Offset Your CO2 Emissions by Dollar Amount

US$ 9.90 per tonne | 90.9% goes to projects | 100% U.S. tax-deductible

The average U.S. footprint is 18 tonnes per year (the $178.20 option). Each $25 counteracts 2.53 tonnes of CO2, the amount generated by driving a 30 mpg car for 8,500 miles or 4 medium roundtrip flights (i.e. between Chicago & Denver).
