Pick the Right PCR Every Time
Choose the wrong Product Category Rule and your EPD can skid off the track before it even starts. The right one unlocks credible carbon numbers, smoother third-party reviews, and faster market access. Here’s how technical teams zero in on the perfect rulebook—without drowning in acronyms.
PCRs: Your EPD Rulebook
A PCR is the official playbook that tells an LCA practitioner what data to collect, which impact factors to use, and how to slice the life-cycle pie. Ignore it and your declaration ends up as off-brand as Monopoly played with Uno cards.
Start With Functional Equivalence
First question: what service does the product deliver over which reference unit? For cladding panels, a square meter installed counts; for sealants, maybe one linear meter at specified thickness. Match that service unit to the PCR title before anything else (ISO 14025, 2024).
Scan the Program-Operator Libraries
Program operators publish searchable PCR lists. Hit IBU’s “Geltende PCR” page, ECO Platform’s master table, and UL’s online database. In July 2025, 71 percent of all construction PCRs sat in just three libraries (ECO Platform, 2025). Five minutes here can save five weeks of wild-goose emails.
Check Revision Calendars and Draft Updates
A PCR older than five years can trigger extra verification hoops. EN 15804-A2 PCRs published pre-2020 face sunset dates as early as December 2025 in the EU (IBU, 2025). If a draft update is already under public review, align with the new methods now to dodge redo costs later.
Weigh Regional vs Global Harmonization
A US asphalt shingle maker eyeing bids in Germany might find two PCRs: one under ISO 21930 and one under EN 15804. Compare declared modules, characterization factors, and allocation rules. Harmonizing to the stricter framework often costs pennies more in modelling time but returns multi-market acceptance.
Fill Gaps With Interim Guidance
If no PCR covers your niche—think 3-D printed cementitious forms—program operators allow interim rulesets. Most follow EN 15804 scaffolding plus product-specific annexes. Draft these annexes with the verifier from day one to avoid enviromental data loops.
When No PCR Fits, Lead the Draft
Around 12 percent of construction EPDs in 2024 relied on PCRs initiated by a single company (ECO Platform, 2025). Driving a new rule adds three to six months, but it also sets the benchmark competitors must follow.
Right Rule, Faster Path to Market
Selecting the correct PCR is half diligence, half detective work. Nail it early and the rest of the EPD process runs like a well-oiled conveyor, ready to ship credible numbers to specifiers before the next bid window closes.
Frequently Asked Questions
How long does it typically take to draft a new PCR from scratch?
Most program operators quote six to nine months, but timelines can stretch if stakeholder comments pile up. Engage industry peers early and provide clear test data to streamline the public-review phase.
Can one EPD reference two different PCRs to cover multiple markets?
Yes, if the PCRs share a common parent standard (like EN 15804). The declaration must label how each requirement was met and undergo dual verification, adding modest but manageable cost.
What happens if my chosen PCR expires mid-project?
Program operators usually grant a grace period—often 6–12 months—for EPDs already in progress. Confirm this window in writing with the operator before committing resources.
Are interim PCRs accepted for LEED v5 credits?
LEED v5 draft language (USGBC, 2024) accepts interim PCRs only when no published rule exists and the interim follows ISO 21930 plus third-party review. Double-check the final text once LEED v5 is formally released.
