Abstract: Recent studies show that rural areas are becoming the second-largest source of greenhouse gas emissions, making the reduction of rural carbon emissions a growing focus of attention. The rural living environment encompasses production, living, and ecological spaces. This research proposes a quantitative model of carbon sources and carbon sinks in rural living environments with Xuanjiayuan Village in Tianjin as a case study. The study quantifies the carbon sources and sinks of the village's living environment, and finds that carbon emissions from rural production spaces are the primary source of rural carbon emissions. The research concludes that there is an imbalance between carbon sources and sinks in the rural living environment of Xuanjiayuan Village. Therefore, transforming the high-carbon production and living models and increasing carbon sinks in rural ecological spaces are key to creating a low-carbon rural living environment.

Key words: rural, carbon sources, Carbon Neutrality, quantitative comparison, compensation mechanisms
