FYI

零污染(zero-pollution)与无污染(non-pollution)应该有所不同。例如:

“电动汽车无内燃机汽车工作时产生的废气,不产生排气污染,对环境保护和空气的洁净是十分有益的,有"零污染"的美称。众所周知,内燃机汽车废气中的CO、HC及NOX、微粒、臭气等污染物形成酸雨酸雾及光化学烟雾。
电动汽车无内燃机产生的噪声,电动机的噪声也较内燃机小。噪声对人的听觉、神经、心血管、消化、内分泌、免疫系统也是有危害的。
  但是,使用电动汽车并非绝对无污染,例如使用铅酸蓄电池做动力源,制造、使用中要接触到铅,充电时产生酸气,会造成一定的污染。蓄电池充电所用的电力,在用煤炭作燃料时会产生CO、SO2、粉尘等。”

So,"零污染" can be literally rendered as "zero-pollution". As for the two kinds of "pollution",we  need other environment experts to explain.
