And this is the best-case scenario. Of the 12 production modes analyzed, two would reduce annual CO2 emissions by only two tons, while the other ten actually increase total emissions – up to 14 tons per year.
因此我们减排的二氧化碳不是30吨而是最多4吨。这还是最好情况下的假设。在研究分析的12种生产模式中，两种的年度二氧化碳减排量仅为2吨，而其余10种则实际造成总排放量增加——增排的最大值每年达到14吨之多。
