The United States has voiced deep concern over a European Commission proposal to extend carbon costs to international flights departing from Europe. The EU plan would apply its Emissions Trading System to flights landing in countries up to 5,000 kilometers away, a threshold that excludes direct flights to the US. Washington blocked a similar EU expansion in 2012 and is now analyzing the proposal while warning it will protect American consumers and businesses. This policy dispute highlights ongoing tensions between carbon pricing for aviation and international trade. The EU argues that aviation emissions must be priced to meet climate goals, but the US sees the move as an extraterritorial tax. The outcome could set a precedent for how carbon markets apply to cross-border sectors like shipping and aviation.
