Carta da Terra

"Estamos diante de um momento crítico na história da Terra, numa época em que a humanidade deve escolher o seu futuro. À medida que o mundo torna-se cada vez mais interdependente e frágil, o futuro enfrenta, ao mesmo tempo, grandes perigos e grandes promessas. Para seguir adiante, devemos reconhecer que, no meio da uma magnífica diversidade de culturas e formas de vida, somos uma família humana e uma comunidade terrestre com um destino comum. Devemos somar forças para gerar uma sociedade sustentável global baseada no respeito pela natureza, nos direitos humanos universais, na justiça econômica e numa cultura da paz. Para chegar a este propósito, é imperativo que nós, os povos da Terra, declaremos nossa responsabilidade uns para com os outros, com a grande comunidade da vida, e com as futuras gerações." (da CARTA DA TERRA)

Experts say car sharing may be important for global future

In the United States, 70 percent of people, 700 of every 1000, have a car. As the rest of the world joins the car classes, Americans, however, are thinking less of buying cars and more of sharing them. And, experts say, car sharing may be critical if we hope to keep emissions down and ensure enough supply of fossil fuels.

When John Sterman, a professor at the MIT Sloan School of Management, looks at cars and transportation systems in the not-too-distant future, he doesn’t like what he sees.
“If everybody in the world drove the way Americans do today, then there would be in 2050 about nine-plus billion people, according to the U.N., and those nine billion people would be driving 7.8 billion light duty vehicles.”

And those vehicles would require five times as much oil as is produced today, spewing out a lot more greenhouse gasses.
“And those cars would take up enough land that it would take an area the size of the whole country Bangladesh just for the parking spaces,” Sterman said.
But what’s the answer then if we all want cars? One thought: We share them. Sterman loves this idea. He says more people need to really think about what car ownership entails.

“The insurance, the registration, the taxes, the parking, the maintenance, all of that stuff that you pay for, whether you’re driving it or not,” Sterman said. “Most people, especially in cities, are coming to realize: No, this is a terrible thing. It’s hugely expensive to own a personal vehicle.”

In Boston, as well as more than 50 other cities in North America, the U.K., and Spain, you can rent a Zipcar by the hour or day. Robin Chase co-founded the company in Boston 13 years ago.
“We started with four cars and built it up from there,” Chase said.
Today, Zipcar has a fleet of nearly 10,000 vehicles and 760,000 members.
“Each car is used by 40 to 60 people, and of those people, 15 to 20 sell or avoid buying a car,” Chase said.
That’s a lot less congestion and emissions.

An opportunity for global expansion
Avis bought Zipcar earlier this month for about $500 million. With Avis’deeper pockets and vastly larger vehicle fleet, it could enable the Zipcar service, renting cars by the hour, to greatly expand.
Chase, though, is no longer affiliated with Zipcar. She’s working on another car sharing start-up in Paris and sees huge opportunities for growth in car sharing globally.

“I just spent the last two years in Paris, and throughout Europe, it’s a given and accepted fact that cities are going to all become shared cars. Over the next 20 years that’s what we will see," she said. "And as we think about Asia and in India, those densely-populated cities, American cities are 1/5 the population density of those cities.”

And those already-crowded Chinese and Indian cities don’t even have that many cars yet, either. David Friedman, the deputy director of the clean vehicles program at the Union of Concerned Scientists, points out there are about 700 cars per 1,000 people here in the United States.

“In China, there’s about 44 cars for every 1,000 people. In India, there’s even less, there’s only about 12 cars for every 1,000 people,” Friedman said. “So there’s a lot of room for China and India car ownership to grow. The question is: Are they going to take the U.S. model, where we’ve saturated car use? Or are they going to adopt car sharing?
"So they don’t follow the same path of congestion, pollution and poor air quality that we tried over the last 40 years as our car ownership exploded,” he said.

But do the Chinese want to share cars?
“Forget about it. No way. It’s not going to happen. Unthinkable,” said Michael Dunne, an independent car consultant based in Hong Kong.

Dunne said in Asia cars are a social statement.
“It’s an image factor, big image factor. So at the office you’d say, What kind of car are you driving? I’m driving a Honda. This guy over here has a Nissan. I have a Chevy. What about you? ‘Well, I’m sharing a car with somebody else. Gee. Oh, you’re sharing a car? That means you can’t afford one.’”
But that doesn’t mean attitudes can’t change. People just need a nudge, said Susan Shaheen, the co-director of the Transportation Sustainability Research Center at the University of California at Berkeley. Her research shows that car sharing has been growing faster in the U.S. than in Canada, for example.

“When we look at the difference between Canada and the U.S., U.S. governments typically were much more supportive toward the car sharing concept in terms of grants, subsidies, access to on-street parking, and those types of things," she said. "So I think the role of the government is really important. And I think the signal, in particular, that it sends to the population in China is very important.”

In Singapore, the government has been sending that signal: car taxes, tolls, and usage fees are making car ownership prohibitively expensive. It costs more than $65,000 just to buy a permit to own a car there.
No real surprise: some car sharing companies in Singapore are now open for business.
