Abstract: Measuring carbon emissions of garden stone paving materials is an important part of quantifying the carbon emission in the garden construction period.In order to reduce the CO₂ emissions and achieve a reduction of energy consumption in landscape engineering, the converting from qualitative evaluation to quantitative measurement was used in this article and granite, the most commonly used garden stone was illustrated here to be divided into several stages as: production and processing stage,planning and design stage,construction stage,operation and maintenance stage, removal and recovery stage based on life cycle analysis(LCA). The establishment of the carbon emission measurement model in the stone paving process was on the basis of the measurement research of carbon emissions at micro-scale. The carbon emissions for an area of 2 308 m² granite pavement of tennis court in the Nanjing Institute of Physical Education and Sports was 12 436.73 kg,when above model was used to calculate carbon emission of its pavement in various life cycle stages at a micro-scale.And after analyzing the causes of carbon emissions, the corresponding measures for reducing the carbon emissions were put forward. In order to get reduction of emission,the emphasis should be focused on the construction and maintenance stage.
