Ultra Low Emission Vehicle (ULEV)
Last Sunday morning, I was up in the air flying with my paragliding buddies. Yes, paragliding, the sport where you run off the side of a mountain and then float around on the movement of air with the belief that you will somehow negotiate with the wind gods. Today, we were flying in an area around Harrison Lake, British Columbia, a spectacular valley region about 90 km from Vancouver. This location combined with ideal conditions had me thinking about vehicle emissions …
With the sun and light wind form the south we were able to fly up to between 1,000 and 1,500 m. This just happens to be an elevation where low level smog and generally dirty air collects, particularly on a warm sunny day. At 1,200 m, and flying in a valley downwind of Vancouver, I saw it clearly: that oozing yellowish brown concoction found in and around most large urban centres in Canada.
And then it struck me: does anyone outside of the automotive vehicle emission legislative and regulatory system have any idea what ULEV is? What it means and its significance? And yet, along with ULEV, there is a long list of vehicle emission classifications: the PZEV, LEV II and ZEV, to name a few. Quite confusing, isn’t it?
ULEV is an Ultra Low Emission Vehicle. In very simple terms, a ULEV vehicle produces 50% fewer emissions than the average for new cars released in that model year. And yes, the new 2009 Volkswagen TDI Clean Diesel is a ULEV. This, of course, is a very good thing for all air breathing (and flying) beings. However, it seems to me complicated, confusing and less than helpful to the Canadian new car consumer.
Today, as I floated on my “wing” to the LZ (landing zone – my life is full of acronyms!), I wondered if it might be easier for folks purchasing a new vehicle and concerned about air quality to ask questions about the distance a car will go on a litre of fuel as a measure of how clean it can be.
Most of us understand:
- the farther we go on a litre of fuel, the fewer emissions our vehicle will produce
- a litre of gasoline/diesel produces a fixed amount of carbon (CO2) per litre burned. New technology emission filters do not scrub carbon, which I talked about in a carbon post on Sept. 26, but it is being worked on! Simply stated, the carbon from an internal combustion engine is purely a function of fossil fuel and air combustion
- that government regulation of auto manufacturers continues to improve emission profiles of all vehicles (ULEV, etc.)
So rather than confuse the issue with complicated acronyms, why not make it really simple? The lower the number of L/100 km (fuel required to travel 100 kilometres), the lower the emissions and of course the lower the cost of operating a vehicle. I think if we continue to get caught up arguing and posturing over which 5 L/100 km vehicle is better than the other (and there are not that many of them) we miss what is important.
I know this is not a perfect answer for a comparative analysis of vehicle emission profiles. However, if more of us based our purchasing decisions on going farther with less, I’m confident the air we fly in up in the valley here in the lower mainland will improve in time and that, my friends, would be a good thing for all of us. By the way, to lower our vehicle emissions further, we drove the 180 km trip to the gliding site on Volkswagen approved biodiesel!

Consumers continue to have questions about what is truly ‘responsible’ when considering the impact of material purchases. I think people, even in this economic climate, remain curious about the solutions and available options and are interested in what might be the ‘right’ direction to pursue. However, the myriad green certification, labeling and brand rhetoric can confuse and frustrate an interested party. Cars are certainly not immune to this challenge.
I agree with you about pollution. We have California to thank for driving the dialogue and direction of the established rating systems while credit for the regulation of tailpipe emissions goes to the Nixon administration of the 70’s which certainly kicked off improved health for millions in urban air sheds.
Today we are at the point where we are seeing incredibly small emission numbers in a broad range of vehicles. I am not defending the industry here, only suggesting that the overall emission strategy for the past 30 years has had distinct smog as opposed to carbon focus and they have done a decent job of lowering these impacts significantly however the direction today appears to be climate focused.

I may have confused readers with an assumption, emissions = pollution, when in fact emissions are both smog AND greenhouse gases (GHG) which in fossil fuels is primarily carbon, CO2 (for more detail check this earlier post).

The GHG rating, measured as grams per kilometer – g/km, is directly proportional to the consumption rating, the CAFE or fuel economy number. This of course assumes you are burning fossil fuel; adding a biofuel blend could further lower the emission numbers. When a fossil fuel is burned carbon is released at a fixed rate per unit of liquid energy. Which is to say, the less fuel we burn over a set distance the lower the carbon and other GHG’s emitted.

Like you and me, consumers walking into a dealership even today have an interest in the personal impact of a product or what is commonly referred to as footprint. They are interested in things like efficiency, durability, the recyclability of a vehicle AND the business practices of the global brand. What are the Corporate Sustainability actions of the manufacturer on waste, water and energy – climate change etc? What actions has the branded dealership business taken to improve the footprint of the business?
On this front many initiatives are underway beyond the manufactured product. I know that Subaru is working to increase the number of zero waste assembly plants. Porsche heats most of its facilities with thermal recovery technology while last year in Truro, Nova Scotia, the new VW store opened with a Geo-Thermal heating and cooling unit reducing the carbon footprint of the facility to near zero.
Environmental impact questions are becoming part of purchasing decisions across all industry. The conscious, aware, interested consumer is still with us and most likely will continue to grow as a market segment. Fortunately for everyone most automobile manufacturers are responding to the point where consumers now have a selection of advanced, more responsible and cleaner transportation options from corporations who have begun to shift business practices towards a more sustainable direction; A good thing for all of us.
We appreciate the interest.
Thanks for engaging.

That is stupid
The fuel consumption of a car is not directly related to its polluting emissions.
If pollution matters to you, a Subaru AT-PZEV is way better than a Volkswagen TDI, even if its fuel consumption is a lot higher.
