& Ecosystem Projects
The authoritative sources behind tap2.cloud's compliance logic — plus the open-source ecosystem projects that DPP infrastructure is being built on.
EU Regulatory Framework
The eight primary regulations and directives governing Digital Product Passports and sustainable product design
Ecodesign for Sustainable Products Regulation (ESPR)
The foundational regulation establishing Digital Product Passport requirements for most product categories. Replaces the Ecodesign Directive (2009/125/EC). Delegated acts will specify per-product requirements, starting with textiles and electronics.
Battery Regulation
Mandatory Battery Passport for EV batteries, industrial batteries ≥2 kWh, and LMT batteries from February 2027. Specifies 70+ mandatory data points including carbon footprint, recycled content, and state-of-health. The most detailed DPP specification currently in EU law.
REACH — Substances of Very High Concern
Registration, Evaluation, Authorisation and Restriction of Chemicals. SVHC declarations above 0.1% weight/weight are mandatory DPP fields for all product categories. The ECHA SCIP database is the EU submission portal for article-level substance notifications.
RoHS — Restriction of Hazardous Substances
Restricts use of 10 hazardous substances in electrical and electronic equipment. RoHS compliance declarations are required DPP fields for electronics, e-textiles, and connected products. Annex IV substances include lead, mercury, cadmium, and certain phthalates.
Digital Services Act
Governs digital traceability for online marketplaces selling physical products into the EU. Platforms must verify seller identity and product compliance — creating a demand-side pull for DPP availability on marketplace listings.
Waste Framework Directive (amended 2018)
Extended Producer Responsibility (EPR) framework requiring producers to fund and organise take-back and recycling. EPR scheme registration and reporting data links to DPP lifecycle tracking — enabling automated EPR reporting for textiles, tyres, and electronics.
General Product Safety Regulation
Replaces the General Product Safety Directive from December 2024. Requires economic operators to maintain traceability data for all consumer products — directly overlapping with ESPR DPP requirements for non-regulated categories.
EU Deforestation Regulation
Mandatory due diligence for cattle, cocoa, coffee, palm oil, soya, wood, rubber, and derived products. Geolocation data proving commodity origin does not come from deforested or degraded land — a data requirement structurally identical to DPP origin declarations.
Open Ecosystem Projects
The standards bodies, open-source projects, and EU initiatives that DPP infrastructure is being built on
Eclipse Dataspace Connector (EDC)
Open-source dataspace connector enabling secure, sovereign data exchange between supply chain actors. The reference implementation for Catena-X and CIRPASS interoperability. tap2.cloud's Cross-Actor Messaging module is built on EDC.
github.com/eclipse-edc →CIRPASS-2 (EU Pilot)
EU-funded pilot project defining the technical architecture, data models, and interoperability standards for the European DPP ecosystem. tap2.cloud aligns its schema definitions with CIRPASS-2 outputs.
cirpassproject.eu →Asset Administration Shell (AAS)
The Industry 4.0 standard for digital twins and product data exchange, maintained by the Industrial Digital Twin Association (IDTA). AAS submodels provide the technical structure for machine-readable DPP data exchange.
industrialdigitaltwin.org →GS1 Digital Link
The GS1 standard encoding product identifiers (GTIN, SGTIN) into URLs that resolve to structured data. DPP QR codes built on GS1 Digital Link enable any scanning device to resolve a persistent DPP URI — a requirement under the ESPR carrier standard.
