摘　　要：【目的】评估竹笋产品碳足迹,挖掘竹笋产品减排潜力,促进产业低碳高质量发展。【方法】基于2022—2023年浙江省杭州市临安区、湖州市安吉县的实地调查数据,对5种不同类型的竹笋出口产品(调味笋、手剥笋、笋干丝、水煮笋、鲜食笋)种植、生产和分销阶段进行碳足迹评估,识别碳排放热点,进行减排路径设计,并基于情景假设计算减排量;结合中国2015—2023年竹笋产品出口情况,估算中国历年竹笋产品出口隐含碳排放与碳排放强度。【结果】①5种竹笋产品的碳足迹从大到小依次为调味笋(1.3874 kg·kg^(-1))、手剥笋(1.0107 kg·kg^(-1))、笋干丝(0.9274 kg·kg^(-1))、水煮笋(0.3249 kg·kg^(-1))、鲜食笋(0.1748 kg·kg^(-1))。碳足迹构成分析结果显示:5种竹笋产品的碳排放热点主要为农资投入、鲜笋运输、鲜笋加工和附加物投入。②2015—2023年中国的竹笋产品出口平均隐含碳排放为18.4820万t,平均碳排放强度为0.9669 t·万元^(-1)。③基于碳排放热点的减排情景设计显示:2023年5种竹笋产品碳足迹平均下降幅度为20.15%。【结论】不同类型的竹笋产品碳足迹差异较大;2015—2023年的竹笋产品出口隐含碳排放呈波动下降趋势;综合隐含碳排放强度呈波动上升趋势;竹笋产品碳排放热点各有差异,通过减排措施,碳足迹有进一步减排的潜力。图2表7参36.[Objective]This study aims to assess the carbon footprint of bamboo shoot products and explore their emission reduction potential,so as to promote low-carbon and high-quality development of the industry.[Method]Based on the field survey data from 2022 to 2023 in Lin’an District of Hangzhou City and Anji County of Huzhou City,Zhejiang Province,this study assessed the carbon footprint of five different types of bamboo shoot export products(seasoned bamboo shoots,hand-peeled bamboo shoots,dried bamboo shoots,boiled bamboo shoots,and fresh bamboo shoots)during the planting,production and distribution stages,identified carbon emission hotspots,designed emission reduction pathways,and calculated emission reduction based on scenario assumptions.The implied carbon emission and carbon emission intensity of bamboo shoot export products in China were estimated according to the export situation of bamboo shoot products in China from 2015 to 2023.[Result](1)The carbon footprint of the five bamboo shoot products from large to small was as follows:seasoned bamboo shoot(1.3874 kg·kg^(-1)),hand-peeled bamboo shoot(1.0107 kg·kg^(-1)),dried bamboo shoot(0.9274 kg·kg^(-1)),boiled bamboo shoot(0.3249 kg·kg^(-1)),and fresh bamboo shoot(0.1748 kg·kg^(-1)).The carbon footprint composition analysis showed that the carbon emission hotspots of the five bamboo shoot products were mainly agricultural inputs,fresh shoot transportation,fresh shoot processing and additive inputs.(2)From 2015 to 2023,the average annual implied carbon emission of bamboo shoot exports in China was 1.8482×105 t,with an average carbon emission intensity of 0.9669 tons per 10000 yuan.(3)The emission reduction scenario design based on carbon emission hotspots showed that the average decrease in carbon footprint of the five bamboo shoot products in 2023 was 20.15%.[Conclusion]There are significant differences in the carbon footprint of different types of bamboo shoot products.The implied carbon emissions of bamboo shoot products exported from 2015 to 2023 show
