Outline of Final Research Achievements

This study constructed a model to assess the overall carbon emission reduction effects (carbon storage, material substitution, and energy substitution) and environmental impact reduction effects (climate change, photochemical oxidant, resource consumption, acidification, waste, ozone layer depletion, eutrophication, ecotoxicity, land use, urban air pollution, indoor air pollution, human toxicity, and noise pollution) of wood use in regions of Japan. The model allowed for projections to 2050 based on multiple future scenarios relating to the domestic forestry, wood product use, and energy use.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、国際的な地球温暖化対策の枠組みにおける日本の木材利用による貢献ポテンシャルを明らかにしたと同時に、国内の林業・木材産業の環境貢献の大きさを明示したことにより、これらの産業や地域の活性化にも寄与できると考えられる。また、日本全体および各地域における炭素排出削減効果および環境影響削減効果を総合的に解明できるモデルを構築したことから、日本政府および地方自治体における木材利用の推進による効果的な政策の立案に貢献できる。
