基于生命周期评价的宁夏出口枸杞干果产品碳足迹评价--以宁夏某企业为例

摘要

As the climate change conference agreement signed in Paris, “down-top” to address climate change become the main reduction mechanism of global climate governance process� Based on the theory of product carbon footprint calculation, using the method of life cycle assessment, life cycle greenhouse gas emissions of wolfberry product for export of a company in Ningxia were researched� The distribution of its carbon footprint were analyzed� Data base and suggestions were provided for enterprises to reduce greenhouse gas emissions in export wolfberry products� Results showed that wolfberry product carbon footprint of the company in Ningxia was the 2�224kg CO2 eq/kg, planting fertilizer, drying gas, product transportation, electricity, raw materials transportation, pesticides as well as the growing were accounted for 44% 20%, 18%, 9%, 8%, 1% of total emissions� Fertilizer and drying fuel were the main control of the product life cycle greenhouse gas emissions.%随着气候变化大会《巴黎协议》的签订，“自下而上”应对气候变化成为全球气候治理进程的主要减排机制。本文基于产品碳足迹核算理论，采用生命周期评价方法，以宁夏某企业为案例，研究宁夏出口枸杞干果产品生命周期温室气体排放，评价分析其碳足迹的分布构成，为企业减少出口枸杞产品的温室气体排放提供数据基础和措施建议。研究结果表明：宁夏某企业出口枸杞干果产品碳足迹为2�224 kgCO2 eq／kg，种植使用的化肥、烘干使用的天然气、以及产品运输、加工使用的电力、原料运输以及种植使用的农药分别占总排放的44％、20％、18％、9％、8％、1％，化肥和烘干燃料是控制枸杞产品生命周期温室气体排放的主要对象。
