Are airplanes worse for the environment than cars?

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.

Finally, the plane is the most polluting means of transport and the one that generates the most greenhouse emissions.

Rail transport may well be the most environmentally responsible way to travel, other than walking and biking.

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.

“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.”

In fact, unless you're looking to venture from Los Altos to LA off-road through state parks the whole way—in a Hummer with Tonka-truck mud tires—driving is generally greener than flying.

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 main difference between flying and driving to a vacation is time spent. Benefits and drawbacks vary for either; driving can make hard-to-reach areas accessible, but risks traffic and high gas prices. Flying, meanwhile, allows you to multitask, but you're at the whim of airlines.

Flying produces an inconceivable amount of C02 emissions and air pollution. For those that don't know, CO2 (carbon dioxide) is one of the key greenhouse gases that contribute to global warming – flying produces a whole lot of it.

Flight cancellations, delays, lost baggage, smaller seats, higher prices, fuller flights, more connections, fewer destinations. For passengers, air travel gets more and more miserable by the year. Meanwhile, bankruptcies and mergers have meant competition is at an ebb.

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.

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.

If you take the train, then you'll cut carbon dioxide (CO2) by half compared to the plane. A key reason is that the train (or the diesel bus) may be a big carbon emitter, but it's designed to carry a lot of passengers, so the per capita emissions are a lot lower.

Ships are more environmentally friendly than planes, as greenhouse gasses emitted when using planes are much higher. Since planes emit these greenhouse gasses in the stratosphere, they considerably affect atmospheric chemistry. So, these plane emissions have a worse environmental impact than that of ships.

Vehicle emissions, fuel oils and natural gas to heat homes, by-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are the primary sources of human-made air pollution.
