What comes to mind when you think of royalty? Luxurious palaces, the Queen of England, and overused puns on Marie Antoinette's infamous one-liner?

How about chemical-free gardens, recycling, and sustainable seafood? Ruling families from around the globe are using their media magnetism and sovereign sway to draw attention to a variety of eco-causes, fighting climate change, greening their homelands, and making sure all that cake we're eating is organic too.

1. Prince Charles of England

An outspoken proponent of fighting climate change, Prince Charles has an across-the-board interest in environmental issues. He's advocated for tropical rainforest preservation through The Prince's Rainforests Project and brought attention to the rapid depletion of global fish stocks. After moving to the Highgrove country estate in Gloucestershire three decades ago, the prince took interest in back-to-basics farming and converted the Home Farm from conventional to organic food production. Deciding that this sustainable farming thing was a brilliant idea, he started Duchy Originals in 1992 to sell organic and sustainably produced goodies, from British tea classics to organic hair and body products.

2. Princess Basma bint Ali of Jordan

Princess Basma has earned a long list of awards and honors for her efforts to bring environmental issues into the limelight in Jordan. After becoming one of the first women in her country to earn navy diving certification, Princess Basma saw firsthand the damage that human waste and neglect have taken on the delicate coral reefs of Jordan's Red Sea coast. This inspired her to form the Jordan Royal Ecological Diving Society, which is focused on conserving Jordan's marine areas and educating citizens about the impacts of their activities on marine life. She also founded the Royal Botanic Garden, preserving the wide array of plants native to Jordan for generations to come. In recognition of these and many more initiatives, Princess Basma was honored with a spot on the U.N. Environment Program's Global 500 Roll of Honor.

3. Prince Albert II of Monaco

The website of the Prince Albert II of Monaco Foundation declares that sustainability and protecting the environment are challenges that require "urgent and concrete action," and Prince Albert II tries to walk the talk, implementing sustainable practices in his own country and urging the world to do likewise. Monaco hosted the second international Ocean in a High-CO2 World symposium last October, during which the Monaco Declaration [PDF] on ocean acidification was drafted, calling for nations of the world to take immediate action to reduce CO2 emissions and thereby prevent damaging changes to ocean chemistry. Prince Albert wrote a foreword to the declaration, urging political leaders to get with the program. Recently, he called for removal of the over-fished bluefin tuna from the menus of all restaurants in the United Kingdom (it's already off all menus and shelves in Monaco). He has also promoted energy efficiency as a way to combat climate change. For efforts such as these, the U.N. named him a Champion of the Earth in 2008.

4. Princess Lalla Hasnaa of Morocco

As president of the Mohammed VI Foundation for the Protection of Environment, Princess Lalla Hasnaa has worked toward the revival of green spaces, better water management, and sweeping environmental education initiatives in Morocco. Cleaning up beaches, urging young people to report on environmental issues, and improving air quality are all in a day's work for this green princess. She says her "heart as a mother and as a Moroccan" is "worried when thinking that our sons and daughters do not have the right to live in a country respecting nature and its beauty." Thanks to her good work, all of Morocco's kids might inherit a greener nation.

An avid bird enthusiast, Princess Takamado has championed the cause of avian conservation through her honorary presidency of BirdLife International, urging kids to get involved in the world of bird watching and establishing the Asia Bird Fund. In addition to her efforts on behalf of our feathered friends, she has spread the word about fragile ocean and Arctic environments through Lulie the Iceberg, a picture book for children about a breakaway iceberg's adventure from the Arctic to Antarctica--complete with a companion musical score featuring famed cellist Yo Yo Ma.

6. Princess Chulabhorn Walailak of Thailand

A chemist and medical researcher, Princess Chulabhorn has focused on genetic toxicology and the chemistry of natural products, studying, among other things, the health risks that air pollution poses to traffic police in Bangkok. She founded the International Center for Environmental and Industrial Toxicology, which was designated by the U.N. Environment Program as "a Center of Excellence," and the Chulabhorn Research Institute, which trains scientists and searches for solutions to problems related to the environment, agriculture, and health. In 2002, she was awarded the Environmental Mutagen Society Hollaender International Fellowship [PDF]. She has served as a special adviser to the U.N. Environment Program and was named by the U.N. to direct the Center of Excellence for Environmental and Industrial Toxicology.

