Consistent quantification of climate impacts due to biogenic carbon storage across a range of bio-product systems

摘要: Abstract Temporary and permanent carbon storage from biogenic sources is seen as a way to mitigate climate change. The aim of this work illustrate the need harmonize quantification such mitigation across all possible pools in bio- anthroposphere. We investigate nine alternative cases wide array bio-resource pools: annual crops, short rotation woody medium temperate forests, long boreal forests. For each feedstock type pool, we quantify cycle impact due skewed time distribution between emission sequestration fluxes Additional consideration albedo changes forests also illustrated for forest case. When characterizing with global warming potentials (GWP), find large variance results which attributed different combinations biomass systems. any pool does not always confer benefits: even when stored long-term durable product pools, outcome may still be undesirable sourced slow-growing feedstock. example, Norway Spruce furniture mean life 43 years, change 0.08 kg CO 2 eq per kg (100 year horizon (TH)) would result. It was found that negligible leakage atmosphere, resulting GWP factor necessarily − 1 stored. As an geological reservoirs no leakage, estimate − 0.56 kg TH) effects are included. GWPs range resource options considered indicates more accurate accounting will require case-specific factors derived following methodological guidelines provided recent manuscripts.
