AI Summary

The European Union has made a partial move towards taxing international flights by extending its Emissions Trading System (ETS) to cover some of these flights, as well as private jets and smaller ships. This development is notable because it represents a step forward in the EU's efforts to address emissions from aviation. However, the overall revision of the ETS has also been criticized for weakening the system, which could undermine European climate action and energy security. The implications of this move are unclear, but it appears that the EU is taking a cautious approach to addressing emissions from international flights, rather than implementing more comprehensive measures.
