臺灣木棧板碳足跡之研究

The study on carbon footprint of wooden pallets in Taiwan

本研究主要於探討臺灣木棧板產業之生命週期評估。針對木棧板的整個生命週期內的排放量進行分析。同時考慮進出口航運距離對碳排放的影響。研究結果指出，臺灣的木棧板進口主要來自臺灣自身出口再進口，其次來自拉脫維亞與中國大陸；每年總進口木棧板的排放量為1,409,524.16 kg CO2eq。然而木棧板的出口主要流向美國和中國大陸，每年總出口木棧板之排放量為84,669.83 kg CO2eq。綜合來看，臺灣的木棧板進出口產生1,324,854 kg CO2eq的碳足跡逆差。在航運運輸方面，木模板排放量高達1,055,234 kg CO2eq，這說明臺灣的木棧板產業過度依賴進口，造成了大量碳足跡排放。本研究建議政府應該更加重視國內木材市場，增加國產木材的利用，不僅延長木棧板的生命週期效益，還能夠減少能源的消耗，產生有助於減輕木棧板產業對進口的過度依賴，從而降低碳足跡的排放。

This study focuses on exploring the life cycle assessment and environmental impact assessment of Taiwan's wooden pallet industry’s imports and exports. A detailed investigation was conducted on the emissions throughout the entire life cycle of wooden pallets, including their reuse and carbon storage. Additionally, the influence of import and export shipping distances on carbon emissions was taken into account, and the contributions of shipping distances and total import/export quantities to overall emissions were calculated. The results show that the main source of imported wooden pallets in Taiwan is from its own exports and subsequent re-imports. The following sources are Latvia and mainland China. The total emissions from imported wooden pallets are 1,409,524 kg CO2eq. On the other hand, the main destinations for wooden pallet exports are the United States and mainland China, with a total emission of 84,670 kg CO2eq.Taken together, Taiwan's imports and exports of wooden pallets contribute to a carbon footprint deficit of 1,324,854 kg CO2eq. In terms of shipping transportation, emissions reach as high as 1,055,234 kg of CO2eq, underscoring the excessive import dependence of Taiwan's wooden pallet industry and the resulting substantial carbon footprint emissions. Based on the research findings, it is recommended that the government places greater emphasis on the domestic timber market and increases the utilization of domestically produced timber. This approach not only extends the lifecycle benefits of wooden pallets but also reduces energy consumption. This action would help alleviate the industry's overreliance on imports, thereby lowering carbon footprint emissions.
