    • Charm removes CO₂ by collecting excess bio-mass, turning it into oil, and injecting the oil back into the ground. Alternatively, bacteria would decompose the biomass and it would re-enter the atmosphere as CO₂.

      Charm’s offsets have geologic permanence, which means the CO₂ you inject in the ground will be there for thousands of years. This is unlike traditional offsets like trees, which can burn down within a few decades.

      Charm’s secret sauce is its ability to extract other hydrocarbon products from pyrolysis process to make the overall process more affordable over time.

    • Once you’ve selected your desired monthly budget, you’ll be able to see how many tons of CO₂e your subscription will remove, calculated in the checkout. For each month of your subscription, we remove the tonnage associated with your budget. As our price per ton comes down over time, your monthly subscription becomes worth more CO₂e!
