EU reviews CORSIA effectiveness; pressure mounts over treatment of non‑EU flights under ETS The European Commission is conducting a summer review of CORSIA’s effectiveness and whether to extend it, revisiting how aviation emissions on non‑EU flights should be handled. The move is already renewing industry debate over extending or reframing the EU ETS scope for routes beyond EU airspace.
