Research Reveals Little Achieved by Airlines Claiming Climate Change Action

Published

If you’re a traveler 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 analyzing what the world’s largest 58 airlines – which fly 70% of the total available seat-kilometers – 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% in 2017, but increased absolute emissions by 7%.



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%. This falls short of the industry’s goal of achieving a 1.5% increase in efficiency. And the improvements were more than wiped out by the industry’s overall 5.2% 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% 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% 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% of KLM’s emissions).
  • Etihad reports savings of 17,000 tonnes of CO₂ due to flight plan improvements (0.16% 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.

  1. All airlines need to implement all measures across the 22 categories covered in our report to reap any possible gain in efficiency.
  2. 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.
  3. 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:

  1. reducing our flying (completely, or flying less)
  2. carbon offsetting
  3. for essential trips, only flying with airlines doing more to cut emissions.

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

Changes Brought On by Coronavirus May Help Tackle Climate Change

Stock markets around the world had some of their worst performance in decades this past week, well surpassing that of the global financial crisis in 2008. Restrictions in the free movement of people is disrupting economic activity across the world as measures to control the coronavirus roll out.

There is a strong link between economic activity and global carbon dioxide emissions, due to the dominance of fossil fuel sources of energy. This coupling suggests we might be in for an unexpected surprise due to the coronavirus pandemic: a slowdown of carbon dioxide emissions due to reduced energy consumption.

Based on new projections for economic growth in 2020, we suggest the impact of the coronavirus might significantly curb global emissions.

The effect is likely to be less pronounced than during the global financial crisis (GFC). And emissions declines in response to past economic crises suggest a rapid recovery of emissions when the pandemic is over.

But prudent spending of economic stimulus measures, and a permanent adoption of new work behaviours, could influence how emissions evolve in future.

The world in crisis

In just a few short months, millions of people have been put into quarantine and regions locked down to reduce the spread of the coronavirus. Around the world events are being cancelled and travel plans dropped. A growing number of universities, schools and workplaces have closed and some workers are choosing to work from home if they can.

Even the Intergovernmental Panel on Climate Change has cancelled a critically important meeting and will instead hold it virtually.

The International Energy Agency had already predicted oil use would drop in 2020, and this was before an oil price war emerged between Saudi Arabia and Russia.

The unprecedented coronavirus lockdown in China led to an estimated 25% reduction in energy use and emissions over a two-week period compared to previous years (mostly due to a drop in electricity use, industrial production and transport). This is enough to shave one percentage point growth off China’s emissions in 2020. Reductions are also being observed in Italy, and are likely to spread across Europe as lockdowns become more widespread.

The emission-intensive airline industry, covering 2.6% of global carbon dioxide emissions (both national and international), is in freefall. It may take months, if not years, for people to return to air travel given that coronavirus may linger for several seasons.

Given these economic upheavals, it is becoming increasingly likely that global carbon dioxide emissions will drop in 2020.

Coronavirus is not the GFC

Leading authorities have revised down economic forecasts as a result of the pandemic, but so far forecasts still indicate the global economy will grow in 2020. For example, the Organisation for Economic Cooperation and Development (OECD) downgraded estimates of global growth in 2020 from 3% (made in November 2019) to 2.4% (made in March 2020). The International Monetary Fund has indicated similar declines, with an update due next month.

Assuming the carbon efficiency of the global economy improves in line with the 10-year average of 2.5% per year, the OECD’s post-coronavirus growth projection implies carbon dioxide emissions may decline 0.3% in 2020 (including a leap year adjustment).

But the GFC experience indicates that the carbon efficiency of the global economy may improve much more slowly during a crisis. If this happens in 2020 because of the coronavirus, carbon dioxide emissions still could grow.

Under the worst-case OECD forecast the global economy in 2020 could grow as little as 1.5%. All else equal, we calculate this would lead to a 1.2% decline in carbon dioxide emissions in 2020.

This drop is comparable to the GFC, which in 2009 led to a 0.1% drop in global GDP and a 1.2% drop in emissions. So far, neither the OECD or International Monetary Fund have suggested coronavirus will take global GDP into the red.

