The French government has unveiled plans for a new “eco-tax” on all flights from airports in France, to begin in 2020. The amount of the tax will depend on the type of ticket being purchased, with a fee of €1.50 (about $1.70) on economy class tickets and up to €18 (about $20.20) for business class tickets. A similar Air Passenger Duty is already in place in the UK. The tax will only apply to outgoing flights and not to those flying into the country. The money will be used to invest in less-polluting transport systems such as rail. The International Air Transport Association immediately condemned the move, with a statement saying that “this tax is misguided.” The statement said that since 1990 airlines have reduced carbon emissions per passenger by 50 percent and beginning in 2020 will be paying to offset all the growth in emissions.
