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.

When comparing the number of emissions per person, it may seem like flying is better than driving. However, when more people share the drive, emissions per person are reduced, making driving more environmentally friendly than flying. But if you are driving cross-country solo, you are better off taking to the skies.
In fact, if everyone in the world took just one long-haul flight per year, aircraft emissions would far exceed the US's entire CO2 emissions, according to ICCT analysis. For those of us that do fly, it is likely to make up a significant slice of our personal carbon footprint.
Aviation accounts for around 2.5% of global CO2 emissions, but it's overall contribution to climate change is higher. This is because air travel does not only emit CO2: it affects the climate in a number of more complex ways.
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.
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.
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.
British Airways is one of the most environmentally conscious airlines in the world, focusing on reducing carbon emissions per passenger, reducing noise per flight, and minimizing waste by increasing material reuse and recycling.
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.
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.
One out of every six flights that the Federal Aviation Administration (FAA) handles are flown by private jets. Although fewer private aircraft fly compared to commercial jets, the carbon pollution is more. According to the study, private jets emit at least 10 times more pollutants than commercial planes per passenger.
Cruise ships, huge compared to other vessels, end up burning more heavy fuel oil, one of the dirtiest fossil fuels on the market. This oil contains dangerous levels of sulfur and heavy metals etc. It is estimated that cruise ships use, on average, 150 tons of heavy fuel oil every day.
