Asahi Kasei has developed a system to calculate the carbon footprint of products (CFP) for the synthetic rubber and elastomers products Asadene, Tufdene, Asaprene, Tufprene, Asaflex, Tuftec, and S.O.E. with CFP data provision to customers scheduled to begin in June 2022. CFP visualization is achieved utilizing the DEEP (Data Exploration and Exchange Pipeline) group-wide management infrastructure as a part of the System, which also enables examination of ways to further reduce CFP.
Asahi Kasei’s CFP calculation is based on “Cradle-to-Gate” assessment, which combines upstream emissions of materials and transportation, emissions from in-house manufacturing processes, and energy-related emissions such as electricity used during manufacturing.
The system for CFP data
The Asahi Kasei Group made efforts to strengthen the business platform for sustainable growth from the viewpoint of Green, Digital, and People in its previous medium-term management plan, Cs+ for Tomorrow 2021. In its new medium-term management plan, announced on 11 April 2022, Green Transformation is positioned as one of the key areas for strengthening the management foundation, and Asahi Kasei is advancing reductions of its own GHG emissions as well as contributions to reducing the world’s GHG emissions for the realization of carbon neutrality. Therefore, from the perspective of GHG emissions reduction, Asahi Kasei has sequentially advanced the calculation of CFP for each product starting with the main products, and information provision to certain customers has begun.
As part of the effort to accelerate Green Transformation, Asahi Kasei has begun procuring butadiene derived from plastic waste and biomass as feedstock for solution-polymerized styrene-butadiene rubber (S-SBR).
S-SBR is a type of synthetic rubber used mainly for high-performance fuel-efficient tires (eco-friendly tires). Demand for eco-friendly tires is growing worldwide with stricter environmental regulations and heightened environmental awareness. By enhancing fuel-efficiency performance while maintaining safety performance, S-SBR is recognized as an optimum material for eco-friendly tires. To accelerate efforts for decarbonization to achieve carbon neutrality by 2050, the automotive industry is transitioning to electric vehicles while the tire industry is further improving the fuel-efficiency and wear resistance of tires. Against this background, there is rising demand for greater sustainability of S-SBR as a material for eco-friendly tires, the company says.
The system clarifies the CFP for each synthetic rubber and elastomer product, which allows customers to calculate their own CFP. This furthermore facilitates initiatives to reduce CFP throughout the supply chain as well as in society as a whole. As various regulations related to CFP such as carbon taxes are introduced, CFP data will continue to rise in importance. The system also allows various parameters of the CFP data such as span (yearly or monthly) and scope (average of products or each product individually) to be tailored to meet the diverse needs of customers.
In addition to using the system to visualize CFP, Asahi Kasei will continue to strive toward the carbon neutrality of its synthetic rubber and elastomer products, including the use of sustainable feedstocks and green electricity, and efforts to obtain ISCC certification.
