Hi Firenice. Welcome to the English Forums.
Are you talking about a real mechanism (a mechanical gadget) or are you using the term figuratively?
The use of vehicles impinges on the lives of men and women by effecting the air they breathe. Our plan takes a three-step approach to dealing with this problem: (1) emission, (2) diffusion, and (3) attainment.
I'm really just guessing at what you're trying to say.
Best wishes, - A.
