  THE AVIATION INDUSTRY HAS LONG FOCUSED ON ENVIRONMENTAL AND ENERGY EFFICIENCY.
However, meeting the target for 2050 demands expanded and simultaneous efforts, starting now, in two major areas:
• developing ultra energy-efficient aircraft, spanning propulsion, systems & equipment, weight, etc. • developing low-carbon fuels: biofuels, synthetic fuels and hydrogen.
  IMMEDIATE GAINS BY INTRODUCING NEW AIRPLANES
■ The expected growth in air travel will result in higher CO2 emissions in absolute value, while also significantly reducing emissions per passenger- kilometer because of the introduction of more energy- efficient new-generation planes. Less than one-quarter of the current fleet will still be in service in 20 years, and some 34,500 new airplanes will have entered service by then. In fact, the Covid-19 pandemic could well lead to the retirement of older aircraft, which would be replaced by new-generation planes with improved economic and environmental performance.
■ Replacement is the most accessible of the levers we can use to improve aviation’s carbon footprint. It means the advent of more modern airplanes, offering reduced fuel consumption. For example, the two single-aisle leaders, the Airbus A320neo (service entry in 2016) and Boeing 737 MAX (2017), are both powered by LEAP engines, designed by Safran as part of their joint company with GE, CFM International. The LEAP features 15% lower fuel consumption than the CFM56 engines which power the previous generation of these popular twinjets.
■ According to Safran’s estimates, the gradual introduction of latest-generation jetliners (A320neo, 737 MAX, 787, A350, 777X) will automatically reduce CO2 emissions per passenger-kilometer by 1% to 2% per year over the next 15 years.
Despite the impact of Covid-19, the global civil aircraft fleet should nearly double by 2040, growing from about 23,000 today to
more than
  40,000
in 2040.
