Does methane count? Because if it does, I'm going to grow beans and cabbage, then can the beans and make the cabbage into sauerkraut. I'll make a fortune (and a bit of noise).
P.S. Does lighting up the methane add or subtract from your carbon credits?
Adds. Methane is a much stronger "warming gas" than CO2, so converting methane to CO2 would reduce the "greenhouse effect".
