Industry faces additional €820 billion cost to decarbonise European aviation in line with net zero by 2050

To achieve the European aviation sector’s ambition of achieving net zero emissions by 2050, additional expenditures amounting to €820 billion (0bn) are required between 2018 and 2050, finds a study commissioned by five industry associations. These additional or ‘premium’ costs, mostly to be spent on alternative fuels, are on top of business-as-usual (BAU) expenditures, such as fleet renewal, which are required for the net zero transition. BAU expenditures over the 2018-2050 period are estimated at €1,068 billion, bringing the total expenditures towards reaching net zero at just under €1.9 trillion. The report just published, ‘The price of net…
Ryanair starts using SAF on all flights from Amsterdam’s “quieter and cleaner” Schiphol

Airline sustainability-linked finance to pick up from a low level, expects credit ratings agency

Global credit ratings business DBRS Morningstar says airlines have raised only $5 billion in sustainability-linked finance since 2018 but expects this to pick up as the aviation sector needs to invest around $175 billion annually to achieve net zero by 2050. In addition to the possible increase in funding, benefits of raising sustainable financing include enhancing ESG credibility and the potential to lower the cost of funding, explains DBRS in a client report. It says sustainability-linked bonds (SLBs) and transition bonds are likely to emerge as the key instruments of choice for the sector. However, airlines’ key performance indicators…
Should aviation be given preferential access to scarce land and clean energy resources for SAF, questions paper

An academic analysis of 12 roadmaps for decarbonising the global aviation industry finds they place a heavy reliance on biogenic fuels in the medium-term and synthetic e-kerosene in the longer term but largely omit a number of fundamental problems with sustainable aviation fuels, says a new science-led paper. Realising these roadmaps could require 9% of global renewable electricity and 30% of sustainably available biomass by 2050, with significant energy losses as SAF production is energy intensive and comes with a risk of clean energy displacement. Additional effects omitted in most roadmaps relate to the decadal time lags in re-sequestering…

A Ryanair deal with global energy group Repsol and the launch by Italian carrier ITA Airways of its ‘Fly with SAF’ programme, together with the signing of an agreement with logistics provider DB Schenker, and a Neste agreement with World Fuel Services are among a number of new European sustainable aviation fuel initiatives. Ryanair and Repsol have signed a MoU to advance the supply of SAF at airports used by Ryanair across Spain and Portugal. The ITA programme offers freight forwarders and shippers the possibility of supporting the purchase of SAF and thus reducing their CO2 emissions while shipping…
New reports highlight the costly challenge of transitioning to hydrogen and electric aviation

Two new reports have highlighted the considerable costs and logistics of transitioning air transport to novel propulsion aircraft, both emphasising the need for urgent action to enable the switch. A report by the World Economic Forum (WEF) as part of its Target True Zero initiative indicates that by 2050, the aviation industry will need to invest between $700 billion and $1.7 trillion to provide sufficient infrastructure for hydrogen, battery-electric and hybrid-electric aircraft. It argues the foundation elements must be in place by 2025 and says new partnerships are essential between the aviation sector and energy suppliers. A parallel report…
