This minimizes the entire life cycle carbon footprint of a product, providing a long-term emissions reduction solution, rather than looking at just one part of the cycle such as airfreight.

这便把一种产品整个生命周期中的碳排放减到了最低，由此提供了长期减少碳排放的方案。 这比只盯住产品周期中的一环——比如货物空运——要有效很多。

Particulate matter of black carbon is involved also in other different environmental problems, such as reduction of tropospheric ozone formation, hydrology cycle disruption and visibility impairment.

碳黑颗粒物还具有抑制对流层中臭氧形成、干扰局部地区水文循环和降低能见度的其他环境效应。
