Planes burn up more fuel than cars per journey, and therefore produce more carbon dioxide.

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 ...
As you add more passengers, the amount of emissions your party produces increases on a flight. In contrast, the amount of greenhouse gas emissions, which trap heat and lead to global warming, produced decreases per person when driving. The break-even point for driving vs. flying in this example is 2.03 people.
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.
The Burning of Fossil FuelsMost of the air pollution takes place due to the incomplete burning of fossil fuels. These include coal, oil, and gasoline to produce energy for electricity or transportation.
Car emissions are a major source of pollution. Cars and trucks emit twenty percent of all greenhouse gases emitted in the United States[1], which is the second largest greenhouse gas emitter in the world.
For example, a study by the University of Michigan Transportation Research Institute states the energy intensity of car transportation is on average 57% higher than air transports. In other words, a car emits more CO2 than the average planes because they consume more energy to transport the same amount of passengers.
Take a non-stop flightI know that direct flights normally come in that much more expensive, but since a large part of emissions come from take-off and landing, non-stop flights are often the best sustainable flying option.
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.
“In 50 years, we will still be flying, and it will be sustainable,” says Palacios. “But we're in a fast-moving environment.” Until then, flight free activists will remain on the ground. “The only way to fly sustainably here and now is not to fly at all,” says Rosén.
But just how severe is their impact on the climate? Unfortunately, taking a cruise takes a toll on the planet. Your trip will average anywhere from 700-1000 pounds of carbon emissions a day, which is much higher than flying, driving or a traditional 'land' vacation.
