The International Organization for Standardization (ISO) is a global organization that sets standards to ensure quality, safety, efficiency, and sustainability across various industries. In recent years, ISO has developed a set of standards related to environmental, social, and governance (ESG) performance assessment, which have become essential tools for companies seeking to demonstrate their commitment to sustainability and responsible management.
What are ESG criteria? They are a set of environmental, social, and governance factors used to assess a company’s sustainability and its impact on the environment in which it operates. Each letter represents a fundamental pillar:
- E (Environmental): waste management, energy efficiency, emissions reduction, and climate change mitigation.
- S (Social): respect for human rights, equality, diversity, workplace safety, and community relations.
- G (Governance): ethics, transparency, management structure, anti-corruption policies, and risk management.
In 2025 and 2026, ESG criteria will be an essential requirement not only for attracting investors but also for maintaining sustainable business relationships. Suppliers that meet these standards will have a clear competitive advantage in bidding and supplier qualification processes, especially in industrial and corporate sectors.
Most Relevant ISO Standards for ESG Management
The following are the main ISO standards related to ESG criteria and their practical application in companies:
| ISO Standard | Description and Purpose | Application to ESG Criteria |

In addition, ISO has announced the development of new standards that will take effect between 2025 and 2026:
- ISO 37005 (scheduled for 2025): focused on ethical governance and anti-corruption efforts within organizations, complementing ISO 37001.
- ISO 59004 (scheduled for 2026): focused on the circular economy and resource efficiency, helping companies measure their circular performance and product sustainability.
Common Structure of ISO Standards (High-Level Structure – HLS)
Since 2012, ISO standards have shared a high-level structure (HLS), which allows for their integration and consistency across different management systems. This structure consists of 10 main sections:
- Organizational Context
- Leadership
- Planning
- Support
- Operation
- Performance Evaluation
- Continuous Improvement
- Risk and Opportunity Management
- Communication and Stakeholders
- Documentation and Evidence
This structure facilitates the integration of multiple management systems—such as quality (ISO 9001), environment (ISO 14001), and social responsibility (ISO 26000)—within a single organization, optimizing resources and increasing efficiency.
Benefits of Implementing ISO Standards Related to ESG
