Willie Walsh warns extending EU carbon costs to global flights could trigger retaliation

IATA head Willie Walsh has warned that extending Europe's emissions trading scheme to cover international flights could provoke retaliation from major economies like the US and China. The move would raise costs for airlines such as Aer Lingus on transatlantic routes and risk trade disputes. Walsh argues that unilaterally expanding carbon charges beyond the European Economic Area undermines global climate cooperation and puts European carriers at a competitive disadvantage. The debate highlights the tension between regional carbon pricing and international aviation emissions.
