Abstract This experiment is designed in response to the growing volume of express deliveries in universities and is set against the background of low-carbon development.It focuses on the carbon footprint accounting of express packaging,aiming to deepen students’ understanding of the“dual carbon”goals.By calculating the carbon emissions throughout the full life cycle of express packaging and combining steps such as optimization scheme design,sample classification,sample collection,and data analysis,the carbon emissions of express packaging in universities can be quantified.The results show that the raw material production stage of express packaging emits 163 tons of CO2 equivalent(t CO2e) annually,accounting for 72% of the total emissions,recycling and reuse of materials are the most effective carbon reduction measures.Additionally,fossil fuel consumption during transportation is another significant contributor to the carbon footprint of express packaging,which can be mitigated by replacing conventional vehicles with those powered by clean energy.Through this experiment,students can not only master the methods of carbon footprint accounting but also gain an in-depth understanding of how different packaging materials,transportation processes,and waste disposal methods affect carbon emissions.The experiment enhances students’ awareness of low-carbon and environmental protection concepts,improves their comprehensive experimental skills,and inspires their interest in green development,while subtly strengthening their sense of environmental responsibility.
