A Comprehensive Review of Factors Influencing Carbon Sequestration Potential of Green Roofs and Environmental Benefits in Their Full Life Cycle
The construction of urban rooftop greening is a new approach with growing prevalence to increasing urban green space and improving the ecological environment of urban areas. However, the ecological and environmental benefits of green roofs are influenced by various factors. How to quantitatively analyze the factors influencing the carbon sequestration potential of green roofs, so as to maximize the ecological benefits of oxygen release by carbon sequestration, is one of the scientific problems demanding prompt solution in the roof greening construction currently. Based on a literature review, this paper explored the effects of such influencing factors like the vegetation planting layer, the soil substrate layer, building types, and climatic conditions on the carbon sequestration effectiveness of green roofs. The analysis revealed that green roofs can obtain carbon storage through plant and soil carbon sequestration, while lowering carbon emissions by improving the building's performance in thermal insulation to reduce its energy consumption and demand for fossil fuels. However, green roofs are also associated with embodied carbon emissions related to the production and transportation of materials, construction and demolition, and in the operational stage. Therefore, there is a need to further refine the full life cycle analysis methods for assessing the carbon sequestration potential of green roofs, develop accounting models for carbon sequestration levels, and conduct quantitative studies on the overall environmental benefits throughout the full life cycle of green roofs. This paper provides a basis for the analysis and evaluation of the promotion and application of green roofs.