7. Prince Hassan Bin Talal of Jordan

A supporter of the DESERTEC Foundation, which promotes massive solar power projects in North Africa, Prince Hassan (brother to Princess Basma) is a staunch advocate of clean, renewable energy. He delivered a swift kick (ahem) to fossil fuels by declaring that they are "a threat to our natural living conditions." Last year he gave a speech [PDF] before the United Nations General Assembly explaining how environmental issues relate to human security. For his efforts on behalf of the environment, this anti-petroleum prince was recognized as a 2007 Champion of the Earth by the U.N. Environment Program.

8. Queen Elizabeth II of England

Earlier this year, Queen Elizabeth (mother of Prince Charles) planted a chemical-free vegetable garden on a patch of the Buckingham Palace grounds--land that hasn't seen food production since the Victory Garden days of World War II. The queen has also expressed concerns about the effects of climate change on the poor and made the royal palaces more Earth-friendly by installing energy-efficient light bulbs and even a mini hydroelectric power plant for Windsor Castle.

9. Princess Maha Chakri Sirindhorn of Thailand

Princess Sirindhorn (sister to Princess Chulabhorn) has been involved in projects ranging from preserving the biodiversity of plant life in her country to improving water management. In an address on World Food Day in 2004, she spoke of how "biodiversity plays a key role in sustainable development and poverty alleviation." Recently she visited the Heliocentris headquarters in Berlin to talk about the future of renewable energy.

What do you have in common with the King of Sweden? If you recycle, then you'd feel right at home in his private kitchen, separating your imperial plastics from your aristocratic cans. King Carl Gustaf attributes his love for the environment to time spent outdoors with his nature-loving mother, but was inspired to take action against climate change after a voyage on an icebreaker with international climate scientists in 2004. He has since installed a pellet-fired boiler at Drottningholm Palace and launched a campaign to raise global awareness about climate change, an effort that won him special recognition in the U.N.-HABITAT Scroll of Honor in 2006. The king reconciles his love for cars with his concern for the environment by advocating for alternative fuels.

The sights and sounds of wind turbines don't seem to bother farmland birds, according to research published in the Journal of Applied Ecology. Scientists studied the effects of two wind farms in eastern England on 3,000 birds of 23 species, and found that only pheasants seemed to be disgruntled enough to move farther away from the turbines. (Incidentally, if we had a band, we'd call ourselves The Disgruntled Pheasants.) "This is the first evidence suggesting that the present and future location of large numbers of wind turbines on European farmland is unlikely to have detrimental effects on farmland birds," says coauthor Mark Whittingham. "This should be welcome news for nature conservationists, wind energy companies, and policymakers." However, the study did not focus on whether birds were killed by flying into turbines, which is a main concern of conservationists.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

In a decision that anti-coal activists say is a gamechanger, six Greenpeace protesters have been acquitted of nearly $53,000 in criminal-damage charges for painting "Gordon" on a British coal plant. The activists climbed a 650-foot coal-plant chimney last year with the intent to paint "Gordon bin it" in huge letters, aiming to pressure Prime Minister Gordon Brown to disallow new coal plants. They only got to "Gordon" before being served with a high court injunction. In court, the six used a "lawful excuse" defense, arguing that burning coal exacerbates climate change, thus putting property around the world "in immediate need of protection." Climate scientist James Hansen testified on their behalf, and the jury found in their favor. "This verdict marks a tipping point for the climate change movement," says chimney-scaler Ben Stewart. "If jurors from the heart of Middle England say it's legitimate for a direct action group to shut down a coal-fired power station because of the harm it does to our planet, then where does that leave government energy policy?"

What Do Coal and Dirty Dorm Rooms Have in Common?

Hundreds of protesters gathered outside Britain's Parliament Monday to protest the government's plan to build 15 eco-towns. The government is proposing communities characterized by sustainable construction, public transportation, green space, and walkability. It hopes to have five eco-towns built by 2016, and five more by 2020. Monday marks the last day of the government's first phase of consultation with local folks, who have largely shown little enthusiasm for the plan. Critics say new towns will burden existing infrastructure, be built on land that should remain undeveloped, and don't take into account the desires of local communities. The plan is "a thoroughly bad idea," says one protester, "unrealistic, unsustainable, and definitely not wanted." Says Marina Pacheco of the Campaign to Protect Rural England: "We are urging the government to go back to the drawing board."

