Researchers have found that California's forest carbon buffer pool, designed to ensure the durability of the state's multi-billion-dollar carbon offset program, is severely undercapitalized. The results show that, within the offset program's first 10 years, estimated carbon losses from wildfires have depleted at least 95% of the contributions set aside to protect against all fire risks over 100 years. This means that the buffer pool is unable to guarantee that credited forest carbon remains out of the atmosphere for at least 100 years. The results, published in Frontiers in Forests and Global Change, illustrate that the program, one of the world's largest, is likely not meeting its set requirements.
