When plants grow, they remove CO2 from the atmosphere and store
it in the plant tissues. When you burn veggie oil, that same CO2 is
released back into the air. It's a cycle, with the same CO2 being used
by the plants and released over and over.
The net quantity of atmospheric CO2 doesn't increase.

When you burn petroleum, you are releasing millions of years of
previously stored CO2  into the atmosphere, increasing the total
quantity of CO2 in the air...
