A carbon tax or frequent flyer levy
Taxes or levies would ensure those who fly are faced with a price tag that reflects the impact of what they’re doing. The German website DW has quoted David Hodgkinson, an associate professor of law at the University of Western Australia, arguing that a carbon tax is needed, especially given the complexity of other cross-border strategies for reducing emissions. “People understand it,” he said. “They might not like it, but they understand the properties of a tax. … Most people, and even the airline industry, would accept that there needs to be some form of price on aviation emissions.”
