Finland is the 'most sustainable' country, say expats
India finishes last of 60 countries in environment and sustainability, as ranked by the expats who work there.
- How 'green' is life in your work country?
- That's the question InterNations asked its network of expats.
- The United States ended 30th out of 60 countries.
InterNations, the world's largest expat network, has delivered a global ranking with a twist. For the first time, it's asked its members to rate the environmental and sustainability qualities of their work countries. The best country for a sustainable life abroad: Finland. The worst: India. The U.S. lands exactly in the middle, at #30.
The ranking reflects the combined score for three categories:
- Products and Utilities: How available are sustainable goods and services? How 'green' is the energy supply? What about the local waste management and recycling practices?
- Policies and People: How engaged is the local government in green policies? And how environmentally aware is the public?
- Quality of the Environment: Specifically, of the local environment, air and water.
Nordics on top

The Nordic country scores at or near the top in all categories surveyed, including the quality of the natural environment (say 96 percent of expats in Finland), water and sanitation (96 percent) and air (95 percent).
Swedes lead the world in environmental awareness (84 percent versus just 48 percent globally). Perhaps not surprising, for the homeland of Greta Thunberg. This is reflected by government policy. Sweden currently gets more than 50 percent of its power from renewable sources and wants to go 100% renewable before 2040. "I've been here for over 20 years and I clearly see the benefits of my taxes paid coming back to me and the rest of society," says one American expat.
"The beautiful nature, the clean air and tap water, and the focus on the environment," are what one Ukrainian expat enjoys most about Norway. With 76 percent of expats happy with the availability of green goods and services, Norway's 'weakest' category is still 13 percentage points above the global average.
The first non-Nordic in the global ranking, Austria places in the Top 10 for each category and comes in first for the availability of green goods and services (90 percent).
Swiss nature is the most appreciated in the world (98 percent versus 83 percent on average). Switzerland also gets stellar results for air and water quality and the availability of green energy and green goods and services.
Danes are very much into green causes, as is their government, say 83 percent resp. 84 percent of expats. "Organic food is readily available, and they are good with recycling," observes a South African expat. And they love cycling: 9 out of 10 Danes own a bike.
7. New Zealand
85 percent of expats agree that the New Zealand government takes green issues seriously. In fact, New Zealand plans to use 90 percent electricity from renewables by 2025. The country also scores high on the quality of its natural environment and all other categories – albeit slightly less on the quality of its water and sanitation.
"I enjoy the rising awareness about environmental issues and the alternatives the government and society are developing," says one Colombian expat. Indeed, 80 percent of expats agree the German government is pro-environment (versus 55 percent globally).
The only North American destination in the Top 10, thanks especially to expat appreciation of Canada's natural environment (96 percent), but also the quality of its water and sanitation (90 percet) and the availability of green goods and services (80 percent).
"Access to nature for hiking and bicycling" is a definite boon for one American expat. In fact, the country's natural environment, although ranking 13th out of 60, is its lowest-rated subcategory. Luxembourg does even better when it comes to green energy, waste management, and the quality of its air and water.
Taiwan, most sustainable destination in Asia

The highest-scoring expat destination in Asia, Taiwan boasts 92 percent approval of its waste management and recycling, and 80 percent of the availability of green goods and services. But "the air pollution (in Taipei) is getting worse because it is too crowded," one expat complains.
Green goods and services are widely available, agree 82 percen of expats, as is green energy. However, 13 percent rate the Dutch environment negatively, 4 percet above the global average.
Well ahead of its neighbor Spain (#20), the country scores high for air quality (91 percent) and natural environment (95 percent). "I like the opportunity for gardening and growing our own food," says one expat.
Estonia scores in the Top 20 for every category and gets its highest marks for its natural environment. "A beautiful country with excellent air quality and open spaces," praises an Indian expat.
15. Costa Rica
Both the government and the people are very supportive of green policies, find 82 percent, resp. 67 percent of expats. "It's easy to live a healthy lifestyle with regard to the food, climate, clean air and water," says one. Costa Rica won the 2019 UN Champion of the Earth award and has pledged to go carbon neutral by 2050.
"The beauty of the environment" is one of the best things about living in Czechia, says a Russian expat. No less than 97 percent of expats agree.
77 percent of expats are happy about the availability of green goods and services in France, which is 14 percentage points above average. The country also scores well for waste management and recycling. In short, France has a "good, green and clean environment," one Iranian expat finds.
While ranking high on the quality of its nature, water and air, Australia scores low when it comes to government support for green issues (51 percent). Fortunately, expats see more interest among the general population (68 percent).
