Carbon accounting of forest bioenergy
نویسندگان
چکیده
Via a detailed analysis and review of the currently available literature, this work aims at clarifying the phenomena, physical and mathematical, underpinning the methodologies and results in forest bioenergy carbon accounting. The large scale techno-economic models indicate that an increased forest stemwood removal for bioenergy purposes may cause either a decrease of the forest carbon stock (or a lower increase compared to the BAU) or displacement of wood for

An Investigation of the Carbon Neutrality of Wood Bioenergy
Wood biomass has been viewed as “carbon neutral”—its uses as energy have a zero carbon footprint. Some observers argue that the use of wood biofuels will result in a decrease of the forest stock and a net reduction of the carbon captured in the forest. Such assessments take a static, accounting view of forest systems and do not consider the effects of management in renewing the forest and incre...
متن کاملRegional carbon dioxide implications of forest bioenergy production
Policies are being developed worldwide to increase bioenergy production as a substitution for fossil fuel to mitigate fossil fuelderived carbon dioxide emissions, the main cause of anthropogenic global climate change4,5. However, the capacity for forest sector bioenergy production to offset carbon dioxide emissions is limited by fossil fuel emissions from this activity (harvest, transport, and ...
متن کاملIndirect carbon dioxide emissions from producing bioenergy from forest harvest residues
Forest harvest residues are important raw materials for bioenergy in regions practicing forestry. Removing these residues from a harvest site reduces the carbon stock of the forest compared with conventional stem-only harvest because less litter in left on the site. The indirect carbon dioxide (CO2) emission from producing bioenergy occur when carbon in the logging residues is emitted into the ...
متن کاملShort and long-term carbon balance of bioenergy electricity production fueled by forest treatments
BACKGROUND Forests store large amounts of carbon in forest biomass, and this carbon can be released to the atmosphere following forest disturbance or management. In the western US, forest fuel reduction treatments designed to reduce the risk of high severity wildfire can change forest carbon balance by removing carbon in the form of biomass, and by altering future potential wildfire behavior in...
متن کاملCorrecting a fundamental error in greenhouse gas accounting related to bioenergy
Many international policies encourage a switch from fossil fuels to bioenergy based on the premise that its use would not result in carbon accumulation in the atmosphere. Frequently cited bioenergy goals would at least double the present global human use of plant material, the production of which already requires the dedication of roughly 75% of vegetated lands and more than 70% of water withdr...
