Aviation industry decision to weaken CORSIA climate plan could break ICAO’s own rules


Aviation Industry Decision to Weaken Climate Plan Could Break Own Rules

Countries attending the UN’s aviation body meeting this week look set to weaken the only international policy to address the climate impact of aircraft. But the way the decision is being made could be in violation of the organisation’s own rules.

The International Civil Aviation Organisation (ICAO) has for decades been responsible for addressing the rising climate impact of international aviation, and agreed the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) in 2016.

The scheme has been widely criticised for likely delivering only “modest” emissions reduction, and could now be weakened further, as ICAO is expected by this Friday to decide on a change to the baseline of CORSIA, lowering the level of emissions reductions airlines would have to aim for.

But the ability of the ICAO’s Council to legitimately make this decision has been called into question, as the organisation continues to be criticised for its opaque practices.


ICAO plans to change the baseline to only 2019 emissions levels, rather than an average of 2019 and 2020 levels. That means the baseline will be far higher, owing to the huge drop in aviation emissions in 2020 due to the coronavirus pandemic. Airlines will therefore be able to emit far more before the scheme’s obligations to offset emissions growth past this baseline come into practise.

Under most post-COVID growth scenarios, changing the baseline would delay CORSIA‘s start for three to five years, according to an analysis by the Environmental Defense Fund (EDF), which argues this could effectively eliminate airline offsetting obligations until 2028 or later. A separate analysis by the Oeko Institute found changing the baseline could reduce the overall mitigation achieved through CORSIA by 25 to 75 percent.

But there are questions about the legitimacy of the 36-country ICAO Council taking a decision that would undermine its main climate policy for several years.

Big changes to CORSIA are supposed to only be decided at the larger, 193-strong, ICAO Assembly, which usually takes place every three years. The next Assembly is not due until 2022.

Technically speaking, the Council does not formally take decisions which can change CORSIA, they just recommend things to the Assembly,” says Gilles Dufrasne, senior policy officer at Carbon Market Watch. “Since the establishment of CORSIA was through an Assembly resolution, the Council (a lower level body) cannot change it.”

The discussion of the baseline change at the ongoing Council session was initially prompted by a request from the International Air Transport Association (IATA) lobby group. It asked for the baseline to be changed and said that ICAO should make the decision to do this by 30 June 2020.

This demonstrates the power of the lobby group within the Council, says Chris Lyle, an international aviation consultant who worked at ICAO for almost 30 years.

ICAO‘s job is to protect and promote aviation, and IATA tells ICAO what to do: in essence, that’s what happens,” he says. “IATA has asked for the base year to be brought to 2019 for obvious reasons. Because including 2020, they’d really have to start buying a lot of offsets.”

IATA points to paragraph 16 of CORSIA’s rules as proof the Council is allowed to make this change. But Annie Petsonk from EDF disputes this reading. She says the paragraph allows the Council to decide criteria for triggering changes, not to decide on these changes itself.

DeSmog understands that ICAO has itself done a legal analysis on whether the Assembly rather than the Council needs to take the final decision on the baseline issue.

Speaking to DeSmog, Green MEP Jutta Paulus notes it still is not known whether the ICAO legal bureau has delivered an opinion on whether the Council can change the baseline. “It is a pity that they are only publishing the minutes of their Assemblies, which only take place about every three years,” she says. “We would wish for more transparency.”

Petsonk says the opinion that comes out of ICAOs legal department on the baseline change matters because, “it’s that paragraph on which IATA is hanging its hat, saying that the Assembly gave the Council the authority to do something as extraordinary as in effect suspending CORSIA for six years,” she says. “This is what the effect of the baseline decision would be. This would be a much smaller number [of states], potentially a simple majority of the Council – 19 states – undoing a decision that was taken by 190.”

It would also mean countries who may have spoken in defence of stronger climate measures won’t have a voice ahead of the decision, adds Petsonk.

Earlier this month, the EU, usually the most progressive voice at ICAO advocating for stronger climate policy, decided to support the baseline change. “It was very disappointing to see that the EU really backed the airline industry asks and obviously didn’t even put up any kind of fights to try to maintain the system as it is,” DuFrasne says.

The final decision on the baseline change is expected by the end of the session on 26 June. With few countries opposing it and no campaigners present at the Council session, it appears highly likely to pass at the Council level. Whether this will be the final decision, it seems, depends on the ICAO’s legal analysis.

But even if the Council outcome is established as just a recommendation to the Assembly, the decision on the baseline change could effectively already be made, says DuFrasne. “The ICAO Council is very powerful because what it recommends is very likely to then be adopted by the Assembly,” he says. “The fact that the Council cannot formally change the baseline doesn’t really change the situation of all these negotiations happening behind closed doors.”

The changes mean “we’re just going from a bad scheme to an extremely bad scheme,” he says.


Media and civil society are blocked from attending the ICAO Council session, meaning its impossible to know which countries are pushing what.

ICAO confirmed to DeSmog that the Council session will discuss the impact of COVID-19 on air traffic and CORSIA, but refused to give any more information, saying the Council session is closed to the media. “It is not unusual for diplomatic activity to take place without the media present,” ICAO’s press office told DeSmog when asked why it was barring the press.

Campaigners have long criticised the lack of transparency at ICAO and its refusal to give access to media and campaigners to scrutinise its decisions. “Airlines have led this massive campaign [to get public bailouts], saying ‘we’re vital to society’,” says DuFrasne. “At the same time the closed doors of ICAO allow them to strongly lobby to destroy the only international climate policy that’s regulating them.”

