CO₂  is a significant factor in global warming. And air transport accounts for 2% of it. That's a figure airlines are working hard to limit - investing in new, more fuel-efficient aircraft while we push for shorter routes and improved air traffic control.

We're also making a lot of small changes that, when applied over millions of flights, make a big difference. For instance, to make aircraft lighter, we've even reviewed the number of ice cubes carried onboard.

So what's an ice cube in the grand scheme of things? At the very least, it's proof that we take our responsibilities seriously.

Flying’s a wonderful thing.
