Mitigating ESG Risks in Third-Party Relationships: The Crucial Role of Internal Audit

In the contemporary business landscape, Environmental, Social, and Governance (ESG) factors are pivotal in evaluating a company’s commitment to sustainable operations. This blog post delves into the role of internal audit in managing ESG risks, particularly in the context of third-party risk management.

Understanding Third-Party Risk

Third-party risk arises when businesses engage external entities – such as software providers, suppliers, or consultants – to augment their capabilities or improve efficiency. These collaborations, while beneficial, introduce additional risks, including ESG risks, that must be meticulously managed.

Decoding ESG Risk

ESG risk assessment isn’t straightforward. For internal auditors, understanding the organization’s ESG risk profile is crucial before evaluating how third-party collaborations impact these risks. This requires a thorough understanding of the vendor’s third-party risk management policies and the organization’s contracting processes to ensure comprehensive coverage of ESG risks.

Key Stages in Managing Third-Party Relationships

1. Due Diligence and Evaluation

This initial phase involves building a business case and gathering information to identify potential partners and assess risks. It should be a well-defined and documented process.

2. Onboarding and Operationalizing

Post due diligence, the chosen vendor is onboarded. This stage includes setting up the operational aspects of the relationship and ensuring the third party’s integration into the business processes.

3. Monitoring

Continuous monitoring is essential. This includes evaluating vendor performance against established metrics and staying abreast of any changes in the vendor agreement. Key aspects of monitoring include:

  • Governance: Includes IT risks and data governance. With the increasing adoption of cloud services, ensuring data privacy, security, and reliability is crucial.
  • Legal Contract Compliance: Ensuring written contracts and compliance with their terms is vital. This includes monitoring legal and contractual obligations and leveraging “right to audit” clauses where appropriate.
  • Business Operations Satisfaction: Regular assessment of the third-party relationship is necessary to ensure it meets the established risk requirements. This often involves extensive record-keeping and documentation.

The Role of Internal Audit in ESG Third-Party Risk Management

While internal audit teams may not directly make vendor management decisions, they play a crucial role in ensuring due diligence during vendor selection. Once vendor relationships are established, these teams are responsible for monitoring these partnerships to mitigate new risks and ensure the effectiveness of controls.


In conclusion, managing ESG risks in third-party relationships is a complex but essential aspect of modern business operations. Internal audit teams are at the forefront of this challenge, ensuring that while organizations leverage external expertise and services, they remain committed to their ESG goals and maintain a sustainable, responsible business model.
