When comparing the two, driving is a better option for the environment as it doesn’t lead to a lot of emissions. Flying, on the other hand, produces so much emission that it contributes up to 3% of the total global emissions.
Despite this, the aviation industry is one of the fastest and largest growing industries, something that has led to the prediction that in the next 10 years the number of emissions from that industry will have doubled.
Different factors contribute to the number of emissions produced by a vehicle or airplane. They include distance, speed, number of passengers, type and amount of fuel as well as the type of engine. Planes tend to have more of each of these factors and as such, pose more danger to the environment. Also, planes cover long distances in a short period which means they produce more carbon on every trip. This is done at high altitudes which leads to more impact than carbon produced at lower levels.
However, it is also believed that in some cases the emissions produced by a car equals that produced by a plane. For example, a 2L petrol car traveling from London to Bilbao is believed to produce 0.26 tones of carbon monoxide. This is almost the same as a plane travelling in the opposite direction, producing 0.28 tones of emissions.
Planes that fly short distances seem to have fewer emissions than those that fly long distances. This stems from the fact that those flying long distances have to go to higher altitudes than those flying for short distances.
However, short flights can still cause as much harm if they are frequent. This shows that whether one takes multiple short flights or takes one long flight, the effect will be the same. You can find more at this website.
While cars seem to be more eco-friendly than planes, some are energy efficient and are therefore preferable. Trains seem to be the most ideal options since they use electricity which doesn’t lead to carbon emissions.
