Just about the same time a study came out stating that, by and large, travelers preferred greener travel but didn't want to pay a lot more for it, Slate published this very practical Q&A about how to choose flights on environmentally responsible airlines.
The article doesn't offer specific airline suggestions, but it does outline how to assess whether or not the planes you're flying are better or worse on the eco-spectrum. Here's a quick rundown of what they suggest:
- Look for carriers flying new jets and planes with raked wingtips, since both tend to offer improved energy efficiency.
- Check airlines on-time records, since fuel is wasted on planes idling before takeoff.
- Fly nonstop whenever possible.
The article is peppered with other interesting tidbits, including why the Boeing 787 Dreamliner might be the greenest plane to date.
