Japan has one of the world’s most advanced manufacturing and construction industries, supported by high technical standards, strong quality control, and increasing focus on carbon reduction and environmental transparency. Environmental Product Declarations (EPDs) are gaining importance in this context, particularly for manufacturers supplying international markets and projects pursuing global sustainability certifications.

In Japan, EPDs are most commonly requested for construction materials used in LEED- and BREEAM-certified developments, as well as for products exported to Europe, North America, and the Middle East. While domestic environmental labelling systems exist, internationally recognised EPDs aligned with ISO 14025 and EN 15804 are increasingly required for global procurement, ESG reporting, and participation in international green building projects.

This has created demand for experienced EPD consultants who can translate Japan’s highly detailed manufacturing data into LCA models that meet international standards and third-party verification requirements.

Role of EPD Consultants in Japan-Based Projects

EPD consultants support manufacturers throughout the complete declaration lifecycle. Typical services include defining system boundaries, collecting and validating production and supply-chain data, developing Life Cycle Assessment (LCA) models, applying relevant Product Category Rules, preparing EPD documentation, and coordinating independent third-party verification.

In Japan, EPD consultancy requires careful alignment with local production practices, advanced process efficiencies, and region-specific electricity grid factors. Consultants must also manage coordination between Japanese-language documentation and international verification bodies, ensuring clarity, consistency, and acceptance across global markets.

EPD consultancy is particularly relevant in Japan for cement and concrete products, steel and aluminium materials, glass, insulation systems, façade components, high-performance building materials, and interior finishes used in both domestic and export-driven construction.

1. ERKE Consultancy

ERKE Consultancy is a sustainability-focused consultancy with extensive expertise in Environmental Product Declarations, life cycle assessment, and product environmental performance. Founded in 2007, ERKE operates through offices in Istanbul, Dubai, and London and delivers EPD services across Europe, the Middle East, and Asia, including Japan-focused projects.

ERKE has completed dozens of EPD certifications for construction products such as cement, concrete, insulation systems, paints, aluminium products, tiles, façade materials, and interior finishes. All EPDs are developed in accordance with ISO 14025, EN 15804, and applicable Product Category Rules, ensuring acceptance by internationally recognised program operators.

A key strength of ERKE is its fully in-house technical team. The consultancy includes LCA specialists and product sustainability experts who manage the entire EPD process internally, from detailed data modelling and scenario development to verification coordination. This structure ensures methodological consistency, efficient delivery timelines, and high-quality documentation.

ERKE’s experience working with manufacturers supplying global markets allows accurate adaptation of LCA assumptions to Japanese production conditions while maintaining strict compliance with international standards. In addition, ERKE’s background in green building certification consultancy enables effective alignment between product-level EPDs and project-level LEED requirements, making ERKE particularly suitable for Japanese manufacturers targeting international projects.
