When calculating my carbon footprint which was lower than average, I noticed that one part was higher, transportation. This surprised me because I take the bus to school and walk to close places often. What actually made that so high was because of air travel. My family and I normally go out of the USA once a year but I did not know how much travel and air travel. My carbon footprint is significantly increased by travel, especially air travel. The International Energy Agency (IEA) estimates that transportation causes around 24% of the world's CO2 emissions, with aircraft playing a significant role. As much CO2 emissions as the typical human emits in a year may be produced by a single long-haul trip. Carbon emissions are also a result of the energy needed to build and maintain aviation infrastructure, including airports and aircraft.
Some, however, can take action to lessen the carbon footprint of their trip. For instance, choosing environmentally friendly transportation options like trains or buses, if you are not traveling over water, can cut CO2 emissions. Additionally, avoiding connecting flights in favor of direct flights and flying economy instead of business or first class helps lessen the environmental impact of air travel. Additionally and most importantly, several airlines provide carbon offset programs enabling customers to finance environmental initiatives that lower carbon emissions to make up for their travel-related emissions.
