Domestic and international trends and future prospects regarding CFP calculation for batteries

My commentary, "Domestic and international trends and future prospects for CFP calculations for batteries," was published in Volume 21, Issue 2 (April 2025 issue) of the Journal of the Life Cycle Assessment Society of Japan.

This commentary points out that while the carbon footprint (CFP) of a product has been attracting attention as a means of quantitatively indicating its impact on climate change, the lack of a unified calculation method has made it difficult to use it in legal regulations. In recent years, an information infrastructure for CFP calculation has been established in Europe, and CFP is being introduced into EU regulations.

In particular, the following three systems were explained:

  1. CBAM(Border Carbon Adjustment Measures): Requires CFP reporting and carbon pricing for some imported products, such as steel and aluminum.
  2. European battery regulations: Requirement for battery products to submit CFP and emission information throughout their life cycle, utilization of primary data, and strengthening of traceability.
  3. Ecodesign Regulation (ESPR): Makes it mandatory for products distributed within the EU to disclose information in a digital product passport, including durability, recyclability, CFP, etc.

He also touched on the international harmonization of CFP calculations in the automotive industry and global system trends, and proposed future directions for institutionalization and practical responses.

This was written in January 2025, and since then, omnibus bills have been proposed in Europe, and there are moves to simplify the system. However, it is important to note that the direction we are heading in the long term has not changed.
