Walter, in his article You, and me and GHG, states:
According to BC’s Ministry of the Environment, transportation is the single largest source of green house gas in the province, accounting for 42% of the total emissions.
The 42% figure is implicitly referencing an 6-year old source of data. The latest inventory figures, which is for 2004, show a 40% total, or 27,000 tonnes of CO2 equivalent.
We have the science and technology right now to reduce our green house gas emissions by up to 30%. How do we do it? By making smarter vehicle choices.
Unfortunately, it is not that easy. Let’s say you wanted to target 30% of the GHG budget. This is a reduction of 8,100 tonnes.
Out of the 27,000 tonnes, we have the following that are relatively “untouchable” for relatively obvious economic necessity arguments:
Domestic Aviation, 1,500 tonnes
Heavy-Duty gasoline/diesel vehicles, 5575 tonnes
Railways, 400 tonnes
Domestic Marine, 2,700 tonnes
Offroad, Pipelines and “Others”, 5,500 tonnes
This leaves about 11,500 tonnes, which consists mainly of light duty gasoline vehicles (5,130 tonnes) and trucks (5,790). We need to excise about 8,100 tonnes out of this. Even if you gave everybody in the province a hybrid vehicle, the most you could get that figure down to is 7,500 tonnes between the both of them, for a savings of about 13% of the transportation GHG budget.
This clearly cannot happen. The only way that you can achieve a 30% cut in the transportation GHG budget is by reducing obviously commercial forms of freight (heavy duty diesel vehicles) in conjunction with a reduction of actual trips by people and more efficient vehicles.
I can see a decrease of 10% of the transportation GHG budget happening with significant capital expenditures but 30% is just not going to happen, especially in light of BC’s increasing population and trade route activity.
Yes I know that hybrids currently make up less than one per cent of total new car market right now, but sales are growing exponentially. We can all do our part in reducing green house gas emissions by simply buying a more fuel efficient vehicle.
Let’s take an example, the Toyota Camry:
Toyota Camry Hybrid – $32,000 base model MSRP. Add GST/PST: $36,160. Subtract $1000 (federal) and $2000 (provincial) fuel efficiency / hybrid incentives. Total price $33,160. Consumption: 5.7L/100km or 50mpg (city or highway).
Camry LE – $25,900 base model MSRP. Add GST/PST: $29,267. Consumption: 9.5L/100km (30mpg) city, 6.5L/100km (46mpg) highway, 8.0L/100km (35mpg) combined.
Cost of gas is about $1/litre, so that’s still a differential of about 3900 litres of gas. This is enough to get you 68,000km on a hybrid or 49,000km on a standard model.
The economics are still not there in terms of a person buying a new vehicle – the pure gas engine is still the better option when you factor in cost of capital. The incentives, however, have made it a closer decision.
Of course, when looking at a hybrid vehicle vs. something like a Toyota Yaris, the comparison doesn’t even come close:
Yaris, automatic transmission, and we’ll throw in all the options and goodies (the “Enhanced convenience package”) for $18,720 MSRP. After GST/PST that’s $21,153. The car also qualifies for a $1,000 federal rebate due to being good on fuel economy so the purchase price is $20,153. Consumption: 7.0L/100km (40 mpg) city, 5.6L/100km (50 mpg) highway, 6.4L/100km (45mpg) combined.
This difference amounts to 13,000 litres of gasoline and nobody is going to drive their Yaris or Hybrid vehicle for the distance required to burn up that much fuel. If people were truly interested in being environmentally friendly with their car, they would pick a Yaris instead of a hybrid vehicle.
The economics of replacing an existing and functional vehicle are even worse – gas is nowhere near the price where it would be worth junking a functional car for fuel economy purposes.
Sorry Walter, but the best thing I can do for greenhouse gas emissions right now is to keep my existing (six cylinder) vehicle in good shape and keep driving it. Mind you, if I was given an incentive of 5 thousand bucks to get a smaller vehicle I would snap on that offer very quickly. But as a taxpayer, I wouldn’t want to be subsidizing such activity as I don’t think the cost-benefit analysis would make the expenditure a net positive.
