Specialized, interdisciplinary or comprehensive approach in technology, policy, and regional cooperation is accelerated around the world to eliminate carbon dioxide emissions by 2050. The Society of Chemical Engineers of Japan has set "Policy Recommendations and Social Implementation for Solving Social Issues" as a priority policy for fiscal year 2020. In this symposium, we will discuss energy and environmental innovation and their social implementation. Why don’t you discuss from various perspectives the chemical engineering challenge of zero emissions through industry-academia-government collaboration and interdisciplinary studies? This symposium is open to the public and is free of charge to all participants. Some of the sessions will be held as an international symposium.
