Comparing greenhouse gas emissionsEssentially, one long flight releases the equivalent of nearly 14 percent of the annual emissions from your car. The same route, when driven, will result in the release of 1.26 tons of carbon emissions.

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.
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.
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.
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.
The cramped conditions and long periods of being less active on a flight can cause pain, stiffness or swelling of your legs. Being less active can lead to slow blood flow in your veins which increases your risk of developing a blood clot, known as deep vein thrombosis (DVT).
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.

It all depends on your destination. If you're traveling within your state or a state over, driving is most likely going to be faster. If you're traveling more than 300 miles, flying will probably get you there quicker.
For the shortest trip, driving is slightly more economical than flying. But for the longer cross-country trip, flying is far cheaper. And keep in mind that this only considers solo drivers. Families or friends traveling in one vehicle can save money by driving, even on longer routes.
So why does flying feel more dangerous when it's obviously far safer than driving? Part of our fear may stem from the perception that, while plane crashes may be rarer than car accidents, they are more deadly.
In fact, when choosing between planes, trains, and automobiles, Americans prefer traveling by plane least. A survey of 2,000 Americans revealed that three in four (73%) people feel that road tripping is a much more pleasant experience than flying.
In fact, if the entire aviation sector were a country, it would be one of the top 10 carbon-polluting nations on the planet. Air travel is also currently the most carbon intensive activity an individual can make.
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.
