解决全球性环境问题既需要全球的合作,又要重视发展中国家的作用。在保护和改善环境的协作中各国达成了共同但有区别的责任。共同但有区别的责任在斯德哥尔摩会议上萌芽,蒙特利尔公约使其初具雏形,最后确立于里约会议,成为国际环境法一项重要的原则,为国际环境法的发展注入新的活力。 To solve the global environmental problems, we need both global cooperation and the role of developing countries. Countries have common but differentiated responsibilities in their cooperation to protect and improve the environment. Common but differentiated responsibilities germinate at the Stockholm Conference. The Montreal Convention made it a prototype. It was finally established at the Rio Conference and became an important principle of international environmental law, infusing new vitality into the development of international environmental law.
