How about trying to answer the points raised?....

Your points cannot be answered because they are too imprecise.
For example, you say they are more poluting, but I've no idea
what you mean by polution. For example, you might be considering
CO2 as a polutent, whereas I might not; you might be considering
glass as a polutent, whereas I might not, etc.
If you want a reasoned response, you need to make a reasoned
point in the first place.
