The final documents, ERW Edition 2025 Version 1, the Transition Plan, and the Public Consultation Outcome, are now available in Puro’s document library. The updated methodology reflects extensive collaboration across the ERW community, with many public consultation comments leading to refinements that enhance scientific integrity, practicality, and efficiency. Puro has launched a structured transition plan: certified facilities may continue using prior until their crediting period ends or adopt the 2025 edition earlier; facilities registered before Dec. 15, 2025, have until Feb. 18, 2026, to submit audit materials or may request certification under the new edition; and facilities registered on or after Dec. 15, 2025 must follow the new 2025 version. Puro will provide ongoing support to ensure a smooth transition for all stakeholders, it said.
