The progression of global warming is a serious issue threatening the sustainability of humankind and the existence of the social economy. As a result, we consider environmental issues on a worldwide scale. Regarding the Paris Agreement drafted at COP 21 and the draft version of “Japan’s Promise” submitted to the United Nations, the Japanese government made a Cabinet decision called the Plan for Global Warming Countermeasures on May 13, 2016. This decision is to comprehensively and systematically promote global warming countermeasures
