本論文は、ネットゼロ計画が排出ゼロ電力、バイオマス、炭素貯蔵の3つの基本資源に依存していることを示す。包括的な計算機を用いて、これらの資源の需要と2050年の供給可能性を比較し、ほとんどの計画が過大な資源拡大を必要とすることを明らかにした。代わりに、最終需要の変化を含む実現可能な経路を提案する。
English
This paper reveals that all net-zero plans depend on three fundamental resources: emissions-free electricity, biomass, and carbon storage. A comprehensive calculator compares aggregated demands against likely global availability in 2050, showing most plans require improbable resource expansion. An alternative mitigation plan with end-user demand changes is proposed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のネットゼロ目標（2050年カーボンニュートラル）も同様の資源制約に直面する。本論文の分析は、日本のエネルギー基本計画やバイオマス利用、CCS戦略の現実性を検証する上で重要な指標を提供する。
In the global GX context
Globally, many net-zero pledges rely on 'invisible technology substitutions' without accounting for resource constraints. This paper provides a rigorous framework to assess the feasibility of such plans, relevant to TCFD, ISSB, and national climate strategies.
👥 読者別の含意
🔬研究者:Provides a quantitative framework to evaluate resource demands of net-zero pathways, useful for modeling and policy analysis.
🏢実務担当者:Highlights risks in relying on unproven technologies; for corporate sustainability teams, emphasizes the need to consider resource availability in decarbonization plans.

📄 Abstract（原文）
Most proposals for mitigating climate change assume that economic demand should grow without constraints so depend primarily on technology innovations to substitute today’s activities with emissions-free alternatives. However, the potential for such “invisible technology substitutions”, which could allow high-resource lifestyles to continue unchanged, is often overstated and disguised by burden-shifting. For example, plans may depend on synthetic fuels without accounting for its supply, or on negative emissions technologies without accounting for their power or land area requirements. Here, we show that all net-zero plans depend fundamentally on three resources: emissions-free electricity, biomass, and carbon storage. Using a comprehensive calculator, we reveal the high risk of shortages of these fundamental resources by comparing aggregated demands of net-zero plans, published by business, government, and industry bodies, against likely global availability in 2050. The calculator builds on physical models of 170 processes derived from an extensive literature search. Our results demonstrate that most climate policy proposals, which depend primarily on “invisible technology substitutions”, require an improbable expansion of the fundamental resources in the time available, indicating significant risks of under-delivery. We demonstrate an alternative mitigation plan built on a credible forecast of resource availability, revealing overlooked opportunities for innovations in policy, service supply, and financing: feasible zero-emission futures necessitate end-user participation and changed economic demand, which are largely disregarded in current international policy discussions.
