Disclosure & Assurance

Build the reporting infrastructure that satisfies regulators, survives assurance, and informs the board.

  • CSRD, ESRS, and converging global frameworks demand auditable data, governance-grade controls, and evidence that withstands external scrutiny. We help corporates and financial institutions design and operationalise the reporting architecture required — from double materiality assessment through to assurance-ready evidence packs.

Who This Is For

CFOs, Sustainability Directors, Heads of Reporting, Internal Audit, and Assurance teams navigating CSRD transposition, ESRS data point requirements, and voluntary framework alignment.

What We Deliver

CSRD Implementation

End-to-end implementation of CSRD reporting obligations: gap analysis against transposed national requirements, reporting boundary definition, governance structure design, data collection architecture, and preparation for limited assurance. We work with your existing systems to build a reporting process that scales with evolving regulatory expectations.

ESRS Data Architecture

The European Sustainability Reporting Standards require hundreds of quantitative and qualitative data points. We design the data collection, validation, and aggregation architecture required to produce ESRS-compliant disclosures — including datapoint mapping, ownership assignment, internal controls, and audit trail documentation.

Double Materiality Assessment

ESRS mandates a double materiality assessment covering both impact materiality and financial materiality. We facilitate structured stakeholder engagement, sector benchmarking (using SD-KPI intelligence across 68 industries), and threshold calibration to produce a defensible materiality matrix that guides your disclosure scope.

Assurance Readiness & Evidence Packs

Limited assurance under CSRD is mandatory; reasonable assurance is expected to follow. We build the evidence infrastructure — control descriptions, process documentation, data lineage records, and testing protocols — that your external assurance provider will require. The goal is audit-ready documentation before the auditor arrives.

Voluntary Frameworks

GRI, CDP, TCFD, and ISSB alignment. For organisations reporting under multiple frameworks, we design integrated reporting architectures that satisfy overlapping requirements without duplicating effort. Where ESRS and ISSB converge, we build once and report twice.

Regulatory Context

This practice is driven by:

    • CSRD (Directive (EU) 2022/2464) — Core EU corporate sustainability reporting obligation. Phased rollout from FY 2024; post-Omnibus scope narrowed to 1,000+ employees and EUR 450M turnover. → CSRD Guide

    • ESRS (Delegated Regulation (EU) 2023/2772) — The 12 European Sustainability Reporting Standards: 2 cross-cutting, 5 environmental, 4 social, 1 governance. ~320 mandatory datapoints post-Omnibus simplification. → ESRS Guide

    • EU Taxonomy Regulation — Article 8 Reporting (Regulation (EU) 2020/852) — Mandatory disclosure of Taxonomy-eligible and Taxonomy-aligned revenue, CapEx, and OpEx KPIs within the management report. Article forthcoming.

    • ESRS Voluntary Standards for SMEs (LSME / VSME) — Simplified reporting frameworks for SMEs in the value chain of CSRD-reporting entities; determines how data requests cascade through supply chains.

    • Omnibus Simplification Package (COM(2025) 80/81) — Revised CSRD scope thresholds, simplified materiality requirements, and reduced datapoint burden.

    • CSDDD (Directive (EU) 2024/1760) — Due diligence obligations that intersect ESRS disclosure requirements across human rights (S1-S4) and environmental (E1-E5) topical standards. → CSDDD Guide

    • EU Audit Regulation and Directive (as amended for sustainability assurance) — Legal framework for sustainability assurance engagements; defines who can provide assurance and under what standards.

    • ESEF / ESRS Digital Taxonomy (iXBRL) — Mandatory machine-readable digital tagging of ESRS datapoints in management reports, enabling automated regulatory data extraction.

    • NFRD (Directive 2014/95/EU) — Predecessor non-financial reporting framework; still applicable to certain entities during CSRD transition period.

    • Accounting Directive (Directive 2013/34/EU, as amended) — Legal basis for the management report where sustainability disclosures are embedded.

    • EFRAG Implementation Guidance (IG 1: Materiality Assessment; IG 2: Value Chain; IG 3: Datapoint List) — Detailed technical guidance on applying ESRS standards in practice.

    • EFRAG ESRS Q&A Platform — Rolling clarifications from the standard-setter on interpretation questions.

    • CEAOB Sustainability Assurance Standards — European audit oversight body guidance on the transition from limited to reasonable assurance for sustainability statements.

    • IAASB ISSA 5000 — International Standard on Sustainability Assurance; the global baseline assurance standard expected to become authoritative for EU sustainability audits.

    • National CSRD Transposition Measures — Member State implementation specifics including France, Germany, and the Netherlands; local enforcement approaches and additional requirements.

    • AMF / BaFin / AFM National Enforcement Guidance — National regulator approaches to CSRD compliance monitoring and enforcement priorities.

    • ISSB / IFRS S1 & S2 — Global sustainability disclosure baseline; relevant for dual-reporting companies subject to both ESRS and ISSB jurisdictions. → ISSB Guide

    • GRI Universal Standards 2021 — ESRS incorporates and cross-references GRI reporting principles; relevant for companies with existing GRI reporting infrastructure.

    • TCFD Recommendations — Climate disclosure framework now embedded in ESRS E1 (Climate Change) and ISSB S2.

    • TNFD Recommendations (v1.0) — Nature and biodiversity disclosure framework complementing ESRS E4 (Biodiversity and Ecosystems). Article forthcoming.

    • ISO 14001 / ISO 26000 — Environmental management and social responsibility frameworks providing evidence base for ESRS disclosures.

    • AA1000 Assurance Standard — Alternative assurance framework for sustainability information.

    • CDP Questionnaires — Environmental disclosure platform serving as a readiness pathway for CSRD reporting.

    • SBTi — Science Based Targets initiative; referenced in ESRS E1 as a credibility benchmark for emission reduction targets.

    • SASB Standards (now IFRS Foundation) — Sector-specific materiality mapping useful for identifying industry-relevant ESRS topics.

    • UN Global Compact — Communication on Progress — Annual reporting framework with significant content overlap with ESRS requirements.

    • EU EMAS (Eco-Management and Audit Scheme) — Voluntary environmental management and reporting scheme recognised under EU law.

Enhanced by Data & Intelligence

SD-KPI Standards provide sector-specific materiality benchmarks across 68 industries — an empirical foundation for double materiality assessments that goes beyond peer comparison to identify the ESG indicators genuinely correlated with financial performance in your sector.
