The Planetary Health Check (PHC) report provides an assessment of the state of our planet. It is based on the Planetary Boundaries (PBs) – the nine processes that are known to regulate the stability, resilience (ability to absorb disruptions) and life-support functions of our planet. Each of these processes, such as Climate Change or Ocean Acidification, is currently quantified by one or two control variables. The 2025 PHC report concludes that seven out of nine Planetary Boundaries have been breached, with all of those seven showing trends of increasing pressure – suggesting further deterioration and destabilization of planetary health in the near future.
The Planetary Boundaries Science (PBScience) project was launched in 2023 to address critical gaps in our understanding and monitoring of the Earth system. Utilizing 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. Collaborating closely with the Planetary Guardians and other partners, PBScience strives to elevate global awareness and drive action towards maintaining planetary stability.
