Status: pending real data
How to Get an EPD (in the Getting an EPD section) gives the general two-to-six-month range for the overall process. This page needs stage-by-stage timeline data — how long data collection, modeling, drafting, and verification each typically take — confirmed with consultants and program operators before it can show more than that general range.
What this page will cover
- Stage-by-stage timeline breakdown (data collection, LCA modeling, drafting, verification, publication)
- How timeline varies by product-specific vs. industry-average EPDs
- How timeline varies by program operator
- Common causes of delay
See How EPDs Work for the process itself, and How Long Does It Take for the general range while this page’s detailed breakdown is pending.
