Depending on whom you ask, emissions from air travel make up 2-6 percent of the planet’s total CO2 emissions (as a whole, the transportation sector makes up about a quarter of those emissions). But airlines in particular have been getting a bad rap among some in the environmental community because of it, and a recent conference of European airline industries debated how to brighten their image.

One British strategic communications firm argued that the airline industry essentially needs a PR makeover. Steve Dunne of the Brighter Group went so far as to say that the industry risks sliding into a reputation akin to that of cigarette manufacturers in the U.S.: "The aviation industry is just not representing itself properly or effectively to put the lobbying efforts of the eco-warriors into some kind of perspective."

I’m not convinced the risk is that dramatic — at least here in the U.S. While there are certainly efficiency measures airlines should be considering — such as being towed to a starting point on the runway instead of burning fuel to get there – advocating a total ban on air travel as some do (or even very high taxes) is a losing cause (by the way, I want to hear a convincing argument as to why flying on a commercial plane isn’t public transportation, like taking the bus).

But the pollution problems for the industry could take off: The United Nations’ Intergovernmental Panel on Climate Change (IPCC) says that while the CO2 emissions per passenger kilometer have decreased, the increased number of passengers overall has negated that efficiency. Furthermore, the World Wildlife Fund predicts airlines to make up 15 percent of all global CO2 emissions by 2041.

So while the airlines may not be likened to cigarette manufacturers yet, they should consider some reputation management now. And there are good things happening: The International Air Transport Association says they saved 6 million tons of CO2 by shortening routes worldwide. Virgin’s Richard Branson just announced that he’s planning a 747 biofuel test flight for early next year, and Northwest put together a taskforce of employees and managers that came up with ways to cut inefficient fuel use by 31 million gallons per year. To keep up with the increasing number of passengers and the increasing concern about global warming (including carbon regulation), however, the airlines industry will have to continue decreasing their contribution to the problem and keep telling the public about it. Telling their side of the story — while performing real, meaningful leadership — will keep their reputation from taking a nose dive.

The debate about carbon offsets rages on: Are they a true solution to encourage investment in clean, renewable energy and offset dirty fossil fuels? Or are they indulgences of the privileged that allow us to keep on with our polluting ways and a clear conscience?

TerraPass is a popular, for-profit seller of carbon offsets. They’ve leapt into the limelight with strategic partnerships like the one at Expedia.com, which allows customers booking travel reservations to also purchase carbon offsets to cancel out their transportation emissions. But this popularity has also made TerraPass a frequent target of carbon offset skeptics who argue that their customers use them for nothing more than a sort of "get out of polluting free" card.

So the company decided to take a close look at its customer base itself, and just completed a survey that examined customer behaviors and attitudes towards energy. Among the results, the company found the "indulgence factor" to be untrue among their customers.

While Terra Pass customers are buying carbon offsets to counteract their unavoidable dirty activities like driving a car, they are balancing it with other direct action and changes to their own lives. In general, they are doing much more than the average person is to make their lives clean and efficient, and carbon offsets are a component of that. For example, 64 percent have installed compact fluorescent light bulbs (personally, I think CFLs should be a requirement before you’re even allowed to buy offsets), 26 percent take public transportation to work, 6 percent have solar panels, 50 percent have contacted their elected official about global warming, and 69 percent contribute to "green" organizations.

Are offsets a "get out of polluting free" card? Not always. But whether you decide to purchase offsets yourself, first take a hard look at the immediate changes you can make to your own life. Energy efficiency measures are often the cheapest, fastest, and easiest way to shrink your own carbon footprint.

You’ve probably never considered crowds to be a renewable source of energy. Lucky for us, two smarty-pants grad students at MIT’s School of Architecture and Planning are trying to figure it out.

James Graham and Thaddeus Jusczyk envision harvesting the mechanical energy from human movement – like commuters in a train station or fans at a rock concert – for electricity. This “crowd farm” would be a responsive sub-flooring system and made up of blocks that depress slightly when people step on them. When the blocks slip against each other they would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current.

