Summary: ESG metrics are the indicators that show how well a company manages environmental, social, and governance performance across operations and the supply chain. For supply chain and ESG teams, the challenge is not simply collecting more data but selecting metrics that align with industry risk, regulatory obligations, and decision-making needs under frameworks such as CSRD, CSDDD, and LkSG. Useful ESG metrics turn broad sustainability goals into measurable actions, comparable performance, and defensible disclosures.
Table of contents
ESG metrics are quantitative and qualitative indicators that measure a company’s performance across Environmental, Social, and Governance dimensions — and in 2025–2026, tracking the right ones is no longer optional. Regulatory frameworks including the EU Corporate Sustainability Reporting Directive (CSRD), the EU Corporate Sustainability Due Diligence Directive (CSDDD), and Germany’s Supply Chain Due Diligence Act (LkSG) now legally require companies to assess, report, and act on ESG data across their entire value chain. With companies under growing pressure from investors, customers, and regulators, the question is no longer whether to track ESG metrics — but whether you are tracking the right ones for your industry and compliance obligations.
What are ESG Metrics?
ESG metrics are a set of indicators used to measure a company’s Environmental, Social, and Governance performance across its operations and supply chain. The ‘E’ (Environmental) dimension measures a company’s impact on the natural world, including greenhouse gas emissions, energy consumption, water usage, waste management, and biodiversity. The ‘S’ (Social) dimension measures a company’s impact on people, including human rights practices, employee health and safety, supply chain labor standards, and product safety — areas now directly addressed by CSDDD and LkSG due diligence obligations. The ‘G’ (Governance) dimension measures internal controls and accountability, including board diversity, executive compensation, anti-corruption policies, and business ethics. Together, these three pillars provide a comprehensive picture of a company’s sustainability risk exposure and long-term resilience.
Examples of ESG Metrics
ESG metrics can be broken down into three main categories: Environmental, Social, and Governance. Here are key examples for each category, aligned with leading frameworks such as GRI, SASB, and the CSRD European Sustainability Reporting Standards (ESRS):
Environmental:
- Greenhouse gas emissions (Scope 1, 2, and 3)
- Carbon footprint across the supply chain
- Energy consumption and intensity
- Water usage and water stress exposure
- Waste management and circular economy metrics
- Biodiversity impact and land use
- Product lifecycle analysis
- Energy efficiency improvements year-over-year
- Renewable energy percentage of total consumption
Social:
- Human rights due diligence across supplier tiers (required under CSDDD and LkSG)
- Employee health and safety rates (TRIR, LTIR)
- Diversity, equity, and inclusion metrics
- Supply chain labor standards and forced labor risk
- Product safety and recall rates
- Community engagement and social investment
- Customer privacy and data security incidents
- Philanthropy and charitable giving as a percentage of revenue
Governance:
- Board diversity and structure (gender, independence, skills)
- Executive compensation ratio and alignment with ESG targets
- Anti-corruption policies and whistleblower mechanisms
- Business ethics and code of conduct compliance
- Supply chain risk management processes
- Shareholder rights and engagement
- Political contributions and lobbying disclosure
- Audit quality and financial reporting integrity
- Corporate governance metrics and policy coverage
It’s important to note that these are key examples across major frameworks, and the specific KPIs a company tracks will depend on its industry, size, geographic footprint, and applicable regulatory obligations — including whether the company falls under CSRD, CSDDD, or LkSG reporting thresholds.
Why These Metrics Matter
ESG metrics are critical for businesses for several interconnected reasons. First, measuring and tracking ESG performance enables companies to identify and mitigate material risks — including environmental liabilities, human rights violations in the supply chain, and governance failures — before they translate into financial losses, regulatory fines, or reputational damage. Under the EU CSDDD, which entered into force in 2024, large companies must actively identify, prevent, and address adverse human rights and environmental impacts across their value chains, making robust ESG measurement a legal imperative, not just a best practice.
ESG metrics also help businesses build trust and credibility with stakeholders — investors, customers, employees, and regulators. By reporting on ESG performance with transparency, companies demonstrate their commitment to responsible business practices and sustainable growth. This is increasingly valued by institutional investors: as of 2025, over $30 trillion in global assets under management are subject to ESG screening criteria, making ESG performance a direct driver of capital access and cost of financing.
ESG metrics are also central to regulatory compliance. The EU’s Corporate Sustainability Reporting Directive (CSRD) requires companies meeting size thresholds to report against the European Sustainability Reporting Standards (ESRS) — which are built around measurable ESG indicators. Similarly, the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), and the European Financial Reporting Advisory Group (EFRAG) all provide sector-specific metric frameworks. Selecting and tracking the right metrics under these frameworks strengthens transparency, accountability, and defensibility in regulatory audits.

