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 products. The calculation of biogenic CO2 correction factors or payback times provides results with a large range of variability that depends on the many different characteristics and assumptions on both the bioenergy system and the reference fossil system such as: the fossil fuel replaced, efficiency of the biomass utilization, the future growth rate of the forest, the frequency and intensity of biomass harvests, forest management, the initial landscape carbon stock. However, in most cases, the dedicated harvest of stemwood for bioenergy causes an actual increase in CO2 emissions compared to fossil fuels in the short-term (decades). In the long-term eventually it may generate GHG savings and become carbon neutral (from several decades to centuries). It can be concluded also that the carbon neutrality assumption for forest bioenergy may be misleading and it is fundamental to integrate all the carbon pools in the analysis (above ground biomass, below ground biomass, dead wood, litter, soil and harvested wood products) and their evolution in the time horizon of the analysis for both the bioenergy scenario and the counterfactual. A comprehensive evaluation of the climate impacts of dedicated harvest of stemwood for bioenergy has to integrate also all of the climate forcers (aerosols, ozone precursors and albedo). -- EU Bookshop.

Biofuel policies encourage the utilization of cellulosic feedstock, in particular wastes from agricultural production, and forest residues from processors and leftover of forestry harvest. However, the GHG balance of various forest residue utilization scenarios is not fully understood, including pile burn (controlled burning of excessive woody biomass), left onsite (decomposition of woody biomass onsite), bioelectricity, and biofuels, I constructed an integrated forest-bioenergy carbon flux framework under two mixed type fuel load reduction management scenarios. The integrated forest-bioenergy carbon flux framework captures both sequestration by the natural growth of trees and emissions by various sources, including processing of biomass, transportation of biomass, fire disturbance, production/combustion of biofuels, harvested wood product processing and usage, decomposition of biomass, landfill emissions, etc. I estimated the net GHG emission differences of various scenarios for the fate of the forest residue by incorporating data uncertainty, between these two management scenarios and the Business as Usual (BAU) scenario, which does not carry out any fuel load reduction treatment (removal of surface forest biomass), with a study period of 40 years using Placer County, California as a case study. After 40 years, pile burn scenario has the greatest GHG emission, while decomposition of woody biomass without utilization has the least net GHG emissions per hectare. However, the differences are very small and the uncertainty in assumptions in the other factors, particularly the net sequestration rate, fire return intervals, and fire emissions, are an order of magnitude larger. In other words, the net GHG differences among various pathways of utilizing forest residues are not significant in the face of uncertainty.

For thousands of years, forest biomass or wood has been among the main energy sources of humans around the world. Since the industrial revolution, fossil fuels have replaced wood and become the dominant source of energy. The use of fossil fuels has the disadvantage of increasing atmospheric concentrations of greenhouse gases (GHGs), especially carbon dioxide (CO2), with the consequent warming of global climate and changes in precipitation. In this context, the substitution of fossil fuels with renewable energy sources like forest biomass is among the ways to mitigate climate change. This book summarizes recent experiences on how to manage forest land to produce woody biomass for energy use and what are the potentials to mitigate climate change by substituting fossil fuels in energy production. In this context, the book addresses how management can affect the supply of energy biomass using short-rotation forestry and the conventional forestry applying long rotations. Furthermore, the book outlines the close interaction between the ecological systems and industrial systems, which controls the carbon cycle between the atmosphere and biosphere. In this context, sustainable forest management is a key to understand and control indirect carbon emissions due to the utilization of forest biomass (e.g. from management, harvesting and logistics, and ecosystem processes), which are often omitted in assessing the carbon neutrality of energy systems based on forest biomass. The focus in this book is on forests and forestry in the boreal and temperate zones, particularly in Northern Europe, where the woody biomass is widely used in the energy industry for producing energy.

Mobilisation of Forest Bioenergy in the Boreal and Temperate Biomes: Challenges, Opportunities, and Case Studies features input from key international experts who identify and analyze the main opportunities and roadblocks for the implementation of sustainable forest biomass supply chains in the boreal and temperate regions. It draws from responses to surveys that were sent to specialists from different countries, compares models of bioenergy deployment, and discusses different types of bioenergy carriers. Efficiency and profitability of the supply chain are analyzed and the scale and level of confidence of feedstock inventory estimates are highlighted. Logistics and ecological and socio-economic footprints are also covered. This book provides a synthesis of the scientific and technical literature on specific aspects of forest biomass supply chains, and quantifies future potentials in comparison to estimates provided by other sources and the targets for bioenergy production set by various organizations (IEA, IPCC, etc.). Finally, the book proposes recommendations for practitioners, policymakers, and future research. This approach makes the book especially relevant for professionals, policymakers, researchers, and graduate students in the field of bioenergy conversion and management, as well as those interested in sustainable management of natural resources. Presents foundational theory, examples and lessons learned, drawing on scientific and technical literature, as well as surveys conducted among stakeholders from various countries of the boreal and temperate biomes Provides best practices, insights, and recommendations through an integrative framework that encompasses various aspects of forest biomass supply chain, at different scales, and looking at a broad geographical and geopolitical range Compares contrasting history, policy context, and level of forest bioenergy development in several countries through several case studies Analyzes the efficiency and profitability of the supply chain, highlighting the scale and level of confidence of feedstock inventory estimates
