本文深入分析了循环经济在应对全球气候变化中的重要作用，指出发展循环经济已成为破解资源约束、推动碳减排的关键策略。循环经济不仅可以减少生产和废弃物管理阶段的温室气体排放，还可以支持可再生能源的零废转型，并提升气候适应能力。通过梳理循环经济的发展历程和原则演化，本文从全生命周期视角评估了循环经济助力建筑、乘用车、塑料等高耗材行业减排的潜力。最后，本文结合中国的政策环境和实践进展，提出了在中国进一步推动循环经济发展的具体路径和政策建议，包括促进循环经济与气候变化政策的协同发展、将循环经济纳入碳减排管理体系、加强对循环经济创新和基础设施的投资等，以推动实现中国的碳达峰和碳中和目标。
This paper analyzes the critical role of the circular economy in global climate change mitigation，positioning it as a key strategy for addressing resource constraints and reducing carbon emissions. It highlights how the circular economy can cut greenhouse gas emissions during production and waste management，support renewable energy transitions，and enhance climate adaptation. By tracing the development and evolution of circular economy principles，the paper evaluates its emission reduction potential across high-material consumption sectors such as construction，transportation，and plastics from a life-cycle perspective. Finally，it outlines specific pathways and policy recommendations for advancing the circular economy in China，including policy integration，incorporating circular economy principles into carbon management，promoting high-value material use，investing in innovation，and adjusting macroeconomic policies，to achieve carbon peaking and carbon neutrality targets.
