This progress is a combination of investments in more efficient aircraft and operational efficiencies.

"But we have even bigger ambitions. From 2020 we will cap net emissions. And by 2050 we will cut emissions to half 2005 levels. Accomplishing these targets means continued investment in new technology, sustainable fuels, and operational improvements," said Alexandre de Juniac, IATA's Director General and CEO.

IATA is the International Air Transport Association representing 290 airlines comprising 82% of global air traffic.

With a big push for electric planes, they could cut emissions even more. Check out Heart Aerospace, a Swedish company making a 19 seater electric aircraft.
