To achieve “net zero carbon” by 2050, the global aviation sector would have to “cancel” the carbon emissions of entire industrialized countries ... every single year
"But I be done seen about everything..."
Hey! I’m Chris, the Principal of CJSC, LLC. When I worked for the United States (US) Federal Aviation Administration, I helped create the environmental modeling tool that’s now required for aviation environmental compliance across that country. I also participated in some of the first International Civil Aviation Organization discussions to create a global carbon dioxide (CO2) standard for aircraft.1
This issue is not about that stuff.

The “row” started in 2012… or did it?
On January 1st of 2012, the European Union (EU) did something that outraged airlines and their home countries across the globe: It unilaterally added international aviation to its Emissions Trading System (ETS) carbon market, covering all CO2 emissions from flights that depart from or arrive to EU member states. The US had tried to block the EU’s action the prior year… and failed.2 In response to the 2012 addition of international aviation to the EU’s ETS, China blocked its airlines from buying Airbus aircraft (according to Airbus, anyway3 ) and over 26 countries dubbed “the coalition of the unwilling” met in Moscow that February to discuss “options for retaliatory action against the EU.”4
The EU had launched the ETS in 2005 as a “cap and trade” system to limit allowable greenhouse gas emissions and enable affected entities to trade “carbon credits” — the rights to emit specific amounts of greenhouse gases.5 The first phase of the ETS covered only power generators and other “energy-intensive industries;” adding international aviation to this, especially without the express written prior approval of other countries, was supposed to be a no-no. That’s because, for decades, most of the world's countries (193 to date) had established aviation environmental standards through a little-known body of the United Nations known as the International Civil Aviation Organization (ICAO).6 ICAO member countries are supposed to "promulgate" (formally establish) aviation environmental standards in their home countries only after those standards are agreed by ICAO -- and there was no ICAO standard for an international aviation CO2 market on January 1st of 2012.

22 years of talking
The idea of a carbon market for international aviation goes back to at least 1998. That year, ICAO released resolution A32-8 to study emissions-related charges, taxes, and emissions trading7 , all known in ICAO parlance as “market-based measures” (MBMs). In 2010, ICAO released resolution A37-19 resolving to research the feasibility of establishing global market-based measures for aviation.8
The EU’s 2012 addition of international aviation to its ETS accelerated discussions on MBMs rather severely. In fact, a European Commission staff working document gently stated the following in 20139 :
The EU has a strong history of multilateralism and has continuously sought to move forward the ICAO action on MBMs. To facilitate the negotiations in the run-up to the 2013 ICAO Assembly, the EU adopted the "stop-the-clock" decision No. 377/2013/EC to temporarily defer the enforcement of the EU ETS compliance obligations for flights to and from most 3rd countries for 2012. This has created momentum for the 2013 ICAO Assembly to move forward on the development of a global MBM and an agreement on a framework for national and regional MBMs (hereafter "MBM Framework") that would apply until a global MBM is implemented in 2020.
English translation: ICAO should commit in 2013 to implement a global MBM for aviation by 2020… or else!
And indeed, ICAO in 2013 released resolution A38-18, which stated that ICAO "[d]ecides to develop a global MBM scheme for international aviation.”10 In 2016, ICAO began developing the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) for launch in 2020,11 to enable “carbon-neutral growth” from that year forward.12
22 years of discussions to launch a global carbon market for aviation. ICAO sure took its fill of sweet, sweet time.
CORSIA works by requiring aircraft operators subject to CORSIA to purchase and then “cancel” specific amounts of “eligible emissions units” – that is, CO2 carbon credits available in a CORSIA-approved global carbon market – every year.13 14 Purchasing a credit is supposed to help provide funding to projects around the world that avoid, reduce, or remove CO2; the price of each credit is supposed to be set by the supply of credits vs. the demand in the carbon market. The “cancellation” of such credits (also called “retirement” in some sectors) is supposed to occur after an independent verifier documents that the representative CO2 has indeed been avoided, reduced, or removed by a project. Cancellation of credits could happen instantly or could instead take years, depending on the type of project.
