Reforestation

Planting trees is another way to take CO2 out of the atmosphere, and several organizations sell carbon credits for planting trees. A rough calculation is that a tree will absorb about 50 pounds of CO2 for its lifetime of 40 years. (Then it gives it back, but that is another issue.) So to offset the 50,000 lbs of CO2 we produce each year, we would need to purchase 1,000 trees which would cost $3,000 through Green Horizons or $12,000 through Carbon Bank, The nice thing is that trees continue to grow, so this would in essence be a one-time purchase (or at least for 40-years).