Expats rate the government's interest in green issues higher than globally average (77 percent versus 55 percent), but the Singaporean public's engagement for the same less than average (40 percent versus 48 percent). Of course, in a small, crowded place like Singapore, "(nature) spots are limited."
Spain's "scenery, diversity of places to visit and healthier environment" are what rate highly with one British expat. Its weak point is governmental and public support for green issues – but still slightly above the global average.
London is "polluted and noisy"

The highest-ranking country in the Middle East, Oman does especially well for natural environment (93 percent) and air quality (76 percent). However, only 50 percent are happy with the availability of green goods and services (versus 63 percent globally).
22. United Arab Emirates
Despite higher-than-average scores in some categories, the UAE's 52nd place out of 60 for the appreciation of its natural environment drags down its overall score.
Two in three expats rate Israel's air quality positively, 55 percent think the government cares about the environment (exactly the global average) and 51 percent thinks the public does too (slightly above global average).
The highest-ranked South American country, Ecuador scores especially well for its natural environment (95 percent). Its overall ranking is dragged down by lower scores for air and water quality. One Dutch expat sees "a lack of care for the environment."
Japan boasts a "high quality of life due to clean air and water, as well as many natural recreational places," reports a Malaysian expat. Waste management and recycling is rated highly (85 percent), but not the government's (27 percent) nor the public's (33 percent) engagement in green issues.
Expats are particularly satisfied with Ireland's air quality (16th) and natural environment (19th), but only 65 percent are content with the quality of the water and sanitation.
Biggest pluses: the public is into green issues (57 percent), the availability of green goods and services (75 percent) and green energy (66 percent). Belgium scores below average for air quality and one Danish expat complains about "poor green infrastructure."
28. United Kingdom
"(London) is very polluted and noisy," complains a Swiss expat. In fact, the UK's natural environment ranks just 43rd. On the upside, green goods and services are slightly more available than the global average.
The Gulf state ranks near the bottom for its natural environment and performs best for its government's green credentials (72 percent). One British expat regrets "the lack of green spaces."
30. United States
When it comes to green government policies, the U.S. ranks in the Bottom 10; but the country does a lot better in terms of the availability of green goods and services. "I like that basic services for living, such as access to clean water, are guaranteed," says one Venezuelan expat.
World map for the 'sustainable expat'
Sixty expat destinations ranked for sustainability, from best (orange) to worst (light blue). In between: fairly okay (brown), middling (grey) and not that great (dark blue).
While 94 percent of expats are happy with the quality of the natural environment, only 37 percent find Panama's waste management and recycling practices up to scratch (versus 60 percent globally). "There is a lot of litter on the streets and in the ocean," says one expat.
Italy's "beautiful landscapes and natural areas" earn the country high praise, but that is offset by "air pollution and heavy traffic," as the same expat explains.
Just like its overall score, Colombia is a mid-fielder in most categories. Its worst ranking is for air quality (47th), its best for the policy and people attitudes towards the environment (30th).
65 percent of expats appreciate the Qatari government's green efforts, but just 40 percent think the people feel the same. "There is a lack of green options, but things are changing," observes a Canadian expat.
Expats rate the quality of Hungary's water and sanitation higher than the global average (76 percent versus 72 percent), but its air quality significantly lower (49 percent versus 62 percent).
Poland is one of the few European countries to rank below average. No less than 60 percent of expats are unhappy with the air quality in Poland, compared to just 24 percent worldwide.
"St Petersburg is absolutely beautiful. There are many parks and green spaces, and the canals and the coast make it even better," gushes an American expat. But Russia is bigger than St Petersburg, and on the whole less pleasant. Water quality and waste management are just two categories rated well below the global average.
88 percent of expats like Argentina's natural environment, and 64 percent are satisfied with air quality (versus 62 percent globally) but the country performs average or worse on all other indicators.
Chile scores among the Bottom 10 for air quality, and not too well on many other indicators, but the quality of the country's natural environment (appreciated by 89 percent of expats) somewhat mitigates the result.
With 86 percent of expats lauding Malaysia's natural environment, the country scores above the global average in exactly one category. An Australian expat in Kuala Lumpur expresses concerns "about the air quality and waste disposal."
South Korea's "rather horrible" air
Seoul's air quality is so bad you can picture it. Only India's air is perceived as worse than South Korea's, according to the expat survey.
41. South Korea
Coming in on 59th place, South Korea scores particularly poorly for air quality. One Filipino expat even finds the Korean air "rather horrible". The water and sanitation quality are rated a lot higher, though.
