Asahi Kasei Gets Independent Verification for Acrylonitrile Carbon Footprint at South Korea Plant

Asahi Kasei's South Korean subsidiary Tongsuh Petrochemical received Reasonable Assurance verification from Socotec Certification Japan for the product carbon footprint of acrylonitrile produced at its Ulsan plant. The audit covered fiscal 2025 emissions from raw material procurement through production. This is a higher bar than Limited Assurance, so buyers can treat the reported carbon data as independently checked. The company has been working on lower-carbon acrylonitrile for a few years. It got ISCC PLUS certification in 2021 and has sold acrylonitrile made from biomass-based propylene via mass balance since 2022. Asahi Kasei says it will keep cutting emissions through catalyst and process improvements and more bio-based feedstocks. Verified product carbon footprint data matters for downstream industries that use acrylonitrile in ABS resins, acrylic fibers, and carbon fiber precursor material. Those customers need reliable numbers for their own scope 3 reporting and low-carbon procurement decisions.

Good to see AN producers moving beyond self-reported carbon numbers. The Socotec reasonable assurance piece matters because buyers need verified data for their own scope 3. Would be useful to know the actual PCF number though, the release doesn't state it.

The missing PCF value is the weak spot. Verification without a number is just process. Also worth watching whether biomass mass balance gets audited the same way as fossil carbon accounting. Different rules can shift the result.

Acrylonitrile is an energy intensive chemical, so the interesting part is what the emissions profile actually looks like. Ulsan uses naphtha cracking? Not clear from release. Third party verification is good but the production route and grid mix decide how useful this is.

Agreed. The article focuses on feedstock and verification, not the energy input. If the plant runs on fossil power, the PCF is still high. Biomass propylene helps only part of the footprint.

For industrial buyers, verified PCF data is becoming a purchasing requirement, especially in autos and electronics. This puts Asahi Kasei ahead on documentation. The next step is showing actual reduction, not just accounting changes.
