Material production accounts for 23% of all greenhouse gas emissions. More efficient use of materials—through decoupling of services that support human well‐being from material use—is imperative as other emission mitigation options are expensive. An interdisciplinary scientific assessment of material efficiency and its links to service provision, material cycle management, and climate policy is needed to identify effective strategies and help design the policy framework required for their implementation. We present the resource efficiency–climate change (RECC) mitigation framework, a first step toward such a comprehensive assessment. RECC is based on dynamic material flow analysis and links the services provided (individual motorized transport and shelter) to the operation of in‐use stocks of products (passenger vehicles and residential buildings), to their expansion and maintenance, and to their material cycles to model mitigation strategies and analyze trade‐offs for environmental impacts along the products’ life cycle. A key innovation of RECC is the upscaling of product archetypes with different degrees of material and energy efficiency, which are simulated with engineering tools. We utilize RECC with augmented storylines of the shared socioeconomic pathways to describe future service demand and associated material requirements. Ten material efficiency strategies at different stages of the material cycle can be assessed by ramping up their implementation rates to the identified technical potentials. RECC provides scenario results for the life cycle impacts of ambitious service–material decoupling concurrent with energy system decarbonization, giving detailed insights on the RECC mitigation nexus to policy‐makers worldwide.

将服务提供与物质周期联系起来：研究资源效率-气候变化（RECC）关系的新框架

材料生产占所有温室气体排放量的23％。迫切需要更有效地利用材料（通过将支持人类福祉的服务与材料使用脱钩），因为其他减排措施价格昂贵。需要对材料效率及其与服务提供，材料周期管理和气候政策之间的联系进行跨学科的科学评估，以识别有效的策略并帮助设计实施这些策略所需的政策框架。我们提出了资源效率-气候变化（RECC）缓解框架，这是进行这种全面评估的第一步。RECC基于动态物料流分析，将提供的服务（个人机动运输和庇护所）与使用中的产品库存（客运车辆和住宅建筑物）的运营联系起来，他们的扩展和维护，以及他们的材料周期，以建模缓解策略并分析产品生命周期内对环境影响的权衡取舍。RECC的一项关键创新是使用不同的材料和能源效率程度的产品原型升级，并使用工程工具进行模拟。我们将RECC与共享的社会经济途径的故事情节结合起来来描述未来的服务需求和相关的物质需求。可以通过将其实施率提高到已确定的技术潜力，来评估材料周期不同阶段的十种材料效率策略。RECC为宏伟的服务与材料脱钩以及能源系统脱碳的生命周期影响提供了情景结果，
