New method to account for CO2 emissions from biomass combustion in bioenergy systems

CO2 emissions resulting from bioenergy production have traditionally been excluded from most emission inventories and environmental impact studies because bioenergy is carbon- and climate- neutral as long as CO2 emissions from biofuel combustion are sequestered by growing biomass. Its climate impact has not therefore been considered.

Cherubini and coauthors propose that CO2 emissions from biomass combustion for bioenergy should no longer be excluded from Life Cycle Assessment studies or be assumed to have the same global warming potential as anthropogenic CO2 emissions. Carbon dioxide is emitted when biomass is burnt and the sequestration in the new vegetation can be spread for up to several decades in the case of slow-growing biomass, like forests.
