| Outline of Final Research Achievements |
In this study, we designed a system for the long-term sustainability of international environmental agreements, focusing on the practical applicability of the agreement rules, and clarified the conditions for their establishment by using game theory.
I analyzed and derived the conditions for the establishment of agreements that not only allow many countries to join but also increase the amount of GHG emissions reductions by each country by incorporating technological improvements and diffusion into the rules of the agreements. In addition, these agreements have reduced or different penalties for deviation from the agreement, which is considered to make the agreement rules easier to accept in the real international community.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，発展途上国を含むすべての国々を協定へ加盟させ，それを長期的に維持するための制度や，削減技術の改善および普及を取り入れた協定に関しての研究蓄積を行った．
発展途上国を含むすべての国々が長いスパンで削減目標を掲げ，その達成に向けて努力する必要がある中で，2017年にアメリカが一度離脱を表明するなど安定性に欠けているという問題があることから，本研究は，その解決に向けた１つの指針を示したという意味で社会的な意義を有している．また，現実の国際社会で受け入れられ易い協定ルール（主に懲罰に関するルール）の提案という意味で，今後の国際環境協定の研究の新たな方向性を示すことができた．
