This week, we’ll be discussing ways to address air pollution. One idea is introducing environmental taxes on air travel. Such taxes also referred to as ecological taxes or green taxes, are extra charges that get added to the price of airplane tickets. Money collected from these taxes could be invested in environmentally friendly technologies or in promoting other cleaner modes of transportation. Do you think there should be an environmental tax on air travel? Why or why not?
Andrew
We should impose environmental taxes on air travel. These taxes might encourage people to find cheaper, more eco-friendly ways to get places. In my country, many people use planes to fly a short distance because flights are relatively cheap, when they could just as easily take a less polluting form of transportation.
Claire:
Additional taxes on air travel will do little to solve the problem of air pollution. Airplane tickets would become more expensive, punishing passengers without incentivizing airlines to become more environmentally friendly. The airlines should pay the price to protect the environment, not their customers.
