Atmospheric pollution

Decreasing atmospheric pollution has been one of the main design criteria for Safran engines for a number of decades.

Limiting atmospheric releases

We continuously strive to improve the efficiency of our engines. The combined improvements in fuel consumption, materials and the use of alternative fuels all help decrease atmospheric pollution.

All of these actions help improve air quality around airports, by decreasing emissions of CO2, oxides of nitrogen (NOx), volatile organic compounds (VOC), carbon monoxide (CO) and particles.

The CO2 and NOx generated by commercial airplanes should decrease by 75% and 90%, respectively, by about 2050. These are the ambitious goals set in 2012 by ACARE (Advisory Council for Aviation Research and Innovation in Europe).


Engine emissions: impressive progress in the last 50 years:

50 %
reduction in carbon monoxide
90 %
reduction in smoke and unburned hydrocarbons
