PlanetAI Space is a technological platform that reveals nature’s hidden value through Earth observation, quantum machine learning, physics, astrophysics and theoretical chemistry. By quantifying the impact of pollutants on ecosystems across the past, present and future, it provides actionable insights to assess, protect and enhance environmental health. It measures environmental assets by applying artificial intelligence (AI) to satellite imagery, assigning value based on their capacity to generate benefits, such as forest carbon sinks and blue carbon sinks. It measures environmental liabilities by detecting pollution in water, air and soil, including turbidity, cyanobacteria, hydrocarbons, methane, PM2.5, PM10, and soil degradation indicators.
