Probably not. Just dump the "scrubbed" air out of tall chimneys, and it will mix nicely with the carbon-saturated ambient air. This is a slow, steady process which would have an impact over a long time frame.
Worst case the plants have to be in windy areas (for mixing) and possibly reduce output if it's dead calm. But that's probably not necessary, any more than people and animals get poisoned by the CO2 emitted from power plants or other industrial processes.
