Is350 Emission Question

[amx]

I`m new here, and I am planning to buy a IS350.

I have searched, but I found nothing information about emission/exhaustgas.

Need more information about CO (Carbon Monoxide),HC (Hydrocarbons) and NOx (Nitroen Oxides).

I found information for IS250 (Co2=214 g/km) and IS220d (Co2=168 g/km) but nothing for IS350.

Doe anyone know where I can find this information for IS350 ?

I need this for calculate tax.

Any information is appreciated and useful.

Thanks for your time
