Flying high above the clouds, Lufthansa flight 8400 to Shanghai is like no other.
It's carrying nearly 100 tons of cargo – including automotive parts, machinery and some pharmaceutical products.
But unlike other air freighters, which have a costly environmental footprint, this plane is adding no CO2 emissions. Once a week, Lufthansa Cargo operates one of the world's first regular flights powered by Sustainable Aviation Fuel (SAF). It's an expensive but greener alternative to traditional jet fuel.
