The Planetary Health Check is a yearly report on the state of our planet. It presents the most up-to-date assessments of the Planetary Boundaries, gives thorough introductions into cutting-edge science, and spotlights especially relevant aspects of our planet's health. This 2026 edition places a special focus on carbon sinks and novel entities.

The Planetary Boundaries Science (PBScience) project was launched in 2023 to address critical gaps in our understanding and monitoring of the Earth system. Utilising advanced simulation modeling, incorporating the latest available measurement datasets and synthesizing new insights from Earth system science literature, PBScience provides annual Planetary Health Checks based on the Planetary Boundaries framework. PBScience strives to elevate global awareness and drive action towards maintaining planetary stability.

The Planetary Boundaries

The Planetary Boundaries define rules that help us keep our planet safe, healthy, and protect life on Earth.

Human activities have pushed Earth beyond its Safe Operating Space. The planet's natural resilience is weakening: Global warming is accelerating, ecosystems are showing clear signs of degradation, and early warning signs of tipping points are emerging in key systems. We have entered the Anthropocene — an era where human activity dominates the Earth system.

To safeguard the Earth's resilience and stability, we must bring the planet back into its Planetary Boundaries. These boundaries are scientifically defined guardrails that ensure the Earth's health. Stay within them, and the Earth stays our dependable home — breach them, and we risk irreversible damage to our very own life support system. Today, seven out of nine boundaries have been transgressed.
