Yes - *IF* the biomass is produced sustainably. If (as is happening in
developing countries already) the production of biomass adversely
affects the environment, such as by cutting down rainforest to make room
for canola crops, then you no longer have such a tidy zero-sum game.

Burning fuels also transport the pollution to where the people are. It
may be absorbed again, but not before it has passed through our lungs...
