Is flying really that bad for the Environment?

Air travel accounts for about 4 percent of human-induced global warming, and the United Nations warns that airplane emissions are set to triple by 2050. Planes are becoming more efficient, but our appetite for air travel is outpacing the industry's environmental gains.

Released at high altitudes, aviation emissions have between two and four times the impact of comparable ground-source emissions. If we take these additional impacts into account, we see that aviation represents about 3.5% of the warming impact caused by humans.

Driving vs. Flying By the Numbers The overall fatality risk is 0.23% — you would need to fly every day for more than 10,000 years to be in a fatal plane crash. On the other hand, the chances of dying in a car collision are about 1 in 101, according to the National Highway Traffic Safety Administration (NHTSA).

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.

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.

Low prices and an ever-expanding route network make it possible: 9 billion passengers are expected in the air by 2050. Thus, the passenger volume in aviation of the future will more than double compared to the current level.

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.

For those who want to reduce their emissions from flying, one tip is to take fewer trips that are longer in duration, as opposed to numerous short trips. The emissions from frequent flying can quickly add up.
