EN 1337-5:2026 Enforces Carbon Footprint Disclosure for Bridge Bearings

Brussels, 16 May 2026 — The European Union has formally implemented EN 1337-5:2026, introducing mandatory lifecycle carbon footprint disclosure for bridge bearings under the CE marking framework. Effective immediately upon publication in the Official Journal of the European Union (OJEU), this standard reshapes compliance requirements for structural bearing manufacturers and exporters—particularly those based in China and other third countries supplying EU infrastructure projects.

Event Overview

On 16 May 2026, the European Committee for Standardization (CEN) published EN 1337-5:2026 Structural Bearings — Part 5: Environmental Declaration and Verification Requirements for Seismic Isolation Bearings in the Official Journal of the European Union. The standard enters into force on the date of publication and applies without transitional period. It mandates that all bridge bearings placed on the EU market must be accompanied by a third-party-verified Environmental Product Declaration (EPD), covering cradle-to-grave stages: raw material extraction, manufacturing, transport, and maintenance over the product’s declared service life.

Industries Affected

Direct Exporters (Bridge Bearing Manufacturers & Distributors)
Export-oriented manufacturers—especially those in China, South Korea, and Turkey—now face revised CE conformity assessment pathways. Type examination under EN 1337-1 to -4 alone is no longer sufficient; submission of an EPD verified against EN 15804+A2 or ISO 21930 is now a statutory prerequisite for CE documentation. This extends average certification lead time by 8–12 weeks and increases associated verification costs by an estimated 15–25% per product family.

Raw Material Suppliers
Suppliers of elastomeric compounds, stainless steel components, and high-strength alloys must now provide upstream environmental data—including primary energy use, embodied carbon, and traceable sourcing information—to enable EPD compilation. Absence of verifiable data at Tier 2 or Tier 3 levels may trigger supply chain bottlenecks, especially where recycled content claims or low-carbon steel procurement are required for EPD optimization.

Manufacturing Facilities (OEMs & Contract Producers)
Production sites must document energy sources, process emissions, waste streams, and logistics routing with granularity sufficient for LCA modeling. Facilities lacking ISO 50001 or ISO 14064-1 alignment may encounter delays during EPD verification audits. Notably, the standard references EN 15978 for system boundaries, meaning scope 1 and 2 emissions are mandatory—and scope 3 (upstream transport, end-of-life) is strongly encouraged.

Supply Chain Service Providers (Testing Labs, Certification Bodies, LCA Consultants)
Certification bodies accredited under EN ISO/IEC 17065 must now demonstrate competence in reviewing EPDs per EN 15804+A2. Independent LCA practitioners and software providers (e.g., GaBi, SimaPro users) report rising demand for EU-compliant database integration—particularly for regionalized electricity mixes and transport emission factors. Lead times for EPD verification services have tightened, with priority access increasingly reserved for clients with pre-submitted inventory data.

Key Focus Areas and Recommended Actions

Verify EPD Scope Alignment with EN 1337-5:2026 Annex A

Manufacturers must confirm their EPD covers all stages specified in Annex A—including ‘in-service maintenance’ (e.g., lubrication intervals, replacement parts). Generic construction-sector EPDs are insufficient; declarations must be product-specific and linked to the exact bearing type, load capacity, and seismic performance class.

Engage Accredited Verifiers Early in Design Phase

Given the 8–12 week verification window, initiating EPD development during prototype testing—not post-certification—reduces time-to-market risk. Select verifiers listed on the European Organisation for Technical Approvals (EOTA) database with documented experience in structural products.

Audit and Document Tier 1–3 Supply Chain Data

EPD validation requires auditable data down to component level (e.g., rubber compound formulation, steel mill origin). Firms should map supplier tiers and request Environmental Product Declarations or verified carbon intensity values—not just supplier sustainability statements.

Editorial Perspective / Industry Observation

Observably, EN 1337-5:2026 signals a structural shift from ‘compliance as documentation’ toward ‘compliance as data stewardship’. Unlike earlier eco-design directives, this standard embeds environmental accountability directly into harmonised technical specifications—not just CE marking procedures. Analysis shows it sets a precedent likely to cascade into other EN 1337 parts (e.g., fixed and sliding bearings) within 24 months. From an industry perspective, the requirement is less about carbon reduction per se—and more about transparency infrastructure: firms with mature digital product passports, ERP-integrated LCA modules, and supplier data-sharing protocols are already reporting smoother transitions.

Conclusion

This regulation does not merely add a new box to check—it redefines what constitutes technical equivalence in structural engineering markets. For global suppliers, meeting EN 1337-5:2026 is not only a regulatory necessity but also an emerging differentiator in public tenders where environmental criteria carry weighted scoring. The broader implication lies in accelerated convergence between building-level EPD mandates (e.g., Level(s), EU Taxonomy) and component-level declarations—a trend that consolidates life-cycle thinking across the built environment value chain.
