What ESG Stands For: E, S, and G Explained in a Business Context

ESG is an abbreviation for three English terms: Environmental, Social, and Governance. Originally rooted in capital markets language, the acronym has acquired legally binding significance through the Corporate Sustainability Reporting Directive (CSRD, EU 2022/2464) and the associated European Sustainability Reporting Standards (ESRS): from the financial year 2025, capital-market-oriented companies with more than 500 employees are required to produce sustainability reports under ESRS; large non-capital-market-oriented companies with 250 or more employees follow from 2026.

This article explains the three ESG dimensions concretely, shows which individual standards — CSRD, ESRS, LkSG, Money Laundering Act (GwG), GDPR — underlie them, and describes what an ESG or Sustainability Officer must organise within the company so that reporting obligations, due diligence obligations, and stakeholder requirements can be met in a structured manner.

The E in ESG stands for Environmental and covers all aspects of a company's relationship with the natural environment. In the ESRS framework, environmental topics are codified in five specific standards: ESRS E1 (Climate Change), ESRS E2 (Pollution), ESRS E3 (Water and Marine Resources), ESRS E4 (Biodiversity and Ecosystems), and ESRS E5 (Resource Use and Circular Economy).

For most medium-sized companies, ESRS E1 and E5 are the most immediately relevant. ESRS E1 requires disclosure of greenhouse gas emissions under the Greenhouse Gas Protocol (Scope 1, 2, 3), climate risks, and decarbonisation plans in line with the Paris Climate Agreement. ESRS E5 requires information on material flows, waste volumes, and measures to extend product life cycles.

Outside CSRD, further legal requirements exist in the environmental dimension: the Environmental Officer under the BImSchG and WHG monitors emissions and water protection; the Waste Management Officer under § 59 KrWG is responsible for the waste prevention strategy; the Emissions Protection Officer under § 53 BImSchG reports annually to the authority. These functions feed substantively into the ESG report and should be coordinated.

The Supply Chain Due Diligence Act (LkSG) supplements the environmental dimension with the obligation to identify and mitigate environment-related risks in the supply chain. From 2024, LkSG applies to companies with 1,000 or more employees; BAFA reviews the risk reports.

More on the operational implementation of the environmental dimension can be found on the CIVAC page on the ESG Sustainability Officer.

The S in ESG stands for Social and covers the impact of a company on people inside and outside the business: its own workforce, the supply chain, affected communities, and consumers.

In the ESRS framework, social topics are regulated in four standards: ESRS S1 (Own Workforce), ESRS S2 (Workers in the Value Chain), ESRS S3 (Affected Communities), and ESRS S4 (Consumers and End Users). ESRS S1 is the most relevant standard for most companies; it requires information on working conditions, collective bargaining coverage, equal treatment, diversity, health and safety at work, and corporate culture.

In national law, the social requirements are reflected in several standards: the General Equal Treatment Act (AGG) prohibits discrimination and requires organisations to establish a complaints office under § 13 AGG. LkSG requires evidence for the company's own supply chain that no violations of ILO core labour standards (e.g. child labour, forced labour) are occurring. The Whistleblower Protection Act (HinSchG) is also a social-governance instrument, as it establishes reporting channels for violations.

For the ESG report under ESRS S1, specific quantitative disclosures are required: employee count by gender and contract type, sickness absence rate, accident frequency (accident days per 1 million working hours), training hours per employee, and proportion of employees under collective agreements. These metrics must be consolidated from HR and occupational health and safety systems.

The G in ESG stands for Governance and refers to the structures and processes by which a company is directed and controlled. In the ESRS framework, Governance is regulated in ESRS G1 (Business Conduct, Risk Management, and Internal Control).

ESRS G1 requires, among other things, disclosures on the governance structure (composition and diversity of the management body), risk management systems, anti-corruption and anti-bribery measures, lobbying and political engagement, and payments to public bodies. In concrete terms, this means for many medium-sized companies that a structured description of the internal control system (ICS) must for the first time be made publicly available.

