Are planes damaging the environment?

Emissions from aviation are a significant contributor to climate change. 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.



Aviation is a significant contributor to global climate change, accounting for approximately 2.5% to 3.5% of total global CO2 emissions. However, the "total impact" is actually higher because planes release nitrogen oxides (NOx), water vapor, and soot at high altitudes, which create contrails and cirrus clouds that trap heat in the atmosphere. These "non-CO2 effects" can double or even triple the warming influence of the fuel alone. In 2026, the industry is under intense pressure to reach "Net Zero by 2050," leading to the rapid adoption of Sustainable Aviation Fuel (SAF) and more efficient engine designs. Despite these technological leaps, the sheer volume of global air travel continues to grow, often outpacing the gains in fuel efficiency. For environmental data projects, it is important to note that a single long-haul flight can produce more CO2 per passenger than the average person in many developing nations produces in an entire year, making aviation one of the most carbon-intensive activities an individual can undertake.

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.

Trains. Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.

Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.

Aviation is responsible for between 2pc and 3pc of global carbon emissions. And Ms Thunberg continues to refuse to fly because of the impact on the environment.

CO2 emissions from aviation fuel are 3.15 grams per gram of fuel [1], which gives CO2 emissions from a Boeing 737-400 of 115 g per passenger per km. At a cruising speed of 780 km per hour [Wikipedia, 28.2. 08], this is equivalent to 90 kg CO2 per passenger per hour.

Driving vs. Flying By the Numbers The overall fatality risk is 0.23% — you would need to fly every day for more than 10,000 years to be in a fatal plane crash. On the other hand, the chances of dying in a car collision are about 1 in 101, according to the National Highway Traffic Safety Administration (NHTSA).

Compared to flying, using the train emits on average six times less GHG 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.

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.

“A private jet is the most polluting form of transport you can take,” says Matt Finch, the UK policy manager for Transport & Environment. “The average private jet emits two tonnes of carbon an hour.

If you can't walk or cycle, then public transport is usually your best option. Trains are particularly low-carbon ways to travel. Taking a train instead of a car for medium-length distances would cut your emissions by around 80%. Using a train instead of a domestic flight would reduce your emissions by around 86%.

If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.
