Abstract
When you think about the causes of climate change, what comes to mind? Do you think of gasoline-powered cars? Or do you think about coal and natural gas power plants? It turns out that a big source of greenhouse gas emissions is flying. To prevent Earth from becoming too warm, many countries have set net-zero emission goals. So, the aviation industry needs to make changes. We analyzed the amount of greenhouse gas emissions produced in nine different scenarios in the years up to 2050. Each scenario included a change in the demand for flying, a change in the efficiency of the airplanes, and a change in the type of fuel used. We found making changes to these factors can reduce greenhouse gas emissions. However, the aviation industry will also need to invest in carbon dioxide removal from the atmosphere. With these changes, it is possible for the aviation industry to reach net-zero emissions by 2050!
