Proactively disclosing climate change-related information

Examples of our activities/efforts

● Developing synthetic rubber using biomass

As part of our efforts to achieve carbon neutrality, we are participating in an industry-academia collaboration developing a technology to produce butadiene and isoprene, the core raw materials used in synthetic rubber, from biomass rather than petroleum.
