Circular Economy and ESG Reporting
Where circularity meets corporate disclosure
Circular economy performance is increasingly expected to be disclosed in corporate sustainability reports. The EU Corporate Sustainability Reporting Directive (CSRD) and its European Sustainability Reporting Standards (ESRS) require large companies to report on material topics including resource use, waste, and circular economy. Understanding how circularity integrates into ESG reporting frameworks, and what metrics investors and regulators expect, is now essential knowledge for sustainability professionals.
Why Circular Economy Is an ESG Issue
ESG (Environmental, Social, and Governance) analysis evaluates a company's sustainability performance and associated risks across three dimensions. The circular economy is most directly an environmental (E) issue, but it also has strong social (S) and governance (G) dimensions. On the environmental side, resource use efficiency, waste generation, recycled content, and product end-of-life management are all material topics for companies in manufacturing, retail, construction, food, and many other sectors.
Social dimensions of circularity include fair labour conditions in collection and recycling supply chains, equitable distribution of circular economy benefits, and the just transition for workers in industries moving from linear to circular models. Governance dimensions include board oversight of circular economy strategy, supplier due diligence on circular practices, and internal incentive structures that reward circular innovation rather than short-term linear cost optimization.
Analogy: The Business Balance Sheet Extended
A traditional balance sheet captures a company's financial assets and liabilities but not its natural capital assets (the materials and ecosystems it depends on) or its natural capital liabilities (the waste and pollution it creates). ESG reporting and circular economy disclosure extend the balance sheet concept to natural capital: companies must account for their material dependencies, resource efficiency, and waste liabilities just as they account for financial assets and debts. Investors increasingly use this extended balance sheet to assess long-term business resilience.
CSRD and ESRS: The EU Mandatory Framework
The Corporate Sustainability Reporting Directive (CSRD) entered into force in January 2023, requiring a first wave of large EU-listed companies to report under its provisions for financial years beginning in 2024. The CSRD replaces the Non-Financial Reporting Directive (NFRD) and dramatically expands both the scope of companies required to report and the depth of information required.
The European Sustainability Reporting Standards (ESRS) define exactly what companies must disclose. ESRS E5 specifically addresses "Resource Use and Circular Economy." Its requirements include disclosure of:
- Resource inflows: total material consumption, proportion from recycled or renewable sources, water withdrawal volumes.
- Resource outflows: products and materials designed for circularity, proportion of products sold that are designed to be recyclable or reusable, take-back volumes.
- Waste: total waste generated by weight and type, waste diverted from disposal, waste sent to disposal by disposal route.
- The company's circular economy strategy, targets, and governance arrangements.
GRI Standards and Circular Economy
The Global Reporting Initiative (GRI) Standards are the most widely used voluntary sustainability reporting framework globally. The GRI 306 (Waste) Standard (2020) requires companies to disclose waste generation data, waste diversion from disposal (through recycling, composting, and reuse), and waste directed to disposal. GRI 301 (Materials) covers material inputs and recycled input fractions.
These GRI disclosures are compatible with ESRS E5 requirements and companies reporting under GRI typically have data infrastructure that facilitates CSRD compliance. However, GRI reporting does not include the circular economy strategy narrative and governance disclosure that ESRS E5 requires, so CSRD-compliant companies will need to supplement their existing GRI data with strategic context.
Industry Example: Circular Economy Reporting in Fashion
A large EU clothing brand subject to CSRD would be required to disclose under ESRS E5: the total weight of materials used in production (and the recycled or renewable fraction); the percentage of garments sold that are designed for recyclability; volumes returned through take-back schemes and their subsequent processing; total waste generated at manufacturing sites; and packaging waste. The brand would also be expected to describe its circular economy strategy, including targets for recycled content, take-back expansion, and design for longevity. This level of disclosure enables investors, customers, and regulators to compare the brand's circular performance against peers and against its own stated targets over time.
Connecting Circularity to Financial Risk
Investors increasingly recognise that circular economy performance is a proxy for business resilience. Companies heavily dependent on virgin raw material inputs face transition risk as resource prices increase, regulations tighten, and carbon costs are introduced along material supply chains. Companies with high waste generation face regulatory risk as landfill restrictions tighten and EPR obligations expand. Circular business models, by contrast, tend to reduce these material and regulatory risks.
Credit rating agencies, asset managers, and institutional investors increasingly incorporate circular economy metrics into their due diligence processes. The EU Taxonomy Regulation's substantial contribution criteria for the circular economy objective define which economic activities are taxonomically sustainable in circularity terms, directing green finance toward truly circular activities and creating a risk-adjusted premium for circular business models.
| Reporting Framework | Circular Economy Relevance | Key Disclosures |
|---|---|---|
| ESRS E5 (CSRD) | Mandatory for large EU companies | Resource inflows, outflows, waste, circular strategy |
| GRI 301 Materials | Widely used voluntary standard | Material weight, recycled input fraction |
| GRI 306 Waste | Widely used voluntary standard | Waste by type, diversion and disposal routes |
| EU Taxonomy | Mandatory for in-scope financial entities | Revenue, capex, opex aligned to CE objective |
| TCFD (physical risk) | Voluntary but widely adopted | Resource scarcity as physical risk driver |
CSRD requires companies to conduct a "double materiality" assessment before determining what to report. Double materiality has two dimensions: financial materiality (how sustainability issues affect the company's financial performance and position) and impact materiality (how the company affects the environment and society through its activities).
For circular economy topics, double materiality analysis might reveal that: virgin material dependency creates financial materiality (cost and supply risk), while waste generation and product end-of-life create impact materiality (environmental harm). Both dimensions must be reported if material. Companies that have not previously considered circular economy in their materiality assessments often find it becomes material under CSRD's broader and more rigorous methodology, requiring them to develop new data collection systems and management processes.
Key Takeaways
- 1Circular economy performance is increasingly required in corporate sustainability reporting, most significantly under the EU CSRD and its ESRS E5 standard on Resource Use and Circular Economy
- 2ESRS E5 requires large EU companies to disclose resource inflows (including recycled fraction), resource outflows (including products designed for circularity), waste data, and circular economy strategy and governance
- 3GRI 301 (Materials) and GRI 306 (Waste) are widely used voluntary standards compatible with ESRS requirements and provide the data foundation for CSRD compliance
- 4Investors use circular economy metrics as proxies for business resilience: companies dependent on virgin inputs face transition risk, while circular models reduce material and regulatory risk exposure
- 5CSRD requires a double materiality assessment identifying both financial materiality (circular economy risk to the company) and impact materiality (company's impact on environment through resource use and waste)
