The Anthropocene depicts Earth's most recent geologic time period as human-influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric, and other earth system processes are now being altered by humans. As a diagnostic tool for measuring the world's ecosystem balance, the group has developed a planetary boundary model with a focus on nine processes that regulate the stability and resilience of the Earth system. The framework proposes precautionary quantitative planetary boundaries within which humanity can continue to develop and thrive, also referred to as a 'safe operating space'. The overshoot of planetary boundaries necessitates a major revision of current governance regimes which must oversee a green transition in industrial societies. From a motivational point of view, the task of green governance is therefore to show how green growth expands opportunities for value creation and social improvement, and could transform the trilemma into a triple fortuity.
