## 1 Introduction  
Adopting a global perspective, the challenge of mitigating global warming through carbon emission reduction is one of the foremost issues confronting humanity. The 2022 Emission Gap Report by the United Nations Environment Program (UNEP) highlights a significant discrepancy between the international community's efforts and the objectives outlined in the Paris Agreement, with no reliable route currently identified to limit the temperature increase to 1.5 \({}^{\circ}\)C [1]. Furthermore, as indicated in the World Energy Statistical Yearbook 2022, the Asia-Pacific region contributes a substantial 52.3% to global carbon emissions, with China alone accounting for a significant 31.3% of the carbon emissions in the Asia-Pacific region, emphasizing its critical role in the dynamics of regional and global carbon emissions [2]. The report emphasizes that more robust climate action necessitates changes in both the private sector and individual consumption behaviors. Using a consumption-based carbon emission accounting method, it is estimated that approximately two-thirds of global carbon emissions are attributable to household activities [1]. Carbon emissions refer to the release of carbon dioxide and other greenhouse gases due to human activities. Successfully advancing carbon reduction efforts requires the ongoing motivation of micro-level entities, such as communities and residents, to actively engage in the process. In 2020, General Secretary [PERSON] announced at the 75 th session of the United Nations General Assembly that China aims to peak carbon dioxide emissions before 2030 and achieve carbon neutrality by 2060, known as the 'carbon peak and neutrality targets' [3]. However, current greenhouse gas reduction measures in the public life domain are relatively limited, primarily relying on ethical guidance from relevant authorities and voluntary public self-restraint [4]. The Carbon Generalized System of Preferences (CGSP) provides an effective solution to this issue. The CGSP emphasizes voluntary participation by stakeholders, with no legal requirements mandating compulsory involvement. It advocates the use of incentive strategies to continuously enhance public engagement in emission reduction behaviors, guiding the public to adopt a low-carbon and green lifestyle [5]. The core approach of the CGSP is to provide inclusive rewards for carbon reduction behaviors, using positive reinforcement to encourage public participation in carbon reduction activities. As the fundamental unit of social organization, communities play a crucial role in exploring community-based CGSPs, which are essential for achieving the \"dual carbon\" strategy objectives. In 2022, the \"14 th Five-Year Plan for Digital Economic Development\" promulgated by China's State Council explicitly called for the acceleration of the digital transformation of existing residential and community facilities, encouraging the simultaneous planning and construction of intelligent systems in new residential developments [6]. As digital technologies such as the Internet of Things, 5G networks, cloud computing, big data, and artificial intelligence continue to mature and expand, their integration into community development has become increasingly feasible [7]. This progress establishes the foundation for embedding digital technology in community construction, further enhancing the role of digital platforms in this domain. At present, the community CGSP is in its preliminary stage of development, leading to several challenges in micro-level carbon reduction efforts among individuals and households. These challenges include a limited range of carbon reduction methods, incomplete low-carbon scenarios, and a lack of diverse incentive mechanisms. Additionally, the existing community CGSP remains relatively traditional, lacking the integration of modern digital technologies, which is crucial for developing new carbon reduction strategies.
