In the United States, we live in an automobile based culture. Many people don't think twice about driving their vehicle short distances to run errands - a mile here, a mile there. What many people don't realize or choose to ignore is that driving alone is one of the least climate-friendly forms of transportation.

Driving Alone

How bad is driving alone relative to other forms of transportation? According to the Sightline Institute with a single driver, you can expect an average of:

• 1.57 lbs of CO2/Mile in a "Sport Utility Vehicle" (15 MPG)
• 1.10 lbs of CO2/Mile in an "Average car" (21.5 MPG)
• 0.59 lbs of CO2/Mile in an "Economy car" (40 MPG)

Obviously filling your vehicle to capacity helps, just consider this:

• 0.37 lbs of CO2/Mile in an "Average car" (21.5 MPG) when Carpooling with three people

While filling to capacity can help for short errands it isn't always an option. So what can you do?

Riding a Bicycle

Riding a bicycle isn't just good for the environment with a net 0 lbs of CO2/Mile, but it's good for you too. Short errands are just one of many uses you'll find for your bicycle - once you start riding again. While you may miss your trunk space at first a quality bicycle grocery bag, panniers or even a basket can reduce this stress. Which one you choose is up to you based on your own personal needs but for the average grocery hauler I would recommend one the following three products:

• Jandd Grocery Bag Pannier
• REI Grocery BagREI Novara 'Round Town panniers
• Cobbworks Oyster Bucket Panniers

If you expect to be hauling lighter loads then you may be a good candidate for a removable handlebar mounted basket - these can often double as a "reusable shopping bag" too.

How Energy Efficient is a Bicycle?

Did you know calories are actually a unit of measurement for the amount of energy that your body can extract from foods . With many new biofuel technologies available today, many of the foods we eat can also be converted into fuel for our vehicles.

According to World Watch Magazine the average automobile burns 1,860 calories per mile per passenger. How does that compare to the average bicycle? The average bicycle and rider burns 35 calories per mile.

Why are bicycles so much more efficient? The key to the energy efficiency of the bicycle is simple - a bicycle and rider are extremely light compared the average car. In a 2 ton vehicle with a 170 lbs driver the driver is only 4% of the total weight. On a heavier 30 lbs bicycle that same driver will be 85% of the total weight. In a vehicle 96% of the energy used each mile is used moving the vehicle itself - not the drive. On a bicycle only 15% of the energy used moving the bicycle itself.

Bicycles are so efficient in fact that under the right conditions a rider can ride faster then a cheetah. In 2002, Canadian rider Sam Whittingham reached 81 mph using a recumbent bike called the Varna Diablo II. That is 11 mph faster than a cheetah which over short distances can attain a top speed of 70 mph.

It's often said you never forget how to ride a bike so why not take advantage it. Riding a bike is not only one of the most energy efficient modes of transportation, it is also one of the most relatively inexpensive. Do you part to fight global warming by taking your bicycle out for a ride.

Today people feel more comfortable behind the wheel of a car, a van, maybe even a large sport utility vehicle. For many people what they find comfortable is what they teach to their children. These patterns that are passed to the next generation have a negative impact on not only their health but also the health of our planet.

Consider the following example:

• In 1969, about 50% of all students walked or bicycled to school
• In 2008, about 15% of all students walked or bicycled to school

How do we account for the remaining 85%? The remaining 85% of children get to school in the following ways:

• 25% of all students take the school bus
• 60% of all students arrive at school in private automobiles

For most parents the safety of their children is their primary concern. They would rather guarantee the safety of their children by driving them to school instead of letting them walk or bicycle. When safety is the primate concern, the potential exercise their child could have and the amount of CO2 emissions they could reduce simply aren't deciding factors.

What may come as a surprise to many parents is that the Federal Highway Administration has a program designed to specifically address these safety concerns, it's called Safe Routes to Schools.

According to the Federal Highway Administration (FHWA), "This decline in walking and bicycling has had an adverse effect on traffic congestion and air quality around schools, as well as pedestrian and bicycle safety. In addition, a growing body of evidence has shown that children who lead sedentary lifestyles are at risk for a variety of health problems such as obesity, diabetes, and cardiovascular disease. Safety issues are a big concern for parents, who consistently cite traffic danger as a reason why their children are unable to bicycle or walk to school."

The Safe Routes to Schools or SRTS Program started in August 2005 is a Federal-Aid program of the U.S. Department of Transportation's Federal Highway Administration (FHWA). According to the FHWA, the goal of the program is to enable:

• To both enable and encourage children, including those with disabilities, to walk and bicycle to school
• To make bicycling and walking to school a safer and more appealing transportation alternative, thereby encouraging a healthy and active lifestyle from an early age
• To facilitate the planning, development, and implementation of projects and activities that will improve safety and reduce traffic, fuel consumption, and air pollution in the vicinity (approximately 2 miles) of primary and middle schools (Grades K-8).

Under the SRTS Program, each state bears responsibility for its own program. You can find more information on your local Safe Routes to Schools program at:

• http://www.saferoutesinfo.org/contacts/index.cfm

• http://www.saferoutesinfo.org/getting_started/

The Safe Routes to Schools program works. According to Laura Kelley, the new Project Coordinators for the Safe Routes to Schools program in Fairfax, California, she has "observed a significant increase in bikers/walkers in Fairfax, and a decrease in motor traffic, as the Safe Routes program has grown."

Think back to your childhood, can you remember a time when walking and bicycling was part of your everyday life? Isn't that something you'd like to share with your children? The Safe Routes to Schools program let's you do just that and best of all you are promoting the health of your children and the health of the planet with one simple action.
