The Circular Footprint Formula (CFF) is one of the most complex parts of calculating battery carbon footprints under the EU Battery Regulation. This series breaks it down into three parts: what the CFF is, how to implement it correctly, and how to work with suppliers to move beyond default parameters.
What You’ll Learn
This three-part series covers everything you need to build a robust CFF calculation:
Part 1: The CFF Explained
What it is, where it comes from, and why it matters.
You’ll understand the six terms of the CFF, how material flows work at end-of-life, and why the CFF represents a significant portion of the total carbon footprint. This is the foundation for everything else.
Part 2: Implementation Pitfalls
The architecture decisions and common mistakes that make or break a CFF calculation.
Moving from the regulation’s formula to a working calculation engine involves many hidden decisions. This part covers the pitfalls that trip up even careful implementations and the data architecture patterns that keep calculations auditable.
Part 3: Working with Suppliers
Moving beyond defaults to company-specific data.
Default CFF parameters are conservative. This part covers how to work with suppliers to collect actual recycled content data, when it’s worth the effort, and how to structure the data collection process.
Who This Is For
- Compliance managers who need to understand what their technical teams are building
- Analytics engineers implementing carbon footprint calculations
- Sustainability managers evaluating battery suppliers’ data quality
Prerequisites
Basic familiarity with the EU Battery Regulation and carbon footprint concepts. No deep technical background required for Part 1; Parts 2 and 3 assume some data architecture knowledge.
