- Three domains carry red alerts—biosphere integrity, biogeochemical flows, and chemical and plastic pollution—while freshwater use is rated orange.
- Only the stratospheric ozone layer and atmospheric aerosols are still classified in the safe zone.
- Land‑use change is among the exceeded limits and is advancing rapidly in parts of Latin America, including Mexico, Bolivia, and the Peruvian Amazon.
- The report highlights outsized responsibility by major emitters such as the United States, China, and India, and the coverage criticizes stalled policy action and weak follow‑through on recent COP commitments.