Turkey's natural environment scores only slightly below average (78 percent versus 82 percent globally), as does the appreciation for its air quality (59 percent versus 62 percent). But the country scores well below global average when it comes to waste management (42 percent versus 60 percent). One expat laments the "traffic, pollution and lack of recycling" in the country.
Mexico is the worst performer among the North American destinations. No less than 35 percent of expats are dissatisfied with the quality of water and sanitation. One respondent mentioned the "lack of clean and operational public restrooms."
The island nation scores particularly well on air quality (68 percent), but worse than average on many other indicators, notably environmental awareness. "Garbage is just left anywhere," complains one British expat.
Greece's worst score is for waste management and recycling (53rd), but it does better for air quality (19th). Overall, 89 percent of expats appreciate Greece's nature, but the country is "not environmentally conscious," a Canadian expat says.
46. South Africa
Being Africa's best-ranked country at #46 is a bit of a Pyrrhic victory. In fact, South Africa scores near the bottom in many categories, including green energy options and government interest in green policies (both 59th).
The worst destination in South America when it comes to environment and sustainability. Just 23 percent of expats say the government supports green policies, only 32 percent think the population is interested in them. A Canadian expat lamented the "lack of empathy for the environment."
Morocco's biggest draws for expats in terms of environment and sustainability are its air quality (67 percent) and its nature (80 percent). But "I wish there was a greater awareness (with regards to) littering," complains an American expat.
49. Saudi Arabia
Best score: 50 percent of expats believe the Saudi government supports green policies (still 5 percent below the global average). "I don't like the total reliance on cars, the lack of recycling, and the lack of green spaces," an Australian expat says.
29 percent of expats are dissatisfied with China's natural environment, more than three times the global average (9 percent). "The air quality is terrible, and the people are packed tightly together," says an American expat.
Bad, worse, India
India scores worst in all three categories, but to be fair – some of its problems were imported from more developed countries.
51. Hong Kong
Hong Kong's two highest-ranked qualities are its natural environment and its water and sanitation infrastructure (both 37th). It does a lot worse for air quality (55th). "They still have landfill sites. And food waste is also a huge problem," observes a Hungarian expat.
The only European country in the Bottom 10, Malta performs poorly in all categories, but especially in terms of green policies. Only 33 percent of expats thinks the government cares about those, and only 48 percent think the same of the people. "It's a shame," says one British expat: "Wind farms and electric buses would be a good idea."
No less than 72 percent of expats are unsatisfied with Kenya's waste management and recycling, versus just 28 percent globally, and just 23 percent of expats believe Kenyans are interested in the environment, versus a global average of 48 percent.
The Philippines places in the Bottom 10 for each category. There is "no environmental care," laments one British expat.
53 percent of respondents agree that the Thai government is not supportive of green policies, more than double the global average (25 percent). An American expat lists "air pollution and the government's inability to enforce air pollution laws" as their least favorite aspect of expat life in Thailand.
Expats rate only India and South Korea as having worse air quality than Vietnam. A Dutch expat lists "air pollution, noise, bad waste management and rodents" as things he does not like about living in Vietnam.
50 percent of expats are unhappy about the state of Indonesia's water and sanitation infrastructure (vs. just 15 percent worldwide). "There is no waste management. All rubbish is going to the rivers and into the ocean," says a German expat.
The country on the Nile scores among the worst three in all of the survey's categories. There seems to be "no care for the environment," says a Polish expat. A French expat in Cairo laments the absence of "organic or pesticide-free foods".
Only 12 perent of expats are pleased with Kuwait's natural environment. That the emirate's worst result, but not the only bad one. "Poor sanitation and inept waste management" are among the worst things in Kuwait, says one Australian expat.
India is the worst destination for all three categories. 87 percent of expats are dissatisfied with India's waste management and recycling efforts, 82 percent rate the air quality poorly (with 55 percent saying it's "very bad"), and 69 percent are unhappy with the quality of the water and sanitation infrastructure.
World Bank data suggests India's output of renewable energy is 15%, significantly lower than the global average of 23 percent. However, in terms of the ubiquitous rubbish in India, it should be noted that the country has been used by western countries as a dumping ground for plastic waste.
Strange Maps #1053

All this from a wad of gum?
- Researchers recently uncovered a piece of chewed-on birch pitch in an archaeological dig in Denmark.
- Conducting a genetic analysis of the material left in the birch pitch offered a plethora of insights into the individual who last chewed it.
- The gum-chewer has been dubbed Lola. She lived 5,700 years ago; and she had dark skin, dark hair, and blue eyes.
