What does a Sustainability or ESG Officer do?
The Sustainability Officer (often labelled ESG Officer, Head of Sustainability or CSRD Officer) is responsible for fulfilling the reporting obligations of the Corporate Sustainability Reporting Directive (CSRD, Directive 2022/2464/EU of 14.12.2022). Germany has not yet transposed the CSRD into the HGB: §§ 289b, 289c and 315c HGB still carry the non-financial statement of the predecessor directive. Until transposition, content and assurance follow the directive itself. The management report is extended by a dedicated sustainability statement that must follow the European Sustainability Reporting Standards (ESRS) under Articles 19a and 29a of the Accounting Directive. Delegated Regulation (EU) 2023/2772 enacted ESRS Set 1 with the twelve standards ESRS 1, ESRS 2, ESRS E1 to E5 (climate, pollution, water, biodiversity, circular economy), ESRS S1 to S4 (own workforce, value chain workers, affected communities, consumers) and ESRS G1 (governance).
Applicability rolls out in three waves. Wave 1 covers former NFRD entities (listed companies above 500 employees) from financial year 2024. Wave 2 captures all large undertakings as defined by § 267 HGB (meeting at least two of: 25 million EUR balance sheet, 50 million EUR turnover, 250 employees) from financial year 2027 after the postponement by Directive (EU) 2025/794. Wave 3 picks up listed SMEs from financial year 2028. Third-country undertakings with more than 150 million EUR EU turnover follow from 2028. Directive (EU) 2025/794 of April 2025 formally moved those dates back by two years; further Omnibus proposals stay non-binding until adopted.
The sustainability officer coordinates the double materiality assessment (impact and financial under ESRS 1 Chapter 3), gathers the roughly 1,100 ESRS data points across the twelve standards, and acts as the interface to the financial auditor since the report is subject to mandatory assurance, limited now and reasonable in the medium term. Reports follow the European Single Electronic Format (ESEF) with XBRL tagging against the ESRS taxonomy. In parallel the officer aligns the EU Taxonomy Regulation 2020/852, the SFDR Regulation 2019/2088 for financial institutions and the LkSG supply chain duties, which requires structured data flows across Finance, Procurement, HR and Operations.
Duties of the ESG officer
- Conduct the double materiality assessment under ESRS 1 with both impact and financial perspectives.
- Build and maintain the ESRS data point inventory (around 1,100 quantitative and qualitative data points).
- Prepare the sustainability statement within the management report under Art. 19a and 29a of the Accounting Directive as amended by the CSRD.
- Calculate taxonomy eligibility and alignment under Art. 8 of EU Taxonomy Regulation 2020/852.
- Compute Scope 1, 2 and 3 greenhouse gas emissions under GHG Protocol and ESRS E1.
- Coordinate with LkSG reporting to the Federal Office for Economic Affairs and Export Control (BAFA) under § 10 LkSG.
- Map CSRD requirements against existing frameworks (GRI, SASB, TCFD, ISSB IFRS S1/S2).
- Prepare the assurance engagement on the sustainability statement, including the audit trail.
- Train operational data providers in procurement, HR, production and finance.
- Report to the management board, supervisory board and audit committee on risks, opportunities and target achievement.
Appointment and audit obligation
Unlike the data protection officer or the AML officer, the sustainability officer is not codified in a single statute. The obligation arises indirectly from the legal representatives' responsibility for the management report under § 264 HGB, the risk monitoring duty under § 91 Para. 2 AktG, the assurance duty of the CSRD itself and the D&O liability exposure for incorrect reporting. No German transposing provision exists yet. Because the sustainability statement forms part of the management report and is subject to mandatory assurance, most in-scope companies establish a dedicated C-level or senior leadership role. Audits initially follow ISAE 3000 (Revised) or the forthcoming European Sustainability Reporting Assurance Standard (ESRAS). § 107 Para. 3 sentence 2 AktG so far lists the financial reporting process, the internal control, risk management and internal audit systems and the statutory audit for the audit committee, not sustainability reporting; § 107 Para. 4 AktG only requires public-interest entities to have an audit committee at all. Until transposition the supervisory board therefore has to assign responsibility for the sustainability statement in the committee mandate itself.
Typical qualifications include a business or engineering background, expertise in greenhouse gas accounting under the GHG Protocol and ISO 14064, fluency with the ESRS standards, and ideally a certification such as GRI Certified Sustainability Professional, IFRS Sustainability Reporting Certificate or CSE Certified Sustainability Practitioner. Multi-year experience in data management, risk analysis and stakeholder engagement is standard. External appointments are common in mid-market Wave 2 companies, often as interim sustainability officer at 2 to 4 days per month, while Wave 1 groups usually maintain internal teams embedded in Finance, Strategy or a dedicated sustainability unit, typically supported by an ESG steering committee with CFO, CHRO and COO.
- Wave 1: listed companies above 500 employees, reporting year 2024 (former NFRD scope).
- Wave 2: all large undertakings under § 267 HGB, reporting year 2027 after the postponement by Directive (EU) 2025/794 (at least two of: 25M EUR balance sheet, 50M EUR turnover, 250 employees).
- Wave 3: listed SMEs, reporting year 2028 under Directive (EU) 2025/794.
- Third-country undertakings with more than 150M EUR EU turnover and EU subsidiary or branch from 2028.
- LkSG-obliged companies from 1,000 employees in Germany with BAFA reporting under § 10 LkSG.
- Contractual triggers: sustainability-linked loans, OEM supplier self-assessments, investor SFDR reporting.

How CIVAC supports the ESG officer
CIVAC offers a CSRD-ready workspace with an ESG data point tracker for the ~1,100 ESRS data points, a double materiality matrix following ESRS 1 Chapter 3 and a CSRD pre-audit report formatted as auditors expect for limited assurance under ISAE 3000. The platform maps ESRS to GRI, SASB and ISSB IFRS S1/S2 so parallel investor reports avoid double data entry. The taxonomy module computes eligibility and alignment under Art. 8 of Regulation 2020/852 for turnover, CapEx and OpEx. Scope 1, 2 and 3 emissions are calculated against GHG Protocol with built-in emission factors from DEFRA, UBA and ecoinvent. The integrated LkSG block exports straight to the BAFA portal under § 10 LkSG. The audit trail meets the 10-year retention under § 257 HGB.
