With due respect, I have quoted Suzuki website, and you are talking from the top of your head, and still, I am the one who is spreading false information. I don't know how that makes sense.
Firstly, I mentioned in my first post that the engine is euro6 compliant. And I mentioned that our fuel is not, which means that emissions are not as per euro6 here in Pakistan, but if the requisite fuel quality is provided, it will be compliant with euro6.
Secondly, emissions control mechanism has more to it than just catalytic converters and ECU programming. Sometimes, the same engine can fulfill requirements of a more stringent emissions compliance regime by simply adding catalytic converter or remapping the ECU. At other times, it goes beyond that, to the way pistons and valves are designed. So, it is not necessary that adding a catalytic converter will make a car compliant to some standard and removing it will not. It might be true in some cases, but there are other factors that are at play here.
And lastly, I don't see any need for PakSuzuki to downgrade the engine emission standards in Pakistan just because the government doesn't ask for it. As I have mentioned earlier, PakSuzuki is providing the same engine as abroad and that engine complies with euro6 standards. If Pakistan has only euro2 requirement, that doesn't make all engines offered here only compliant to euro2 and not to the higher standards. Regarding changing cars to suit the environment goes only to small level changes. It does not mean that they will change the engine in any major way, which can introduce unseen issues in the field.
By the way, I have provided the source of my information. It would be great if you could also provide your source to the claim you are putting forward so vehemently. And "because I said so" is not a valid source. 
P.S. I am an engineer myself, and my whole family is working with the auto industry in Pakistan and abroad, for the past few decades.
