Citing green hotels, coconut oil fuel for airlines and even recyclable golf tees, executives in one of the world’s largest industries say they are urgently trying to shrink tourism’s oversized environmental footprint.

But with global travel projected to keep soaring, and those very leaders still eager to expand their own ventures, some doubt such efforts can significantly lessen global warming and other ecological woes.

“There are no simple solutions,” Anna Pollack, head of a British tourism consultancy, told a two-day conference which ended Wednesday. “Tourism is both a victim of and a contributor to climate change.”

Online you can read the a lot guides about how to reduce global warming. As you can see travel is only a little part of the main causes of global warming.

Below, I list of useful guides. You can use to reduce global warming.

Global warming refers to the Earth’s air and oceans gradually heating up to a point that disrupts balance, a problem that is continually getting worse. It sounds like a problem too massive for any one individual to take on, but it really isn’t. Combining any few of these suggestions can make more of a dramatic effect than most people understand. The goal is to emit less carbon dioxide into the atmospher

The part of Global warming caused by travel, is especially the ecotourism, practiced in remote destination. It’s so because it requires the use of air travel to land is those countries.

Some times ago an airline company used to travel with biofuel.

IN February, on a chilly, clear Sunday morning, Sir Richard Branson, president of Virgin Atlantic, along with the co-sponsors Boeing and GE Aviation, lured more than 200 journalists to a hangar at Heathrow Airport near London to witness what they said was airline history. Over flutes of Champagne and plates of mini-bagels filled with salmon, everyone’s eyes were fixed on a 747 as it took off on the world’s first biofuel demonstration flight.

Never mind that only one of the plane’s engines used biofuel, and that was about 25 percent mixed with standard kerosene jet fuel. It was still significant, given that air travel is the fastest-growing source of global greenhouse gases, and the race to find an alternative to kerosene is now crucial. The biofuel used — a combination of coconut and babassu (a Brazilian tree) oil, which Mr. Branson pretended to drink that day like an island cocktail from a coconut shell — worked in this very small test. But even its developers, Imperium Renewables, are aware it could never become a substitute for what John Plaza, president and chief executive of Imperium, another sponsor, says is the 87 billion gallons of fuel needed each year to fly the world’s airline fleet.

“This is just a first-generation product,” Mr. Plaza said. “But the test was meaningful in that it showed that a biofuel was viable with the infrastructure in a commercial jet.” Imperium created the fuel from oils harvested from existing plantations, but Mr. Plaza said he believed that algae was the fuel of the future. “You would only need the landmass of West Virginia,” he said, “to make enough fuel to replace aviation’s demand for kerosene.”

So I’m not scared about the future, because change is happened. I think that most airlines will become more green so traveling in foreign countries will be less environmental damaging.