Activists in the U.K. have announced that an annual weeklong climate camp, held last year to protest expansion of London's Heathrow Airport, will this summer be held at the site of a proposed coal-fired power plant in Kent. Which is not to say, of course, that they're not still pissed about Heathrow.

Greenpeace and other eco-activists have been protesting mightily against a planned third runway for London's Heathrow Airport, which would demolish the nearby town of Sipson and, say activists, be completely counter to Britain's ambitious carbon-cutting goals. The airport-expansion plan has brought significant opposition from both politicians and residents; the British government has yet to make a final decision, but opponents fear it's a foregone conclusion.

The British government is preparing a shortlist of sites for high-density, carbon-neutral eco-towns, but is coming under consistent protest from villagers who don't want 'em nearby. Many residents living near the proposed sites have concerns that, eco or not, new development will take over agricultural land, increase traffic, and burden local infrastructure. Says Mark Sullivan of the Campaign to Protect Rural England, "[Eco-towns] will never be self-sustaining, effective communities if they are sited in the wrong places."

London Mayor Ken Livingstone tripled the fee drivers of the most-polluting vehicles will have to pay to enter the city center beginning in October, from about $16 to $49. The so-called congestion charge was introduced in 2003 in an effort to decrease traffic and greenhouse-gas emissions, encouraging Londoners and visitors to use public transportation instead of cars. Today's changes to the congestion-fee program include exempting drivers of the most-efficient vehicles, including the Toyota Prius, from the charge. Another change would erase the exemption that had been in place for residents who live within the congestion zone, subjecting drivers of the most-inefficient SUVs and luxury cars to the $49 a day charge for driving in downtown London even if they live there. "I believe that this groundbreaking initiative will have an impact throughout the world with other cities following suit as they step up their efforts to halt the slide toward catastrophic climate change," Livingstone said.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

Echoing recent concerns of the U.S. military, the British Ministry of Defense has stepped up its opposition to some wind power projects due to concerns over turbines' impact on radar installations. The Ministry of Defense has lately objected to at least four proposed wind farms claiming they'd cause radar troubles; wind farm proponents fear more such opposition in the future. The agency's turbine-averse stance is based on a recent study that found wind farms sited close to radar installations could make it impossible to detect aircraft and could be a threat to national security. "The MoD trial results were alarming as they confirmed a greater impact than that previously thought," said squadron leader Chris Breedon. "This in turn required a more robust approach to wind turbine assessments." Even before the recent report, the U.K. military voiced opposition to wind turbines on the same grounds, fearing radar troubles. The agency said it won't impose an all-around ban on wind farms but that it would evaluate applications on a case-by-case basis.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

The World Wildlife Fund has been trying to gather support to establish a network of marine protected areas in the Southern Ocean in an attempt to mitigate increasing ecological pressures in the area from climate change, invasive species, and commercial fishing. The plight of Antarctica and the Southern Ocean has often been overlooked compared to the rapidly melting Arctic on the other side of the world. But recently the Antarctic has been getting increased attention -- not just for its melty future, but the predicted bonanza of ocean-floor mining and other exploration that the melt could open up. Britain's Foreign Office has confirmed it's preparing to submit claims to the United Nations for rights to some 385,000 square miles of sea floor in the Southern Ocean under the U.N. Law of the Sea Treaty. Britain hopes to convince the U.N. to declare the area an extension of its territories, including the British Antarctic Territory as well as the Falkland Islands and South Georgia off the southeast coast of Argentina. New Zealand and Australia have also claimed parts of the Southern Ocean; Argentina and Chile will likely do the same.

A judge has ruled on a British citizen's accusation that the United Kingdom's distribution of An Inconvenient Truth to secondary schools amounts to political indoctrination. And the strange, strange verdict is: Yes, the documentary can be shown in schools -- as long as teachers follow guidelines to not promote Al Gore's "partisan political views" to impressionable schoolchildren. Because remember in the movie when Al Gore said "Kids, climate change is bad so you should always vote Democrat?" Yeah. Us neither.

