2024年の世界のクリーンエネルギー投資は2.1兆ドルに達したが、ネットゼロ達成には4.8兆ドルが必要。本論文は、40カ国のデータを用いてカーボンプライシング、政策介入、市場構造が投資に与える影響を分析。カーボンプライスが50ドル/tCO2e以上で投資弾力性が向上し、政策不確実性は投資を18-32%遅延させる。分散ポートフォリオとアンカー投資家の効果を実証し、国有石油会社向け戦略枠組みを提案。
English
Global clean energy investment reached $2.1 trillion in 2024 but needs $4.8 trillion for net-zero. This multi-method analysis across 40 economies shows carbon price elasticity of 0.43 with a threshold effect above $50/tCO2e, policy uncertainty causing 18-32% investment deferral, and diversified portfolios offering superior risk-adjusted returns. Anchor investors trigger up to 3.2x capital multipliers. Proposes a Strategic Climate Investment Framework for national oil companies.

日本のGX文脈において
日本のカーボンプライシングはまだ低いが、本論文の閾値分析は今後のGX政策設計に示唆を与える。また、国営石油会社向けの戦略的枠組みは、日本のエネルギー企業（JOGMEC等）にも応用可能。政策不確実性の悪影響は、日本のGXリーグや排出量取引制度の安定性にも関連。
In the global GX context
This paper provides critical empirical evidence on the carbon price threshold ($50/tCO2e) needed to accelerate clean tech investment globally. Its findings on policy uncertainty and anchor investor dynamics are highly relevant for TCFD/ISSB-aligned transition planning and for sovereign wealth funds, NOCs, and independent operators designing climate technology portfolios.
👥 読者別の含意
🔬研究者:Offers rigorous multi-method evidence on carbon price thresholds and policy uncertainty effects, with novel use of real options and agent-based modeling to explain investment dynamics.
🏢実務担当者:Provides portfolio optimization insights for building resilient climate technology portfolios and understanding anchor investor multiplier effects to de-risk investment decisions.
🏛政策担当者:Demonstrates that carbon prices above $50/tCO2e significantly boost clean tech investment, and reducing policy uncertainty could unlock substantial deferred capital.
📄 Abstract（原文）
Abstract Global clean energy investment surpassed USD 2.1 trillion in 2024 and an 11% year-on-year increase, yet current trajectories fall far short of the USD 4.8 trillion annual investment required to align with a net-zero pathway by mid-century. This paper presents a rigorous multi-method analysis of climate technology investment dynamics, examining how carbon pricing mechanisms, direct policy interventions, and evolving market structures collectively shape capital allocation decisions across the energy sector. Employing an integrated analytical framework combining Real Options Analysis (ROA), panel data econometrics, mean-variance portfolio optimization, agent-based modeling (ABM), and technology experience curve analysis, we interrogate investment behavior across 40 major economies over the 2010–2024 period using data from the International Energy Agency (IEA), BloombergNEF, the World Bank Carbon Pricing Dashboard, and IRENA. Our panel econometric results reveal a statistically significant positive elasticity of 0.43 between carbon price levels and clean technology investment intensity, but with a threshold effect: investment response accelerates materially above a carbon price of USD 50/tCO2e, a level currently exceeded by fewer than 20% of emitting jurisdictions. Real options modeling demonstrates that policy uncertainty creates an investment deferral premium of 18–32% on climate technology projects in medium-ambition jurisdictions, representing substantial foregone capital deployment. Portfolio optimization analysis identifies diversified climate technology baskets spanning solar, grid storage, hydrogen, and CCS that offer superior risk-adjusted returns relative to single-technology concentration under all carbon price scenarios examined. Agent-based model simulations reveal tipping points in investment momentum when anchor investors, sovereign wealth funds and national oil companies signal technology commitment, generating up to 3.2x capital multiplier effects through follower behavior. Informed by this evidence base, we propose a Strategic Climate Investment Framework (SCIF) designed to guide national oil companies (NOCs) and independent operators in constructing resilient, value-accretive climate technology portfolios under conditions of persistent policy and market uncertainty.
