>Well what do people think about the emmisions testing?

A good concept but not implemented all that well. Ebco-Hamilton has
obtained a remarkable contract that obliges the province to move
1 million cars through the test programme every year. 

>(I drive a '91 car, so NYAH! no testing for me).

My 1981 car passed with very large margins. 97% less HC than the max. 
allowed. Absolutely no (0%) CO emissions, and over 50% less NOx than 
allowable.

Yes, and the stories of blown engines shown on TV recently is worrying.

There is also the conditional pass, which you get if you fail the second
time, BUT paid $200 for repairs at an Air Care approved service station.
This is equivalent to a tax, but at least the car will be somewhat
cleaner.

Not more taxes!! Anyway, it wouldn't clean the car. The current test
system obliges the owner to maintain their car and repair it if it
fails to maintain required standards.

I don't think so, I can't afford a newer car. I can, however, ensure that
my car is running properly.

I think it's fine. My car doesn't have a 3-way catalytic converter, but
the older CO-HC version. It doesn't have fuel injection, engine
management systems or other 90's gadgets. Fitting such units on older
cars would be impossible. 

As far as older cars meeting the latest specs is concerned, how would you 
like it if you were forced to trash a car (you couldn't sell it, who would 
buy it?) every few years because it didn't meet the latest emission 
requirements? Your car will pass the 1991 requirements. But will it pass
the 1992 requirements? Or 1993? Can you buy a new car every year? I can't.

One immediate solution which could reduce emissions in all cars is 
alternative fuels. MTBE and ethanol blends are claimed to reduce emissions 
by 20%. Both are available now.

The government's stats suggested that cars were the greatest offenders.

Most airports have landing fees. I don't think Vancouver is different.

>Does anyone know the gases they test for?

Do you mean Air Care? They test for HC, CO and NOx at idling and under
load. CO2 isn't measured. Diesels are tested for particulates. 

CO2 isn't considered harmless at the moment (global warming).

How about gas lawn mowers (real polluters!) motorcycles, power boats, mills
etc. etc..
