Good furnace produce little particulate emission so its almost on par with burning gas.
Biomass - so mostly wood, wicker or straw has all its carbon content coming from the air - they capture CO2 as they grow, when you burn them you release exactly the same amount of CO2, hence they're carbon-neutral.
