Increased fuel means a lot more CO2. That is a very significant factor you cannot ignore.

Perhaps if herbicides weren't viable, more work would've gone into developing the mechanical alternatives and we'd have had solar-powered machines removing weeds from fields.

Soil resistance is worse than air resistance, but similar concept. It needs a lot of energy to overcome.

More CO2 compared to what tractors use today, yes. But that is not a lot compared to the rest of the human civilization spend on transportation.

So no, it is not a very significant factor.