Crowds of people at a train station aren’t going to be enough to power the train itself: Graham and Jusczyk explain that thousands of people would be needed to make up the 28,527 steps needed to power a moving train for one second. But for smaller, very energy-efficient devices, the students’ idea could lead to something bigger: Their test case included a prototype stool that used the act of sitting to generate power. The weight of the body on the seat causes a flywheel to spin, which powers a dynamo that lights four LEDs (super-efficient lightbulbs).

The architecture students ultimately want an energy supply that’s integrated into a new sort of building system, one that harnesses the active power of humans to power a cleaner, more efficient lifestyle in the 21st century.

Mayors from the planet’s largest cities gathered in New York last week to discuss how global warming is impacting their cities now, how it may in the future, and what immediate action needs to be taken to slow it.

The “C40 Large Cities Climate Summit” has partnered with the Clinton Climate Initiative to tackle climate change now, rather than waiting for action from national governments. At the Summit, mayors shared best practices, identified collaborative projects, and planned for future action together. The Mayor of London, Ken Livingstone, explained why:

"The fight to tackle climate change will be won or lost in cities…We are not going to simply talk about what we could do, while the window of opportunity for preventing catastrophic climate change disappears. Every city here today is a leader in at least one aspect of the fight to tackle climate change."

Some of the cities' intiatives include:

• New York Mayor Michael Bloomberg’s controversial proposal for a congestion charge for Manhattan as part of the city's multi-billion dollar Green Plan.
• Toronto Mayo David Miller explained “Zerofootprint Toronto,” which helps residents understand how every aspect of their lives impacts the environment, and creates a network for people to join with friends, neighbors, and coworkers to create a virtual eco-community to create initiatives and measure results.
• Curitiba, Brazil’s Mayor Carlos Alberto Richa described a bus rapid transit system for his city to cut down on pollution from cars.
• Los Angeles Mayor Antonio Villaraigosa announced GREEN LA, an action plan to reduce the city’s carbon footprint 35 percent below 1990 levels. Villaraigosa said it is the most ambitious goal set yet by a major American city.

Summit organizers also invited business leaders in an effort to involve the private sector. Both parties discused how to work together under the conviction that fighting global warming – through innovation, transportation, and energy efficiency – is profitable.

There’s a lot of talk about China’s staggering amount of planned coal plants, and the narrowing gap between it and the U.S. for the title of Planet’s Biggest Carbon Dioxide Emitter. But China is examining at least one unique way to develop more sustainably.

Welcome to Dongtan, the world’s first CO2-free city. Developers are building this $1.3 billion eco-city just outside of Shanghai. Renewable energy will be used extensively, the layout of the city maximizes walking and biking rather than cars, and transport vehicles will run on batteries or hydrogen fuel cells. Other plans include recycling organic waste, green roofs, and rainwater capture.

Dongtan will cover an area about three-quarters the size of Manhattan on wetlands at the mouth of the Yangtze River. However, Peter Head of Arup, the London-based firm heading the planning, said the wetlands are not at risk from the development. From the Architectural Record:

“‘First of all, water usually discharged into the river will be collected, treated, and recycled within the city boundaries,” he says. ‘There will be a 2-mile buffer zone of eco-farm between city development and the wetlands.’ While farming is water intensive, relatively small amounts of water reach the plants themselves. Head says Dongtan ‘will capture and recycle water in the city and use recycled water to grow green vegetables hydroponically. This makes the whole water cycle much more efficient.’”

But what will the habitants do in this eco-utopia? City officials and consultants expect jobs in education like at the planned Institute for Sustainable Cities, and they anticipate attracting companies pursuing clean technologies, food research and production, and health care. Dongtan is also expected to rely heavily on ecotourism.

Designers hope CO2-free city will serve as a model for the rest of the urbanized world. Its first phase includes a marina village of 20,000 habitants that will be unveiled at the 2010 World Expo in Shanghai. Nearly 80,000 people are expected to live in the city by 2020, and eventually designers hope to see 500,000 citizens living the good, green life there.
