Kylie Kwong is a well known Australian celebrity chef. What is probably less well known is her passion for the environment. A commitment well demonstrated via her Sydney chinese restaurant, Billy Kwong.

This is the most heartbreaking story we've read all week, and if the idea of a baby whale trailing after a yacht and trying to suckle from it doesn't make you go "awww," then that lump of muscle you call your ticker has been

Last month the City of Sydney declared that it had become Australia’s first carbon neutral government. It is important to note that whilst the total area of this southern metropolis is said to be equal to the size of London

It is an undisputed truth that the majority of American cities have incomplete bicycling infrastructures. This is perhaps especially true in Los Angeles, where

It's a safe bet that few, if any, of Sydney's bicycle commuters go with penny farthings as their two-wheeler of choice. The outdated ride (popular in the 1870s) is most used these days for its retro value and the

Planning your holiday party schedule in New York City can be calendar jujitsu, what with work parties, friends parties, family parties, but there are also a few green themed parties that the sustainably minded New Yorker

In our conventional, resource-intensive food and building industries, 'waste-free' may seem like an alien concept, which makes projects like Australia's Greenhouse all the more impressive. Touted as a

The world’s largest permanent interactive light installation has been installed in Sydney's recently revitalized Darling Quarter.

Sydney sees cycling skyrocket as it implements its 2030 green city plan.

A trio of awesome fish bikes made a rousing debut at this arts festival in Australia.

With everything happening in one space, studio apartments can often feel too cluttered. This Sydney apartments gets a space makeover with the addition of a clever multifunctional unit that partitions the space and stores things out of sight.

Decluttering techniques are a big trend now. This small apartment is designed with organizational principles right from the start.

Instead of trashing these old treads, they have been made into a inter-looping work of art in the same station.

Built on top of an existing garage, this laneway house in Australia makes use of what's already there.

Are they good for everyone or just about making money and getting rid of workers?

A recent post that claimed readers absorb less from e-books. I wonder (and so do many commenters) if that's really true.

Some people do; others use a keyboard for everything and have forgotten how. What about you?

The Resilient Design Institute suggests we should all have six weeks of food in our homes. Too much or too little?

The designer Tom Ford takes FIVE of them every day. That's a bit much.

I think open kitchens are greener and more efficient, but others like a separation.

This is one area of measurement where perhaps the Americans, Liberians and Burmese get it right.

It's a thing of beauty but really expensive. Poll: Hütte or Nüts?

With people living in smaller spaces and with better toilets, perhaps it is.

The modern update of Abraham Maslow's hierarchy of needs rings very true.

The extremely dated "It ain't easy being green" title of this Trulia survey actually misinterprets the data; judging by the questions they asked, it is perfectly easy being green; it just ain't cheap.

Which of these two images does your place look like?

The results are often surprising.

Bananas are already in a perfect package. But is this even better?

The results of our annual survey are often surprising.

Our photo of the day comes from the 15th oldest U.S. national park.

Ozone, is a substance that like CO2, seems not only to require international treaties, but it likes cleaning stuff. Apparently NASA discovered it works a treat as a disinfectant, killing bacteria and making stains soluble at low temperatures. The

Ozone — best known for filtering out harmful UV light as a component of the Earth's stratosphere — could dramatically reduce plants' ability to act as a carbon sink and thus cause further accumulation of greenhouse gases in the atmosphere, according to

We recently told you of a study warning that global warming could prompt the large-scale collapse of the world's crops by 2080; now comes another study concluding that rising levels of ozone could achieve the same result by century's end. The study,

You can't blame them for trying: With the White House set to change hands in less than a year's time - likely bringing on board a more eco-friendly administration - industry groups have been pressing the EPA to squelch stricter air-quality standards

Talk about a lose-lose situation: On one hand, not taking any action to repair the hole would allow harmful UV radiation to percolate through; on the other hand, helping to accelerate its recovery could strengthen global warming by

Image from NASA updated: As many noted, I (idiotically) cited the Montreal Protocol's success here, which has nothing to do with reducing tropospheric ozone -- rather, it has to do with fixing the ozone layer. Thank you commenters, and my apologies for

Hosed by this theory or greenwashed? Photo by Tony Stl via Flickr On ABC's 20/20 last Friday, Nathan Myhrvold, Microsoft's former chief technology officer, and founder/CEO of Intellectual Ventures (IV), resurrected the idea of stretching a 2-inch

In July of 2007, the East Coast was slammed by a record-setting heat wave. From New York City to Washington, DC, temperatures averaged above 90 degrees Fahrenheit, causing more than 40 deaths.

Household cleaning products in the U.S. might soon be a little greener, thanks to a new rule in California that will require companies to reformulate products so they contain fewer volatile organic compounds, or

Ben Richmond at Motherboard highlights a climate change success story.

Hopefully someday we can say the same thing about an effective effort to combat greenhouse gas emissions.

New NASA study offers first direct proof that the ozone hole is recovering thanks to the Montreal Protocol treaty and the international ban on CFCs.

Among the more high risk methods of geoengineering, methods that reflect sunlight away from the Earth to counteract temperature rise are right up there in terms of potential unintended consequences. Well, a new piece of
