In 2012, it was undoubtedly the main reason for backing down: the EU had dropped its plan to cover all flights departing from and arriving in Europe under its carbon market scheme, following intense pressure from industry and major economies, not least the United States. It was the infamous ‘stop the clock’ to the full scope under the EU Emissions Trading System (ETS). Now, the end of what the Commission says will be the last derogation extension is around the corner. In 2026, the Commission will potentially propose to extend the EU ETS scope to all flights departing from Europe. The EU must not cave in to further intimidation tactics – including the trade war Trump is leading – and uphold its values and climate leadership.
