通过对番茄的生命周期分析，研究了番茄在栽培和流通过程中的CO2排放。比较了低温（LT）和气调包装（MAP）对产品品质的影响。公路和海运也进行了比较。种植和运输方法以及分配系统影响整个生命周期清单（生命周期指数、二氧化碳排放量）。温室产品的生命周期清单大于塑料覆盖下的产品，公路运输的产品大于海运的产品。产地与消费地的距离对LCI有显著影响。值得注意的是，如果番茄通过公路运输的距离小于2000公里，尽管这种运输在运输和储存过程中不需要任何冷却，但MAP包装在环境上不适合LT包装：如果海运超过1000公里，MAP将是更好的选择。因此，MAP是更好选择的距离取决于运输方式，因为两种运输方式在速度上不同，因此在排放上也不同。为了最大限度地减少LCI，需要将种植方式从温室改为塑料覆盖，运输方式从公路改为海洋，包装方式从LT改为MAP，这将减少日本每年约14 - 24万吨的CO2排放。
Life cycle of fresh tomato was evaluated to determine CO2emissions during its cultivation and distribution. Low temperature (LT) and modified-atmosphere packaging (MAP) were compared for their effect on quality. Road and sea transport were also compared. The method of cultivation and transport and the distribution systems affected the overall life cycle inventory (LCI, CO2emissions). Life cycle inventory was larger for greenhouse produce than for that raised under plastic cover and larger for produce transported by road than for that transported by sea. The distance between production and consumption area affected the LCI significantly. It is worthwhile to note that MAP would not be environmentally acceptable over LT packaging in the case of tomatoes transported by road over a distance shorter than 2000km although such transport does not require any cooling during transport and storage: MAP would be a better option in the case of sea transport beyond 1000km. The distance over which MAP is the better option is thus dependent on the mode of transport because the two modes of transport differ in speed and, therefore, in emissions. A change in cultivation from greenhouse to plastic cover, in transport from road to sea, and in packaging from LT to MAP is required to minimize the LCI and would abate approximately 0.14–0.24million tonnes of CO2emissions a year from Japan.