Climate camp kicks off at London's Heathrow Airport

The controversial Climate Camp at London's Heathrow Airport kicks off today, with as many as 2,000 people expected to attend at its height. The weeklong protest is aimed at airport officials' plans to build a new runway, and at the role of aviation in climate change. "Aviation emissions aren't even part of our climate budget ... and for that reason the government has just given the aviation industry a green light to expand when the rest of us are being told we have to reduce our emissions," said one Greenpeace campaigner. Organizers are planning trainings, debates, and direct actions. With rumors spreading that the protesters plan to unleash bomb hoaxes, anxious airport officials and as many as 1,800 police are on guard. But the campers -- who surmounted an injunction leveled against them earlier this month -- say their aims are peaceful. "This isn't just about people's freedom to fly," said one, "this is about people's freedom to live on a planet that has a future."

Governments ruffled by climate kerfuffles in England, Australia

A couple of government climate kerfuffles have broken out: In Britain, a leaked briefing paper says the country won't meet a European Union target of 20 percent renewable energy by 2020, and suggests lobbying other nations for a more flexible interpretation of the goal or using "statistical interpretations" to shine things up. Written for government ministers by what is now the Department for Business, Enterprise, and Regulatory Reform, the memo says the best Britain can hope for is 9 percent by 2020, and even that would be a challenge. Officials and activists are shocked at the stance, which Rajiv Bhatia of renewable-energy distributor Alternergy calls a "betrayal of the highest order." Meanwhile, in Australia, four members of parliament caused a furor by writing a dissenting chapter to a cross-party report on climate change, saying the science is unsettled. Public outcry forced Prime Minister John Howard, a fellow Liberal and climate hesitator himself, to disavow their comments.

Organic farmers in Africa fear for their livelihoods as U.K. frets over food miles

Small-scale organic farmers in Kenya and other African countries are waiting anxiously to find out whether the U.K.'s main organic certifier, the Soil Association, will withdraw organic certification from food items that are flown in from far-flung regions. Concerned that the air-freighting of food contributes to global warming, the Soil Association has been contemplating the move as a way to get Brits to buy local. Critics of the proposal say it could destroy the livelihoods of tens of thousands of Africans who work on organic farms. Critics also question the assumption that food produced in Britain has a lower carbon footprint than food flown in from developing countries, noting that British farmers may heat greenhouses in cold climates, use tractors, and drive to their fields in cars. Says Elijah Koinange of the Organic Farmers' Group in Kenya, "They say our products are polluted, but the consumers take jets and create much more pollution than we do."

England walloped by historic floods

It's a "summer of suffering" in England, as severe flooding wreaks havoc across the country. This weekend, floods in the central and southern part of the country left more than 350,000 people without drinking water and forced the evacuation of hundreds from their homes. The worst part, observers say, is that the waters are still rising -- and are on track to outpace record flooding from 1947. The crisis follows a June flood in the north that killed seven people and left 7,000 at least temporarily homeless. With the swollen Thames and Severn rivers threatening to burst and criticism rising almost as quickly, newly installed Prime Minister Gordon Brown flew over the affected areas and pledged to increase flood-defense spending. "Obviously like every advanced industrial country we're coming to terms with some of the issues surrounding climate change," he said at a press conference, noting that the government would review the future siting of infrastructure and homes with climate in mind.

Brits raise a fuss over less-frequent rubbish collection

Baffled Brits are raising a stink over a policy that's become popular with local councils in their country: collecting trash every two weeks instead of weekly. Enacted by about 40 percent of councils, the practice -- which alternates the pick-up of trash and recyclables -- aims to encourage recycling and meet an E.U. goal of lessening landfill burdens. But horrified householders say the two-week lag lures flies, maggots, and rats to their trash piles, posing a public-health risk as well as being flat-out foul. Now these critics have the backing of a House of Commons committee, which released a report saying that the increasingly common method is "clearly not appropriate to all areas, particularly highly urban areas characterized by much shared accommodation." The committee also heaped scorn upon a government plan to offer financial incentives for recycling, suggesting that a complicated system of taxes and rewards could lead to protests, and called for more study on the whole revolting topic.
