Calculate your carbon footprint
Here are two websites that will help you to calculate your carbon footprint.
Earth Lab offers a basic calculation. A simple profile is built as you answer a few questions. This determines your carbon footprint rating. I was a bit surprised to see that I still rate a bit above the Canadian average. This may be because there are several things that we do at home that there seemed to be no questions for (ie. our own vegetable garden, dual-flush toilets, general low water consumption, purchase of fewer packaged goods).
Eco Action is a government of Canada environment website that offers a variety of carbon calculators. Here you can calculate your fuel, water and energy consumption at home and as an organization. There are also several very useful and educational tools on this site that will help you to reduce your carbon footprint. I was impressed with the amount of information available through the Eco Action tools and calculators.
