Green behavior around the globe
Preserving the environment seems like a topic with universal interest. But having an interest doesn’t always mean we’re willing to change our behaviors. If you’ve ever wondered about someone else’s attitudes toward sustainability, you should check out National Geographic’s Greendex.

A lift in efficiency for cat owners
Cat litter is heavy. Heavy as in lifting-a-small-child-into-the-cart heavy. Just ask anyone who’s hoisted those boxes or plastic tubs into a shopping cart, and that person will tell you that lifting litter is as good as lifting weights.
The clay litter is effective but its weight has distinct disadvantages. Continue reading

Feeding the nine billion
How will we protect our land and water resources, and simultaneously, feed the world? By 2050, we expect the world’s population to increase by nearly two billion people, to nine billion.
How do we ensure that our planet is able to feed the nine billion, especially when hunger is already so prevalent? Continue reading

A simple way to save electricity
To save energy and money, turning off lights is an obvious way to start. But did you know that switching up your lighting can save you even more? According to the Alliance to Save Energy, lighting can account for 12 percent of a home’s energy use. To find out how much you may save – as well as what’s in a lumen – check out their cheat sheet below.

Drive down your gas costs this Memorial Day weekend
Did you know that your GPS device and certain smartphone apps can give you real-time gas mileage tips, and point you to the cheapest nearby gas station? How about the fact that every extra pound of luggage decreases your fuel economy, as does driving faster than 60 miles per hour? Learn these gas-saving secrets and more from this video, as well as six other videos on fuel efficiency from the Alliance to Save Energy.
Here are a few more tips:
- Avoid aggressive driving. Speeding, rapid acceleration and rapid braking can lower gas mileage by 33% at highway speeds and by 5% around town, according to the Alliance to Save Energy.
- Avoid excessive idling. Idling can waste a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner use. But it only takes a few seconds’ worth of fuel to restart your engine, according to the U.S. Department of Energy.
- Combine errands into one trip. Several short trips taken from a cold start can use twice as much fuel as a multipurpose trip covering the same distance when the engine is warm.
- Beat the traffic. When possible, drive during off-peak hours to avoid stop-and-go or bumper-to-bumper traffic conditions, thereby reducing gas costs, time and stress.
- Keep tires inflated. Properly inflated tires can improve mileage by up to 3.3%. Conversely, under-inflated tires can lower gas mileage by 0.3% for every 1 psi drop in pressure in all four tires. In addition, proper inflation improves tire longevity and driving safety. Find the proper tire pressure for your vehicle on a sticker on the driver’s side door jamb, in the glove box, and/or in your owner’s manual.
This chart shows how much you can save from each fuel efficiency tip. These suggestions can also improve your driving, increase the life of your tires, and help you beat traffic.

FUEL EFFICIENCY TIPS |
MPG INCREASE | ANNUAL SAVINGS |
| Smart Driving | ||
| Avoid aggressive driving | up to 33% | $981 |
| Drive safe (highway) | up to 10% | $218 |
| Lose 100 pounds from trunk | up to 2% | $40 |
| Car Maintenance | ||
| Tune up vehicle | up to 4% | $82 |
| Fix oxygen sensor | up to 40% | $1,308 |
| Keep tires inflated | up to 3% | $61 |
| Use recommended oil | up to 2% | $40 |
| Fuel Efficient Car | Switching from 20 MPG to 30 MPG vehicle |
$930 in fuel costs* |
| The MPG increases and dollar savings are estimated for each tip based on data from 2011 Transportation Energy Data Book and U.S. Energy Information Administration (EIA) assuming vehicle fuel economy as 21.2MPG, average national gas price as $3.69/gallon, and annual 11,300 miles of travel. Actual results depend on how well you already follow these practices, whether you use more than one tip at a time, and other factors. *Sources: Alliance to Save Energy research and Department of Energy |

Changes in plastic packaging help put a lid on GHGs
The uses for plastic are many. And often, so are the questions about recycling it.
There are seven different codes that indicate the resin content of post-consumer plastics, which determines whether it is collected for recycling in a particular locality.
Last year, a Walmart Canada team identified not only a way to make the process easier for everyone – but also a way to reduce the 5.85 billion pounds of plastic being added to landfills across North America annually, according to the National Association for PET Container Resources.

Drawing from new ideas
This week, nearly 200 packaging suppliers are showing their latest innovations at the 7th Annual Walmart and Sam’s Club Sustainable Packaging Exposition. Here is an example of how small changes, such as the shape of a bottle or box, can translate into a bigger environmental impact.
