The ESRS E4 Standard: Biodiversity and Ecosystems

The main drivers of change in biodiversity and ecosystems are climate change, pollution, land and sea use change, direct exploitation and natural ecosystems. The ESRS standards establish disclosure requirements regarding the company's relationship with terrestrial, freshwater and marine habitats, ecosystems and populations of related fauna and flora species, including diversity within and between species. Specifically, the objectives of the ESRS E4 standard are to push companies to understand and communicate the impacts on biodiversity and ecosystems.

The ESRS (European Sustainability Reporting Standards) constitute a set of European standards and indicators for sustainability reporting. Founded on a dual materiality approach, these standards aim to standardise companies' non-financial information, addressing environmental, social and governance (ESG) issues. The first category focuses on the company's environmental impact and is divided into several criteria: E1 Climate Change; E2 Pollution; E3 Water and Marine Resources;E4 Biodiversity and Ecosystems; E5 Resource Use and Circular Economy.

The ESRS E4 standards aim to encourage companies to understand and communicate how their activities affect biodiversity and ecosystems, considering both positive and negative material impacts, actual and potential. Companies must also report the results of their actions to prevent or mitigate significant negative impacts, to protect and restore biodiversity. Furthermore, it is crucial that they describe their ESG reporting strategy that contains the ability to adapt their strategies and business models to planetary constraints, as well as the main risks and opportunities associated with these impacts. Finally, they must consider the short-, medium- and long-term financial impacts arising from these risks and opportunities, making sure to comply with the ESRS Directive E4 - CSRD.

Companies are required to submit a transition plan that aligns their business model with the preservation of planetary boundaries and the integrity of the biosphere, in accordance with the objectives of the EU Biodiversity Strategy 2030. This plan must be approved by administrative and supervisory bodies. In addition, they must detail the resilience of their biodiversity strategy, including an analysis of risks and opportunities. They must outline processes for identifying and assessing significant impacts on biodiversity and ecosystems and provide methods for recognising these effects in all their operations.

Measuring biodiversity is a more complex task than quantifying CO2 emissions, as the latter represent a single measurable element. In contrast, biodiversity encompasses a wide range of interconnected components, including species diversity, ecosystem health and genetic diversity. Despite these difficulties, recent developments have led to the creation of key performance indicators (KPIs) that allow companies to assess their impact on nature. This is achieved by integrating different data sources, such as satellite images to monitor deforestation and academic databases, and transforming them into viable and manageable indicators.

Through the use of biodiversity metrics, companies can identify areas where their negative impact is most significant and implement strategies to reduce it. This proactive approach not only enables compliance with regulations, but also contributes to improving the company's reputation and operational efficiency. By adopting sustainable practices and optimising the use of natural resources, companies can also increase their market competitiveness. Key indicators for biodiversity are: ecosystem integrity; biodiversity decline; land degradation; water stress.

The indicators are crucial for companies to make informed decisions to reduce their environmental impact. Specifically, indicators have the following role:
- measure the health and functionality of ecosystems. Companies can use satellite images to monitor deforestation rates and habitat fragmentation;
- monitoring populations and species diversity in a specific area provides insights into the health of the local environment;
- assessing soil health and changes in land use helps companies understand the long-term sustainability of their practices (for more information, read our article on monitoring deforestation);
- monitoring water use and availability is essential to prevent over-exploitation in water-scarce areas.

The ESRS requires the disclosure of significant ESG information following the principle of double materiality. The materiality assessment, as stipulated by ESRS 1, must identify the significant information to be disclosed, considering both impact and financial materiality. This assessment is the starting point for sustainable reporting according to ESRS. In ESRS 1, impact materiality and financial materiality are defined as follows. An ESG topic is considered 'material' if it meets the criteria for impact materiality, financial materiality, or both. The assessments of these two dimensions of materiality are linked and must be considered together. Companies should describe how they apply the materiality criteria for both dimensions, using appropriate thresholds to assess impacts, risks and opportunities, and how these have been managed.

An issue of sustainability is relevant from an impact perspective when it concerns actual or potential, positive or negative material effects of the company on people or the environment in the short, medium or long term. Relevant ESG topics include those related to the company's operations and value chain, including interactions through products, services and business relationships. These relationships concern not only direct contracts, but also those along the value chain, both upstream and downstream.

An ESG topic is considered financially relevant if it can generate or is expected to generate significant effects on the company. This can occur when a sustainability topic involves risks or opportunities that affect, or could affect, performance, financial position, cash flows, access to finance or the cost of capital in the short, medium or long term. The assessment of financial materiality involves identifying information that is considered important to the primary users of financial statements in making decisions about the resources available to the company. Information is considered material if its omission or misrepresentation could influence decisions based on the sustainability budget.

The assessment of materiality is fundamental to sustainability reporting according to the ESRS. To support this analysis, a list of sustainability topics covered by the ESRS 1 thematic standards is provided. The starting point for the materiality assessment generally includes areas where impacts, risks and opportunities are likely to occur, based on the company's activities, business relationships, geographies and other risk factors. In this context, the XNatura Platform by 3Bee Ecosystem, supports companies and municipalities in monitoring their impacts and dependencies on nature, with the aim of developing customised climate strategies. The platform assigns a risk score that identifies sites in need of priority action, facilitating strategic planning in line with the CSRD directive and international standards such as ESRS E4 and GRI 101.
