A global circularity protocol for businesses has launched its first reporting framework, according to Trellis Group, a sustainability media outlet covering corporate resource management and disclosure policy. The protocol adds another data-collection option to a market that already hosts at least four established measurement systems.

What does the protocol cover?

Trellis Group's announcement did not include the full technical specification. Based on the headline alone, the framework is positioned as a shared methodology for measuring material circularity across operations and supply chains. Reporting instruments in this space typically require disclosure across four categories: inflows of virgin versus recycled feedstock, product design for durability and recyclability, reverse logistics performance, and end-of-life recovery rates by weight.

What competing frameworks already exist?

The initiative enters a crowded field. The World Business Council for Sustainable Development publishes Circular Transition Indicators, used by more than 60 companies including Volvo, Royal DSM and Solvay. Circle Economy, a Dutch nonprofit, issues the annual Circularity Gap Reporting framework and the companion Circularity Gap Reporting Initiative. The Ellen MacArthur Foundation runs Circulytics, which scores companies on circular enablers and outcomes. ISO 59020, published in late 2024, provides the first international standard on circular economy measurement.

A new entrant must demonstrate either technical differentiation or adoption pull to displace the incumbents or carve out a parallel niche.

How does it fit the regulatory backdrop?

Companies can no longer treat circularity as a voluntary disclosure. The EU's European Sustainability Reporting Standard E5 took effect for first reporting periods starting on or after January 1, 2024, requiring listed companies to disclose resource use, circular economy practices and waste-related targets. California's Senate Bill 54 and Washington's plastic packaging laws require producer responsibility organizations to report recycling and composting rates by weight, with penalties tied to shortfalls. India's Extended Producer Responsibility framework for electronics, vehicles and batteries obliges producers to recover a rising share of products through certified recyclers.

Against that compliance pressure, voluntary frameworks serve two functions: preparing companies for tighter rules and signaling credibility to capital markets.

Who speaks for the protocol?

The Trellis announcement did not name the convening organization, founding corporate signatories, advisory board members or pilot participants. Without those details, adoption credibility remains unverified. Past framework launches have drawn criticism when governance, funding and membership criteria were not disclosed alongside the technical documents.

What happens next?

The protocol's first reporting cycle will be the milestone to watch. Companies that adopt it would produce disclosures within 12 to 18 months of the framework release, allowing comparison with ESRS E5, Circular Transition Indicators and ISO 59020 outputs on the same corporate populations. Whether the protocol secures entry into the European Financial Reporting Advisory Group's interoperability register, or recognition from regulators outside the EU, will determine whether it becomes a parallel option or a primary measurement standard.
