本研究は、統合評価モデルと将来のライフサイクル評価を組み合わせ、地球規模のエネルギー利用による生態系と健康への影響を定量化した。脱炭素化の強化は大きな環境便益をもたらすが、バイオエネルギーと鉱山廃棄物から副作用が生じる。バイオマス利用の制限や鉱山廃棄物処理の改善などの介入が、副作用を抑制し、気候中立システムの全体的な便益を確認できると示した。
English
This study combines Integrated Assessment Modeling with prospective Life Cycle Assessment to quantify environmental impacts from global energy use. It finds that increased decarbonization yields major environmental co-benefits, but adverse side effects arise from bioenergy land use and mining toxicity. Targeted interventions like limiting biomass and improving mining tailings treatment can keep impacts below a weak policy baseline, confirming overall benefits of climate-neutral systems.

📄 Abstract（原文）
Abstract Transitioning our energy systems away from fossil fuels is vital for mitigating anthropogenic climate change. While defossilization brings co-benefits for many other environmental impacts, such as air pollution and acidification, there are significant concerns about adverse environmental side effects due to land, water, and material requirements of scaling up low-carbon energy technologies. Here, we combine Integrated Assessment Modelling with prospective Life Cycle Assessment to quantify environmental impacts on aggregate ecosystem and human health damages from global energy use. Our scenario analysis shows that compared with continuing current policies, increased decarbonization efforts yield major environmental co-benefits. Adverse side effects arise mainly from land requirements for bioenergy, and toxicity impacts from the mining tailings and metallurgical slags. We find that dedicated interventions can limit the environmental impacts from a low-carbon energy system to below the level implied by a weak policy baseline. These interventions include, in particular, limiting biomass use, phasing out first-generation biomass, and improving the treatment of mining tailings and slags. To a lesser degree, sustained metal recycling efforts and stronger air pollution control in the shipping and residential sectors contribute to further reductions. Our results demonstrate the overall co-benefits of climate-neutral energy systems and highlight supply-chain entry points to minimize trade-offs. These findings strengthen the case for more stringent climate change mitigation efforts in times of critical importance, yet uncertain global commitment.
