How much pollution does your flight produce?

If you are worried about the environmental impact of your travel, a Vermont technology company has come up with an app that can help you choose which flight emits less pollution.

The eco-minded tech firm, Brighter Planet, developed an app called Careplane that uploads into your Chrome, Safari or Firefox browser. It launches when you search for flights on specific travel websites but works particularly well with Kayak. The app calculates pollution from each flight based on historic flight data, including plane weight, the average percentage of filled seats and fuel efficiency, among other factors.

When you search out a flight, the app will post the total number for the pounds of greenhouse gases produced by the flight.

For example, a nonstop round trip from Los Angeles International Airport to the Norman Y. Mineta San Jose International Airport on small regional jets will generate 618 pounds of greenhouse gases.

In contrast, a nonstop round trip from Los Angeles to San Francisco on a larger carrier will generate 730 pounds of pollution, according to the program.

Said Brighter Planet spokesman Robbie Adler: “Where cost and timing are roughly equal, anyone who is environmentally minded can choose a flight and consider the environmental impact.”