The emissions rebound

The GFC prompted big, swift stimulus packages from governments around the world, leading to a 5.1% rebound in global emissions in 2010, well above the long-term average.

Previous financial shocks, such as the collapse of the former Soviet Union or the 1970s and 1980s oil crises, also had periods with lower or negative growth, but growth soon returned. At best, a financial crisis delays emissions growth a few years. Structural changes may happen, such as the shift to nuclear energy after the oil crises, but evidence suggests emissions continue to grow.

The economic legacy of the coronavirus might also be very different to the GFC. It looks more like a slow burner, with a drop in productivity over an extended period rather than widespread job losses in the short term.

Looking to the future

The coronavirus pandemic will not turn around the long-term upward trend in global emissions. But governments around the world are announcing economic stimulus measures, and they way they’re spent may affect how emissions evolve in future.

There is an opportunity to invest the stimulus money in structural changes leading to reduced emissions after economic growth returns, such as further development of clean technologies.

Also, the coronavirus has forced new working-from-home habits that limit commuting, and a broader adoption of online meetings to reduce the need for long-haul business flights. This raises the prospect of long-term emissions reductions should these new work behaviours persist beyond the current global emergency.

The coronavirus is, of course, an international crisis, and a personal tragedy for those who have lost, and will lose, loved ones. But with good planning, 2020 could be the year that global emissions peak (though the same was said after the GFC).

That said, past economic shocks might not be a great analogue for the coronavirus pandemic, which is unprecedented in modern human history and has a long way to go.

House Passes Schiff’s Rim of the Valley Corridor Preservation Act

Published

on

WASHINGTON D.C. – Rep. Adam Schiff has applauded the bipartisan passage of The Rim of the Valley Corridor Preservation Act, which would add more than 191,000 acres of the Rim of the Valley Corridor to the Santa Monica Mountains National Recreation Area (SMMNRA). The bill passed the House on a bipartisan basis with 231 Yeas and 183 Nays

Schiff first introduced this legislation in 2017, and Senators Dianne Feinstein and Kamala Harris introduced companion legislation in the Senate. It recently passed out of the Senate Energy and Natural Resources Committee on a bipartisan basis.

“I am thrilled that the House of Representatives has passed the Rim of the Valley Corridor Preservation Act, legislation I have championed for nearly 20 years,” Congressman Schiff said. “Preservation of the open space in our communities is not only good for our environment, wildlife, and ecosystems, but it is beneficial for the health and well-being of residents of all ages. The Rim of the Valley corridor is an area of striking and breathtaking natural beauty, and we must do whatever we can to preserve that beauty for the benefit of LA residents, the millions each year who visit, and for generations to come.”

“Today’s vote in the House is a win for the Rim of the Valley Corridor and the millions of Los Angeles County residents living in the surrounding communities,” said Senator Feinstein. “Preserving this unspoiled terrain will protect sensitive habitat for California wildlife and open space to benefit local economies. I am glad that Congressman Schiff was able to pass it in the House and look forward to doing the same here in the Senate, where it has already advanced out of committee.”

“The Rim of the Valley corridor is home to some of Southern California’s most beautiful wildlife and landscapes,” said Senator Harris. “That is why we must take immediate steps to protect this area’s habitats and natural resources. I am grateful to Congressman Schiff for his leadership on this issue and I applaud the House of Representatives for prioritizing the preservation of this area so it can be enjoyed by future generations. I look forward to working with my colleagues in the Senate to get this bill across the finish line.”

The proposed expansion is based on a six-year study of the region completed by the National Park Service in 2015. This legislation would expand the SMMNRA to include many, but not all, of the land included in the study. The lands included within the expansion will be known as the Rim of the Valley Unit and stretches from the Simi Hills and Santa Susanas to the Verdugos and on to the San Gabriel Mountains. The bill will enable NPS and the local community to better protect natural resources and habitats, and provide members of the community with improved access to nature for recreational and educational purposes.
