Localized carbon reduction strategies are especially critical in states and regions that lack top-down climate leadership. This paper illustrates the use of coupled systems in assessments of subnational climate solutions with a case study of Georgia, a state located in the southeastern United States that does not have statewide climate goals or plans. The paper illustrates how robust place-specific plans for climate action could be derived from foundational global and national work and by embedding that research into the context of socio-ecological-technological systems. Our replicable methodology advances the traditional additive sectoral wedge analysis of carbon abatement potential by incorporating solution interdependencies and by spanning both carbon sources and sinks. We estimate that a system of 20 solutions could cut Georgia’s carbon footprint by 35% in 2030 relative to a business-as-usual forecast and by 50% relative to Georgia’s emissions in 2005. We also produce a carbon abatement cost curve that aligns private and social costs as well as benefits with units of avoided CO₂-e. The solutions are affiliated with various social co-costs and co-benefits that highlight societal concerns extending beyond climate impacts, including public health, environmental quality, employment, and equity.

在缺乏自上而下的气候领导力的州和地区，本地化的碳减排战略尤其重要。本文以佐治亚州为例，说明耦合系统在评估地方气候解决方案中的使用，佐治亚州位于美国东南部，没有全州范围的气候目标或计划。该论文说明了如何从基础的全球和国家工作以及通过将该研究嵌入到社会-生态-技术系统的背景中来制定针对具体地方的气候行动计划。我们的可复制方法通过结合解决方案的相互依赖性和跨越碳源和碳汇，推进了碳减排潜力的传统附加部门楔形分析。_2- e。这些解决方案与各种社会共同成本和共同利益相关，突出了超出气候影响的社会问题，包括公共卫生、环境质量、就业和公平。
