1. Understanding IROs
The identification and evaluation of Impacts, Risks and Opportunities (IROs) is a central component of the double materiality assessment (DMA) within the Corporate Sustainability Reporting Directive (CSRD). Companies must assess their impact on the environment and society as well as the financial risks and opportunities posed by sustainability issues. A sound analysis of IROs is crucial to meet regulatory requirements and enable strategic sustainable corporate governance.
The European Sustainability Reporting Standards (ESRS), developed as part of the CSRD, require companies to systematically record and report on sustainability issues. IROs play a key role here. They serve as the basis for the double materiality assessment and give companies a clear structure for reporting.
Definition of IROs
Impacts: Companies have a direct or indirect impact on the environment and society through their business activities, products or services. These impacts can be both positive and negative and affect various interest groups such as employees, people in the value chain, customers or nature.
Risks: Sustainability issues harbor potential risks for companies, which can manifest themselves in financial, legal or operational disadvantages. In addition to traditional risks such as flooding, stricter environmental legislation or changes in market requirements can lead to financial burdens or reputational damage.
Opportunities: Sustainability issues also offer opportunities. Companies that implement sustainable strategies early can secure competitive advantages, promote innovation and tap into new markets. Investing in renewable energies, for example, can bring long-term cost savings and image benefits.
The role of IROs in the double materiality assessment
The double materiality assessment looks at two perspectives:
-
Inside-out perspective (impact materiality): How does the company affect the environment and society? Example: A production company causes CO2 emissions and contributes to the climate crisis. Positive and negative impacts (the I in IRO) are always assigned to impact materiality.
-
Outside-in perspective (financial materiality): How do external sustainability factors affect the company? Example: Rising CO2 prices can lead to higher operating costs and affect profitability. Risks and opportunities (the R and O in IRO) are always assigned to financial materiality.
These two perspectives are closely linked and help companies to develop a holistic sustainability strategy.
IROs vs. (sub)themes
The ESRS AR 16 topic list covers ten standards in the areas of environment, society and governance (ESG) along with the respective sub-topics and sub-sub-topics. This forms the basis for sustainability reporting. Within these sub-themes, companies must identify and assess impacts, risks and opportunities.
IRO examples
Impacts, opportunities and risks should be clear, differentiated, comprehensible and assessable. The following examples are taken from the DNK's "IROs - Impacts, Risks and Opportunities" guidelines:
| Type | ESRS topic | Description |
|---|---|---|
| Financial risk | E1 Climate change - climate protection | Working hours have to be changed or shortened due to extreme weather conditions (heat, heavy rain), jeopardizing smooth work processes. |
| Financial risk | E1 Climate change - adaptation to climate change | Political decisions tighten regulatory requirements, accompanied by rising compliance costs (transition risk). |
| Potential negative impact | E4 Biodiversity and ecosystems | Raw material extraction and land sealing can weaken or destroy ecosystems. |
| Actual positive impact | E3 Water and marine resources - water consumption | The use of service water and rainwater contributes to the conservation of water resources. |
Measures established to reduce a negative impact are not positive impacts. Do not confuse mitigation actions with positive impacts when classifying IROs.
2. Challenges with IROs and how IRO examples can help
Identifying and evaluating IROs presents companies with major challenges. The process is complex and resource-intensive. Small and medium-sized companies in particular face difficulty in identifying the relevant IROs and assessing them meaningfully.
Complexity of the process
Identifying relevant IROs requires a comprehensive analysis of the entire value chain. Companies need to consider regulatory requirements, market trends, stakeholder expectations and internal business processes. This takes considerable time and effort. The ESRS set clear requirements for the identification and reporting of these aspects, requiring thorough documentation.
Need for specialized knowledge
Precise IRO identification often requires specialized expertise. Companies need to evaluate different data sources and consider stakeholder perspectives to determine the relevance of individual sustainability issues. Without structured methods or tools, this process can be inefficient and error-prone.
Lack of standardized solutions
Each business unit has to identify different IROs, so there is no universal solution that standardizes the process unless materiality assessment software or a template is used. Companies face the challenge of developing their own valuation models, which causes additional work.
Uncertainty about the right number of IROs
What is the right number of IROs to identify and assess to meet the auditor's requirements for CSRD implementation?
There is no single answer, as the right number depends heavily on the business model, the industry and other factors. However, the first sustainability reports in the CSRD report list and materiality assessment benchmark studies can serve as a guide. For SMEs, the average number of IROs is around 200 to 300.
3. ESRS IRO database: IRO examples in practice
To make it easier for companies to identify and evaluate IROs, CSR Tools developed the ESRS IRO database. This database offers a structured collection of pre-formulated IRO examples specifically tailored to ESRS requirements.
Purpose of IRO examples in a database
The ESRS IRO database helps companies identify the relevant IROs quickly and efficiently. It serves as a tool to significantly speed up the double materiality assessment process and ensure consistent reporting.
Content and structure of the IRO database
- Pre-formulated IRO examples structured according to the specific requirements of ESRS
- Cross-industry applicability covering a wide range of sustainability topics, including industry-specific IRO examples
- Easy integration into existing processes: the IRO examples can be used directly in your materiality assessment regardless of whether you use software or an Excel tool
Time savings through IRO examples
Identifying IROs usually requires extensive research and analysis, which can take between 20 and 40 hours depending on the size and structure of the company. Added to this is the time required to formulate and justify the IROs, around 5 minutes per IRO. Using the pre-formulated IRO examples from the database significantly reduces this workload. Companies can use the examples directly in their materiality assessment or integrate them with minimal adjustments, saving up to 85% of the time required.

Frequently asked questions about IRO examples and the ESRS IRO database
What are IROs in the context of CSRD?
IROs stands for Impacts, Risks and Opportunities. They are the core elements of the double materiality assessment required under CSRD and the ESRS. Every company must identify and assess IROs across its value chain. This covers both how it affects the environment and society (inside-out) and how sustainability factors affect its finances (outside-in).
How many IROs should a company identify for its materiality assessment?
There is no fixed number. The right amount depends on the business model, industry and value chain complexity. Based on the first published CSRD sustainability reports and benchmark studies, SMEs typically identify around 200 to 300 IROs. The ESRS IRO database provides a comprehensive starting point to build your longlist efficiently.
How much time can the IRO database save?
Identifying and formulating IROs from scratch typically takes between 20 and 40 hours of research and analysis, plus around 5 minutes per individual IRO. Using pre-formulated examples from the database can reduce this effort by up to 85%, as you can copy and adapt rather than starting from a blank sheet.
Can I use the IRO examples with my existing materiality assessment template?
Yes. The IRO examples are designed to integrate directly into common formats including the materiality analysis Excel template and software tools like Materiality Master. You filter the relevant examples, copy them into your template and adjust the wording to match your specific business context.
