If the Anthropocene is a rupture in planetary history, what does it mean for international environmental law? When the Earth System crosses irreversible tipping points and begins a forceful, nonlinear transformation into a hostile state which I call the ruptured Anthropocene, the concept of protecting the global environment from humans would lose its meaning. Not only the dichotomy between humans and nature becomes irrelevant, but the environment itself will no longer exist as an object for protection. I argue that, for international environmental law to stay relevant in the ruptured Anthropocene, it needs to shift away from its traditional focus on restoring the planetary past, and instead play an active role in the making of planetary futures. Its new purpose will need to be active planetary stewardship, whereby humans add self-awareness for deliberate self-regulation of the Earth System. Such an attempt at ‘taming’ the so-called Gaia 2.0 will, however, create winners and losers, and the new form of law will have to address fundamental questions of justice on a planetary scale. Building on the concept of earth system law emerging in the earth system governance literature, I draw the contours of international environmental law 2.0 for the ruptured Anthropocene and discuss the challenges of instituting active planetary stewardship.

如果人类世是地球历史上的一次断裂，那么这对国际环境法意味着什么？当地球系统跨越不可逆转的临界点并开始向敌对状态（我称之为破裂的人类世）进行强有力的非线性转变时，保护全球环境免受人类侵害的概念将失去意义。不仅人与自然的二分法变得无关紧要，而且环境本身将不再作为保护对象而存在。我认为，为了让国际环境法在破裂的人类世中保持相关性，它需要摆脱其传统的关注恢复地球过去的重心，转而在创造地球未来方面发挥积极作用。它的新目标需要是积极的行星管理，人类通过这种方式增加了自我意识，以便对地球系统进行有意识的自我调节。然而，这种“驯服”所谓的盖亚 2.0 的尝试将创造赢家和输家，而新的法律形式将不得不在全球范围内解决基本的正义问题。基于地球系统治理文献中出现的地球系统法概念，我为破裂的人类世绘制了国际环境法 2.0 的轮廓，并讨论了建立积极的行星管理制度的挑战。
