You need to look at the whole cycle.

The carbon being used to create the CO2 when you burn vegetable oil was
taken from the air when the plants the oil came from took in CO2.
Therefore the net impact on CO2 levels is zero.

The carbon in fossil fuels came from the atmosphere as well -- but
millions of years ago.
