8,200 ag pump produce over 14,000 tons of emissions per year? Diesel must be heavier when it is burned I guess.

You're right. The same goes for gasoline, natural gas, ethanol, etc., because of the way the environmentalists count Carbon dioxide but not Oxygen weight.

For example, let's burn methane in the presence of oxygen. 16 grams of methane magically become 44 grams of carbon dioxide emissions.
CH₄ + 2O₂ --> CO₂ + 2H₂O + heat
(16) + (64) --> (44) + (36) grams/mole

Clever chemistry!
