大米是日本最重要的农产品。它以各种形式消费，每种形式使用不同数量的资源和能源。本研究试图评估的生命周期的大米（良好和部分研磨，糙米，发芽糙米），并将其与蒸谷米，以确定是否可以减少环境负荷的大米的生命周期。从部分碾磨（碾磨2%）到蒸谷米，生命周期库存（CO2排放）逐渐增加。纸袋的选择似乎比聚乙烯袋的选择更环保。值得注意的是，与精米相比，部分精米不仅减少了环境负荷，而且保留了更多的食物营养素。大米生产和消费模式的改变将有助于减少约2-16%来自日本目前大米生命周期的负面环境影响。
Rice is the most important agricultural commodity in Japan. It is consumed in various forms, each of which uses different amounts of resources and energy. This study attempts to evaluate the life cycle of rice (well- and partially-milled, brown, and germinated brown rice) and compare it to the parboiled milled rice to determine if the environmental load from the life cycle of rice can be reduced. The life cycle inventory (CO2emission) increases gradually from partially-milled (milling 2%) to the parboiled rice. The paper-bag option seems to be more environmentally friendly than the polyethylene-bag option. It is worthwhile to note that the partially-milled rice not only reduces the environmental load but also retains more food nutrients compared to the well-milled rice. A change in rice production and consumption patterns would be helpful to reduce about 2–16% of the negative environmental impact coming from the current life cycle of rice in Japan.
