Speak circular fluently.

The practice of keeping materials, products and the value embedded in them in use at their highest possible value, for as long as possible, and designing out waste from the start. Circularity is not recycling. Recycling is the last resort, recovering material after value has already been destroyed. Circularity is a business system: how value is created, retained and recovered across a supply chain.

An economic model in which growth is decoupled from the consumption of finite resources. Products and materials cycle through use, reuse, repair, remanufacture and recovery instead of ending as waste. It replaces the linear economy and depends on multi-actor supply chains where every actor understands their role in closing the loop, and profits from it.

The dominant model today: take, make, use, discard. Value is extracted once and lost. The Circularity Gap Report 2026 estimates the avoidable value lost to linear practices at €25.4 trillion a year, almost a third of global GDP. (See Value Gap.)

The organisational capability to understand, prioritise, and operationalise circularity as a business system — integrating people, processes, data, incentives, and decisions into scalable execution. It is what gets built inside organisations. The company is named after the capability, not the other way around.

The commercial upside of circularity done properly: resilience against material scarcity and price volatility, cost recovery, new revenue models, regulatory positioning and access to capital. The opposite of circularity as a cost centre.

Whether an organisation is actually built to execute circular initiatives at scale. Most circular strategies fail not because the strategy is wrong but because the organisation isn't ready to implement it. Ambition is abundant. Readiness is scarce.

A five-level maturity model showing where an organisation actually stands on circularity, whether it got there in a healthy sequence, and why progress is stalling. Both a maturity ladder and a sequencing diagnostic. (See CRL1, CRL2, CRL3, CRL4, CRL5.)

People across the organisation understand what circularity means, why it matters, and how it connects to the business. The foundation every subsequent level depends on. Most organisations skip it.

The organisation responds to external regulatory and reporting pressure: CSRD, ESRS, ESG frameworks, extended producer responsibility. Most organisations land here first, often before CRL1 is real. Compliance matters, but on its own it does not create readiness.

Circularity becomes something people act on internally. Champions emerge, feedback loops influence decisions, management gains visibility into where momentum exists and where it does not.

Circularity is built into governance, systems, data structures, investment logic and decision-making. No longer dependent on motivated individuals. The organisation is structurally set up to hold it.

Circularity is supported beyond the organisation itself. Value chains, standards bodies, regulators and industry structures are aligned enough for circular models to work at scale. The systemic condition circularity needs to become durable.

The most common failure pattern in circular transitions. External pressure forces a compliance response before shared understanding exists. The result: reporting on paper, weak adoption in practice, and circular strategies that stall the moment they leave pilot conditions.

The EU directive requiring large companies to report on sustainability. After the Omnibus simplification, the mandatory threshold sits at 1,000 employees and €450 million turnover. Below it, reporting is voluntary, which changes the question from obligation to advantage.

The European Sustainability Reporting Standard covering resource inflows, resource outflows and circular design across the value chain, disclosed through requirements E5-1 to E5-5. For most companies it is now a choice rather than a mandate.

The assessment logic behind ESRS: a topic is material if the company affects it (impact materiality) or if it affects the company financially (financial materiality). It determines whether circular economy topics must be disclosed.

The EU's flagship circularity law in the making, with the Commission's legislative proposal expected in the second half of 2026. Positioned as a central pillar of the Clean Industrial Deal, it aims to establish a Single Market for secondary raw materials and double the EU's circular material use rate to 24% by 2030. The signal matters more than the text: circularity is now industrial policy, not environmental policy. (See Circular Material Use Rate, End-of-waste criteria.)

The EU's 2020 strategy under the European Green Deal that set the current policy direction: ecodesign, product passports, waste reform, sector roadmaps. The Circular Economy Act builds on it and hardens it into law.

In force since July 2024. It sets binding requirements for durability, repairability, recycled content and recyclability across product groups, and is the legal home of the Digital Product Passport. The regulation that moves circularity from reporting into product design.

A structured digital record travelling with a product through its life: materials, origin, repairability, recycled content, compliance data. Being rolled out under the ESPR, and a practical test of whether an organisation's data structures are circular-ready.

EU regulation setting binding recyclability, reuse and recycled-content requirements for all packaging on the EU market. One of the first places where circular design stops being optional.

Regulation that makes producers responsible for their products after use, including collection, recycling and end-of-life costs. A major driver pushing organisations into CRL2.

Applies from 31 July 2026, requiring manufacturers to repair goods within a reasonable time and at a reasonable price. It extends product responsibility deep into the use phase.

EU regulation setting targets for domestic extraction, processing and recycling of critical raw materials. The clearest expression of circularity as supply security. (See Critical Raw Materials.)

Due diligence regulation requiring proof that commodities such as coffee, cocoa, timber and rubber are deforestation-free and traceable to the plot of origin. A preview of where all supply chain regulation is heading: claims backed by verifiable data, not declarations.

The EU's carbon price on imported goods in high-emission sectors. Primarily a climate instrument, but it indirectly rewards recycled and lower-carbon material inputs, strengthening the business case for circular sourcing.

The EU's classification system for sustainable economic activities. Transition to a circular economy is one of its six environmental objectives, which links circular performance directly to access to capital.

