Concerning the access to bio-based and DAC-CCU feedstocks, the chemical industry in Japan can start with the import of blue or green methanol or green ethanol to establish a supply chain, but it should also make a long-term investment in establishing a secure and stable supply. In addition, implementing post-incineration CCS or CCU throughout Japan is essential for achieving scope 3 net zero for the chemical industry and its value chain. This can be achieved through an extended producer responsibility program.
