On April 30, 2024, "The Methodology for the Calculation and Verification of the Carbon Footprint of Electric Vehicle Batteries" *1 (hereinafter tentatively referred to as "CFP Detailed Regulations (Draft)") was published, which presents a methodology for calculating and verifying the carbon footprint of on-board batteries. In response to this, on May 23, 2024, we published a column on our website explaining our interpretation of the CFP Detailed Regulations (Draft) *1 of the EU Battery Regulation, in which we explained the following points:

→ Interpretation of the CFP detailed rules of the EU Battery Regulation ①

CFP Functional Unit
Parts items stipulated as Mandatory Company Specific process
Data sharing across the supply chain

Next, on July 5, 2024, we published our second column on our interpretation of the CFP regulations, explaining the calculation requirements in practical terms.

→ Interpretation of the CFP detailed rules of the EU Battery Regulation ② ~Complete guide to the CFP detailed rules for complying with the EU Battery Regulation: Cutoff rules and DQR value Settings~

Items subject to calculation or cutoff
How to select the data set (Emission factor)
How to Settings DQR

In this third column, I would like to explain "modeling," one of the most difficult calculation requirements to interpret, and the most difficult of these, the "Circulation Footprint Formula (CFF)."

Below is a summary of the column, which you can download.

1. About modeling

This paper explains the concept of "modeling" in CFP calculation. It then explains the calculation methods introduced in the CFP detailed regulations, from the allocation of Energy consumption when producing multiple product numbers on the same line to the method of reflecting direct consumption of renewable energy electricity in CFP. It also introduces situations where it is necessary to design a calculation formula for "modeling" in actual calculation, even though this is not stated in the CFP detailed regulations.

2. Circulation Footprint Formula for Disposal and Recycling Processes

We will explain CFF in the disposal and recycling process. We will explain the structure of the CFF calculation formula after developing our interpretation of unique concepts such as "credit", "market allocation", and "return and recovery".

3. Circulation Footprint Formula for the Use of Recycled Materials

This article explains CFF when using recycled materials. Unlike the calculation formula for CFF in the disposal and recycling process, this calculation formula reflects credits and the quality of recycled materials in a complex manner. Therefore, after developing two ways of interpreting it, we will explain the Issue and pitfalls in carrying out actual calculation work.
