Mark writes: In our posting about transportation in September, I promised to work on the efficiency of my driving.

I started by taking an online course sponsored by Natural Resources Canada. It’s designed to teach drivers some simple techniques to lower fuel consumption. You can sign up for it here.

The course has 3 main topics: Driving Behaviour (driver efficiency), Trip Planning (to drive a shorter distance by combining trips, etc), and Improving Your Vehicle’s Performance.

Here are a couple of interesting statistics, and a few of the pointers I got from the course.

Amazingly, there is one car for every two people in Canada. About 18 million light vehicles drive a whopping 300 billion Km every year. And the average vehicle puts about 4 tones of Co2 into the air each year. If we could drive less and more efficiently, that would make a big difference.

Here’s how we can improve:

Accelerate gently. Imagine you have an egg on the gas pedal. In the city, 50% of fuel is burned just getting up to speed from a stop, so this is the most important thing you can do. It should take five seconds to get to 20Km/hr from a complete stop.

Maintain a steady speed and anticipate traffic, so you don’t have to slow and accelerate so much. If you watch ahead, you can coast to slow down, which also saves fuel.

Avoid high speeds. Cars are typically most efficient from 50-80Km/hr. It can take 20% more fuel to drive 120Km/hr compared to 100Km/hr.

The course goes through much more detail on how to plan errands to drive shorter distances, and how to make your car run more efficiently (by reducing weight, getting a tune-up, and keeping the tires properly inflated).

Through practicing more awareness of my own driving habits and being more aware of other traffic, I became less hurried and much calmer as I drove. Somehow this awareness had made city driving at lot less… well, annoying!

And so far, I have improved my fuel consumption for city driving by about 20%.


September: Transportation

Transportation is a little simpler than other topics we’ve tackled. Basically, bike, walking and transit are very good, while flying is very very bad.

Trains are good but we don’t have them here. We have freight trains, and a tourist run to Vancouver that costs more than flying, but nothing else.

Flying is one of the worst ways to spend our carbon-dollar. First, it takes a lot of fuel to fly a plane. Second, “the fuel is burned at an altitude where it has, as a best estimate, nearly twice the climate change impact that it would have had at ground level.” (Mike Berners-Lee, How Bad Are Bananas, p. 60, Greystone Books, 2011).

Any alternative to flying is better. Of course, sometimes that’s just not viable, especially in a huge country like Canada, or for international travel. We’ll be checking out carbon offsets the next time we fly, our personal carbon tax on flying, until there’s an actual carbon tax on flying.

We do walk, use transit and bike. We could/should/would do more. We’ll work on that.

We have two cars, which in itself is a big carbon hit, before considering any mileage. We’re not quite ready to shift back to one (we were a one-car family for many years). Our mileage has always been low, although that’s changing a little now. We head into the mountains once a week, and our parents live on the edges of Calgary, far from our central location, and far from each other. It looks like our mileage will be about 30% higher this year.

Our 2007 Honda Fit and 2010 Mazda 5 rate “Superior” on, the top rating, and were both best in class. search page. The Fit is rated at 7.3 Litres/100Km in the city, and 5.8 on the highway. Our measured mileage on the Fit was between 7.0 and 7.9 l/100Km, which is pretty good as we mostly drive in the city. The  Mazda is rated at 10.7 in the city and 8.4 on the highway. We’re not faring as well here; our actual mileage is between 11.5 and 14 l/100Km. The very best conventional cars are at the 7.0 l/100Km mark, so we are doing very well with the Honda. The hybrid Toyota Prius is rated at about 5.4 in the City. Natural Resources Canada’s guide.

Fuel efficiency can be boosted by up to 30% with simple maintenance and some driving changes. These include avoiding aggressive driving, as fast acceleration and deceleration both waste fuel. Watch highway speeding, as fuel consumption is up to 20% higher over 90 km/h, depending on the vehicle. Avoid any idling more than 30 seconds, except to clear the windshield in cold weather. Avoid driving in heavy traffic as much as possible. This both speeds up the trip, and doesn’t slow down other people, so there’s a double carbon gain. Make sure tires are inflated correctly, and vehicles well maintained. Plan trips for efficiency. For more details, there’s a good list at

We’ve decided to try to improve the efficiency of the Mazda. For a month or so, it’ll be used only for city driving, to make the test clean, and driven only by Mark, who will try to develop more efficient driving skills. We’ve read this can improve efficiency from 10-30%. Mark will take a Natural Resources Canada on-line course on efficient driving.

Our vehicles are 6 and 9 years old. We typically replace cars around 12 years, when they start to become less reliable. That’ll be when we take a close look at alternatives.

At the moment, a fully electric car sounds brilliant for city driving, but we wouldn’t take it into the mountains. Calgary to Jasper is 412 km, and we drive it in one day. We can’t get there on a single charge. Someday there might be enough charging stations. Today is not that day. At the moment there’s only one gas station between Lake Louise and Jasper, a 232 km run. We won’t drive into the Canadian Rockies and risk running out of fuel. That’s just not safe.

We could have an electric car for city driving and a gasoline car for road trips, but that seems foolish. A hybrid might make more sense for us. We’ll keep watching the rapid and exciting developments for electric cars, improved batteries, solar roofs on electric cars, and dropping prices, and make the move when it’s time to replace a vehicle. Here’s a great article on the shifting cost of clean cars. NPR: It may not cost you more to drive home in a lower emission car.

Perhaps the most important thing we can do is to advocate for a healthy carbon future, including voting for those who support mass transit.

In October we’ll be digging in to food.


Fueled By Hope

The day the United Nations COP21 climate change summit accord was signed in Paris on December 13, 2015, committing us all to a lower carbon future, I was thrilled, especially by the increased discussion of the need to get to zero carbon. I linked to an article about it on Facebook, and wrote, “Now we need to get to work.”

Then I started thinking about it. Clearly there’s a ton of work for governments and industry. What can we do as individuals, in addition to lobbying, donating and voting for those who are working to protect our environment? I don’t even know what zero carbon means. What will it look like, at my house?

I tend to do this – learn something new in theory and then need to figure out what it looks like on the ground. In my house, in my garden. So I hatched a plan and talked my husband into joining in. This blog is our first step.

Through 2016, we are going to work on this question: How do we get to zero carbon, at our house?

I wrote to the Suzuki Foundation for advice. This was their reply:

Thank you for your interest in carbon neutrality. The process is actually fairly simple:
– Measure the emissions from your household
– Reduce emissions where possible at your household
– Purchase emissions reductions made elsewhere (carbon offsets) to balance the remaining emissions you were not able to reduce.

I’m not convinced it’ll be simple. Mark says it’s kind of like saying you play the flute by blowing in one end and moving your fingers up and down. But we’re going to leap in and learn to play.

Our plan is to tackle one topic a month, researching and making the easy changes.  We’ll research the big stuff too, like electric cars and solar panels, so when the time is right we’ll be able to move quickly. That’s not likely to be this year.

January will be about finding out our current carbon footprint, and what it would cost to buy carbon offsets for that amount. This will define where we are and set a price on the problem. We’re also hoping to book an energy assessment of our house, so we’ll know what we need to work on most.

We’ll report on our progress at the end of the month, and set goals for the next month.
