Where do you report pollution caused by cabs ?

The photo below is what I’m taking about. Its a cab for the company Cognizant. You’d think they were cognizant about these things, but I’m sure they aren’t.

If anyone of you (who is reading this) knows the ideal place to report this? (I’m thinking, law enforcement/NGO’s dealing with this, etc.), drop me a line in the comments.

Another interesting aspect of this picture (which I realized when I was writing this post) is that the vehicle registration number is different at the back and at the side. Take a look yourself.

This is on the number plate on the back. The light wasn’t very good, but its surely not the same as what you see below.

I don’t know how to deal with these things. Conspiracy theory anyone?
