Ummm, seems to me that 0.42 acres of trees would sequester a lot more that 22kg of CO2 per year. Let me guesstimate from my typical annual hedge clipping - we have a (appx) 1.5m wide hedge that is (appx) 120m long equal to (appx.) 180m^2=0.044 acres. The annual clipping produces 10 hefty bags (the big bags used to carry e.g. 1 ton of gravel or stones), so maybe a total of 300-400kg for my hedge. Multiply by ten for 0.42 acres, yields about 3000-4000kg.

Sanity check anyone?

Unless it was edited...that sentence says 22kg per year each. So it's 22*220.
