AA is widely used as a raw material for paints and adhesives, and serves as a key ingredient in SAP, which is used in disposable diapers. As a leading global supplier of AA and SAP, Nippon Shokubai Group has been working to obtain ISCC PLUS certification for products manufactured in Belgium, Japan, and Indonesia since 2021. Following the recent certification in the United States, Nippon Shokubai Group has established a four-region global supply system for ISCC PLUS-certified AA and SAP using biomass-derived raw materials allocated via the mass balance method (*3). This enables the global supply of AA and SAP with a carbon footprint considered net zero.

Through promoting the use of ISCC PLUS-certified AA and SAP, Nippon Shokubai Group aims to contribute to reducing environmental impact across the supply chain and to advancing a circular economy. Toward carbon neutrality by 2050, Nippon Shokubai Group will continue to implement the "transformation" outlined in its long-term vision and mid-term management plan to enhance customer value.

(*1) ISCC (International Sustainability and Carbon Certification): It is a third-party certification program developed by International Sustainability and Carbon Certification (ISCC) system GmbH based in Germany to manage and guarantee sustainable raw materials and products such as biomass and recycled materials in the supply chain.

(*2) Carbon footprint considered net zero: ISCC PLUS-certified products incorporate the biogenic CO2 removal associated with biomass growth into their carbon footprint calculations. The carbon footprints of these products are considered effectively net zero through the proportionally offset based on the share of biomass-derived feedstock allocated using the mass balance method.

(*3) The mass balance method: When biomass-derived and petroleum-derived raw materials are used together in production, the proportion of biomass input can be allocated to specific end products. This method is officially recognized under the ISCC PLUS certification system.
