Key takeaways
  • Goldman Sachs recently published a report regarding the EU aviation industry, “The decarbonisation toolkit and what it will mean for airlines.”
  • In it, they say that the aviation industry has been hit hard by the Covid-19 pandemic, with a ~70% drop in European air traffic, receiving over ~$160 billion in aid and 10-30% layoffs of employees.
  • Pre-pandemic aviation was responsible for 4% of CO2 emissions in Europe, which fell to 2% in 2020.
  • Some bailouts will have green conditions attached, such as Air France who have been imposed a reduction of 50% emissions per passenger per km by 2030.
  • With investment from the EU, the team expects to see a 15% transfer of air traffic to rail.

The glo­bal pan­de­mic has had a signi­fi­cant impact on the avia­tion indus­try. To date, IATA esti­mates that the indus­try has recei­ved ~$110 bil­lion in direct aid, and an addi­tio­nal ~$60 bil­lion in wages, taxes and sub­si­dies. So, does that mean less invest­ment for car­bon-effi­cient tech ? A team of resear­chers from Gold­man Sachs recent­ly publi­shed a report “The decar­bo­ni­sa­tion tool­kit and what it will mean for air­lines.” They conclude that decar­bo­ni­sa­tion of the sec­tor will remain a focus for air­lines and poli­cy­ma­kers alike post-covid and assess the poten­tial impact on air­line growth and financials. 

How has the pan­de­mic impac­ted the sector ?

Vene­tia Baden-Powell. Covid-19 has resul­ted in the dee­pest civil avia­tion traf­fic reces­sion in his­to­ry. We fore­cas­ted a ~70% drop in air traf­fic in Europe in 2020, mul­tiple times worse than in 1991, 2001 or 2009. The knock-on effect for employ­ment in the sec­tor has also been sizeable, with air­lines announ­cing layoffs equal to 10–30% of their work­forces. At these traf­fic levels, air­lines burn signi­fi­cant cash flow : across five of the lar­gest air­lines in Europe, we fore­cast ~€14 bil­lion cash burn in 2020. Finan­cial stress has requi­red air­lines to raise capi­tal, either govern­ment-backed (e.g. Air France, Luf­than­sa) or via the equi­ty mar­ket (e.g. IAG, easy­Jet, Rya­nair). In Europe, direct aid pro­vi­ded or pled­ged across air­lines was ~€30 billion. 

How car­bon inten­sive is the sec­tor and is a low-car­bon future a rea­lis­tic pros­pect for air­lines fol­lo­wing the pandemic ?

The ans­wer to this is nuan­ced, which we explore in depth in our report. Pre-pan­de­mic, avia­tion accoun­ted for 4% of EU green­house gas emis­sions, up from 2% in 1990, dri­ven by signi­fi­cant traf­fic growth (2x GDP his­to­ri­cal­ly). While the increase in emis­sions has been miti­ga­ted by impro­ve­ments in air­craft effi­cien­cy, the sec­tor remains one of the most CO2 inten­sive and has lag­ged other indus­tries in redu­cing its inten­si­ty. This explains why poli­cy­ma­kers are focu­sed on the sec­tor from a car­bon pers­pec­tive, in par­ti­cu­lar in the wake of large-scale govern­ment finan­cial sup­port for the industry.

That said, fol­lo­wing the traf­fic drop we fore­cast in 2020 (~70%), aviation’s share of emis­sions could fall to 1–2%, all else equal. Given we don’t expect a return to 2019 traf­fic levels until the mid-2020s, this means poli­cy­ma­kers no lon­ger need to curb abso­lute acti­vi­ty levels for the sec­tor, but rather refo­cus on incen­ti­vi­sing effi­cien­cy gains and sus­tai­nable growth. Indeed, some announ­ced rescue packages for the sec­tor have “green” condi­tions, such as Air France. These include the reduc­tion of CO2 emissions/passenger km by 50% by 2030 (vs. 2005 levels), in part to be dri­ven by modal shift to rail on domes­tic routes and increa­sing bio­fuel use. 

A simi­lar res­ponse can be seen in Aus­tria fol­lo­wing Aus­trian Air­lines’ sup­port package, where the govern­ment plans to increase taxes on short-haul flights, intro­duce a price floor of €40 on any air ticket and invest more in rail. These poli­cies are like­ly to be com­ple­men­ted by struc­tu­ral shifts in consu­mer and cor­po­rate demand. Ove­rall howe­ver, new tech­no­lo­gies to drive low or ultra-low car­bon avia­tion won’t be avai­lable until post-2030. These include new pro­pul­sion tech­no­lo­gy such as hydro­gen and engine hybridisation/electrification. 

What impact could the decar­bo­ni­sa­tion levers avai­lable to poli­cy­ma­kers & air­lines have as the sec­tor recovers ?

The main levers being dis­cus­sed are incre­men­tal taxa­tion, rail pro­mo­tion and fleet rene­wal. Announ­ced pas­sen­ger taxes on EU short-haul could increase low cost car­rier fares by ~15%, which we esti­mate could trans­late into a mid-single digit % hit to demand and the­re­fore emis­sion. These will be imple­men­ted along­side grea­ter rail invest­ment. For example, a €40bn “Renais­sance of Rail Invest­ment” package is being consi­de­red under the EU’s Green Deal. We esti­mate that up to 15% of EU air traf­fic net­works are at risk from rail substitution.

Final­ly, a more orga­nic way for the sec­tor to reduce its car­bon foot­print near-term would be through fleet rene­wal. Full adop­tion of new gene­ra­tion air­craft could reduce emis­sions by near­ly 20%, all else equal. While covid has lowe­red the sector’s near-term invest­ment capa­ci­ty to buy new, effi­cient planes, we believe medium-term fleet rene­wal plans are unli­ke­ly to change. This reflects the impor­tance of fleet rene­wal in main­tai­ning an airline’s com­pe­ti­tive posi­tion, par­ti­cu­lar­ly in a sub­dued demand and fare envi­ron­ment. In fact, covid has gene­ral­ly ser­ved as a cata­lyst to retire inef­fi­cient air­craft with many air­lines expec­ting to run smal­ler, more effi­cient fleets medium-term.
