What are airlines doing to reduce emissions?

Promoting alternatives to air travel Increasing aircraft fuel efficiency. Developing more sustainable aviation fuels–whether liquid fuels or electricity. Removing carbon from the atmosphere through investment in renewable energy, carbon credits, and nature-based climate solutions.



In 2026, the aviation industry is under intense pressure to reach "Net Zero" by 2050, focusing on a three-pronged strategy: Sustainable Aviation Fuel (SAF), fleet modernization, and cabin reconfiguration. SAF, made from renewable waste sources, can reduce life-cycle emissions by up to 80% and is being blended into fuel supplies at major hubs. Airlines are also accelerating the retirement of older, four-engine jets in favor of ultra-efficient models like the Airbus A350 and Boeing 787-9. A striking new 2026 study in Nature Communications suggests that removing premium business-class cabins—which are up to five times more carbon-intensive than economy—could slash emissions by 75%. Many carriers are also implementing "operational efficiencies" such as weight reduction (using lighter seats and digital manuals), taxiing with a single engine, and using AI-driven flight planning to find more direct routes and favorable winds to burn less fuel.

We're making the current fleet lighter and more efficient and using new air traffic control techniques to save emissions. For example, landing using a continuous descent into an airport saves at least 150kg of CO2 per flight. Adding wingtip devices to an aircraft can reduce fuel use by 4%.

Voluntary passenger and cargo offset programs Offsets can be sourced from various types of project activities, including, for example, wind energy, clean cook stoves, methane capture forestry and other emissions-reducing, avoidance, or removal projects.

The five-part strategy includes fleet renewal, operational efficiency, novel propulsion, sustainable aviation fuel (SAF), and carbon offsetting technology.

Aviation contributes about 3 percent of all carbon emissions worldwide, which would make it sixth in the world if it were a country. The airline industry's contribution to the climate problem is worse than that, however, if we consider that flight also produces pollution other than carbon.

As a solo rider, driving a car wouldn't help lower your emissions — it would be higher than air travel, at 120 pounds of CO2. Though if you had four people in the car, the air pollution you'd emit would fall to just 30 pounds of CO2 per passenger.

So, if you're traveling with three or more people, driving is the better option, and here's why: Three people on the cross-country flight would account for 1.86 tons of carbon emissions (0.62 tons of CO2 x 3), compared to the total 1.26 tons of carbon the vehicle would produce (ignoring that the extra weight would ...

Aviation accounts for around 2.5% of global CO2 emissions, but 3.5% when we take non-CO2 impacts on climate into account. Flying is a highly controversial topic in climate debates. There are a few reasons for this. The first is the disconnect between its role in our personal and collective carbon emissions.

Low prices and an ever-expanding route network make it possible: 9 billion passengers are expected in the air by 2050. Thus, the passenger volume in aviation of the future will more than double compared to the current level.

Turkish Airlines has been crowned the 'Most Sustainable Flag Carrier Airline' in World Finance's Sustainability Awards 2023, having won the same award last year.

Airplanes burn fossil fuel which not only releases CO2 emissions but also has strong warming non-CO2 effects due to nitrogen oxides (NOx), vapour trails and cloud formation triggered by the altitude at which aircraft operate.
