ESG reporting, or sustainability reporting, has become a fundamental process for companies to transparently communicate their environmental, social, and governance performance. It is no longer an optional or purely superficial activity, but a strategic element that responds to the growing expectations of investors, customers, regulators, and talent.
Drafting an effective sustainability report requires a thorough understanding of reference standards, the metrics to be monitored, and industry best practices. This process not only enhances corporate reputation but also helps identify risks and opportunities, optimize resource use, and build a more resilient business model. With the introduction of regulations like the Corporate Sustainability Reporting Directive (CSRD) in Europe, the quality and reliability of ESG reporting have become imperative.
This comprehensive guide provides a clear overview of how to structure effective ESG reporting, analyzing international standards, essential metrics, and best practices to adopt.
What Are ESG Reporting Standards?
ESG reporting standards are frameworks and guidelines that define what information a company should collect, measure, and communicate regarding its sustainability activities. They provide a common structure that allows for the comparison of performance across different companies and sectors, ensuring consistency, completeness, and reliability of data. Adopting recognized standards is the first step toward credible reporting.
The most widely used frameworks globally include:
- Global Reporting Initiative (GRI): The GRI Standards are among the most widespread in the world for sustainability reporting. They are modular and apply to any type of organization. Their approach is based on identifying the significant impacts the company has on the economy, environment, and people, in line with the principle of impact materiality.
- Sustainability Accounting Standards Board (SASB): The SASB standards focus on financial materiality. They identify the ESG topics most likely to influence the financial performance and value of a company in a specific industrial sector. They are particularly valued by investors for their focus on financially relevant data.
- European Sustainability Reporting Standards (ESRS): Developed by EFRAG and outlining the requirements of the CSRD, the ESRS are mandatory for European companies subject to the directive. These standards integrate the concept of double materiality, requiring companies to report on both their impacts on society and the environment (impact materiality) and how sustainability factors affect the company (financial materiality).

Key ESG Metrics: What to Measure?
Once the reference standard has been chosen, the next step is to define the metrics (or KPIs, Key Performance Indicators) to concretely measure performance. Although the exact metrics depend on the material topics identified for your company and sector, it is possible to identify some common categories. [Consult the map of ESG topics by sector]
Environmental Metrics
These metrics quantify the company's impact on the environment.
- Greenhouse gas emissions: Total CO2 equivalent emissions (Scope 1, 2, and 3).
- Energy consumption: Total amount of energy consumed and the percentage from renewable sources.
- Waste management: Total amount of waste produced and the percentage of waste recycled or reused.
- Water consumption: Total water withdrawal and the percentage of water recycled.
Social Metrics
These metrics concern the company's relationships with its internal and external stakeholders.
- Diversity and inclusion: Percentage of women in leadership roles, gender pay gap.
- Occupational health and safety: Injury frequency rate (e.g., LTIFR - Lost Time Injury Frequency Rate).
- Training and development: Average hours of training per employee.
- Supply chain management: Percentage of suppliers assessed on social and environmental criteria.
Governance Metrics
These metrics evaluate the quality of corporate management and oversight.
- Board of Directors composition: Percentage of independent directors, gender diversity on the board.
- Ethics and anti-corruption: Number of confirmed incidents of corruption and actions taken.
- Executive compensation: Ratio of CEO total compensation to the median employee compensation.
Best Practices for Successful ESG Reporting
Going beyond simple compliance is what distinguishes a good sustainability report from an excellent one. Adopting certain best practices can transform the sustainability report into a powerful communication and strategy tool.
- Integrate Sustainability into Corporate Strategy: ESG reporting should not be an isolated activity of the sustainability department. The best companies integrate ESG performance into business objectives, also linking it to executive compensation.
- Base Reporting on a Double Materiality Analysis: Identify the topics that truly matter, both for the company's impact on the world and for its financial results. This approach, required by the CSRD, ensures that the report focuses on the most relevant information.
- Ensure Data Quality and Verification: ESG data must be as reliable as financial data. Implementing robust data collection processes and subjecting the report to third-party verification (assurance) increases credibility and stakeholder trust.
- Tell a Story with Data: Numbers alone are not enough. A good report contextualizes data, explains trends, clarifies objectives, and describes the actions taken. Storytelling helps to make the information more understandable and engaging.
- Use Technology to Simplify the Process: ESG reporting can be complex and time-consuming. Adopting specialized software allows for the automation of data collection, management of workflows, real-time monitoring of KPIs, and generation of reports compliant with various standards.
(Conclusion: Reporting as a Strategic Compass)
ESG reporting is a journey, not a destination. It is a process of continuous improvement that, when executed well, offers invaluable worth. The adoption of recognized standards, the measurement of relevant metrics, and the application of best practices transform the sustainability report from a mere regulatory obligation into a strategic compass. It allows companies to navigate the challenges of the ecological and social transition, strengthening stakeholder trust and creating lasting value for the business, society, and the planet.
