本研究は、カナダ・オンタリオ州北東部の遠隔地コミュニティにおいて、森林残渣や製材所残渣をバイオマス燃料として活用し、化石燃料を代替するバイオヒートの温室効果ガス削減ポテンシャルを評価した。電気式バイオヒートが最大の削減効果を示し、特に本来は野焼きされる森林残渣を利用した場合、100年間で−256.32 gCO2 eq·MJ−1の削減が可能である。すべてのシナリオで初年度からカーボンニュートラルを達成したが、社会的・経済的・運用上のリスクも指摘されている。
English
This study evaluates the GHG reduction potential of bioheat using woody residues (forest harvest and sawmill) in remote communities of northeastern Ontario, Canada. The largest emission reductions were found in electric bioheat scenarios using forest harvest residues that would otherwise be burned, achieving -256.32 gCO2 eq·MJ−1 over 100 years. All scenarios achieved carbon neutrality from the first year, but social, economic, and operational risks remain.

日本のGX文脈において
日本では、北海道などの遠隔地における灯油やプロパンガスからの燃料転換として、未利用木質バイオマスを活用したバイオヒートが注目される。本研究の手法や結果は、日本の遠隔地コミュニティでの脱炭素化戦略の参考となりうる。
In the global GX context
This paper provides empirical evidence on the GHG benefits of switching to bioheat in remote communities, which is relevant for global decarbonization of off-grid heating. It demonstrates that woody residues can yield immediate carbon neutrality, supporting bioenergy as a transitional solution in hard-to-abate sectors.

📄 Abstract（原文）
ABSTRACT Switching from high‐emitting fossil fuel to lower‐emitting biomass fuels is one approach to help to lower greenhouse gas (GHG) emissions. Most remote communities in Canada are primely positioned to take advantage of fuel switching for space heating as they are closer to sustainable biomass resources than urban areas. Furthermore, bioheat in remote communities can improve both environmental and socio‐economic outcomes by allowing communities to gain energy independence and security when using local renewable resources. This study examines the GHG emissions reduction potential of substituting fossil fuels with woody residues to produce heat in remote communities in northeastern Ontario, Canada. We examined both hydronic and electric heat using forest harvest and sawmill residues as biomass fuel types. We found the largest emission reductions in the electric bioheat scenarios, with the scenario using forest harvest residues that would have otherwise been burned showing the greatest emissions reduction potential (−256.32 gCO 2 eq·MJ heat −1 by 2124). Biomass fuel type rankings for all scenarios, regardless of heating system or fossil fuel substitution, are: forest harvest residues from burn slash piles > forest harvest residues from decay slash piles > sawmill residues. All scenarios were carbon neutral in the first year of bioheat production and remained so for the 100‐year study period. While our study showed the environmental benefit of fuel switching, social, economic, and operational risks of a project such as this should not be overlooked.
