For most of the adventures, it all starts there. There are a few ideas you can keep in mind when flying to keep your carbon footprint to the minimum.
First of all, whenever possible, choose an airline that is working to cut down on emissions. They usually advertise it right on their landing page. The technology to make a real impact is still years away but there are some smaller steps the airlines can take, like upgrading to a more environmentally friendly fleet, using more environmentally friendly materials, reducing the use of single-use plastic on its flights or using electric support vehicles. Virgin Atlantic, Singapore Airlines, Cathay Pacific, Etihad, British Airways, and a few more are leading the way but luckily lots are changing for better.
When buying the ticket, choose non-stop flights and economy class. Non-stop flights are usually not the cheapest option, but if you book in advance you can get the ticket at a better price and reduce significantly your travel carbon emissions, since it’s actually take-off and landing that create most of the airplane’s carbon emissions. Flying economy will help the environment as well because in business and first class, there’s more space per passenger, meaning an inefficient use of space. The energy and fuel required to operate a plane are so large, so the more people that fit into a plane, the better.
During the flight there’s a lot you can do as well: take your own reusable cups/bottles for tea, coffee and water; take your own amenities so you don’t use the airline ones (single-use) and if you do not eat the food take it with you, whenever possible, since it will go to garbage after the flight.
