湿地是地球上碳储量最大的陆地生态系统，其碳储量约占陆地生态圈总碳量的20%。
Wetlands have the largest carbon storage among terrestrial ecosystems on the earth, and are estimated to contain 20% of carbon in global terrestrial ecosystems.
我们的食物从农田运送到市场平均要经过1,500至2,500英里路，但是这些路途产生的碳量一般仅占食物总的产碳量的4%。
Our food travels from 1, 500 to 2, 500 miles on average from farm to supermarket, but that journey typically accounts for just 4% of a food's carbon footprint.
这种方式对总碳排放量的贡献依旧很大：占到将近总量的15- 17%，这比全世界所有交通工具——轮船，汽车，火车和飞机——所排出的碳量还要多。
And its contribution to emissions is still large: say 15-17% of the total, more than the share of all the world's ships, cars, trains and planes.
形成浮游动物净生产力的碳量是浮游植物总碳固定的8.2%。
The carbon amount forming zooplankton net (productivity) was 8.2% of the (total) carbon amount fixed by phytoplankton.
准均质充量压缩点火燃烧(QHCCI)方式占总燃料多数的预混合燃料以稀薄燃烧完成，故可能有很低的排放，尤其是碳烟和氮氧化物。
Quasi homogeneous charge compression ignition (QHCCI) combustion may be with low emissions, especially for soot and NO_X, according as the most fuel which is pre-mixed is lean burnt.
