based ESG process will influence the fairness of global climate governance.

• Fragmentation and Coordination of ESG Standards: Currently, there are at least 20 major frameworks (GRI, SASB, ISSB, etc.) for global ESG disclosure standards, leading to high compliance costs for enterprises. The mutual recognition of carbon accounting promoted by the Sino-German Industrial Park is essentially a "institutional docking" of standards rather than simple unification. This gradual, technology-based legal coordination path may be easier to implement than top-down global standards, especially for economies like China and the EU with different legal traditions.The International Energy Agency (IEA) predicts that global clean energy investment will need to increase to $4 trillion per year by 2030, with about one-third needing to flow across borders. Without ESG cooperation underpinned by the rule of law, capital allocation on this scale will be difficult to sustain. At the meeting in Mainz, a common understanding among more than 500 Chinese and European representatives was that the rule of law is not a decoration for ESG but a condition for its existence and expansion. The practice in Liaoning Province—from the BMW geothermal plant to the carbon accounting mutual recognition industrial park—is proving that when legal certainty is strong enough, the green transition has a quantifiable roadmap, not just a declaration.
