Nature’s capacity to store carbon makes it one of the most effective—yet underutilized—tools in the fight against climate change. Through photosynthesis, soils, forests, wetlands, and grasslands absorb atmospheric CO₂ and store it in biomass and subsurface organic matter, making them enormous, living carbon sinks. Soils store three times as much carbon as the atmosphere, and forests store over a quarter of the world’s carbon.
