Real estate & infrastructure · ESRS E4 · Biodiversity net gain
For real estate
and infrastructure.
Construction creates direct biodiversity impact. ESRS E4 and national biodiversity net gain frameworks require you to account for it.
The regulatory direction is clear. Construction and development create direct, measurable biodiversity impact — and multiple frameworks now require that impact to be documented, assessed, and countered with evidence of positive contribution.
ESRS E4 — large real estate companies
Real estate and infrastructure companies meeting CSRD thresholds must apply double materiality to biodiversity. Sensitive area proximity, habitat disruption during construction, and land-use change are all potential material impacts. Where material, DR E4-3 requires documented evidence of positive nature contributions.
UK BNG — regulatory precedent
The UK's mandatory biodiversity net gain requirement — in force from February 2024 for most planning applications — has established a legal precedent that other jurisdictions are tracking. Developers must demonstrate a measurable 10% net gain against a documented ecological baseline, creating demand for auditable positive-contribution evidence.
EU member state permit conditions
Across the EU, planning and environmental permit conditions increasingly reference biodiversity indicators — habitat connectivity, species presence, green infrastructure ratios. As CSRD embeds biodiversity disclosure into the reporting mainstream, these local permit requirements and corporate disclosure obligations are converging.
Where the disclosure gap sits
Three challenges specific to
construction and development.
Construction-phase impact documentation
ESRS E4 requires companies to assess and disclose their significant impacts on biodiversity, including those from construction and development activity. The challenge is that construction impacts are often addressed informally through planning conditions, without producing documentation structured for CSRD purposes. Auditors reviewing E4 disclosures will ask what the basis is for impact assessment — and expecting planning documents to carry that weight creates risk.
Net gain calculation and positive contribution evidence
Under biodiversity net gain frameworks — including the mandatory UK BNG regime and emerging EU member-state permit conditions — developers must demonstrate that development results in a measurable improvement in biodiversity compared to the pre-development baseline. This requires a documented positive contribution to nature, not just mitigation of harm. biodiversity.earth credits provide the documented evidence of a positive contribution that supports net gain positions.
Sensitive area proximity classification
ESRS E4 Appendix B requires companies to classify operations by proximity to sensitive areas: UNESCO World Heritage sites, IUCN category I–VI protected areas, Key Biodiversity Areas, and other designated sites. Real estate and infrastructure companies with development pipelines across multiple geographies need a structured approach to this classification, linked to their project-level monitoring data.
Credits as compensation
evidence — not construction offsets.
Biodiversity credits from biodiversity.earth are documented positive contributions to nature recovery. They are not offsets for construction damage — that distinction matters for how they appear in ESRS E4 disclosures.
Under DR E4-3, companies disclose actions taken and resources allocated to address their biodiversity impacts. Credits are disclosed alongside — not in place of — impact mitigation measures. They strengthen the positive side of a disclosure that also includes site-level habitat management, sensitive area avoidance, and construction-phase mitigation.
Disclosure note: Credits should be characterised accurately in ESRS E4 disclosures — as nature stewardship contributions, separate from impact mitigation measures at the construction site. Your external assurance provider and legal counsel should review the disclosure characterisation.
The positive contribution record
Ecological baseline, active restoration programme, continuous satellite monitoring, and five-year outcome assessment — documented evidence that a specific parcel of land is recovering under an active intervention programme.
Geographic traceability
Every credit corresponds to a GPS-bounded parcel with coordinates, land-cover data, and a monitoring record. Not a registry number — a specific place with a documented history.
Structured for external assurance
The audit documentation package is structured to support ISAE 3000 assurance of your ESRS E4 disclosures. Your assurance provider can independently verify the credit evidence against satellite data and field audit records.
TNFD LEAP geographic data
Parcel-level ecosystem condition, habitat classification, and land-cover change data supports the Locate and Assess phases of TNFD LEAP — relevant for real estate and infrastructure companies assessing sensitive area proximity.
Technical reference
ESRS E4 Appendix B and TNFD LEAP
in a construction context.
ESRS E4 Appendix B
Requires classification of sites and operations by proximity to protected areas and high-biodiversity-value land. Parcel-level GPS data from biodiversity.earth credits provides geographic reference points for the Assess phase of this classification.
TNFD LEAP — Locate and Assess
The Locate phase of TNFD LEAP requires identifying which operations are in or near sensitive areas. The Assess phase requires evaluating nature dependencies and impacts at those locations. biodiversity.earth provides the ecosystem-condition and land-cover data that feeds both phases.
UK Biodiversity Net Gain (mandatory)
From February 2024, most planning permissions in England require a measurable 10% biodiversity net gain. Credits backed by independently audited ecological baselines and satellite monitoring provide auditable positive-contribution evidence aligned with the Biodiversity Metric 4.0 framework.
ISAE 3000 assurance readiness
Real estate and infrastructure companies under CSRD will face external assurance of their sustainability disclosures. The documentation package — ecological baseline, monitoring summaries, five-year assessment, and audit evidence file — is structured for third-party ISAE 3000 assurance.
Reporting requirements vary
by portfolio and jurisdiction.
The right starting point is a structured briefing: your portfolio, your sensitive area exposure, your CSRD timeline, and how biodiversity credits fit alongside your existing site-level measures.