In national law, governance requirements correspond to several officer roles: the Compliance Officer under IDW PS 980 and § 130 OWiG monitors rule compliance; the Data Protection Officer under Art. 37 GDPR secures data protection governance; the Anti-Money Laundering Officer under § 7 GwG monitors transaction risks; the Information Security Officer under ISO/IEC 27001:2022 and §§ 30, 38 BSIG is responsible for IT governance.

All these officer roles supply data points for the ESRS G1 report. The ESG Officer coordinates these contributions and ensures the report is consistent and audit-ready. Without this coordination, reporting gaps arise that the external auditor will raise in the Limited Assurance review.

More on the governance roles in the CIVAC platform can be found on the Compliance Officer page.

The Corporate Sustainability Reporting Directive (CSRD, EU 2022/2464) entered into force on 5 January 2023 and was transposed into German law through the CSR Directive Implementation Act into the Commercial Code (HGB, §§ 289b–289e, 315b–315c HGB as amended). CSRD replaces the previous Non-Financial Reporting Directive (NFRD) and considerably extends the circle of companies subject to reporting obligations.

The timetable is phased: public interest entities (PIEs) with 500 or more employees report for the first time for the financial year 2024 (publication 2025). Large companies with 250 or more employees, a balance sheet total of more than €20 million, or turnover of more than €40 million report for the first time for financial year 2025 (publication 2026). Small and medium-sized capital-market-oriented companies follow from financial year 2026, with an opt-out option until 2028.

The reporting content is defined by the ESRS (European Sustainability Reporting Standards), developed by EFRAG and enacted by the European Commission as delegated legal acts. The ESRS comprise two cross-cutting standards (ESRS 1: General Requirements, ESRS 2: General Disclosures) and ten thematic standards (E1–E5, S1–S4, G1). Which thematic standards must be reported depends on a double materiality assessment: companies must assess which sustainability topics are material for them from an impact perspective and from a financial risk perspective.

The sustainability report is part of the (consolidated) management report and is subject to external audit with limited assurance under §§ 317 para. 3b, 322 HGB as amended.

Double materiality is the central concept of the ESRS framework and distinguishes ESG reports under CSRD from earlier sustainability reports. It requires companies to assess sustainability topics from two perspectives.

The inside-out perspective (impact materiality) asks: what actual or potential impacts does the company have on people and the environment? A chemicals company that discharges wastewater has considerable environmental impact; a service company with a large workforce has considerable social impact on its employees.

The outside-in perspective (financial materiality) asks: which sustainability risks and opportunities have financial implications for the company? Rising carbon prices are a financial risk for emission-intensive businesses; regulatory requirements for supply chains are a financial risk for importers from high-risk countries.

Only topics assessed as material from at least one perspective must be reported in full. This materiality assessment must be documented in a traceable manner and regularly updated. The external auditor also reviews the appropriateness of the materiality process as part of the Limited Assurance review.

For the ESG Officer, the materiality analysis is one of the most demanding tasks: it requires knowledge of the ESRS, a structured stakeholder survey, and a quantitative risk assessment. The CIVAC workspace provides 37 ready-to-use audit templates for this purpose, including templates for materiality assessment under ESRS 1.

The Supply Chain Due Diligence Act (LkSG) has been in force since January 2023 for companies with 3,000 or more employees, and since January 2024 for companies with 1,000 or more employees. It requires the carrying out of a risk analysis under § 5 LkSG, the establishment of a complaints procedure, and annual reporting to the Federal Office for Economic Affairs and Export Control (BAFA).

LkSG and CSRD are complementary but cover different areas. LkSG focuses on human rights and environment-related due diligence in the supply chain; CSRD additionally requires comprehensive sustainability reporting across all E, S, and G topics. Companies subject to both regimes should coordinate the LkSG risk analysis and the ESRS materiality analysis to avoid duplication.

