The evaluation system for assessing the benefits of community carbon inclusivity should be grounded in five essential principles. First, it must be scientifically robust and precise, anchored in solid scientific evidence and accurate data to accurately reflect the real-world impact of carbon inclusivity. Second, the system ought to be holistic, encompassing all facets of community carbon inclusivity to evaluate the comprehensive effect of initiatives. Third, practical feasibility is crucial, ensuring that indicators are straightforward to collect and assess, steering clear of overly complex or unfeasible methods. Fourth, the system should enable comparability, allowing for the assessment of benefits across different communities or projects, thus facilitating informed decision-making and efficient allocation of resources. Lastly, sustainability is key, with a focus on long-term benefits and ongoing development, to guarantee the enduring influence and benefits of carbon inclusivity projects within communities. Given the limited number of existing studies on community CGSP and the absence of relatively comprehensive authoritative data, this paper employs the Analytic Hierarchy Process (AHP) to assign weights to the indicators. It utilizes a questionnaire survey to

To establish a community CGSP benefit evaluation index system, it is first necessary to construct a judgment matrix. This paper determines the criteria layer, guideline layer, and indicator layer through collective discussions among experts and scholars. The energy system within the community carbon inclusivity framework assesses its impact on carbon reduction by tracking the decrease in energy usage, enhancing energy efficiency, and encouraging the adoption of renewable energy sources. Four indicators have been chosen for this purpose: the community's annual electricity usage, its annual water usage, the number of energy-efficient appliances, and the prevalence of solar-powered appliances. These indicators serve as benchmarks for the energy aspect of community carbon inclusivity benefits. Annual electricity consumption indicates the effectiveness of the community's electricity conservation measures, while annual water consumption evaluates the efficiency of water use, reflecting the community's efforts in conserving water resources. The count of energy-efficient appliances measures the community's commitment to energy-saving appliances, encouraging the selection of high-efficiency products. The rising number of solar-powered appliances showcases the community's endeavors in shifting away from traditional energy reliance. The technological system assesses the community's advancements in adopting low-carbon and clean technologies, including innovations in carbon reduction techniques, thereby positively influencing the community's tech-savviness. Within this system, the study identifies four key indicators: the garbage collection rate, the harmless treatment rate of household waste, interactions with community display devices, and the adoption rate of digital technology. The garbage collection rate evaluates the community's efficiency in segregating, collecting, transporting, and processing waste. The rate of harmless waste treatment reflects the community's environmental commitment in managing waste. The frequency of interactions with community display devices serves as an indicator of residents' engagement with innovative technologies and the community's endeavors in raising low-carbon consciousness through digital means. Lastly, the adoption rate of digital technology indicates the community's receptiveness to digital solutions, highlighting the potential trend of using such technologies for spreading low-carbon knowledge and practices.
