How sure are the numbers in an EPD, and how should a PCR deal with it? This ACLCA technical guidance, Uncertainty: Management in Product Category Rule (PCR) Development and Reporting in Environmental Product Declarations (EPDs), gives PCR committees and LCA practitioners a practical framework for characterizing and communicating uncertainty, so EPD results hold up when buyers, specifiers and regulators rely on them.
What's inside:
- Data-source hierarchies and ranges for background and foreground data
- Sensitivity and data-quality assessment methods
- How to report uncertainty in an EPD
- Worked examples using Global Warming Potential, with a framework that extends to other indicators