Five thousand and seven hundred years ago, "Lola" — a blue-eyed woman with dark skin and hair — was chewing on a piece of pitch derived from heating birch bark. Then, this women spit her chewing gum out into the mud on an island in Denmark that we call Syltholm today, where it was unearthed by archaeologists thousands of years later. A genetic analysis of the chewing gum has provided us with a wealth of information on this nearly six-thousand-year-old Violet Beauregarde.
This represents the first time that the human genome has been extracted from material such as this. "It is amazing to have gotten a complete ancient human genome from anything other than bone," said lead researcher Hannes Schroeder in a statement.
"What is more," he added, "we also retrieved DNA from oral microbes and several important human pathogens, which makes this a very valuable source of ancient DNA, especially for time periods where we have no human remains."
In the pitch, researchers identified the DNA of the Epstein-Barr virus, which infects about 90 percent of adults. They also found DNA belonging to hazelnuts and mallards, which were likely the most recent meal that Lola had eaten before spitting out her chewing gum.
Insights into ancient peoples
The birch pitch was found on the island of Lolland (the inspiration for Lola's name) at a site called Syltholm. "Syltholm is completely unique," said Theis Jensen, who worked on the study for his PhD. "Almost everything is sealed in mud, which means that the preservation of organic remains is absolutely phenomenal.
"It is the biggest Stone Age site in Denmark and the archaeological finds suggest that the people who occupied the site were heavily exploiting wild resources well into the Neolithic, which is the period when farming and domesticated animals were first introduced into southern Scandinavia."
Since Lola's genome doesn't show any of the markers associated with the agricultural populations that had begun to appear in this region around her time, she provides evidence for a growing idea that hunter-gatherers persisted alongside agricultural communities in northern Europe longer than previously thought.
Her genome supports additional theories on northern European peoples. For example, her dark skin bolsters the idea that northern populations only recently acquired their light-skinned adaptation to the low sunlight in the winter months. She was also lactose intolerant, which researchers believe was the norm for most humans prior to the agricultural revolution. Most mammals lose their tolerance for lactose once they've weaned off of their mother's milk, but once humans began keeping cows, goats, and other dairy animals, their tolerance for lactose persisted into adulthood. As a descendent of hunter-gatherers, Lola wouldn't have needed this adaptation.
A hardworking piece of gum

These findings are encouraging for researchers focusing on ancient peoples from this part of the world. Before this study, ancient genomes were really only ever recovered from human remains, but now, scientists have another tool in their kit. Birch pitch is commonly found in archaeological sites, often with tooth imprints.
Ancient peoples used and chewed on birch pitch for a variety of reasons. It was commonly heated up to make it pliable, enabling it to be molded as an adhesive or hafting agent before it settled. Chewing the pitch may have kept it pliable as it cooled down. It also contains a natural antiseptic, and so chewing birch pitch may have been a folk medicine for dental issues. And, considering that we chew gum today for no other reason than to pass the time, it may be that ancient peoples chewed pitch for fun.
Whatever their reasons, chewed and discarded pieces of birch pitch offer us the mind-boggling option of learning what someone several thousands of years ago ate for lunch, or what the color of their hair was, their health, where their ancestors came from, and more. It's an unlikely treasure trove of information to be found in a mere piece of gum.
The non-contact technique could someday be used to lift much heavier objects — maybe even humans.
- Since the 1980s, researchers have been using sound waves to move matter through a technique called acoustic trapping.
- Acoustic trapping devices move bits of matter by emitting strategically designed sound waves, which interact in such a way that the matter becomes "trapped" in areas of particular velocity and pressure.
- Acoustic and optical trapping devices are already used in various fields, including medicine, nanotechnology, and biological research.
Sound can have powerful effects on matter. After all, sound strikes our world in waves — vibrations of air molecules that bounce off of, get absorbed by, or pass through matter around us. Sound waves from a trained opera singer can shatter a wine glass. From a jet, they can collapse a stone wall. But sound can also be harnessed for delicate interactions with matter.
Since the 1980s, researchers have been using sound to move matter through a phenomenon called acoustic trapping. The method is based on the fact that sound waves produce an acoustic radiation force.
"When an acoustic wave interacts with a particle, it exerts both an oscillatory force and a much smaller steady-state 'radiation' force," wrote the American Physical Society. "This latter force is the one used for trapping and manipulation. Radiation forces are generated by the scattering of a traveling sound wave, or by energy gradients within the sound field."
When tiny particles encounter this radiation, they tend to be drawn toward regions of certain pressure and velocity within the sound field. Researchers can exploit this tendency by engineering sound waves that "trap" — or suspend — tiny particles in the air. Devices that do this are often called "acoustic tweezers."