Aviation’s decarbonization challenge… and cost
In October of 2021, over 300 airlines carrying a majority of the world's air traffic committed to "achieve net zero carbon by 2050.”15 16 But even as the industry made that commitment, aviation CO2 emissions were continuing to grow. In 2022 alone, those emissions were almost 800 million metric tons17 : about the same amount of CO2 released by the entirety of Canada, or Germany, or Mexico, or Saudi Arabia that same year.18 Also that year, ICAO published a report on the feasibility of a “long-term aspirational goal” (LTAG) for global aviation CO2 reductions.19 This report stated that aviation CO2 emissions in the year 2050 (in the LTAG “mid” traffic forecast) could be over 1.5 billion metric tons — more than that released by Brazil or Indonesia in the year 2022.20
ICAO’s most ambitious technology, operations, and “sustainable aviation fuels” (SAF) deployment scenario in the LTAG document, named “IS3,” leaves 203 million metric tons of “residual” CO2 that would have to be offset every year by 2050 for global aviation to reach net zero carbon. For context, that’s roughly the same amount of CO2 that Qatar or Ethiopia produced in 2022. ICAO’s least ambitious technology, operations, and SAF deployment scenario, named “IS1,” leaves almost one billion metric tons of “residual” CO2 that would have to be offset every year by 2050 — about the same amount of emissions released by Japan or Iran in 2022.
Imagine having to “cancel” the entirety of Japan’s or Iran’s CO2 emissions every single year. Yes, that’s what CORSIA is theoretically intended to make possible. If global advancements in technology, operations, and SAF don’t measure up to that “least ambitious” LTAG IS1 scenario, then the carbon emissions needing yearly “cancellation” will be even higher.
Now, where exactly will we find enough offsetting projects to cancel that much CO2… every single year? After all, international aviation isn’t the only sector that has committed to “net zero”…
Of course, none of these CO2-reducing efforts come for free. In the LTAG IS1 scenario, the global aviation sector (including national governments, airlines, manufacturers, fuel producers, etc.) would have to invest the following cumulative amounts of money between 2020 and 205021 :
$165 billion to $560 billion in new aircraft technology
$53 billion in fuel-saving operational techniques
$1.2 TRILLION in SAF investment, plus an additional $1.1 TRILLION in “incremental cost” (vs. the cost of fossil jet fuel) borne by the airlines to purchase SAF
But hey, the aircraft operators would also save about $1 trillion in total through reduced fuel costs (due to new aircraft technology and operational techniques) so their incremental costs basically balance out!
In the LTAG IS3 scenario, the global aviation sector would have to invest the following cumulative amounts of money between 2020 and 205022 :
$335 billion to $1.9 trillion in new aircraft technology
$181 billion in fuel-saving operational techniques
$3.2 trillion in SAF and other fuels investment, plus an additional $4 trillion in airline incremental cost and an additional $125 billion in airport infrastructure investment
A “trillion” sure sounds like a big number. (Cue the “a trillion dollars by 2050 isn’t actually all that much money” critics…) For context, the gross domestic product (GDP) of the United States of America was $25 trillion in 2022, according to the World Bank.23 Or put another way, $3.2 trillion in SAF investment between 2020 and 2050 means investing, on average, the entire 2022 GDP of Puerto Rico, or Angola, or Kenya, or the Dominican Republic every year within that 30-year time frame.
Oh: by the way, CORSIA compliance for airlines is an additional cost on top of all of the above.
And also by the way, the entire text above only addresses CO2. There are whole other worlds of sustainability, from water to air quality to human rights, that “net zero carbon by 2050” doesn’t even begin to cover.
Questions for you to think about
If buying carbon credits is cheaper than buying SAF or new aircraft technologies, would the natural response of airlines be to "decarbonize" through CORSIA offsetting rather than through new fuels? What kinds of offsetting projects would be needed to cancel all the associated CO2 emissions?
Does the global aviation sector "deserve" the investment that would be needed to achieve net zero carbon in 2050? Yes: we as a global society can invest in more than one thing at once, but we do have limited resources needing allocation to many causes.
Perhaps you believe that the numbers in this article are entirely overblown — after all, it’s difficult to forecast how the aviation sector will perform even one year in advance, much less in the year 2050. So, let’s say that the actual dollar cost and offsetting requirements are “only” 1/10th the numbers presented in this article. If so, would your answers to the above questions change?
Finally: Is net zero carbon by 2050 really the way to achieve authentic global aviation sustainability? What does “authentic global aviation sustainability” look like to you?
