Happy 40th Birthday, Earth Day!

As adventurers united in a passion for exploring the far recesses of our globe, we know how crucial it is to protect the natural environments we treasure. Most of us pay closer attention to treading lightly upon our precious planet when Earth Day circles around. Yet every time we leave home, we can care for the Earth by incorporating some simple practices into the way we travel. They take little effort but collectively can make a big impact on the environment — not just for Earth Day, but every day.

1. START BEFORE YOU GO

Unplug your electronic appliances when you leave home for an extended time, especially those with digital or LCD displays such as TVs or microwaves — these suck a lot of power whether they are switched on or not. The Department of Energy estimates that so-called “vampire” or “phantom” energy waste accounts for 5 percent of total electronic energy consumption in the United States. You should also make sure your thermostat is turned down or off, and reduce the setting on your water heater.

2. BOOK A NON-STOP FLIGHT WHEREVER POSSIBLE

Planes use the greatest amount of fuel during takeoffs and landings, so choosing a non-stop flight can help reduce the amount of carbon your trip adds to the atmosphere. There are benefits for you, too: By avoiding transfers, you’ll get to your destination faster and you’re less likely to lose luggage.

3. PACK LIGHT

Not only will you save money on checked baggage fees, but you’ll burn less CO2 when you fly if you leave the extra outfits and sundries at home. The heavier the plane’s load, the more fuel it requires to take off and reach its destination.

4. TAKE YOUR WATER BOTTLE

Stay hydrated on your flight and don’t waste multiple rounds of plastic cups by bringing your own H2O along. Keep it with you as you travel to avoid buying costly and wasteful bottled water.

TRANSPORT

“Carpool” by taking a shuttle from the airport to your destination, rather than a taxi. Ride the bus or train instead of renting a car, if you can. And walk as much as possible — it can be the fastest way to get around in big cities like New York and London.

6. RENT A FUEL-EFFICIENT ‘GREEN’ CAR

If you do need to rent a car, choose a fuel-thrifty compact or a hybrid, which are available in increasing numbers through many major rental companies. You can also choose to offset your rental car’s CO2 output by opting to pay a small fee: For just $1.25 per rental, Alamo, Enterprise and National pay TerraPass to offset the average rental’s carbon emissions.

7. STAY AT A ‘GREEN’ HOTEL

More and more hotels are cleaning up their eco-acts. It’s easy to find those that embrace environmentally-conscious practices on a variety of websites. To get you started, Travelzoo has published a list of LEED-certified properties (the U.S. Green Building Council’s Leadership in Energy and Environmental Design) in honor of Earth Day’s 40th anniversary. LEED evaluates hotels for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality to ensure a whole-building approach to sustainability. Worried that an eco-friendly hotel will cost you a lot of “green”? Travelzoo’s list deliberately includes many moderately priced properties.

8. TURN THE LIGHTS OFF

Shouldn’t this be a no-brainer? You do it at home, so be just as conscious when you’re traveling. Even though you’re not paying the hotel’s electric bill, you’re still adding to your carbon footprint. Ditto for not leaving the heat or AC on when you go out, or wasting water when you shower.

9. DON’T BUY SOUVENIRS MADE FROM ANIMAL PRODUCTS

It’s sometimes difficult to tell whether that memento for sale in a shop or market may have come from an endangered species: handbags made from reptile skins, jewelry from marine turtle shells or carvings from elephant ivory. The smartest approach is simply not to buy objects made from exotic wildlife. Many animals are threatened by illegal trade, according to the International Fund for Animal Welfare.

10. GIVE BACK WHEN YOU GO

Consider devoting a future trip to “voluntourism,” where you take a vacation and serve the planet at the same time. Drink in incredible scenery while you build and maintain trails with The American Hiking Society. Band penguins in Antarctica or map water supplies in drought-stricken Kenya with the Earthwatch Institute. Focus on helping people in need through GlobeAware’s Adventures in Service. The opportunities are truly unlimited! Or, explore possibilities to tack on a few days of service in conjunction with your next trip with Natural Habitat Adventures — anywhere we go, there are certain to be volunteer opportunities available somewhere in the vicinity.
