For every $1 contributed, Carbon Checkout offsets 245 pounds of CO2-equivalent emissions. Our offsets are currently trading at $4.08 per 1,000 pounds of emission reductions, the lowest trading price of any retail renewable energy carbon offset provider. Compare this with The Nature Conservancy who offsets 147 pounds of CO2-equivalent emissions per $1 collected, and with a minimum purchase of $15 for one metric ton. We do more good, with every dollar contributed.
