Data input/output methods

• •Manual data entry
• •Bulk upload/export (Excel / CSV)
• •Inbound APIs
• •Outbound APIs

Chemical substance traceability

Chain-of-custody is a continuity capability; composition and substance traceability are depth capabilities. Neither replaces the other.

• •Product–supplier association - Specific products (styles, SKUs, batches) are linked to the suppliers involved in their production.
• •Product composition / component traceability - Products are represented as structured compositions (e.g. components, ingredients) that can be independently traced to upstream sources.
• •Process & substance (chemical) traceability - Substances used in manufacturing processes can be recorded and linked to facilities, process steps, and affected products.

Sustainability Impact categories

Impact data coverage describes which sustainability-related topics a platform can store and manage data for. It does not indicate the quality of the data, the methodology used, or whether impacts meet specific regulatory thresholds.

• •Material attributes - (e.g. fiber type, recycled / biobased content, origin attributes)
• •Life Cycle Assessment (LCA) data - (e.g. environmental footprint indicators at product or material level)
• •Carbon & energy data - (e.g. GHG emissions, energy use, Scope-related data)
• •Water use & wastewater data - (e.g. water withdrawal, consumption, discharge, wastewater treatment data)
• •Chemical impact & compliance data - (e.g. restricted substances, chemical inventories, compliance status)
• •Supplier processes & practices - (e.g. production processes, management systems, operational practices)
• •Human rights & working conditions - (e.g. labor practices, social compliance data)
• •Biodiversity & land use - (e.g. land-use impacts, deforestation-related data)
• •Animal welfare - (e.g. animal-derived materials and related practices)

Types of sustainability impact data

Impact data coverage indicates what topics a system can handle; traceability capabilities indicate how precisely that data can be linked to products, materials, and processes.

• •Quantitative data - (e.g. numeric values, measurements, calculated indicators)
• •Certificates & formal attestations - (e.g. certificates linked to suppliers, materials, or products)

Life Cycle Assessment  (LCA) handling

Product carbon footprint (PCF) calculations represent a single impact category and do not constitute a full Life Cycle Assessment (LCA), which covers multiple environmental impact categories across the product life cycle

LCA is not handled by the platform;

Risk assessment support

Risk assessment functionality indicates whether a platform supports identifying, prioritising, or visualising potential sustainability or compliance risks. Approaches vary significantly between tools and may rely on user-defined criteria, predefined rules, or system-generated indicators. Risk assessments are intended to support prioritisation and decision-making. They do not in themselves constitute legal compliance or due diligence.

No risk assessment functionality;

Value chain actors involved in data exchange

• •Brand / retailer users - (e.g. internal teams managing products, suppliers, or reporting)
• •Tier 1 suppliers - (e.g. cut-and-sew factories, final assemblers)
• •Tier 2 suppliers - (e.g. mills, dye houses, processors)
• •Tier 3+ suppliers - (e.g. raw material processors, fiber producers)
• •Consumers or external stakeholders - (e.g. read-only access via QR/DPP)
• •Service providers / auditors / certification bodies - (e.g. third-party verification or compliance actors)
• •Logistics or downstream partners - (e.g. distributors, recyclers, end-of-life actors)

Consumer-facing access to product data

• •Consumer-facing product views are provided - (e.g. via QR code, URL, or Digital Product Passport interface)
• •External stakeholder access (read-only) - (e.g. regulators, auditors, partners)
• •Consumer-facing content is configurable by the brand - (e.g. control over which data is displayed)

Digital Product Passport (DPP) development activity

Lingon provides the DPP platform for STELLA, a Vinnova-funded project digitizing the Swedish furniture industry. We enable DPPs for circularity, tracking lifecycles from raw material to recycling. https://www.lingon.io/news-article/vinnova-grant-for-digitalization-stella-project

EU regulatory readiness

Regulatory readiness reflects how a provider monitors and responds to evolving EU sustainability and supply chain regulations. It does not constitute a claim of legal compliance, as regulatory scope and timelines are still evolving.

Close collaboration with academia and policy makers. We hold 4 seats in the Swedish SIS and Cirpass2 for DPP. This ensures our roadmap aligns with EU rules. We run pilots with Interior Cluster Sweden, and EU lighting clusters to ensure industrial conformity.
