本稿は、再生可能エネルギー、グリーン水素、CCS、スマートグリッド、産業電化、循環経済技術が、EU・米国・日本・韓国など先進国の気候戦略の中核を成すと論じる。太陽光・風力の低コスト化や電池・系統デジタル化の進展、鉄鋼・セメント・化学での水素還元等の実証を整理。炭素価格やグリーン公共調達、IRA等の政策が導入を加速する一方、重要鉱物の供給網や人材移行、インフラ格差が課題と指摘する。
English
This review argues that green technologies—renewables, green hydrogen, CCS, smart grids, industrial electrification, and circular economy—are now central to climate strategies in the EU, US, Japan, and South Korea. It documents falling costs, scalability gains, and pilot breakthroughs in steel, cement, and chemicals, alongside policy drivers like carbon pricing, green procurement, and the US IRA. Remaining barriers include critical-mineral supply chains, workforce transitions, and infrastructure gaps.

日本のGX文脈において
日本を含む先進国の政策・技術動向を横断的に整理しており、SSBJ開示やGX推進法下での企業の移行計画策定、産業競争力と脱炭素の両立を考える上での参照枠を提供する。特に鉄鋼・セメント等の難脱炭素分野の技術実証は、国内製造業のScope1削減戦略に示唆を与える。
In the global GX context
The paper synthesizes how industrialized economies embed technology deployment into binding climate frameworks—EU Green Deal/Fit-for-55, the US IRA, and Asian industrial strategies—offering a comparative backdrop for ISSB/TCFD-aligned transition planning. It highlights that hard-to-abate sector innovation (hydrogen reduction, electrified kilns) is now a core disclosure and strategy concern globally.

📄 Abstract（原文）
Green technological advances are increasingly serving as the foundation for national climate strategies in industrialized countries, enabling ambitious emissions reductions while fostering economic growth, energy security, and industrial competitiveness. This study examines the role of key innovations — such as highefficiency renewable energy systems, green hydrogen, carbon capture and storage (CCS), smart grids, electrification of industry, and circular economy technologies — in shaping climate policies across leading economies, including the European Union, the United States, Japan, and South Korea. The analysis reveals that these technologies are no longer supplementary tools but central components of integrated decarbonization pathways, embedded in national energy strategies, regulatory frameworks, and investment plans. Empirical evidence shows that technological progress has significantly reduced costs and improved scalability, making green solutions economically viable at scale. For example, solar and wind power now offer the lowest levelized cost of electricity in most regions, while advances in battery storage and grid digitization support the integration of variable renewables into industrial energy systems. Industrial sectors such as steel, cement, and chemicals are piloting breakthrough technologies — including hydrogen-based reduction and electrified kilns — to decarbonize hard-to-abate processes. Policy mechanisms such as carbon pricing, green public procurement, innovation funding, and regulatory mandates have accelerated the deployment of green technologies. In the EU, the Green Deal and Fit-for-55 package link technological deployment with binding emissions targets, while the U.S. Inflation Reduction Act allocates over $370 billion to incentivize domestic clean tech manufacturing and deployment. Despite progress, challenges remain, including supply chain vulnerabilities for critical minerals, workforce transitions, infrastructure gaps, and international coordination. However, the convergence of technological maturity, policy support, and private investment demonstrates that green innovation is not only compatible with industrial growth but essential to long-term climate resilience. The findings underscore that sustained investment in research, development, and deployment of green technologies is the cornerstone of effective climate strategy in the industrialized world.
