Once upon a time labelling someone a tree-hugger was meant to serve as an insult, but tree-hugging or being green or whatever you like to call it is fast gaining street-cred. Cate Blanchett has recently joined a growing crowd of celebrities taking their homes off-grid. She recently converted her home in the Hunters Hill district of Sydney, into a “green house”, fully powered by solar energy. And now New York, possibly the world’s most stylish city, is showing us that style and sustainability can go hand-in-hand with OZOcar, the first eco-luxury private car service in New York, and possibly the world. And with services set to roll out in London, Boston, Washington DC, Los Angeles and San Francisco by year end, it looks like tree-hugging is here to stay.
