What is a Preliminary or Initial PCF?
A Preliminary (or Initial) Product Carbon Footprint (PCF) is a simplified PCF study that provides an early indication of a product’s carbon footprint. It is designed to:
- Identify major emission hotspots
- Understand the order of magnitude of the Product Carbon Footprint
- Support early decision-making, not public reporting
It is important to keep in mind that the terms “preliminary PCF”, “initial PCF”, or “screening PCF” are not formally defined in ISO standards. They are widely used in industry to describe early-stage assessments carried out before detailed, fully verified PCF studies.
When is a Preliminary PCF useful?
- A production process is still in development or is not yet fully operational
- Primary production data is not yet available
- You want to identify hotspots early, before making major design or investment decisions
- You need an initial indication and not a final product carbon footprint value
This type of study typically sits at the early, less formalized stage of carbon footprinting.
What can (and can’t) a Preliminary PCF be used for?
What it can be used for:
- Identifying key emission drivers (materials, energy use, process steps)
- Estimating a PCF range or an indicative PCF
- Supporting internal strategy, R&D, and design decisions
- Preparing a data collection roadmap for future detailed assessments
- Engaging early with suppliers on data and reduction opportunities
What it cannot be used for:
- Public comparative claims
- Marketing or product labeling
- Externally verified PCF disclosures
The results are indicative, not definitive.
Typical characteristics of a Preliminary PCF
- Use of secondary or generic data (e.g., industry averages, databases such as ecoinvent)
- Limited system boundaries (often cradle-to-gate)
- Simplified assumptions
- Lower data quality compared to a final PCF
- Shorter execution time
- A clear statement that the results are not suitable for public comparison
At Prelude Analytics, we offer Preliminary PCF analyses that are designed specifically for early-stage products and processes.
