"I'd put my money on the sun and
solar energy.
What a source of power!
I hope we don't have to wait 'til oil and coal run
out before we tackle that." - Thomas Edison
Kyoto Fuel Efficiency Chart (metric)
1 gallon of gasoline produces 20 lbs of CO2
Next time you fill up, set
your odometer to zero. Don’t use the chart yet.
From now on, each time you
fill up, read the odometer, and fill in the distance travelled
(A). Then reset to zero.
Enter the litres purchased
(B). Take the data from the pump or receipt.
You MUST fill your tank to the
max to get a reliable measurement.
For your CO2 emissions (C), multiply
your gallons (B) by 20 lbs
For fuel efficiency in miles
per gallon (D), divide distance (A) by gallons (B)
For your CO2 per mile in pounds
(E), divide 20 lbs by your mpg rate (D)
Canada’s Kyoto commitment to reduce
global greenhouse gases requires us to achieve a 20% reduction
in emissions below today’s level. Driving more efficiently is
one way you can play your part to reduce global warming.
Plan your trips. Plan
to do a number of errands in one trip rather than several
trips. Avoid peak-hour traffic, hard acceleration and heavy
braking - they all waste fuel. Driving smoothly and avoiding
stop-start traffic will save fuel, and up to 30% of CO2.
Avoid short trips by walking
or cycling. It’s good exercise, and it will save you up to a pound of CO2 for every mile not driven.
Service your vehicle regularly. If you keep your vehicle well tuned it will reduce your
greenhouse gas emissions by up to 15%.
If your vehicle is manual - change up and into top gear as soon as possible without
accelerating harder than necessary. Driving in a gear lower
than you need wastes fuel. So does letting the engine labour
in top gear on hills and corners. Automatic transmissions
shift up more smoothly if you ease back slightly on the
accelerator once the vehicle gathers momentum.
Speed kills economy. High
speeds require high fuel consumption. Your vehicle will use up to 25% more fuel at 70 mph than it does at 55 mph. On the open road, drive within the posted speed limits.
Stopping and braking. Resting
your foot on the brake wastes fuel, increases brake wear
and decreases braking efficiency. If you think you will
idle for more than 10 seconds, switch off and restart your
engine later.
Filling up. Filling
past the first click of the fuel nozzle may cause fuel to
spill through the overflow pipe when you accelerate or go
around a corner. A properly fitting fuel cap also saves
fuel by minimising evaporation.
Look after your vehicle's
tyres. Inflate your tires to the highest pressure recommended
by the manufacturer, and make sure they are properly aligned.
This will reduce fuel consumption, extend tyre life and
improve handling.
Use air conditioning sparingly – since it will use 10% more fuel.
Travel light. An extra
100 lbs will increase your emissions by 2%. Anything fixed
to the outside increases wind resistance and emissions.
The Guinness World Record for Vehicle Fuel Efficiency was set by John Gough who averaged 93 mpg (US gallons) from Britain’s Land’s End to John o’Groats in October 2002, driving a Toyota Yaris diesel 1.4-litre D-4D. He averaged 35-40 mph, using sensible driving methods to achieve the greatest efficiency. His tips: accelerate to your desired speed gradually, maintain a constant speed wherever possible, and try not to change gear unnecessarily or use excessive braking or acceleration.
