ADDC Extends EPD Mandate to All Silicone Sealants in UAE

On May 2, 2026, the Abu Dhabi Distribution Company (ADDC) expanded its environmental product declaration (EPD) requirement to cover the full range of silicone sealants — including alkoxy-cure, oxime-cure, and addition-cure types — for all ADDC-led smart city and airport expansion projects. This development signals heightened sustainability compliance expectations for construction materials suppliers operating in the UAE’s green infrastructure sector.

Event Overview

On May 2, 2026, ADDC published Sustainable Procurement Supplementary Terms V2.1, mandating that all silicone sealants supplied for ADDC-managed infrastructure projects must carry a verified EPD. The EPD must demonstrate a carbon intensity of ≤0.8 kgCO₂/kg and be certified by either UL SPOT or EPD International. The scope now explicitly includes alkoxy-cure, oxime-cure, and addition-cure silicone sealants — extending beyond prior requirements limited to general building sealants.

Industries Affected

Direct Exporters & Trading Firms

Exporters supplying silicone sealants into the UAE — particularly those targeting ADDC-contracted projects — are directly affected because EPD certification is now a contractual prerequisite. Non-compliant products risk rejection during tender evaluation or delivery inspection.

Raw Material Suppliers

Suppliers of silicone polymers, crosslinkers, fillers, and catalysts may face upstream data requests from downstream sealant manufacturers seeking to compile verified life cycle inventory (LCI) data for EPD registration. Traceability of embodied carbon in raw inputs becomes operationally relevant.

Sealant Formulators & Manufacturers

Manufacturers producing silicone sealants for UAE infrastructure must now ensure each product variant (by cure chemistry and formulation) has an EPD meeting the ≤0.8 kgCO₂/kg threshold and recognized certification. This implies potential reformulation, LCA study commissioning, and documentation alignment with UL SPOT or EPD International protocols.

Distributors & Project Specifiers

Distributors engaged in ADDC-tendered projects must verify EPD status before quoting or delivering. Specifiers (e.g., consultants, contractors’ technical teams) will increasingly require EPD documentation at submittal stage — shifting technical evaluation criteria beyond performance and pricing alone.

What Relevant Enterprises or Practitioners Should Monitor and Do

Track official implementation timelines and scope clarifications

While the policy took effect on May 2, 2026, ADDC has not yet published transitional provisions or grandfathering clauses for existing contracts. Enterprises should monitor ADDC procurement portals and tender addenda for operational guidance on enforcement phasing.

Verify EPD eligibility for specific silicone sealant chemistries

Not all silicone sealant types have publicly available EPDs — especially niche or newly formulated variants. Companies should confirm whether their exact SKUs meet both the carbon intensity threshold and certification body requirements, rather than relying on generic category-level declarations.

Distinguish between policy signal and procurement reality

This mandate applies only to ADDC-led projects — not all UAE federal or emirate-level infrastructure. Its influence on broader Gulf markets (e.g., Saudi NEOM, Qatar’s Lusail) remains unconfirmed. Enterprises should avoid overgeneralizing this as a regional standard until further regulatory alignment emerges.

Prepare documentation and supplier coordination in advance

Compiling an EPD typically requires 3–6 months, including LCA modeling, third-party verification, and registry publication. Manufacturers and exporters should initiate EPD development workflows now — particularly for high-volume SKUs — and align raw material suppliers on data sharing agreements.

Editorial Perspective / Industry Observation

Observably, this update reflects a maturing phase in Middle Eastern green procurement: from voluntary sustainability reporting toward enforceable, chemistry-specific carbon thresholds. Analysis shows it is less a standalone regulation and more a calibrated extension of ADDC’s existing sustainable procurement framework — indicating institutional capacity to implement granular environmental criteria. From an industry perspective, it functions primarily as a forward-looking signal: while immediate project impact is confined to ADDC’s portfolio, it sets a precedent for technical rigor that other Gulf utilities and infrastructure authorities may adopt incrementally. Current relevance lies not in universal applicability, but in its role as an early indicator of tightening carbon accountability across construction chemical supply chains in energy-intensive infrastructure development.

Conclusion: This policy shift underscores a structural move toward embedded carbon accountability in Gulf construction material specifications. It is best understood not as an isolated compliance hurdle, but as part of a broader trajectory where environmental transparency — verified, chemistry-specific, and quantitatively bounded — becomes a baseline condition for market access in major public infrastructure programs.