ICAO has restrictive policies on access to documents and meetings, no freedom of information policy, and binds NGO observers by non-disclosure agreements. Its official Twitter account has been known to bizarrely attack and block climate campaigners and researchers who scrutinise ICAO’s policies, accusing these people of “fake news” and “spam”.

The focus of the ICAO Council session on changes to CORSIA makes the transparency question particularly pertinent, says Jo Dardenne, an expert on sustainable aviation at NGO Transport & Environment (T&E). “It’s quite questionable for a handful of member states to make decisions behind closed doors overnight on a scheme already agreed by over 190 countries,” she says.

‘Final blow’ to aviation climate plan as EU agrees to weaken rules

There had been hopes that the EU would insist on keeping more effective means of reducing carbon emitted by airlines. The current proposals by ICAO, in their CORSIA scheme, are too weak to be effective. The EU now say they will back the CORSIA scheme, which means watering down the rules.  Airlines want the baseline period, from which to measure airline carbon emissions for the CORSIA scheme, to be the two years, 2019 and 2020. But 2020 is going to be a year of atypically low airline activity. So they want the base line period to be just 2019. That means giving airlines a free pass to pollute for the next 3 to 6 years depending on the speed of the Covid recovery. That is what the EU has now agreed to, having initially stood out against it. So airlines could save $15 billion in carbon offsetting costs, paying nothing till 2024. This weakening of the scheme would further damage the credibility of the CORSIA offsetting scheme, which is widely regarded as weak and not aligned with the Paris Agreement goals. It will now become essentially meaningless.  The ineffective CORSIA scheme undermines many governments’ stated intentions to bolster climate ambition.

Open letter to ICAO – the CORSIA scheme should not be weakened, just because of Covid

Thirteen organisations concerned with aviation carbon emissions and carbon trading, have written to ICAO to ask that they stick to the intentions for how the CORSIA scheme is set up, and do not weaken it. The stated purpose of CORSIA is to help the international aviation sector achieve “carbon-neutral growth from 2020”. It is due to use as a baseline the aviation CO2 emissions from 2019 and 2020. However, with the Covid pandemic, airline carbon emissions will be much lower than anticipated this year. If ICAO used 2019 and 2020, the amount of carbon the sector could emit, and the cost of emitting it, would be far lower than anticipated. So IATA wants to change the rules, so the carbon baseline only considers 2019, not including 2020, which would result in significantly lower offsetting requirements for airlines compared to the current CORSIA design. In fact, under most recovery scenarios, the change sought by IATA would eliminate all offsetting requirements for the duration of the CORSIA pilot phase and potentially several years thereafter. The rules need to be adhered to.

IATA calls for change in CORSIA baseline to protect airlines from future higher offsetting requirements

Fri 3 Apr 2020
By GreenAir online

As a result of the coronavirus pandemic, IATA has called on the ICAO Council to change the baseline calculation used for the CORSIA offsetting scheme for international aviation emissions.

Under rules agreed by ICAO, the baseline is set at the average emissions for the years 2019 and 2020. For the 15-year duration of CORSIA starting next year, airlines are required to purchase offsets to cover any annual growth in emissions above the baseline.
The collapse in global air traffic as a result of the outbreak, with demand unlikely to recover this year, will lead to significantly lower 2020 emissions. This in turn will lower the baseline considerably than was previously projected and result in much higher anticipated offsetting requirements and therefore costs once the sector returns to previous levels, says IATA.
It requests the Council to make the change no later than the end of June.

In a position paper, IATA says the baseline must be adjusted “to ensure the sustainable development of international aviation and avoid an inappropriate economic burden on the sector.” It recommends that only emissions for 2019 be used for calculating the baseline.

In support of its justification for a change in the baseline, the IATA paper quotes paragraph 16 of the A40-19 CORSIA resolution passed at the last ICAO Assembly in 2019,  “… on the need to provide for safeguards in the CORSIA to ensure the sustainable development of the international aviation sector and against inappropriate economic burden on international aviation, and requests the Council to decide the basis and criteria for triggering such action and identify possible means to address these issues …”.

The IATA paper argues: “Allowing the use of 2019 emissions as an alternative would preserve the environmental benefits that were forecast to be achieved through CORSIA as the adjusted baseline would remain more stringent than what the baseline would have been without the Covid-19 crisis.”

The airline trade body is also concerned that countries already signed up to join the voluntary pilot and first phases of CORSIA, and those still considering joining, may reconsider their positions in order to protect their airlines from potential higher compliance costs if no change is made to the 2019/20 calculation. States have until June 30 to notify ICAO of their intention to join the scheme from the beginning or decide to discontinue their voluntary participation.

Accordingly, IATA urges the Council to take a decision on a baseline adjustment before this date at the latest.

IATA also calls on ICAO to urge States to extend the May 31 deadline for the submission by aeroplane operators of their 2019 verified emissions report until at least the end of October 2020. It argues Covid-19 travel restrictions and confinement measures in many countries “have made it impossible for verification bodies to conduct verification activities.”

Historically, air transport activity has rebounded quickly after previous global crises but IATA’s March 24 Covid-19 impact assessment points to the potential for a deep financial recession following the outbreak that would delay the air transport sector’s recovery to previous levels. If this was to be the case and a 2019 only baseline applied to CORSIA, this could considerably reduce airline demand for offsets, at least in the 2021-23 pilot phase.Although it is too early to predict the impact of the pandemic on total emissions from international aviation this year, IATA’s current forecast is for a 38% fall in global passenger traffic in 2020. According to IATA, global emissions in 2019 – from domestic as well as international flights – totalled 915 million tonnes. Emissions from international aviation activity, which will be covered by CORSIA, account for around 60% of the global total.
