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.

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 ...
Just exactly how bad is flying really? Air travel accounts for 2.5% of global carbon emissions. In the US, flying accounted for 8% of transportation emissions, but less than 3% of total carbon emissions.
Flights are energy-intensive and depend on fossil fuels. Subsidies from fuel taxes give the airline industry an unfair advantage over other transportation modes. Consumers don't see the true environmental costs of their air travel because low flight prices don't reflect their environmental impact.
Top polluting sector: fossil fuelsIt is no surprise that the fossil fuels sector is the most polluting in the world. Despite this knowledge, emissions from fossil fuels keep increasing. After a brief decline during the Covid 19 pandemic, they grew by 1% in 2022, reaching 40.5 gigatons of CO2.
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.
“The global aviation industry produces around 2% of all human-induced carbon dioxide (CO2) emissions. Aviation is responsible for 12% of CO2 emissions from all transports sources, compared to 74% from road transport.”
Your odds of being in an accident during a flight is one in 1.2 million, and the chances of that accident being fatal are one in 11 million. Your chances of dying in a car crash, conversely, are one in 5,000. Want answers to more key questions in aviation? Check out the rest of our guides here!
While most people think driving a car is better for the environment than flying in an airplane, that's not necessarily true because airplane engines are getting much more efficient.
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.
Walk, bike or take the train for the lowest footprintUsing a bike instead of a car for short trips would reduce your travel emissions by around 75%. If you can't walk or cycle, then public transport is usually your best option. Trains are particularly low-carbon ways to travel.
The luxury sports car brand Bugatti received the highest NEDC with an average of 0.52 kg/km — much higher than any other brand. In second place was Rolls Royce with 0.35 kg/km, followed by Lamborghini and Ferrari with similar NEDC data. But vehicles don't have to be expensive to produce high levels of pollution.
The plan is to have greener aircraft ferrying passengers around the world sometime in the 2030s. The first test flight of Boeing's experimental plane is expected in 2028. But the NASA-Boeing project isn't the only effort to make flight more environmentally sustainable.
Unfortunately, truly sustainable air travel is not yet possible. While fuel economy is improving throughout the aviation industry, flying is still inherently carbon-intensive. Advancements in biofuels and electric planes could cut aviation emissions dramatically, but they're still a long way from large-scale adoption.