Proposed EU rules requiring environmental claims to be substantiated and verified before use. Its final form is still moving through the EU process, but the direction is settled: unproven circularity claims are becoming a legal liability, not a marketing risk.

The 2025 EU package that cut sustainability reporting obligations, raised the CSRD threshold to 1,000 employees and €450 million turnover, and reduced ESRS E5 data points by roughly 60%. It made circularity reporting voluntary for most companies, which changed the question from obligation to advantage.

The legal conditions under which a material stops being waste and becomes a product again. Currently fragmented across member states, and one of the biggest practical barriers to a functioning secondary materials market. Harmonising these criteria is a stated focus of the Circular Economy Act.

The first global voluntary framework for measuring, managing and communicating corporate circular performance, launched at COP30 in November 2025 by WBCSD and the UNEP-hosted One Planet Network. Built on the Circular Transition Indicators and aligned with GRI, ISO 59020, ESRS and IFRS S1/S2. Doing for circularity what the GHG Protocol did for emissions.

WBCSD's company-level framework for measuring circular material flows: percentage inflow and outflow circularity, water and energy circularity. The measurement engine underneath the Global Circularity Protocol.

The Global Reporting Initiative's waste standard, requiring disclosure of waste generation, diversion and disposal across the value chain. The most widely used waste disclosure baseline globally, and a common interoperability point with ESRS E5.

The first international standards family for the circular economy, covering principles and terminology (ISO 59004), business models (ISO 59010) and measurement (ISO 59020). It gives organisations a shared, auditable language for circular claims.

The EU's simplified voluntary reporting standard for companies below the CSRD threshold. Distinct from voluntarily applying the full ESRS: different instrument, different depth. Choosing between them is a strategic decision, not an administrative one.

The international baseline for investor-facing sustainability disclosure. No circular-specific standard yet, but resource-related risks fall under S1, and interoperability with ESRS is where most multi-jurisdiction reporters feel the friction.

The share of material used in an economy that comes from recycled sources, published by Eurostat. The EU-27 average is around 12%, a figure that has barely moved in fifteen years. The Netherlands leads Europe at over 30%; several member states sit below 5%. The Circular Economy Act targets 24% by 2030.

The distance between how circular the global economy is and how circular it needs to be. The world is 6.9% circular, and falling: down from 9.1% in 2018. The gap is not a technology problem. It is a coordination and readiness problem.

Introduced in the Circularity Gap Report 2026: the avoidable economic value lost each year to linear material use, initially estimated at €25.4 trillion, almost a third of global GDP. For every three euros of value created, roughly one is lost. It translates linearity from an environmental problem into a balance-sheet problem.

Quantified environmental impact analysis across a product's full life cycle, extended to account for reuse, recovery and multiple use cycles. The evidence layer under credible circular claims.

The materials the EU classifies as economically vital and supply-constrained, currently 34 of them. Circularity is increasingly a supply-security strategy: recovered materials are the only domestic mine most of Europe has.

A metric, not a claim. A score describes measured material flows under a chosen methodology. It becomes a claim only when it is traceable, comparable and able to survive assurance. The difference is where most greenwashing risk lives.

The hierarchy of circular strategies, from highest to lowest value retention: refuse, rethink, reduce, reuse, repair, refurbish, remanufacture, repurpose, recycle, recover. The higher the strategy sits, the more value is retained. Most “circular” activity today happens at the bottom rungs.

The core economic logic of circularity: keeping products, components and materials at their highest useful value instead of degrading them to raw material or waste.

Materials recovered from products, by-products or waste and returned to productive use in place of virgin inputs. Creating a functioning Single Market for them is the central objective of the EU Circular Economy Act.

Recycling that degrades material quality, so the output can only serve lower-value applications. Common in plastics and textiles. The gap between recycling rates and actual circularity is largely a downcycling problem.

The infrastructure for getting products and materials back: collection, return, sorting, redistribution. Its absence is one of the most common system-level ceilings organisations hit at CRL4.

A programme through which producers or retailers recover their products after use, voluntarily or under EPR obligations. The front door of reverse logistics.

A circular business model in which customers pay for access or performance rather than ownership, and the producer retains the asset. It aligns the producer's incentive with durability and recovery, because the product coming back is the business model.

Cooperation between companies in which one organisation's residual output (materials, energy, water) becomes another's input. Circularity at district and industrial-park scale.

Recovering valuable materials from the existing built environment and product stock: buildings, infrastructure, electronics. Treating the city as a material depot rather than a waste source.

Designing products and buildings so components and materials can be separated cleanly at end of use. The upstream decision that determines whether downstream recovery is economically viable. Increasingly paired with a Digital Twin so the disassembly logic is captured as data, not lost in a set of drawings.

A live digital replica of a physical asset — a building, a bridge, a factory, a piece of infrastructure — kept in sync with the real thing through BIM models, sensor data and lifecycle records. In a circular context the twin is the memory of what a building is made of, where the components came from, how they were joined and how they can come apart again. It turns a structure from a black box at end of life into a mapped stock of recoverable materials, and is the bridge between design for disassembly, urban mining and the Digital Product Passport. Institutes such as TNO develop the underlying standards and predictive twin research for the built environment.

The condition where value chains, standards, regulators and infrastructure are coordinated enough for circular models to work at scale. No single organisation can be circular alone; circular problems are systemic and cannot be solved from within a single node.
