Challenge
Hop on your bike for one day of fresh-air commuting to work or school.
Individual Result
By not driving just one day, you will reduce your CO2 emissions by 26 lbs and save about $3.
Rally Impact
2749 people have reduced CO2 emissions by 35.74 tons by completing this challenge so far. That's equal to turning off the electricity of 35 homes for about 1 month!
Challenge Details
- In Japan, 15% of commuters bicycle to work. In the Netherlands, 50% of commuters bicycle to work. Less than 2% of U.S. commuters bicycle to work.
- The average person loses 13 pounds of body weight during their first year of commuting by bike.
- The average car owner spends about $10,000 each year on car-related expenses. A bike’s upkeep is almost nothing.
Do you really need encouragement to ride a bike? Isn’t that something any child knows is one of life’s simple joys? Well, as obvious as that may be, that’s what we’re doing in this Challenge. We’re asking you to park your car and ride a bike to work or school. So, go on. Tell the world that you’re doing it to reduce your carbon footprint. Tell your friends that you’re doing it to get healthy. We won’t tell anyone you’re doing it for fun.
This challenge was originally inspired by a suggestion from Alexiz. Several other rallyers have posted similar ideas that have been very popular in the workshop. Check-out the high scoring ideas from: soxrox 101, XCrunner, Alim, and H2O Marc.
The Carbon Connection
Each gallon of gasoline burned in an average car’s engine blows 19.4 pounds of CO2 out the exhaust and directly into Earth’s atmosphere. The less we drive, the less gasoline we burn. When you ride a bicycle or walk someplace instead of driving your car, you are keeping unnecessary greenhouse gases out of the atmosphere.
Driving also costs money. At current national average gasoline prices ($2.45 per gallon of regular), choosing your bike over your car saves you about $3 per day, not including tolls, parking, and so on. With gas prices going up again, your savings will undoubtedly increase.
Getting It Done
You don’t need to overthink this one; just decide to give it a try. Start by making sure your bike is in good working condition. Check your bike helmet for a good fit. Plan a route that avoids heavy traffic, bad roads, and killer hills without adding too much distance to the trip. And allow yourself time to make the ride at your own pace.
Here are a few other things to think about when considering this Challenge:
- Bike riding is a great way to get low-impact, aerobic exercise. For example, a 150-pound bike rider will burn around 430 calories for every 10 miles he rides.
- Bike safe! You don’t have to wear spandex pants with a padded butt, but you do need to wear a properly-fitted bike helmet. Be smart about the hazards of the road, such as opening car doors, potholes, wet roads, and so on.
- If you find you’re ready to ditch your car, you might want to follow the suggestions from our friends at Izzit Green and look into some cool commuting bikes.
- You may be able to get a $20 per month benefit from your employer for using your bicycle to commute to and from work. Read more about the Bicycle Commuter Act at Treehugger and talk to your employer about having your company participate.

Let’s start with the known or estimated numbers:
- This Challenge gives you credit for the carbon savings realized by keeping your car off the road for one day of average commuting to work or school. According to a 2005 ABC News poll, the average daily commute is 16 miles each way to school or work. That’s 32 roundtrip commuting miles driven each day. source
- The average American car used in commuting to work or school gets 23.9 miles per gallon of gasoline. source
- Each gallon of gasoline burned by an automobile engine leads to the release of 19.4 pounds of CO2 into the atmosphere. source
Now put all that together to get the following equation:

Riding your bike shows your commitment to preventing climate change. The more of us there are, the easier it will be for our communities to support new bike path projects or for businesses to support biking as a commuting choice for customers and employees. So, grab your bike helmet and hit the road, Rallyers.
