The Rise of ESG Due Diligence Legislation and Impacts on Supply Chains

While certain specific issues such as food safety, restricted chemicals, and health and safety have been legislated for decades, responsible business conduct and due diligence have been largely managed through weak standards, voluntary initiatives, and individual companies’ codes of conduct.

This is now changing. There are a plethora of regulations and standards, schemes, certifications, and other initiatives that focus on ensuring ethical practices throughout value chains. Collectively, this legislation is known as due diligence legislation. This evolving landscape is a significant paradigm shift that highlights the growing imperative for ethical supply chain practices around the globe.

Key Takeaways

What Is Due Diligence Legislation?

Due diligence is the process that organizations should carry out to identify, prevent, mitigate, and account for how they address actual and potential adverse ethical, labor, human rights, and environmental impacts in their own operations, their supply chain, and other relationships.

While commonly labeled as mandatory human rights due diligence laws, legislation focused on ensuring due diligence typically encompasses environmental protection as well, and may have specific requirements on issues such as forced labor or conflict minerals.

In 2022, the UN General Assembly adopted a resolution stating that access to a healthy, safe, and sustainable environment is a basic human right. Thus, environmental concerns are increasingly included under the umbrella of due diligence, and environmental due diligence is included in legislation.

Global Rise in Due Diligence Legislation

In recent times, there has been a notable surge in the enactment of due diligence legislation, with a specific emphasis on Environment, Social, and Governance (ESG) considerations. This heightened focus reflects a growing recognition of the pivotal role that ethical and sustainable practices play in contemporary business operations. Ethical business conduct is no longer voluntary, but mandatory.

Human Rights

Human rights stand as a cornerstone in the spectrum of issues addressed by global due diligence legislation. Nearly ubiquitous in its coverage, this broad category is at the forefront of regulatory frameworks, reflecting the shared acknowledgment of the importance of safeguarding human rights within business operations.


Closely trailing human rights, environmental concerns form a pivotal focus of global due diligence legislation. This reflects an increasing awareness of the interconnectedness between business activities and environmental impact, highlighting the imperative for responsible practices that contribute to sustainability and the preservation of ecosystems.

Conflict Minerals

Since 2010, targeted legislation addressing metals and minerals originating from conflict-affected areas has been in effect, particularly in the United States (US) and the European Union (EU). These regulations are designed to prevent the sale of tin, tungsten, tantalum, and gold sourced from regions marred by conflicts. The focus on these minerals underscores a commitment to curbing the economic support provided to conflict zones through the trade of these materials.

Child Labor and Modern Slavery

Within the realm of labor practices, forced and child labor represent critical issues addressed by existing due diligence legislation. The inclusion of stringent measures underscores a collective commitment to eradicating exploitative labor practices and ensuring ethical standards throughout supply chains.

Several countries, such as the US (California), the UK, and Australia, have implemented due diligence legislation to eradicate slavery and human trafficking from supply chains.

In addition, import bans on products made with forced labor through tariffs or customs acts are in place in the US, Canada, and Mexico.

Timber Legality

Beyond human rights and labor, due diligence legislation extends its reach to encompass broader environmental challenges. Illegal logging, recognized as a significant threat to global ecosystems, is subject to regulatory scrutiny, aligning with legislation to curb deforestation.

Additionally, the evolving landscape acknowledges the urgency of addressing climate change, prompting legislation that encourages responsible business practices to mitigate environmental impact.

Legislation aimed at fighting illegal logging and the import of illegally harvested products exists in the EU, the US, the UK, and Australia. Due diligence includes traceability information, risk assessment, and risk mitigation.

Disclosure Requirements

A common thread in global due diligence legislation is the emphasis on transparency. Mandating disclosure and reporting requirements, these regulations aim to foster accountability, enabling stakeholders to assess the ethical and sustainable dimensions of business operations.

In the European Union (EU), numerous regulations and directives, notably the Corporate Sustainability Reporting Directive, the Taxonomy Regulation, and the Sustainable Financial Disclosure Regulation, specifically center on disclosure requirements.

Concurrently, various countries are passing legislation to detect and mitigate instances of "greenwashing," often integrated into consumer protection laws. Mitigating the risk of greenwashing allegations necessitates rigorous due diligence, traceability measures, and transparent disclosure practices by companies.
