NOT CO2 emissions

Its worse in volatile organics, particulates and NOx. Mostly volatile organics due to the two stroke cycle.

But not because a chainsaw is particularly bad, but because a Camry is exceptionally good.

Why is the Camry good? Because it has a four stroke, fuel injected, computer controlled engine and $300 of catalysts breaking everything down. The smoke of the Camry's emissions is water condensing out.

Not just water. A lot of CO, CO2, particulates and NOx are also emitted, especially at lower engine temperatures.

I was referring to smoke specifically the visually imposing clouds car produce which forms our image of car emissions. Of what you listed, only particulates add to the smokiness of a modern engine and then only when its cold. Unless its broken.
