Outline of Research at the Start

地球温暖化問題において、木材の炭素貯蔵、材料代替、燃料代替による炭素排出削減の可能性が世界的に注目されている。本研究では、世界各国の木材のフロー・ストックに関わる炭素貯蔵、材料代替、燃料代替による総合的な炭素排出削減効果を推計できるモデルを世界に先駆けて開発する。この世界モデルにおいて、木材利用に関わる複数の政策シナリオを検討し、世界各国・世界全体の炭素排出削減効果の将来予測を行い、効果的な温暖化対策とその削減ポテンシャルを提示する。本モデルの開発により、各国の木材利用に関わる政策案に応じて、温暖化対策への貢献ポテンシャルの定量予測が可能となり、効果的な政策の決定を支援するツールを提供できる。

Outline of Final Research Achievements

This study conducted future projections of global carbon emission reduction through carbon stock, material substitution, and energy substitution associated with wood flow and stock in each country of the world. We found that global carbon stock in wood products will reach 11.0-15.2 billion t-C in 2050 from 7.4 billion t-C in 2018. With policies promoting waste wood recycling, substituting steel and concrete products with wood products, and substituting coal with wood fuel, global carbon emission reduction will be 0.8-2.3 billion t-CO2/year in 2050 compared to that in 2018.

Academic Significance and Societal Importance of the Research Achievements

世界各国を対象として木材利用による炭素貯蔵、材料代替、燃料代替による炭素排出削減効果を総合的に推計できるモデルはこれまで存在せず、本研究はその推計モデルを世界に先駆けて開発した。これにより、今後の世界における社会経済経路や木材利用に関わる政策のシナリオに応じて温暖化対策への貢献ポテンシャルの将来予測が可能となったため、各国における効果的な政策決定を支援するツールを提示できた。
