Calculate your carbon footprint

The average Canadian consumer generates 5,000 kg of carbon dioxide annually. To find out roughly how you measure up, pull out your utility bills, grab a calculator, and follow these simple instructions. BY ALEXANDRA SHIMO

A ELECTRICITY AT HOME

Multiply the number of kilowatt hours you consume annually (usually found on your electricity bill) by

i) 0.84 if you live in Alberta, Saskatchewan, or Nova Scotia

ii) 0.42 if you live in Ontario, New Brunswick, N.W.T., Nunavut or P.E.I.

iii) 0.034 if you live in any other province or territory

B. HEATING AT HOME

Multiply the cost of your monthly fuel bill by 50

C. AUTO MILEAGE

Multiply the number of kilometres you travel annually by

i) 0.1, If you drive a small car or a hybrid

ii) 0.17, if you drive a medium-sized car

iii) 0.36, if you drive a large car, SUV or sports car

D. FLIGHTS

i) Multiply the number of return short-haul flights (less than four hours) you take in a year by 400

ii) Multiply the number of return long-haul flights (more than four hours) you take in a year by 1,000

E. GARBAGE

Everyone creates garbage. Add 300.

F. RECYCLING

i) Do you recycle newspaper? If not, add 83.

ii) Do you recycle aluminum and tin cans? If not, add 75.

CALCULATOR

Add A + B + C + D + E + F

Note: This calculation is for a one-person household. If you live with more than one person, then divide the total of A + B + C by the number of people living in your household.

RESULTS

(in kilograms of carbon dioxide per year)

Less than 3,000: excellent

3,000 to 4,000: good

4,000-6,000: average

More than 6,000: poor
