Don't forget to track your green commute this week at commuterchallenge.ca.

If you work for CPL, or other participating workplaces, your workplace is already registered and you can register as an individual. The tracking is really straightforward this year.

If you provide your Airmiles number, you are eligible to win 500 Airmiles!

Hint: An easy way to calculate your kilometerage is to use Google maps "get directions" tool and enter your start and end points. Your one-way kms are displayed. Double it when entering your Commuter Challenge information.
