Biomass-based carbon dioxide (CO2-bio)

Biomass-based carbon dioxide emissions are generated from biomass burning. Biodegradation, for example at landfills and in wastewater treatment, also causes biomass-based CO2 emissions but they are not evaluated separately. Biomass includes wood, biogas, sludge from wastewater treatment and biodegradable waste. In Finland, most of the biomass-based CO2 emissions from burning are generated by burning of black liquor in the forest industry. Burning of other wood-based biomass is also a major source. Biomass-based CO2 emissions from burning are not included in energy sector emissions in the greenhouse gas inventory because they are included in carbon stock changes in the land use sector.