The ESG Officer typically coordinates between the LkSG Officer, who is responsible for operational supply chain monitoring, and the reporting team creating the ESRS report. Without this coordination, there is a risk that LkSG findings do not feed into the ESRS report and the report is thus incomplete.

The BAFA report under § 10 LkSG has its own formal requirements that differ from ESRS requirements. The substantive overlaps lie particularly with ESRS S2 (Workers in the Value Chain) and ESRS E2 (Pollution in the Supply Chain). A coordinated data pathway serving both requirements significantly reduces the collection burden.

Further information on the operational linkage of CSRD and LkSG can be found on the CIVAC page on the ESG Sustainability Officer.

An ESG or Sustainability Officer is not prescribed in any single legal standard, but is in practice indispensable given the combination of CSRD, ESRS, LkSG, and the associated reporting and audit obligations. The question is not whether but how this function is filled.

The tasks of the ESG Officer include: carrying out and documenting the double materiality analysis under ESRS 1; coordinating data collection across all ESG dimensions from specialist departments and officer roles; managing the external audit process (Limited Assurance); liaising with investors, lenders, and suppliers; and monitoring legislative changes in the ESG area.

Qualification requirements are not defined by statute but have emerged in practice: knowledge of ESRS and the CSRD framework; basic knowledge of financial reporting (since the sustainability report forms part of the management report); knowledge of LkSG and BAFA requirements; and experience in project management across departmental boundaries.

Many companies reach the limits of their internal capacity when building ESG reporting for the first time. The option of appointing an external ESG Officer who takes on the coordination and supports the development of internal processes is in this context both practical and cost-efficient. Instrument of appointment, signed, filed, evidenced — this standard also applies to the ESG role.

ESG has for companies not only a regulatory dimension but also a capital markets and credit dimension. Banks and institutional investors are required by the EU Taxonomy Regulation (EU 2020/852) and the Sustainable Finance Disclosure Regulation (SFDR, EU 2019/2088) to take sustainability risks into account in their investment and lending decisions.

Credit institutions are increasingly asking their corporate clients for ESG metrics in order to assess climate risks in their lending portfolios (EBA Guidelines on Loan Origination and Monitoring, EBA/GL/2020/06). Companies without structured ESG data may experience disadvantages in credit terms or interest rates. This affects medium-sized companies that are not yet formally subject to CSRD but are already receiving ESG questionnaires from their banks.

ESG ratings are issued by specialist agencies (MSCI, Sustainalytics, ISS-ESG), which produce assessments on the basis of public information and company questionnaires. These ratings influence inclusion in ESG-compliant indices, the decisions of institutional investors, and credit conditions. A structured ESG report under ESRS improves the data base for these ratings and reduces the risk of downgrading due to insufficient disclosure.

For suppliers to large companies, ESG pressure comes from the other direction: large corporate customers and groups request sustainability data from their suppliers as part of their own CSRD and LkSG obligations. Companies that cannot provide structured ESG data risk losing supplier qualifications.

Companies building ESG reporting for the first time or wishing to bring their existing practice up to CSRD level should proceed in three phases.

In the first phase, the focus is on stocktaking: which reporting obligations apply to the company (CSRD timetable, LkSG threshold, sector-specific requirements)? Which officers have already been appointed and supply ESG-relevant data? Which data gaps exist for the ESRS requirements?

In the second phase, the materiality analysis under ESRS 1 is conducted: structured stakeholder survey, assessment of impact and financial materiality, documentation of results. The outcome of the materiality analysis defines the scope of the report and thereby the effort for data collection.

In the third phase, the reporting infrastructure is built: data pathways from specialist departments and officers into a central reporting system; processes for data validation and versioning; and preparation for the external Limited Assurance audit.

The CIVAC workspace supports all three phases as an integrated platform function. The 37 ready-to-use audit templates cover materiality assessment, ESRS checklists, and LkSG risk analysis. Licence the workspace for your internal officers or commission our officers — both models use the same platform.

Others manage compliance like a filing cabinet. We manage it like software.
