What pollutes more cars or planes?

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 ...

Planes Remain A Problematic Means Of Transport 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.

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.

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 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.

The Burning of Fossil Fuels Most 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.

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.

Taking a seven-day cruise is more than three times as carbon-intensive as flying and staying abroad.

Unfortunately, truly sustainable air travel is not yet possible. While fuel economy is improving throughout the aviation industry, flying is still inherently carbon-intensive.

MORE DETAILS

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.

That is equal to 10% reduction in all greenhouse gases produced by a typical two-adult, two-car household. By eliminating one car and taking public transportation instead of driving, a saving of 30% of carbon dioxide emissions can be realized.
