ESG: From “Voluntary Commitment” to an “Investment Governance Framework”

The Role of the BOI, Foreign Investors, and Directors’ Liability in the Modern Legal Era

What is ESG?

In recent years, the concept of Environmental, Social, and Governance (ESG) has evolved significantly. It has shifted from being merely an ethical framework for corporate conduct or a voluntary corporate social responsibility (CSR) initiative aimed at enhancing corporate image, into a structural governance mechanism that materially influences investment decisions, access to capital, and legal risk assessment.

Although ESG is not traditionally classified as binding law, in practice it increasingly functions as a form of soft law, exerting systemic pressure on the business sector. This is particularly evident in the context of cross-border investment and state investment promotion frameworks.

ESG provides a framework for evaluating business operations across three principal dimensions:

Environmental – including energy consumption, greenhouse gas emissions, waste management, and impacts on natural resources.

Social – including labour rights, workplace safety, equality and non-discrimination, and personal data protection.

Governance – including board structure, transparency, internal control systems, anti-corruption measures, and executive accountability.

The essence of ESG does not lie in prohibiting business activities. Rather, it establishes expectations that organizations should exercise their economic power and discretion responsibly toward a broad range of stakeholders.

This concept reflects a broader development in modern legal systems, which increasingly move away from reliance on criminal sanctions and instead adopt preventive and structural regulatory mechanisms.

ESG and the BOI Investment Promotion System: When Incentives Come with Behavioral Frameworks

In the Thai context, the role of ESG becomes particularly evident when considered alongside the investment promotion regime administered by the Board of Investment (BOI).

Although Thailand’s investment promotion legislation does not explicitly refer to the term “ESG”, the conditions and policy directions of the BOI reflect ESG principles in a systematic manner.

The BOI does not merely function as a mechanism to grant investment incentives. Rather, it serves as a governmental instrument to shape the direction and quality of investment in Thailand.

This includes:

promoting environmentally friendly industries
imposing environmental and safety standards on industrial operations
protecting labour rights
expecting businesses to maintain transparent and accountable governance structures

Collectively, these conditions reflect ESG principles in substance, if not in explicit terminology.

In practice, receiving BOI promotion means entering a form of special regulatory regime. Investors receive not only rights but also ongoing obligations to comply with BOI conditions throughout the life of the project.

If significant violations occur, particularly regarding environmental or labour matters, the legal consequences may extend beyond fines or corrective orders. They may include suspension or revocation of investment privileges, which from a business perspective represents a far more serious structural risk than isolated regulatory penalties.

ESG from the Perspective of Foreign Investors: Risks That Should Not Be Overlooked

For foreign investors, ESG in the BOI context is not merely about responding to expectations from international capital markets or shareholders abroad. Rather, it effectively becomes a de facto condition for conducting business in Thailand.

Foreign investors who simply apply ESG standards adopted by their parent companies without adapting them to Thai legal requirements and government policies may face unforeseen risks.

For instance, environmental or labour standards used in the investor’s home jurisdiction may not fully cover the specific requirements under Thai law or BOI conditions.

If violations occur, Thai authorities may view the situation not as a mere technical error, but as a systemic failure of corporate governance.

In this sense, ESG functions as a connecting point between domestic legal requirements and the expectations of international investors and business partners.

Put differently, if foreign investors treat ESG merely as a matter of corporate image or marketing, they may significantly underestimate legal risks. Conversely, recognizing ESG as an integral component of legal risk assessment allows investors to design investment structures and compliance systems more appropriately aligned with the Thai regulatory environment.

ESG and the Liability of Directors in BOI-Promoted Companies: A Higher Standard in the Modern Era

Beyond its investment implications, ESG also directly affects the role and responsibilities of company directors, particularly in companies receiving BOI promotion.

Under corporate law principles, directors must exercise their duties with due care and in good faith for the best interests of the company.

In the ESG era, however, this duty extends beyond merely generating profits. It increasingly includes ensuring that the company systematically complies with applicable laws and regulatory conditions.

If a BOI-promoted company violates promotion conditions or related laws in a manner indicating systemic governance failure, the legal inquiry may not stop at the corporate level. Instead, attention may shift to whether directors have implemented adequate policies, internal control systems, and risk monitoring mechanisms.

ESG therefore raises the standard for evaluating directors’ liability. The focus moves beyond simply avoiding illegal conduct, toward demonstrating active oversight and effective risk governance.

In practice, directors may no longer easily argue that such matters fall solely within the responsibility of operational management if appropriate governance systems are lacking.

