Airlines say they’re acting on climate change. The research suggests otherwise

If you’re a traveller who cares about reducing your carbon footprint, are some airlines better to fly with than others?

Several of the world’s major airlines have announced plans to become “carbon neutral”, while others are trialling new aviation fuels. But are any of their climate initiatives making much difference?

Those were the questions we set out to answer a year ago, by analysing what the world’s largest 58 airlines – which fly 70 per cent of the total available seat-kilometres – are doing to live up to their promises to cut their climate impact.

The good news? Some airlines are taking positive steps. The bad news? When you compare what’s being done against the continued growth in emissions, even the best airlines are not doing anywhere near enough.

More efficient flights still drive up emissions

Our research found three-quarters of the world’s biggest airlines showed improvements in carbon efficiency – measured as carbon dioxide per available seat. But that’s not the same as cutting emissions overall.

One good example was the Spanish flag carrier Iberia, which reduced emissions per seat by about 6 per cent in 2017, but increased absolute emissions by 7 per cent.

For 2018, compared with 2017, the collective impact of all the climate measures being undertaken by the 58 biggest airlines amounted to an improvement of 1 per cent. This falls short of the industry’s goal of achieving a 1.5 per cent increase in efficiency. And the improvements were more than wiped out by the industry’s overall 5.2 per cent annual increase in emissions.

This challenge is even clearer when you look slightly further back. Industry figures show global airlines produced 733 million tonnes of CO₂ emissions in 2014. Falling fares and more people around wanting to fly saw airline emissions rise 23 per cent in just five years.

What are the airlines doing?

Airlines reported climate initiatives across 22 areas, with the most common involving fleet renewal, engine efficiency, weight reductions and flight path optimisation. Examples in our paper include:

  • Singapore Airlines modified the Trent 900 engines on their A380 aircraft, saving 26,326 tonnes of CO₂ (equivalent to 0.24 per cent of the airline’s annual emissions);
  • KLM’s efforts to reduce weight on board led to a CO₂ reduction of 13,500 tonnes (0.05 per cent of KLM’s emissions).
  • Etihad reports savings of 17,000 tonnes of CO₂ due to flight plan improvements (0.16 per cent of its emissions).

Nineteen of the 58 large airlines I examined invest in alternative fuels. But the scale of their research and development programs, and use of alternative fuels, remains tiny.

As an example, for Earth Day 2018 Air Canada announced a 160-tonne emissions saving from blending 230,000 litres of “biojet” fuel into 22 domestic flights. How much fuel was that? Not even enough to fill the more than 300,000-litre capacity of just one A380 plane.


Carbon neutral promises

Some airlines, including Qantas, are aiming to be carbon neutral by 2050. While that won’t be easy, Qantas is at least starting with better climate reporting; it’s one of only eight airlines addressing its carbon risk through the systematic Task Force on Climate-related Financial Disclosures process.

About half of the major airlines engage in carbon offsetting, but only 13 provide information on measurable impacts. Theses include Air New Zealand, with its FlyNeutral program to help restore native forest in New Zealand.

That lack of detail means the integrity of many offset schemes is questionable. And even if properly managed, offsets still avoid the fact that we can’t make deep carbon cuts if we keep flying at current rates.

What airlines and governments need to do

Our research shows major airlines’ climate efforts are achieving nowhere near enough. To decrease aviation emissions, three major changes are urgently needed.

  • All airlines need to implement all measures across the 22 categories covered in our report to reap any possible gain in efficiency.

  • Far more research is needed to develop alternative aviation fuels that genuinely cut emissions. Given what we’ve seen so far, these are unlikely to be biofuels. E-fuels – liquid fuels derived from carbon dioxide and hydrogen – may provide such a solution, but there are challenges ahead, including high costs.

  • Governments can – and some European countries do – impose carbon taxes and then invest into lower carbon alternatives. They can also provide incentives to develop new fuels and alternative infrastructure, such as rail or electric planes for shorter trips.

How you can make a difference

Our research paper was released late last year, at a World Travel and Tourism Council event linked to the Madrid climate summit. Activist Greta Thunberg famously sailed around the world to be there, rather than flying.

Higher-income travellers from around the world have had a disproportionately large impact in driving up aviation emissions.

This means that all of us who are privileged enough to fly, for work or pleasure, have a role to play too, by:

To really make an impact, far more of us need to do all three. The Conversation

Urgently needed: Timely, more detailed standardized data on US evictions

Last week the Eviction Lab, a team of eviction and housing policy researchers at Princeton University, released a new dashboard that provides timely, city-level US eviction data for use in monitoring eviction spikes and other trends as Covid restrictions ease. 

In 2018, Eviction Lab released the first national database of evictions in the US. The nationwide data are granular, going down to the level of a few city blocks in some places, but lagged by several years, so their use is more geared toward understanding the scope of the problem across the US, rather than making timely decisions to help city residents now. 

Eviction Lab’s new Eviction Tracking System, however, provides weekly updates on evictions by city and compares them to baseline data from past years. The researchers hope that the timeliness of this new data will allow for quicker action in the event that the US begins to see a wave of evictions once Covid eviction moratoriums are phased out.

