The Planetary Health Check (PHC) report assesses the state of our planet through the Planetary Boundaries, nine systems that keep Earth stable and able to support life. Like a blood test for the human body, the PHC tracks 13 scientific indicators to measure stability, resilience, and overall planetary health. The 2025 results show that most of these systems are under growing pressure, signalling further decline and rising risks for the future.

We’ve drawn the line. This isn’t just a campaign. It is a powerful statement that humanity is on the verge of crossing a critical threshold. The red line of the Planetary Boundaries signals the danger of leaving the Safe Operating Space, but it also shows that we can still move back toward the green line of balance and resilience. Draw the Line confronts the urgent reality of seven breached boundaries while spotlighting solutionists, people already working to repair and regenerate. The message is clear: we are at the line, and it is time to act. Now it is up to all of us to draw the line for the planet’s health.

All over the world, everyday guardians are taking action, restoring Earth’s balance and regenerating ecosystems. Their work shows that we can step back from the red line and move toward the green line of resilience and renewal. Below, we highlight some of these solutionists whose efforts light the path forward.

The Three Basins, One Lifeline report from the Planetary Guardians demonstrates that safeguarding the Amazon, Congo, and South-East Asian rainforest basins is both an environmental priority and a macroeconomic imperative. Holding 80% of the world’s remaining rainforests and two-thirds of its biodiversity, these basins regulate global weather, secure freshwater for food production, and store vast amounts of carbon. Yet with only 36% of their forests left intact, urgent action is needed.

The report makes it clear: the resilience of the Three Basins is more than just an environmental priority; it is a macroeconomic imperative, and crucial for humanity to thrive.  Effective investment in avoided deforestation provides over 40% of low-cost abatement potential at just US$20–50 per tCO₂ -seven to ten times cheaper than reforestation. Research shows that nature-based solutions, primarily forest conservation and restoration, can deliver 37% of the cost-effective climate mitigation needed by 2030. To unlock this potential, the report calls on global Finance Ministers, international development banks, and global investors to treat the protection of the Three Basins as a critical investment.
