摘要:

面对气候变化日益严峻的挑战,构建系统性、前瞻性的气候减缓评估框架正成为全球治理的重要课题。政府间气候变化专门委员会(IPCC)第七次评估报告(AR7)第三工作组(WGIII)在继承AR6成果的基础上,围绕政策适用性、治理维度与技术路径等关键领域进行了系统优化与议题拓展。AR7在引入政策事后评估、强化跨部门协同、完善绿色金融体系、加大对需求侧与社会公平的关注、独立设立碳去除与海洋系统章节等方面均体现出显著进步。文中在回顾AR7 WGIII会议过程与框架演进的基础上,系统梳理了AR6的主要贡献与评估局限,分析了AR7的重点改进方向及其政策内涵。结合中国气候治理实践,进一步提出推进政策评估、打破行业壁垒、深化绿色金融、优化消费减排、加快部署碳去除技术等建议,并指出我国应加强相关前沿领域研究,以更好支撑未来IPCC评估工作、增强在全球气候治理体系中的知识贡献与话语权。

Abstract:

As climate change intensifies, developing a systematic and forward-looking framework for climate mitigation assessment has become a critical issue in global governance. Building upon the foundations of the Sixth Assessment Report (AR6), the Working Group III (WGIII) of the Intergovernmental Panel on Climate Change (IPCC) has undertaken a comprehensive restructuring of its Seventh Assessment Report (AR7), focusing on improving policy relevance, governance dimensions, and technological pathways. Notable advancements in AR7 include the introduction of ex-post policy assessment, enhancing cross-sectoral integration, expanding analysis of green finance, increasing attention to demand-side strategies and social equity, and the establishment of dedicated chapters on carbon dioxide removal (CDR) and ocean-based mitigation. This paper reviews the development and structure of the AR7 WGIII framework, summarizes the key contributions and limitations of AR6, and analyzes the major areas of refinement in AR7. Drawing on China’s ongoing climate policy practices, the paper proposes targeted recommendations such as strengthening policy evaluation, breaking sectoral silos, deepening green finance reform, advancing demand-side mitigation, and accelerating CDR deployment. It further calls for enhanced research in critical frontier areas to better support future IPCC assessments and elevate China’s knowledge contribution and influence within the global climate governance architecture.
