| Title | Carbon Footprint Study of Organic Rice Product | ||
| Keyword | |||
| Abstract | Abstract The study focus on the calculation of carbon footprint (CFP) of organic rice product, produced in the first crop season in Taoyuan County in northern Taiwan. Function unit of CFP is per kilogram of rice. The organic rice product was verified by FSI Taiwan-Asia Pacific Office and was certified with a CAS organic agriculture product level. Life cycle of the organic rice product is divided into five stages: respectively as raw materials, manufacture, distribution and retail, consumer use, disposal and recycling. The agriculture activities and carbon emission factors were collected in the case study. Result of the case study shows that CFP of organic rice product is 1.86 kg CO2eq per kilogram of rice, and carbon emission respectively in five-stage of life cycle are: raw materials 1.38 kg CO2eq/kg (74.37%), manufacture 0.05 kg CO2eq/kg (2.95%), distribution and retail 0.01 kg CO2eq/kg (0.69%), consumer use 0.37 kg CO2eq/kg (19.96%), recycling and disposal 0.04 kg CO2eq/kg (2.03%). In comparison to CFP, 1.914 kg CO2eq/kg, of Japanese ordinary rice product produced in Chiba Area. Those are 0.08% in difference. Major portions of carbon emissions of organic rice product are from fertilizer products (25.43% of total carbon emissions), CH4 and N2O emissions from paddy field (19.97%), cooking power (19.96%), usage of metal and wood materials (4.09%), and packing material (3.14%). In addition to CFP calculation of organic rice product, an ordinary rice product produced in Hualien county, in estern Taiwan, shows that CFP of ordinary rice product is 2.32 kgCO2eq/kg. These are only used for comparison between organic farming and conventional farming of rice production. |
