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.

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.
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.
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.
Overview. Aviation is one of the fastest-growing sources of the greenhouse gas emissions driving global climate change. In fact, if the entire aviation sector were a country, it would be one of the top 10 carbon-polluting nations on the planet.
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.
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.
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.
The first ever ranking of total airline emissions has the German carrier Lufthansa at the top with 19.11 million tonnes of CO2, closely followed by British Airways with 18.38 million.
Flights emit 500 grams of carbon dioxide/metric tons of cargo per kilometer of transportation. However, ships emit only between 10 to 40 grams of carbon dioxide per kilometer. The carbon footprint of airplanes is 20 to 30 times more than ships.
Trains are nearly always the winning option over moderate-to-long distances; If travelling internationally, going by train or boat is lower-carbon than flying; Electric vehicles are nearly always lower-carbon than petrol or diesel cars.

Airplanes become more fuel efficient with every generation, and there are plenty of ways old planes can be spruced up. Winglets can be added on to the end of wing's, reducing drag and reducing fuel consumption by 6 percent.
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.
Cigarette butts — whose filters contain tiny plastic fibers — are the most common type of plastic waste found in the environment. Food wrappers, plastic bottles, plastic bottle caps, plastic grocery bags, plastic straws, and stirrers are the next most common items.
