🤖 gxceed AI 要約

日本語

本レビューは、ネットゼロ構築を遅らせる5つの供給制約（許認可、資本集約性、重要鉱物、社会的受容性、モデリング）を整理し、需要側のサービスベースの十分性（Avoid-Shift-Improve）がこれらの制約を緩和し、プロジェクト数を減らし、資金調達可能性を高めることを示す。ネットゼロ経路の信頼性には、需要側設計を計画変数として組み込むことが重要と結論付ける。

English

This review synthesizes evidence on five supply-side constraints slowing net-zero buildouts (permitting, capital intensity, critical minerals, social contestation, modeling) and argues that service-based sufficiency (Avoid-Shift-Improve) can reduce project counts, ease material pressures, and improve bankability. It concludes that credible net-zero pathways must treat demand-side design as a core planning variable alongside clean energy supply.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本のGX政策では、需要側のエネルギーサービス削減（省エネ、シェアリング）が供給拡大と並ぶ柱となる可能性を示唆。SSBJ開示や移行計画策定において、需要想定の現実性が投資家評価に影響する点で示唆に富む。

In the global GX context

Globally, this review challenges supply-centric net-zero modeling by highlighting delivery constraints and demand-side sufficiency. It informs ISSB-aligned transition planning and climate risk assessments by emphasizing the credibility of pathways that integrate demand reduction, relevant for regulators and investors evaluating transition plans.

📄 Abstract（原文）

: Limiting warming to the Paris temperature goals requires a rapid scale-up of low-carbon energy, yet recent experience suggests that deployment is increasingly shaped by delivery constraints rather than by technology cost trends alone. This review synthesizes peer-reviewed evidence on five constraints that repeatedly slow net-zero buildouts: lengthy approval and grid-connection processes; capital-intensive investment profiles that heighten sensitivity to the cost of capital and revenue risk; bottlenecks in critical minerals, processing, and manufacturing; social contestation and local governance that translate into siting exclusions, delays, and cancellations; and modeling traditions that can underrepresent these non-marginal frictions. Accordingly, we adopt an energy-services perspective to examine how demand-side strategies affect the scale and timing of the required buildout. We interpret degrowth as service-based sufficiency, rather than as a blanket reduction in welfare, and organize the evidence using the Avoid, Shift, Improve (ASI) sequence. Across sectors, the reviewed literature indicates that lowering baseline service demand and, in particular, peak requirements can reduce project counts and network upgrades, limit exposure to interconnection queues and permitting backlogs, ease upstream material pressures, and improve bankability under risk-averse finance. We conclude that net-zero pathways are more credible when service provision and demand-side design are treated as core planning variables alongside clean-energy supply expansion.
