CO2 only comprises something like 1%.

Only comprises .04% (four hundredths of a percent, 400 parts per million, .0004 of the total atmosphere) In other words....nothing.

Thanks for the assist. I knew it was a low number.

And besides, even if the rotting grass clippings does emit CO2, the remaining grass uses that as food to convert it into oxygen which mammals inhale and then we exhale CO2.

It's almost as if it's a cycle.
