Aviation &Environment
In the early days of the jet age, speed and luxury were the drivers of intercontinental travel.
Today, our engines are at the cutting edge of efficiency. Our aircraft are more aerodynamic and lighter than ever before. Moreover, we are making huge improvements in our air traffic control efficiency, how we fly our aircraft and in developing more environmentally-friendly operations at airports. But we are still using the same fuel. That’s about to change. The world is turning to governments and business to reduce the human impact on climate change. And the aviation is about to embark on a new journey.
Sustainable biofuels are crucial to providing a cleaner source of fuel to power the world’s fleet of aircraft and help the billions of people who travel by air each year to lower the impact of their journey on our planet.