But, due to a lack of standardization in eviction filings across the US, the Eviction Tracking System is currently available for only 11 cities, leaving many more places facing a high risk of eviction spikes out of the loop.

Each city included in the Eviction Tracking System shows rolling weekly and monthly eviction filing counts. A percent change is calculated by comparing current eviction filings to baseline eviction filings for a quick look at whether a city might be experiencing an uptick.

The tracking system also provides a more detailed report on each city’s Covid eviction moratorium efforts and more granular geographic and demographic information on the city’s evictions.

As part of their Covid Resource, the Eviction Lab together with Columbia Law School professor Emily Benfer also compiled a scorecard for each US state that ranks Covid-related tenant protection measures. A total of 15 of the 50 US states plus Washington DC received a score of zero because those states provided little if any protections.

CityMetric talked with Peter Hepburn, an assistant professor at Rutgers who just finished a two-year postdoc at the Eviction Lab, and Jeff Reichman, principal at the data science research firm January Advisors, about the struggles involved in collecting and analysing eviction data across the US.

Perhaps the most notable hurdle both researchers addressed is that there’s no standardized reporting of evictions across jurisdictions. Most evictions are reported to county-level governments, however what “reporting” means differs among and even within each county. 

In Texas, evictions go through the Justice of the Peace Courts. In Virginia they’re processed by General District Courts. Judges in Milwaukee are sealing more eviction case documents that come through their courtroom. In Austin, Pittsburgh and Richmond, eviction addresses aren’t available online but ZIP codes are. In Denver you have to pay about $7 to access a single eviction filing. In Alabama*, it’s $10 per eviction filing. 

Once the filings are acquired, the next barrier is normalizing them. While some jurisdictions share reporting systems, many have different fields and formats. Some are digital, but many are images of text or handwritten documents that require optical character recognition programs and natural language processors in order to translate them into data. That, or the filings would have to be processed by hand. 

“There's not enough interns in the world to do that work,” says Hepburn.


Aggregating data from all of these sources and normalizing them requires knowledge of the nuances in each jurisdiction. “It would be nice if, for every region, we were looking for the exact same things,” says Reichman. “Instead, depending on the vendor that they use, and depending on how the data is made available, it's a puzzle for each one.”

In December of 2019, US Senators Michael Bennet of Colorado and Rob Portman of Ohio introduced a bill that would set up state and local grants aimed at reducing low-income evictions. Included in the bill is a measure to enhance data collection. Hepburn is hopeful that the bill could one day mean an easier job for those trying to analyse eviction data.

That said, Hepburn and Reichman caution against the public release of granular eviction data. 

“In a lot of cases, what this gets used for is for tenant screening services,” says Hepburn. “There are companies that go and collect these data and make them available to landlords to try to check and see if their potential tenants have been previously evicted, or even just filed against for eviction, without any sort of judgement.”

According to research by Eviction Lab principal Matthew Desmond and Tracey Shollenberger, who is now vice president of science at Harvard’s Center for Policing Equity, residents who have been evicted or even just filed against for eviction often have a much harder time finding equal-quality housing in the future. That coupled with evidence that evictions affect minority populations at disproportionate rates can lead to widening racial and economic gaps in neighborhoods.

While opening up raw data on evictions to the public would not be the best option, making timely, granular data available to researchers and government officials can improve the system’s ability to respond to potential eviction crises.

Data on current and historical evictions can help city officials spot trends in who is getting evicted and who is doing the evicting. It can help inform new housing policy and reform old housing policies that may put more vulnerable citizens at undue risk.

Hepburn says that the Eviction Lab is currently working, in part with the ACLU, on research that shows the extent to which Black renters are disproportionately affected by the eviction crisis.

More broadly, says Hepburn, better data can help provide some oversight for a system which is largely unregulated.

“It's the Wild West, right? There's no right to representation. Defendants have no right to counsel. They're on their own here,” says Hepburn. “I mean, this is people losing their homes, and they're being processed in bulk very quickly by the system that has very little oversight, and that we know very little about.”

A 2018 report by the Philadelphia Mayor’s Taskforce on Eviction Prevention and Response found that of Philadelphia’s 22,500 eviction cases in 2016, tenants had legal representation in only 9% of them.

Included in Hepburn’s eviction data wishlist is an additional ask, something that is rarely included in any of the filings that the Eviction Lab and January Advisors have been poring over for years. He wants to know the relationship between money owed and monthly rent.

“At the individual level, if you were found to owe $1,500, was that on an apartment that's $1,500 a month? Or was it an apartment that's $500 a month? Because that makes a big difference in the story you're telling about the nature of the crisis, right? If you're letting somebody get three months behind that's different than evicting them immediately once they fall behind,” Hepburn says.

Now that the Eviction Tracking System has been out for a week, Hepburn says one of the next steps is to start reaching out to state and local governments to see if they can garner interest in the project. While he’s not ready to name any names just yet, he says that they’re already involved in talks with some interested parties.

*Correction: This story initially misidentified a jurisdiction that charges $10 to access an eviction filing. It is the state of Alabama, not the city of Atlanta. Also, at the time of publication, Peter Hepburn was an assistant professor at Rutgers, not an associate professor.