Thus, ESG transforms the role of directors from strategic decision-makers into risk governors, responsible for ensuring that business growth is not disrupted by legal and regulatory risks.

Unresolved Legal Questions in the Context of ESG and BOI

Despite the growing influence of ESG in investment governance, several legal questions remain unresolved within the Thai legal system.

First, in the context of BOI promotion, does ESG remain merely a policy framework and promotional condition, or is it gradually evolving into an implied legal obligation for business operators?

If ESG considerations are used by the BOI as grounds to suspend or revoke investment privileges, questions arise regarding the scope of administrative discretion and how such discretion may be reviewed under administrative law principles such as proportionality and legality.

Second, for foreign investors, it remains unclear whether ESG-based regulatory actions could affect the principle of legitimate expectations, particularly where ESG requirements are interpreted or enforced more strictly after investment promotion has already been granted.

Finally, at the level of company directors, there is still no clear boundary regarding when neglecting ESG considerations may constitute a breach of directors’ duty of care under corporate law.

These questions illustrate that ESG currently occupies a transitional space between policy-based governance concepts and fully developed legal norms.

Hypothetical Scenario: ESG in Practice within a BOI-Promoted Company

To illustrate the practical implications, consider the following hypothetical scenario.

Company A is a joint venture involving foreign investors and has received BOI investment promotion in the manufacturing sector. The company appoints a subcontractor to handle waste management from its production process.

Subsequently, the subcontractor violates environmental laws, prompting government inspection. The BOI then determines that Company A has failed to comply with the conditions of its investment promotion.

In this situation, ESG becomes highly relevant. The legal question does not stop at who directly committed the violation.

Rather, the inquiry extends to whether the company maintained adequate governance systems and supply chain oversight.

If the company lacks policies, monitoring mechanisms, or environmental risk assessments for subcontractors, the issue may be regarded as a systemic governance failure.

Such a failure may affect the company’s BOI privileges and may indirectly reflect deficiencies in the oversight responsibilities of the company’s directors.

ESG and Related Legal Frameworks: Structural Integration

ESG does not operate in isolation. Instead, it interacts with several legal frameworks.

In the Social dimension, ESG directly connects with labour law, including labour rights, workplace safety, and non-discrimination, which are key criteria used by regulators in evaluating corporate conduct.

In the Environmental dimension, ESG intersects with environmental law and factory regulations, where violations may lead to administrative sanctions affecting investment privileges.

In the Governance dimension, ESG relates to corporate law and administrative law. Weak internal control systems or insufficient oversight may be considered when assessing directors’ liability.

At the same time, the exercise of discretion by the BOI must comply with administrative law principles, including proportionality, equality, and legality.

Through this integration, ESG becomes a cross-cutting intersection of multiple branches of law, rather than merely an ethical business concept.

Future Trends and Policy Considerations

Looking ahead, ESG is likely to become more formally integrated into investment governance mechanisms.

This may occur through secondary regulations, administrative guidelines, or the use of ESG criteria in determining the granting or retention of BOI privileges.

Such developments reflect a shift in the role of the state from punitive enforcement toward behavioral governance, using economic incentives as a regulatory tool.

From a policy perspective, the key challenge lies in balancing investment promotion with the protection of public interests.

If ESG criteria are applied without clear standards or predictable expectations, they may undermine foreign investor confidence.

Conversely, if ESG frameworks are designed to be transparent, reviewable, and consistent with administrative law principles, they may serve as an important instrument for enhancing the quality and sustainability of investment in Thailand.

ESG Challenges in the Context of Thai Law

Although ESG has been widely promoted within Thailand’s business sector, its legal implementation still faces significant challenges.

One major limitation arises from its current status as soft law or policy guidance rather than binding legislation. Consequently, the scope of obligations, liabilities, and compliance standards remains unclear.

The implementation of ESG therefore relies heavily on administrative discretion and regulatory mechanisms, which may create risks of inconsistency and legal uncertainty.

Moreover, ESG compliance often focuses on policy documentation rather than genuine structural reform, resulting in “paper compliance” or ESG practices primarily aimed at improving corporate image.

Conclusion: ESG as a Condition for Sustainable Growth

In conclusion, ESG in the context of BOI investment promotion is not merely a supplementary or reputational consideration. Rather, it forms part of the structural governance framework of investment regulation in Thailand.

Foreign investors and company directors who view ESG merely as a voluntary initiative may significantly underestimate the associated legal risks.

By contrast, those who understand ESG as a legal condition for sustainable growth will be better positioned to design investment strategies, governance structures, and compliance systems aligned with both regulatory expectations and market developments in the long term.
