New dreamliner touches down in Perth, bringing hope of tourism boost

  New dreamliner touches down in Perth, bringing hope of tourism boost Singapore Airlines is the first to fly the newest dreamliner and Perth is the second destination in the world, after Osaka, to welcome its arrival. The plane gives them capacity to offer 38,000 extra seats on the route each year.Singapore is currently the third largest international tourism market for WA by visitor numbers, and fourth largest by visitor spend.About 102,000 Singaporeans visited WA in 2017 and spent $220 million.It comes as a much needed boost for WA’s waning international tourism numbers. require(["inlineoutstreamAd", "c.

Maldives© AFPRelaxNews Maldives Global tourism is responsible for about eight percent of global greenhouse emissions -- four times more than previously believed, according to the results of a new study.

The findings, published in the journal Nature Climate Change, show that the environmental impact of globetrotting travellers -- particularly affluent jetsetters -- has been significantly underestimated.

Unlike other studies which quantify the carbon footprint of travel by looking mostly at air travel and transport, a team of researchers from Australia and Taiwan took a more comprehensive approach by considering the "life cycle" of a tourist, expanding the criteria to food, shopping and accommodations.

Scientists reveal the most effective supplements and foods to ease the pain of arthritis sufferers (and it's good news if you take fish oil and eat kale)

  Scientists reveal the most effective supplements and foods to ease the pain of arthritis sufferers (and it's good news if you take fish oil and eat kale) Researchers from the University of Surrey found just one-and-a-half standard fish-oil supplements a day significantly reduces patients' crippling discomfort.After analysing more than 60 studies, the researchers discovered just one-and-a-half fish-oil supplements, or one gram, a day significantly reduces crippling discomfort in OA sufferers by easing inflammation.

The study , which looks at the spending habits of travelers in 160 countries, shows that the impact of tourism on global emissions could be four times larger than However, the results may still be underestimating the total carbon footprint of tourism , another scientist told Carbon Brief, because

After looking at tourism-related activities among 160 countries between 2009 and 2013, researchers estimated that tourism's global carbon footprint increased from 3.9 to 4.5 GtCo2e (gigatonnes of equivalent carbon dioxide) -- or four times more than previous estimates.

Researchers also showed that wealthier travellers -- who are more likely to travel by air and consume more goods and services -- leave behind bigger carbon footprints than lower-income travellers.

Topping the carbon footprint ranking is the US, followed by China, Germany, India and Mexico, and mostly from domestic travel.

At the per-capita level, small island destinations like the Maldives, Mauritius, Cyprus and the Seychelles feature some of the highest destination-based footprints, with international tourism representing between 30 and 80 percent of national emissions -- a reality that presents a significant dilemma, authors note.

Change text size: A a a. Carbon Footprint of Global Tourism Rising. A new study conducted by researchers at the University of Sydney shows that global tourism , a trillion-dollar industry, contributes significantly to greenhouse gas emissions and its carbon footprint is expanding rapidly.

Soil erosion that occurs in rainy seasons leads to a significant amount of carbon being released into the atmosphere, a new study shows. Global tourism carbon footprint quantified in world first.

"In particular, island destinations face an enormous additional carbon burden as they host a significant number of inbound tourists. These islands benefit substantially from the incomes from tourists, so their governments face a challenge of how to impose national mitigation strategies without reducing tourism income," reads an excerpt.

The study also found that Canadian, Swiss, Dutch, Danish and Norwegian travellers leave a bigger carbon footprint in the countries they visit, compared to visitors to their own countries.

With global travel projected to grow four percent beyond 2025, researchers emphasize the need to monitor and mitigate tourism-related carbon emissions, perhaps with carbon taxes or carbon trading schemes.
