Carbon-neutral is hip, but is it green?

Carbon-neutral is hip, but is it green?

The rush to go on a carbon diet, even if by proxy, is in overdrive.

In addition to the celebrities — Leo, Brad, George — politicians like John Edwards and Hillary Clinton are now running, at least part of the time, carbon-neutral campaigns. A lengthening list of big businesses — international banks, London's taxi fleet, luxury airlines — also claim "carbon neutrality." Silverjet, a plush new trans-Atlantic carrier, bills itself as the first fully carbon-neutral airline. It puts about $28 of each round-trip ticket into a fund for global projects that, in theory, squelch as much carbon dioxide as the airline generates — about 1.2 tons per passenger, the airline says.

Charles Komanoff, an energy economist in New York, said the commercial market in climate neutrality could have even more harmful effects.

It could, by suggesting there's an easy way out, blunt public support for what will really be needed in the long run, he said: a binding limit on emissions or a tax on the fuels that generate greenhouse gases.

"There isn't a single American household above the poverty line that couldn't cut their CO2 at least 25 percent in six months through a straightforward series of fairly simple and terrifically cost-effective measures," he said.

First Successful Demonstration of Carbon Dioxide Air Capture Technology Achieved by Columbia University Scientist and Private Company

Global Research Technologies, LLC (GRT), a technology research and development company, and Klaus Lackner from Columbia University have achieved the successful demonstration of a bold new technology to capture carbon from the air. The "air extraction" prototype has successfully demonstrated that indeed carbon dioxide (CO2) can be captured from the atmosphere. This is GRT’s first step toward a commercially viable air capture device.
