Abstract: In the context of China’s response to global climate change and the national strategic goals of “carbon peak and carbon neutrality”, high carbon emissions during the construction phase of production and construction projects have become a significant factor restricting the green transformation and development of the industry. The dual carbon work of soil and water conservation in production and construction projects mainly faces three scientificchallenges: insufficient exploration of the functions of soil and water conservation in carbon sink enhancement and emission reduction, the lack of an integrated system, and the high energy consumption of soil and water conservation measures during material production and construction processes. This study aims to establish an integrated technical system for soil and water conservation, carbon sequestration, carbon sink enhancement, and emission reduction in production and construction projects. A full-life-cycle low-carbon value-oriented approach was proposed, integrating three core concepts: enhancing ecological carbon sink function, promoting low-carbon utilization of resource recycling, and supporting transformation through technological innovation. The approach focused on three-dimensional governance—carbon sink enhancement, soil conservation for carbon sequestration, and energy conservation and emission reduction. A dual carbon management model was innovatively formed for soil and water conservation characterized by “precise resource targeting—scientific strategy formulation—strengthened full-life-cycle implementation”. Key technologies for soil and water conservation were innovatively proposed in production and construction projects, such as carbon sink enhancement, soil conservation for carbon sequestration, and emission reduction. These technologies were deeply integrated into the entire process from the preliminary design to subsequent construction and acceptance. Additionally, this study explored the construction of a carbon footprint monitoring system for typical areas of human-induced soil erosion control in China. The study provides theoretical support and technical pathways for integrating soil and water conservation in production and construction projects with the “dual carbon” goals, facilitating the green and low-carbon transformation of related industries.
