ESRS E4 Biodiversity
ESRS E4 on biodiversity and ecosystems is one of the most technically demanding CSRD standards. It requires site-level impact assessments, alignment with the TNFD framework, and disclosure of land use change. Most companies are significantly underprepared.
ESRS E4 on biodiversity and ecosystems is one of the most technically demanding CSRD standards. ESRS E4 requires disclosure of: your impacts and dependencies on biodiversity and ecosystems; how these are assessed and managed; targets for biodiversity protection and restoration; and metrics on land use, ecosystem condition, and species impacts.
What ESRS E4 requires
ESRS E4 requires disclosure of: your impacts and dependencies on biodiversity and ecosystems; how these are assessed and managed; targets for biodiversity protection and restoration; and metrics on land use, ecosystem condition, and species impacts.
The most challenging requirement is site-level assessment — you must identify which of your sites are located in or near biodiversity-sensitive areas, including: Natura 2000 sites (EU protected areas), UNESCO World Heritage Sites, Key Biodiversity Areas, and areas at high risk from climate change.
For each material site, you must assess the nature-related impacts and dependencies — what does your business take from nature (dependencies) and what does it do to nature (impacts)?
TNFD alignment and E4
The TNFD (Taskforce on Nature-related Financial Disclosures) published its final recommendations in September 2023. ESRS E4 was developed in parallel and aligns closely with the TNFD LEAP approach (Locate, Evaluate, Assess, Prepare).
Companies implementing TNFD are well-positioned for ESRS E4 compliance. Key data requirements overlap: site location data, ecosystem mapping, impact driver identification, and financial exposure quantification.
The TNFD provides sector-specific guidance for 11 sectors — mining, oil and gas, electric utilities, agriculture, food and beverage, pharmaceuticals, chemicals, real estate, financial services, transportation, and retail.
Common exclusions and phase-in reliefs
E4 is one of the most commonly deferred ESRS modules in first-year reporting. Companies assess it as not material based on their sector (e.g. pure digital businesses with no physical operations in sensitive areas) or defer under transitional provisions.
Transitional provisions: ESRS E4-48 (anticipated financial effects from biodiversity risk) is subject to a 3-year phase-in for Wave 1 reporters. Several other E4 datapoints have similar reliefs.
For companies that do have material biodiversity exposure, deferral is a significant reputational and regulatory risk — NGOs and investors are specifically monitoring biodiversity disclosures.
Frequently asked questions
Do technology companies need to report ESRS E4?
Only if biodiversity is material. Most pure digital businesses have minimal direct biodiversity impacts. However, data centres (land use, water consumption), hardware manufacturers (rare earth mining), and companies with physical infrastructure may have material E4 exposure.
What is the SBTN (Science Based Targets for Nature)?
SBTN provides a framework for setting science-based targets for nature, aligned with the Global Biodiversity Framework (30x30 targets). SBTi covers climate; SBTN covers nature. Both are increasingly expected alongside ESRS E4 disclosures.
How do we identify biodiversity-sensitive areas near our sites?
Use the IBAT (Integrated Biodiversity Assessment Tool) to screen site locations against global protected area databases. The WRI Biodiversity Risk Filter and ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure) tool also provide biodiversity risk screening.
