Just in time for summer, Germany is planning to impose a new tax on air travel to try and reduce their budget deficit.

Speaking from Berlin on Monday, Chancellor Angela Merkel revealed a four-year plan to reduce the country’s debts and lending part of that responsibility to the nation’s air travelers.

The levy will yield 1 billion euros ($1.2 billion) a year in revenue for the federal government, the government said in an e-mailed statement. It will be paid by passengers departing from German airports, with the level depending on factors such as the flight’s noise level and fuel consumption, according to the statement.

Germany’s national levy will be replaced by a Europe-wide measure once aviation is subject to European Union carbon- emissions trading, the statement said.
