面向双碳目标的典型园区碳排放计算分析

园区是我国城市碳排放的主要场所,厘清园区级碳排放源/碳汇构成是开展园区低碳路径研究的关键。目前,国内外还未发布园区级碳排放计算相关规范或指南,已开展的研究大多针对存量的某一特定类型园区碳排放进行计算分析,未充分考虑新建园区的数据可得性以及计算体系对不同类型园区的适应性问题。因此,开展了计及多类型园区特征的碳排放计算方法研究,从能源活动（覆盖农业、工业、建筑、交通、旅游设施、其他公共基础设施等）、农业生产、工业生产、废弃物处理、绿植碳汇5个维度构建园区级碳排放计算体系,并分别给出数据完备和数据缺失情况下的计算公式。算例表明,所提方法对特色农业型园区、工业制造型园区、商务办公型园区、旅游休闲型园区等多类型园区的碳排放总量计算以及结构分析均适用。

Dual-carbon-targets-oriented calculation and analysis of carbon emissions for typical parks

Parks are the main source of urban carbon emissions in China. To clarify the composition of park- level carbon emission sources or sinks is the key to carrying out research on low-carbon pathways for parks. At present, there are no park-level carbon emission calculation-related norms or guidelines at home and abroad. Most of the research that has been carried out is to calculate and analyze the carbon emissions of a specific type of stock park, without fully considering the data availability of new parks or the adaptability of the calculation system to different types of parks. Therefore, a park-level carbon emission calculation method considering the characteristics of various types of parks is proposed. The calculation system is constructed from five dimensions,including energy activities (covering agriculture, industry, construction, transportation, tourism facilities, power infrastructure, etc.),agricultural production, industrial production, waste treatment,green plant carbon sinks. The calculation formulas for both complete data scenario and missing data scenario are respectively proposed as well. Case study shows that the proposed method is applicable to the calculation of total carbon emissions and structural analysis of various types of parks such as agricultural parks, industrial manufacturing parks, business parks, and tourism parks.
