Put me down for as a solid "skeptical" on this one, but several airline companies are promoting themselves as a greener option in air travel.

This morning, Airbus, the France-based aerospace manufacturer, made the claim that their A380 superjumbo -- the world's largest airliner -- could save the planet. They've even got a slogan, "Saving the planet, one A380 at a time," and have been calling the jet the "gentle giant." They say the plane can fly more passengers further and more fuel-efficiently than other models, which results in 17 percent less fuel used per seat than other large aircrafts. This model has been around since 2005, but this is the first time Airbus has come out touting its eco-cred.

On a similar note, easyJet Plc., a low-cost British airliner, made an announcement last week that they've developed a model for an ecojet that releases half the carbon of an average plane. The plane would travel at lower speeds, use lighter materials, and update more traditional plane models for better fuel efficiency and pollution reduction. It would cut carbon emissions by 50 percent and nitrogen emissions by 75 percent, they claim. They're in talks with leading manufactures Airbus and Boeing, and hope to get the plane created by 2015.

Any news about greening the airline industry is good news, as it's responsible for at least 2 percent of total global emissions. But how legit are these claims, and how close are we to getting something like "ecojet" off the ground? Not legit or close enough, I would argue. In the meantime, the best answer is to fly less, or not at all, and to make sure that the flights that do take off are full. That's a much more immediate solution to the problem.
