Emerald is a secure browser app that reveals the actual fuel consumption and CO2 emissions of every flight worldwide — and prioritizes them based on your ideal schedule and price to help you quickly make the most eco efficient choice.
Because Emerald seamlessly integrates with your favorite travel sites, everything you need to compare and book is in one convenient place. Just search as you normally do, and you’ll see Emerald’s eco ratings next to each flight option. It really is that simple.
How much of a difference can Emerald make? Let’s take LA to NYC as an example. A typical Expedia search will offer plenty of choices. Yet on a given result page, fuel use between flights can vary as much as 50%. Emerald not only highlights the most efficient flights that meet your criteria, but can often find one at the same or lower fare — so you can make a smarter choice without giving up a thing.
If we all take more efficient flights when we can, the results can be huge. Together, we can seriously reduce carbon emissions, save fuel, and use our spending power to reward airlines for being eco friendly. Right now, Emerald works with all major desktop browsers (sorry, no tablets or mobile devices just yet). Why not take it on a test flight now? Installation only takes a few seconds.
