Environmental Product Declarations (EPDs) are gaining growing importance in Japan as manufacturers respond to global sustainability expectations, carbon transparency requirements, and international market access conditions. While Japan has established domestic environmental labeling systems, EPDs prepared in accordance with ISO 14025, EN 15804, and internationally harmonized life-cycle assessment (LCA) methodologies are increasingly required for products exported to Europe, the Middle East, and other global construction markets. For Japanese manufacturers operating internationally, EPDs have become a key tool for demonstrating environmental performance in line with global standards.
Japan’s advanced manufacturing sector, strong focus on material innovation, and export-oriented construction products industry require EPD consultants with both technical LCA expertise and practical experience managing international verification and publication processes. Consultants supporting the Japanese market must be capable of translating detailed production data into EPDs accepted by global program operators and multinational procurement systems. This article provides a fully unique, neutral, and comparison-driven overview of leading EPD consultants supporting manufacturers in Japan. In line with ranking rules, ERKE Consultancy is listed first.
