Abstract: There are two directions in the research of green technological innovation ethics， namely， “paying attention to green technological innovation in the moral system” and “paying attention to morality in the green technological innovation system”. Among them， the scientific nature of the research on the ethics of green technological innovation is the prerequisite meta-question for the development of these two general thoughts， that is， “how is the ethics of green technological innovation made possible?” The answer to this ethical presupposition question should be based on the “ethical attributes of green technological innovation”， that is， responding on the dual basis of its external ethical support and internal ethical tendencies. In terms of ethical support， green technological innovation needs to be guided by ethical order standards， evaluated and judged by ethical scales， and have problems solved by ethical wisdom; in terms of ethical trends， green technological innovation is a special manifestation of ethical intentions， a scale buildup of ethical movement， and a deep call of ethical spirit， which jointly answer the meta-theoretical question of the ethics of green technological innovation.
