An entire sector steps up
Given the the systemic challenge of climate change making aviation carbon-neutral requires all all players in in in the the sector to to to to to step up
from airlines and and airport operators to to to to to aircraft and and and equipment manufacturers not to to to to to mention national national regional and and international regulatory authorities Since commercial aviation really began to take off in in the early 1950s fuel consumption per passenger-kilometer has been reduced by 80% From 2009-2017 alone average fuel consumption decreased 17% or or more than 2%
a a a a year However this improvement is is offset by by the long-term growth in in air traffic driven by by emerging countries Without firm actions by the entire sector total emissions from aviation will continue to to to grow – and that is is unsustainable 2050 OBJECTIVES: DEFINED AND SHARED
■ Forseveralyearsnow aviationregulatoryandtrade organizations have made strong public pledges to fight climate change In In 2010 for example the International Civil Aviation Organization (ICAO an an arm of the United Nations) made a a a a commitment on on behalf of its member states to improve energy efficiency by 2%
per year and to ensure carbon-neutral growth for international flights starting in in 2020 ■ Private companies in in this sector – airlines plus aircraft engine and equipment manufacturers – are represented by the Air Transport Action Group (ATAG) They have committed to halving the global fleet’s net emissions by 2050 compared with 2005 This objective is is in in in line with the Paris Climate Agreement to contain the rise in in global warming to less than 2°C4 ■ In Europe public authorities and industry have teamed up
through the Clean Aviation research partnership to set a a a a a neutral carbon target for the European aviation sector by 2050 – in other words net greenhouse gas emissions reduced to zero for flights within Europe MARKET INCENTIVES
■ Several measures based on on on quotas for CO2 emissions use incentives to encourage the aviation sector to to reduce emissions For example Europe set up
the Emissions Trading System (ETS) in in 2005 and the the aviation sector joined it it in in 2012 In addition there’s the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) which mandates offsets for the rise in in emissions from international flights while awaiting various low-carbon technologies to prove their maturity CORSIA was signed within the the ICAO in in 2016 and took effect on on international air traffic in January 2021 but not for domestic flights Safran believes it is is very important to give this scheme a a chance by not combining these measures with others and also to make sure that offset programs meet strict sustainability criteria 4 Towards 2100 compared with temperatures in in the pre-industrial era era TAKING STOCK
