We ran across a fun website recently that helps kids track the carbon footprint of their family. It's easy to use and the results are calculated in terms they will understand such as how many trees, water or land your family uses each year. We think it's a fun tool for those who are at least of reading age, heck it was fun for us, click through to see how it works...
The website is well organized and easy to navigate. It's truly aimed at children and is able to keep their attention with simple questions in words and situations they can identify with.
The questions pertain to your family's transportation usage, food consumption, things you use and things you throw away. If your child doesn't know the answer to a question, the program will plug in the national average (for Canada, since that's where the website originated) instead to keep things moving.
We had fun doing it (although we're not sharing our results!) and we know that your kids will as well. Give them something "green" to do at the computer instead of homework or playing games!