Building a better tweezer
A study recently published in the Japanese Journal of Applied Physics describes how researchers created a new type of acoustic tweezer that was able to lift a small polystyrene ball into the air.
Tweezers of Sound: Acoustic Manipulation off a Reflective Surface youtu.be
It is not the first example of a successful "acoustic tweezer" device, but the new method is likely the first to overcome a common problem in acoustic trapping: sound waves bouncing off reflective surfaces, which disrupts acoustic traps.
To minimize the problems of reflectivity, the team behind the recent study configured ultrasonic transducers such that the sound waves that they produce overlap in a strategic way that is able to lift a small bit of polystyrene from a reflective surface. By changing how the transducers emit sound waves, the team can move the acoustic trap through space, which moves the bit of matter.
Move, but don't touch
So far, the device is only able to move millimeter-sized pieces of matter with varying degrees of success. "When we move a particle, it sometimes scatters away," the team noted. Still, improved acoustic trapping and other no-contact lifting technologies — like optical tweezers, commonly used in medicine — could prove useful in many future applications, including cell separation, nanotechnologies, and biological research.
Could future acoustic-trapping devices lift large and heavy objects, maybe even humans? It seems possible. In 2018, researchers from the University of Bristol managed to acoustically trap particles whose diameters were larger than the sound wavelength, which was a breakthrough because it surpassed "the classical Rayleigh scattering limit that has previously restricted stable acoustic particle trapping," the researchers wrote in their study.
In other words, the technique — which involved suspending matter in tornado-like acoustic traps — showed that it is possible to scale up acoustic trapping.
"Acoustic tractor beams have huge potential in many applications," Bruce Drinkwater, co-author of the 2018 study, said in a statement. "I'm particularly excited by the idea of contactless production lines where delicate objects are assembled without touching them."
Australian parrots have worked out how to open trash bins, and the trick is spreading across Sydney.
- If sharing learned knowledge is a form of culture, Australian cockatoos are one cultured bunch of birds.
- A cockatoo trick for opening trash bins to get at food has been spreading rapidly through Sydney's neighborhoods.
- But not all cockatoos open the bins; some just stay close to those that do.
Dumpster-diving trash parrots
In a study about these smart birds just published in Science, researchers define animal culture as "population-specific behaviors acquired via social learning from knowledgeable individuals."
Co-lead author of the study Barbara Klump of the Max Planck Institute of Animal Behavior in Konstanz, Germany says, "[C]ompared to humans, there are few known examples of animals learning from each other. Demonstrating that food scavenging behavior is not due to genetics is a challenge."
An opportunity presented itself in a video that co-author Richard Major of the Australian Museum shared with Klump and the other co-authors. In the video, a sulphur-crested cockatoo used its beak to pull up the handle of a closed garbage bin — using its foot as a wedge — and then walked back the lid sufficiently to flip it open, exposing the bin's edible contents.
Major has been studying Cacatua galerita for 20 years and says, "Like many Australian birds, sulphur-crested cockatoos are loud and aggressive." The study describes them as a "large-brained, long-lived, and highly social parrot." Says Major, "They are also incredibly smart, persistent, and have adapted brilliantly to living with humans."(Research regarding some of the ways in which wild animals adapt to the presence of humans has already produced some fascinating results and is ongoing.)
Clever cockie opens bin - 01 youtu.be
The researchers became curious about how widespread this behavior might be and saw a research opportunity. After all, says John Martin, a researcher at Taronga Conservation Society, "Australian garbage bins have a uniform design across the country, and sulphur-crested cockatoos are common across the entire east coast."
Martin continues, "In 2018, we launched an online survey in various areas across Sydney and Australia with questions such as, 'What area are you from, have you seen this behavior before, and if so, when?'"
Word gets around

Although the cockatoos' maneuver was reported in only three suburbs before 2018, by the end of 2019, people in 44 areas reported observing the behavior. Clearly, more and more cockatoos were learning how to successfully dumpster dive.
As further proof, says Klump, "We observed that the birds do not open the garbage bins in the same way, but rather used different opening techniques in different suburbs, suggesting that the behavior is learned by observing others." One individual bird in north Sydney invented its own method, and the scientists saw it grow in popularity throughout the local population.
To track individual birds, the researchers marked 500 cockatoos with small red dots. Subsequent observations revealed that not all cockatoos are bin-openers. Only about 10 percent of them are, and they are mostly males. The other cockatoos apparently restrict their education to a different lesson: hang around with a bin-opener, and you will get supper.
Thanks to the surveys, the researchers consider the entire project to be a valuable citizen-science experiment. "By studying this behavior with the help of local residents, we are uncovering the unique and complex cultures of their neighborhood birds."