Beyond compliance, tracking ESG metrics enables companies to identify emerging opportunities. Businesses that proactively monitor trends in renewable energy adoption, Scope 3 emissions reduction, and sustainable supply chain management are better positioned to develop new products, services, and partnerships that meet evolving market demands. A strong ESG metrics program creates long-term value — both for stakeholders and for the business itself.
How to Calculate ESG Metrics
ESG metrics are calculated using a combination of methods: internal data collection, third-party audits, supplier assessments, and recognized reporting standards. Data is sourced from operational systems (energy bills, HR records, waste manifests), supplier self-assessments, and independent verification. ESG scores are often derived by aggregating and weighting individual metrics — for example, combining Scope 1 and Scope 2 emissions data, supplier labor audit results, and board composition metrics into a composite score. Under frameworks such as the GRI Standards and CSRD’s ESRS, many calculations follow standardized methodologies to ensure comparability across companies and reporting periods. Certainty Software’s audit and inspection platform helps organizations systematically collect, calculate, and report ESG data across their supplier networks, ensuring data quality and audit-readiness.
Selecting the Right Metrics
The ESG metrics most relevant to your organization will depend on your industry, operational footprint, regulatory jurisdiction, and the materiality of specific sustainability issues to your business model. A manufacturing company with a complex global supply chain will prioritize different metrics than a financial services firm — but both will need to address supply chain due diligence requirements under CSDDD if they operate at scale in the EU.
Several reporting frameworks provide structured guidance for metric selection. The Global Reporting Initiative (GRI) offers comprehensive universal and sector-specific standards widely used for stakeholder reporting. The Sustainability Accounting Standards Board (SASB) provides industry-specific financially material metrics favored by investors. The European Financial Reporting Advisory Group (EFRAG) governs the ESRS standards under CSRD, which are now mandatory for in-scope EU companies. Aligning your metric selection to the appropriate framework — based on your regulatory exposure and stakeholder expectations — ensures that you are tracking data that is both meaningful and compliant.
How to leverage your ESG Metrics
Collecting ESG data is only the first step — the real value lies in leveraging metrics to drive decisions, improve supplier performance, and communicate credibly with stakeholders. Companies should use their ESG KPIs to benchmark against industry peers, set improvement targets, and track progress over time. In the context of supply chain due diligence, ESG metrics collected through supplier audits and assessments should feed directly into risk prioritization and corrective action workflows. Using a structured tool such as Certainty Software’s ESG Checklist helps companies transform raw ESG data into reportable, actionable intelligence — whether for internal decision-making, investor disclosure, or regulatory reporting under CSRD or LkSG.

Frequently Asked Questions (FAQs)
What is the difference between ESG metrics and ESG ratings?
ESG metrics are the individual data points a company measures and reports — such as carbon emissions, supplier audit scores, or board gender diversity. ESG ratings are external scores assigned by third-party agencies such as MSCI, Sustainalytics, or FTSE Russell, which aggregate and weigh multiple metrics to produce a comparative assessment. Companies should focus on building robust internal metric tracking first; strong underlying data will naturally improve third-party ratings over time.
Which ESG metrics are required under CSRD?
The EU Corporate Sustainability Reporting Directive (CSRD), implemented through the European Sustainability Reporting Standards (ESRS), mandates disclosure across environmental topics (climate, pollution, water, biodiversity, circular economy), social topics (own workforce, workers in the value chain, affected communities, consumers), and governance topics (business conduct). Supply chain-specific metrics — including supplier human rights due diligence, Scope 3 emissions, and value chain environmental impact — are central to CSRD/ESRS reporting requirements.
How do ESG metrics relate to supply chain due diligence under CSDDD and LkSG?
The EU CSDDD and Germany’s LkSG both require companies to identify, prevent, and remediate adverse human rights and environmental impacts in their supply chains. ESG metrics are the measurement foundation for this process: supplier social compliance scores, human rights audit results, environmental impact assessments, and corrective action completion rates are all ESG metrics that directly evidence due diligence program effectiveness and regulatory compliance.
How often should companies update their ESG metrics?
Most regulatory frameworks require annual ESG reporting, but effective ESG management requires more frequent data collection. Supplier audit scores and environmental performance data should ideally be updated quarterly or after significant operational changes. Real-time monitoring through platforms like Certainty Software allows companies to identify emerging risks between formal reporting cycles and take corrective action before issues escalate.
